Stripper: Professionals Tips How to find the best tool (95 photos). A good set for stripping and ending wires The principle of stripping wires from isolation

In the arsenal of a good electrician is the most diverse tool. After all, high-quality installation of wiring often depends not only on knowledge and skills, but also from the presence of certain devices, as well as skills, how to contact them.

Even seemingly such a simple question, how to clean the wire from isolation, requires a certain set of tools. An experienced electrician has a tool for high-quality stripping of wires of any type and sections.

About the importance of the right sweep

For high-quality and reliable electrical connections, it is important not only to correctly perform a twist or spike. It is equally important to carefully clean the core of isolation. With a hurry or improper use of the tool, it is easy to damage (cut) the conductive core itself. This leads to a decrease in the cross section of the wire and a faster failure of the connection location: cliff or burning. As a rule, the wires used in everyday life and cables have a single-core or strain structure. Depending on this, various tools and methods can be applied to exemplate the speakers from isolation. We will consider the most frequently used of them, which are used by home and professional electricians to remove isolation.

Professional instrument

Professional electricians use a special device with a stripper (KSI). Such a tool can be three types:

1. Manual;
2. Semi-automatic;
3. Auto.

Consider their device in more detail.

Manual Stripper

Manual device is perhaps the most common stripper option. Several positive factors play their role here:

• Low weight;
• Compact size;
• Several additional features making this tool more versatile.

Such a stripper has several (usually up to seven) fixed gaps, which allow you to quickly clean the wire with a cross section from 0.25 to 2.5 mm. Of the additional features, the scissors on the cable and the function of the compression of tips are most useful.

One of the varieties of manual stripper, allows you to remove insulation from wires with a cross section from 0.6 mm to 2.6 mm

Semi-automatic ksy.

This tool also has a certain number of holes in which you need to insert the wire to remove the insulation. After that, it is enough to squeeze the handles: the sponges will clum down and will hold the wire, and the knife will force the isolation. As a result, the stripper will open, removing isolation.

The advantage of such a tool is the simplicity of design and ease of use. By minuses include some bulky and impracticality: additional functions are not provided. That is why such a device has not received widespread use even among professionals.

Semi-automatic ticks for removal of insulation KBT WS-03A

KSI car

Electricians who have to perform a large number of different connections every day, automatic strippers are used daily. Such a tool is extremely easy to operate: it is enough to start the wire into the workspace, and squeeze the handles. The device gently remove the braid from the wire, automatically determining the cross section of the vein.

Without configuration, such a tool works with a wire with a cross section from 0.2 to 6 mm2. It is worth noting that modern strippers have an adjustment screw that allows you to adjust the device to work with a wire of smaller diameter.

KBT WS-03A ticks automatically determine the wire section

In addition, the popular WS-04 stripper model has many additional features:

• The comb on the inside of the handles allow you to produce crimping in round terminals;
• Next to the combs are set knives for the cable, allowing you to quickly crop the ends of the wire;
• If necessary, you can set a limiter to remove the insulation, for example, 2 cm.

Multifunctional automatic stripper is designed to withdraw both single and double isolation. But it is worth noting that one layer of braid is removed in one operation. That is, to remove the double insulation, you must produce two manipulations.

Screw tools

But not everyone needs to clean dozens of wires daily. In addition, a high-quality professional tool is worth a decent money. Therefore, in everyday life, when it is necessary to cleanse a few ends, it is quite possible to do with undergraduate means and a tool that any owner has.

Stripping with a knife

The most popular tool for one-to-clean isolation is a regular knife. But its use is fraught with damage to cable veins. Therefore, the knife must not be kept directly, but at an acute angle to the wire and "comprising" the insulating layer. Using a knife, you need to be careful because they are easy to cut. A stationery knife is also often used, but it is still inconvenient to work, and it will easily break if the braid is very hard.

For cutting cables, a knife having a hook shape is often used. This knife has a wider blade, it is designed to cut insulation along the cable.

The knife in the shape of a hook for removing the isolation Knippex KN-1220165SB is used for longitudinal insulation cutting

Also produced a knife in the form of a special clamp. The wire is inserted under the clamping bar, where the blade is installed. Cressing the bar with a thumb, the knife is carried out on the braid, cutting it, after which the isolation is easily removed. It is worth such a knife about 200 rubles and is a fairly universal tool.

Such a knife is often used to remove insulation from UTP cable. Also on this device there is a device for the clip of the UTP cable in the socket and cross-panel

Sideboards

It is very convenient to use nippers, which are still called side windows. In order to quickly clean the wire from the insulation, the plugs must be kept in hand. It is better to take the nipples with the opposite side: so that the cutting edges are directed against the stroke. This will allow the blades to be easily crashed into a braid without disturbing the integrity of the vein. Such a method is easy to implement, and the pliers have each owner. Therefore, this way of stripping the wires was widely used.

Siderase - an integral tool of any electrician

Method of melting

The method for cleaning the isolation is most suitable for cleaning old wiring. The fact is that over time, the winding loses its elasticity, becomes tough and both fragile. If you use a mechanical tool, such as pliers or stripper, braid can crack anywhere.

In this case, you can use a soldering iron or device for burning wood. Preheated soldering iron braid melted in a circle, after which it is easily removed with nipples or passages.

The advantages of this method include the possibility of removing isolation with very thin wires without the risk of damage. Of the minuses, we note the presence of a caustic smoke when placing and, of course, electricity is required.

It is extremely recommended to remove the insulation to use teeth. This not only damages the dental enamel, but also can cause the defeat by static electricity accumulated during the installation process of wiring. It is not let easy, but very unpleasant.

How to clean some types of wire

Sometimes there is a need to connect not a conventional wire in a soft braid, and conductive conductors with a specific coating. An extraordinary approaches are required to withdraw such isolation. Let's look at some options.

Enameled wire

For stripping such insulation, two ways are used:

1. Mechanical method. For this method, it is best to use small emery paper. The paper segment is folded in half, then the wire will turn inside the sheet. Slightly squeezing with fingers sandpaper, the wire is stretched for a free end. Such manipulations should be continued until the enamel is completely erected. This method is suitable for enamelled wire with a cross section of more than 0.2 mm2;
2. The thermochemical method is often used by radio amateurs for cleaning enamel with wire with a cross section of less than 0.2 mm2. Its essence lies in the use of the soldering iron and chlorvinyl material (the ordinary insulating tape is suitable). A ribbon slice falls on a flat surface, the cut of the wire is stacked on top. Preheated soldering iron you need to slowly spend on the wire. The chlorine distinguished at the same time exceeds the enamelled coating from the wire.

Wire with fluoroplastic coating

Fluoroplast is a polymeric material, for a protective coating of wires is available as a narrow tape, which is tightly wound on a conductive core. Such insulation has high thermal resistance (up to 300 ° C), does not miss moisture and is suitable for use in various complex operating conditions.

It is possible to remove such a braid only by mechanical way. For this, on the one hand, the insulation is gently swashed along the wire, so as not to damage the core. As soon as the wire is denied, the insulation is assigned to the side and is cut into the desired length.

Coaxial cable

Such a cable is used to connect cable or satellite TV using the F-connector. When removing isolation from this conductor, caution should be taken: the veins are very thin and fragile, it is very easy to damage. Connect the connector in such a sequence:

1. The first layer of the winding is caught with a knife for a distance of 15 mm from the edge;
2. Rotating movements, an outcropped braid is removed from the cable;
3. Aluminum or foil winding bends onto the wire;
4. It is then removed insulation from the central vein to a distance of 10 mm from the edge;
5. After that, the connector turns onto the cable until it stops;
6. The central live should perform from a 2 mm connector.

Let's sum up

In conclusion, we note that the most correct way of stripping the wire is impossible. It is important here that the insulation is removed without damaging the conductive veins. Each method has the right to use in certain situations.

Separately, it is worth paying attention to the importance of working when the tension is removed. If there is no possibility to de-energize the wiring, all works are produced in rubber gloves and an isolated tool.

Tools for removing insulation from wires

With electrical installation of any complexity, there is almost always a need to clean the wires. Some try to do it with teeth, but it does not even have to talk about the absurdity of this method - it is necessary to use at least minimally suitable for these purposes to the device - knife, pliers, pliers or professional tools.

Electrician knife for cable cutting

As the electrical engineering develops, many methods of removing the insulating coating from conductors appeared. The most obvious is cutting or cutting with an insulating shell knife with its subsequent removal.

Many electricians still use this method if the specialized tool does not turn under hand. The electrical knife can be both self-made and industrialized for electrical installation.

We need practice and caution when removing isolation from wires, especially multi-core, with the help of these cutting tools. Since this is a rather troublesome process, professional electricians are rarely used for these purposes, but the electrical knife is almost indispensable when cutting cables, that is, when removing the upper layer of insulation.

removing the upper layer of insulation

A special popularity has dropped a knife with a heel on the edge, which slides on internal insulated cable veins, cutting an outer insulating layer.

This heel is gently inserted into the end of the cable and pushed from themselves or to himself, to whom it is more convenient, cutting the top protective coating with an acute cutting edge.

To make it convenient to insert the heel, the cable is compressed using pliers.

For security purposes, not to be hurt, it is recommended to always keep the cable with pliers in data manipulations.

Wiring stripping methods

With cable lives, insulation cover is removed by various methods and tools that are most suitable under a specific type of insulating coating.

Because for the installation of household wiring, the most frequent conductors with PCW isolation are used, then it will only be about tools suitable for this work, but before you mention some handicraft methods for removing insulating protective cover. Disturbing the best tools most often use knives of various designs.

Often, the insulating layer of PFV is paid using a soldering iron, after which it isolation with the help of pliers.

A significant disadvantage is a poisonous evaporation and corrosion of the soldier sting. Such heat treatment is also carried out using a lighter or heated nichrome thread.

Another way is to compress the wire with nipples and tightening isolation, with an excellent compression force, which is difficult to control - a little stronger, pressing the metal core can be easily born.

These methods are suitable for one-time stripping of several wires, but in professional activity, a corresponding tool for removing isolation is needed.

Principles of Stripping Conducting Core

There are two principles of removal from cable lives of the protective cover used in professional tools - this is cutting and gap isolation.

When cutting the cutting edge, without damaging the campsive core, cuts the protective layer in a circle, after which the resulting cut tube is removed from the conductor with some effort. This principle is used in a simple knife for removing isolation.

The wire is inserted into a semicircle of a suitable radius located on the presser plate, after which the tool turns several times around the veins and the insulating layer is pressed into the blade in a circle. A similar method is used in a different trimming tool - here the clamping force on the blade and the diameter of the cleaned wire manually is adjusted by pressure.

Other modifications:

The disadvantage of these tools is the time of operation and the possibility of damage to the metal core.

Gap and removal of insulation

This principle can be compared with the method of stripping wires with the help of teeth when a piece of squeezed insulation is removed from the rest of the coating when the force is applied along the conductor.

Similar professional tools are called strippers, they allow you to remove isolation very quickly, by pressing the handle, which makes them very beneficial with large volumes of the electromotion.

Stripper (STRIPER, a derivative word from the verb to Strip - to slander) is arranged in such a way that three functions are simultaneously carried out:

• Fixation of the cleaned wire;
• Compression (supervision) of the insulating layer;
• Tearing and tightening isolation effort.

The locking sponges have notches so that they can hardly hold the cable vein. The tearing sponges are equipped with grips that eat a plastic layer, partially damaging it when naked, thanks to which the insulation is broken in this place.

This stripper is equipped with a limiter, which rests on the wire, so all the conductors will be cleaned on the same distance that can be adjusted.

Implementing isolation The force is adjustable using the setup screw.

A similar principle of cleaning the wires was used in the Soviet Stripper, only the limiter was missing in it, and it was necessary to insert the wire into the appropriate semicircles.

Stripper using cutting blades

The principle of insulation isolate, followed by its removal used in the stripper of the company Knipex.

Here are the same functions as in the instrument described above, only instead of squeezing the PVV layer, it takes place, but a constructively given stripper made from reinforced carbon fiber.

The insulation removal algorithm occurs as follows - the insertion of the wires, its fixation, cutting and removal of the cover.

This tool also has an adjustment of the length of the insulation and the depth of the blades.

In this instrument, it is possible to cut cables.

In addition, with the help of this stripper, you can cut wires. Regardless of the method used, fixture or stripper, removing isolation, you should be very attentive and properly adjusted tool to remove the insulation so as not to damage the core that can then break away.

Tool for stripping insulation of wires and cables

The electrical installation of any complexity is almost always accompanied by a stripping of the ends of the wire. For these purposes, a variety of devices are used. What to choose a tool for stripping the insulation of the wires, and how to work, tell me the article.

Wire thickness and current value

At the value of the current passing through the conductor exceeding the calculated nominal values, the balance is violated in the operation of the power grid, which leads to overheating of the insulation layer, and at critical values \u200b\u200b- to the melting of the metal elements of the wires. In this principle, electric welding machines operate.

Reducing the thickness of the conductor leads to an increase in its electrical resistance, a decrease in operational characteristics. Such a wire will not withstand the required current loads, but with smaller values, it can work long enough. In addition, the mechanical properties are additionally reduced.

As the transverse section of the conductor is affected by the current amount passed through it, it is possible to determine using the Ohm law.

From the figure it is seen: if you make a large force on the knife, cutting the insulation layer, then the blade, after entering the metal, will break the cross-sectional area and the structure of the wire. How metal cuts clearly visible in the photo.

Tip: When removing the insulation layer from the wire, it is necessary to monitor the state of metal cores, not allowing scratches and cuts on it. Even with their insignificant depth, with time a significant decrease in the cross-section area may occur, which will cause failures and failures in the work of the equipment.

The principle of stripping wires from isolation

In professional tools, two removal principles from the protective coating cable are used:

• Gap. This method can be compared with the cleaning of the wires with teeth when a piece of insulation, sandwiched between the teeth, is removed from the rest of the coating layer with an effort directed along the conductor.
• Cutting. In this case, the cutting edge cuts over the protective layer in a circle, without damaging the conductive veins. Then, part of the cut tube is removed from the conductor with a small force.

Professional tools for removing insulation from wires are:

• Manual.
• Semi-automatic.
• Automatic.

To work with a small amount of wires at home, you can use simple ways of stripping them ends.

Simple Wire Stripping Methods

Removing isolation from cable ends can be performed in two ways:

• Thermal influence. In this case, heating the veins is used to the melting point of isolation. This is carried out:

1. Carriage of the insulating layer of the PSV soldering iron, and then removal of the coating with pliers. Large disadvantage - the presence of a poisonous evaporation and corrosion on the steering of the soldering iron.
2. Lighter.
3. Preheated thread of nichrome.

Such techniques are better used for thin, low power of the conductors, which are used in electronics, communication devices, audio equipment with multiple soft conductors working in chains, where voltage is about 5 volts.

Tip: Such methods should be used only with one-time stripping of a small amount of wires.

• Mechanical cutting. The method is based on removing the protective layer with cutting edges of the tool. At home, for these purposes it is best to use a knife for removing insulation from wires.

Electricians often make a knife with their own hands. For this:

1. Take a fragment from the saw blade of metal with a small blade.
2. Ichip it on the sandpaper to give the tool the shape of the sharp, thin wedge.
3. The handle is performed by a dense wiring of the wire, which is caused by several layers of the tape.

Such a web is perfectly cut off with a layer of polyvinyl chloride, but the wrong work with a knife easily damages the metal or aluminum metal, close to isolation.

Tip: When using such a self-made, the blade sharpening plane should be very gently directed at an acute angle to the cutting layer of isolation, which will allow when touching the tool to slide on it, and not crash.

How to quickly remove isolation from the copper wire at home, tells the video.

Tools for professionals

Professional tool for removing insulation from wires is:

• Forceps.
• Passatia.
• Pliers.
• Knives.

With some of them introduces the table:

How to use stripper

The principle of operation of the device is as follows:

• Sponges are originally crashed into isolation.
• Capture wires from two sides. On sponges there are special deep notches located at some angle.
• After crimping insulation, the sponges work as a plow, perform a translational movement, which leads to the deepening of the climb and retaining notes in isolation.
• A sharp sponge jerk diverges around. As a result, isolation, which can be easily removed.

Tip: To break the isolation, it is necessary to do just jerk, and not uniformly spreading the lipper sponges.

• For such a sharp jerk, the rear metal plate on the tool is covered with plastic lids. It contains a hole where the conical metal pin of a small size is included.
• When pressing a tool with some force on the handle, a small bend occurs at the base of the metal plate. As a result, it loses the engagement with the pin, which leads to a sharp discrepancy between sponges.
• Power adjustment The jerk is performed by a microfunction screw, changing the length of the pint.

Such a device for removing isolation from the wires is equipped with two pairs of sponges. When working, the ends of the stripped cable are placed in the working area of \u200b\u200bthe instrument, the insulation is insulated, and the sponges are removed from the veins.

For example, an instruction manual for removing insulation with automatic stripper with a wire cross section is 2.5 mm²:

• The wire is stacked until it stops between sponges.
• The handles are slightly compressed, which leads to the wires of the wire with sponges.
• When you click on the handle to the end, the insulation is removed.

Such a device for removing insulation from the wires is equipped with additional laying and protrusions for crimping tips. It is very convenient when it is necessary to urgently enhance the tip, and there is no normal crimper nearby.

However, it is not very convenient to use. There is also an insulation length limiter that needs to be cleaned.

So that there are no problems when scrolling the wires, several rules should be followed:

• To remove the coaxial cable shell, the process must be divided into two stages:

1. Remove the soldering iron outer shell, while sting you need to go through the longitudinal direction.

1. Remove the upper braid to get to the polyethylene insulation located on the central core. This isolation is easily removed by a knife or other tool.

• Clean the insulating layer of the enamelled wire is better than a knife, with a cross section of the vein more than 0.2 mm², or a soldering iron, for a smaller cross section. Enamel can be carefully removed by sandpaper, performing translational movements.
• The rubber coating is better to remove the special tool to remove isolation from the wire.
• To purify the shell in the middle of the long cable, it is better to use the electrical knife.
• Paper isolation from the cable, it is easier for a knife.

Removing isolation from wires is a responsible moment. A reliable electrical circuit system depends on the quality of the tool and qualifications of its owner.

Instruments. Strippers - Tools for removing insulation from wires - Drive2

The most important thing when removing isolation from the wires is not to damage the conductor itself and not damage isolation where it should remain. And also it is important to be quick, convenient and safe.

I have a few strippers, and I decided to make a small review:

Different strippers

The most ancient and proven option, which all electricians enjoy still from a long time, are these ticks to remove the insulation:

Ticks for removing isolation, adjustable with screw, handles are insulated up to 1000V

The principle of operation is very simple - the screws are configured to the necessary diameter of the conductor (with a small margin, so that during the removal of insulation does not scratch the conductor itself), then the wire is wrapped, you can check the ticks around the wire (to cut insulation in a circle):

Then just pull ticks on yourself - insulation is easy to remove:

Isolation is easy to remove

Such pliers are with uninsulated handles (cost cheaper), and there are insulated (red or red with yellow pens, inscriptions that there is insulation up to 1000V).

I have a model with insulated handles, and this is at the same time my easiest and at the same time the most expensive stripper - whether it cost 1200r or 1400r (despite the fact that the same look can be found for 600 and even for 300r).

The fact is that this one is made in Germany, everyone is so tested in a tension bath. The Chinese can lie on the insulation account, and if it is low quality and you will work under the current, you can kill. Well, of course, the hardness of steel and sharpening are also very good - you can easily clean the finest wiring.

Cons - if you work with different diameters of the wire, then all the time you need to either reconfigure the screw, or have several such ticks and confuse them. In addition, it is impossible to adjust the length of the insulation.

Pluses are reliability, indeliability, the possibility of removing isolation in hard-to-reach places where other strippers will not fit, and this is the only stripper from those that I know what can be working on a voltage.

He once recovered me very much when, at the cottage at the input to the house, FIGO was burned out of contact (a twist of copper with aluminum oxidized), and our electrician was just quarreled. I myself climbed the stairs, and using these insulated mites, as well as insulated passas, plug and screwdriver, could bite off, clean and restore contact, and be with the light before the arrival of this electrician.)

And one of his plus was found: it turns out that this stripper is capable of cleaning the incredibly subtle leashes that the rest of the stripper from this review is simply torn (the diameter of the insulation wiring is less than the milimeter)!

Let me remind you, this stripper is the most expensive of those in this review, and it is made in Germany - perhaps it is very carefully manufactured, and its cheap analogues are not capable of such, but nevertheless.

Here is another stripper, it is created specifically for removing the outer shell with round cables:

Very good and convenient tool, and it is simply indispensable for NYM type cable!

The only one, there are two types - with an extra knife (covered with a white translucent cap in the photo) and without it. So, this additional knife is absolutely not needed, in my opinion there were those times when the wires were crushed by knives, so it only interferes, better choose the model without it.

How this stripper works - a thin and very sharp blade is built in it, the production of which is regulated by a screw:

The screw is adjustable so that the blade cut the insulation but did not concern the wires in the cable. The device is put on the cable, clamping, turns around, and stretches to the end, cutting insulation.

Here are a video of a similar stripper:

I got a small trimming of an excellent cable with a bunch of first-graded copper wiring:

With this stripper, I easily showed them by removing the insulation:

It can be seen as the released blade cut all insulation

Now wires for radiomontage I will be provided for a long time!)

My darling! So much joy for 1000r!)

These strippers are produced under different stamps, I have seen such under the Lux brand, Weicon Super No. 5, kW and some more. There are about 1000r 1800r - Golden Middle. There are similar toes cheap, black with black blades - shit full, money for the wind. There is the same design of expensive professional 3-5 thousand rubles, with a huge resource for those who are just just and does that removes isolation from the wires - for home it is for nothing.

This stripper works very simply - set the length of the removable isolation (on many terminals, sockets, switches, etc. write to what length to take insulation for them:

On the terminal it is written that for it you need to set the length of removable insulation in 10 mm - we install by 10 mm)

After that, insert the wire inside to the limiter and in one movement removed the insulation. Nothing other than the length of removal is not needed at all.

Here is the video of his work:

The only minus is sometimes the remnants of the insulation are stuck in this stripper and have to be removed. This happens if it slowly compresses and squeeze the handles, but if you clean the quick movement - the insulation immediately departs and does not get stuck.

Probably strippers for 4-7 thousand rubles such lack are devoid, but it is important only to professional installers, who day and night removes insulation from the wires.)

But it can remove isolation from the finest and delicate wires, even to remove the outer shell first, and then insulation from the wires inside.

There are built-in nippers for wires up to 2 mm.

This is my favorite stripper, especially it is good for stranded wires.

Handles are very easily compressed - much easier than in the following type of stripper, which I will consider.

The following appearance is such a stripper:

Stripper kW - workhorse Sovdpovsky electrician)

Very common and not a new stripper design.

Here is the video of his work:

What is so good, that millions choose it?

First universality - it can clean the wires of different diameter, automatically adjusting.

Secondly, it is the most convenient stripper to work with popular with our flat wire:

Flat wire

This is the only stripper, which can carefully remove the external isolation from such a wire, as well as remove the insulation immediately from the two or three of its wires at the same time!)

I, unfortunately, was not under the hand of the Wedge of the VG type for a demonstration, I had to take what it was.

Usually, the insulation of the flat wire is removed by a knife or such a thing:

Usually a flat cable is separated by a knife or even such a thing.

What is uncomfortable, because at the end it turns out that:

The remnants of insulation have to cut with nipples

The remnants of isolation stick out so that they do not interfere, you need to cut off their impressions.

But! If you use the right stripper, then this is not required!)

The correctly selected tool makes the work easily, quickly and gently)

The result is quick, gently, safe:

Carefully and quickly, without delaying movements, outdoor insulation with a flat wire

Another stripper can take insulation from two or three wires simerly.

Unfortunately I did not have a suitable three-core wire at hand, but I think the principle is clear:

Simultaneous removal of insulation with 2 wires. No one else can!))

Very comfortable stripper for a three-core cable.)

I also liked it very much - although I first seemed to me coarsely, but it is for thin wiring, and the electrician for 220 volts, especially flat WDG and the like it brings it just gorgeous!)

As a bonus, there are built-in nippers and some kind of crimpera (tools for crimping) for isolated and uninsulated tips. It is uncomfortable to use, but if there is no normal shrimp at hand, but you need to enclose the tip is salvation.

There is also a limiter of the length of the heated isolation, which is usually removed immediately.)

Like this. There will be an opportunity to supplement the article, I will write about the stripper for a coaxial cable, about the stripper-crimper for telephone and Internet cable, as well as about the crimpers (tools for crimping cable lugs and sleeves).

I just say that the stranded wires after removing the insulation can not be pressed immediately without preparation, since it easily destroys individual veins.

It is necessary to pressed the stranded wires with isolated or uninsulated tips:

tip Isolated and Uninsulated

It is possible to see the crooked tip above, in the photo with the first ticks, I just have already achieved a limit of photos.)

NSHVI (tip pin sleeve insulated) Such a thing seems to be called, sold everywhere, if one such a tip must be clamped 2 wires, you need to buy tips with a wider plastic part - NSHV2.

Update: Removed video operation of some strippers + showed crimping pliers for sleeves:

The protective layer is available on all wires and cables. It is called insulation, it separates the conductors from the surfaces with which they are in contact, as well as from each other.

If you need to connect or install the equipment, we need stripping of wires from isolation in separate areas to ensure good contact in the contact groups.

How to perform sweeps not to damage the current-carrying veins, consider in this article.

Choosing a way to remove the insulating coating, it is necessary to take into account its features. Isolation is single plastic and multi-layered. As the latter, resins, fabrics, non-combustible dielectrics are used.

The procedure provides for the use of sharp tools. They can spoil the wire, damage isolation where it is not necessary, to narrow the cross section. Ineptly using a tool, not avoid injury.

The weakest place of wiring is the end of the cable, purified from isolation. If she lives less durable or decreases its cross section, its initial characteristics will deteriorate

To reduce all risks to a minimum, special tools have been developed, work techniques with them.

The difference between the wire and cable

When you describe the wiring, you often use the "wire" or "cable" definition as the current conductor. The uninitiated in the subtleties of the electrician man may seem like this product. In fact, they differ.

The wire in the traditional understanding is a cord with a small cross section. Such a conductor is one or stranded. He may not be insulated at all, and if there is, it is light in the form of a tube. It is easy to remove it.

The cable consists of a certain number of current media. They are connected to one whole, but do not come into contact with each other and enclosed in a shell of a special material.

The wire with one residential section sets one lived, in the multi-sized - section area forms the sum of the sections of all lived. To increase the operating properties of the cable in the middle, the Kapron thread is introduced.

With any conductor, it is accurately handled, especially with aluminum veins. Compared to copper, they are more fragile. Bending loads reduce and without that small margin of strength lived from aluminum.

Some features for comparison:

• aluminum density - 2.7, copper - 8.9 t / m;
• multi-breeding execution for aluminum is excluded for copper - possibly;
• specific resistance of aluminum 0.0294, copper - 0.0175 Ohm x mm² / m.

Damage at stripping aluminum lived additionally reduce their characteristics.

In more detail about the types of cables and wires, you can read in.

Varieties of insulating materials

Disassemble isolation single and double.

For its production use various insulation materials:

1. Plastics based on organic compounds. These are mainly thermal plastics that are softened when heated. When combustion, these plastic masses emit different toxins into the environment.
2. Termoreactive plastics. When heated becomes harder. Isolation of them applies only in special cases when the requirements for it are increased.
3. Natural or artificial rubber of different types. It solidifies when heated and supports burning.
4. Isolation based on fabric. Withstands a rather high degree of heating (maximum 400 ⁰) with preservation of insulating properties.
5. Braid shielding. This is not an insulation in the literal sense, since the braid does not act as insulation, but is protection against mechanical damage.
6. Braid booting. Also serves damage protection

The choice of tools for removing isolation depends on what material it is made.

How to clean the wires right?

In this process there are some nuances, not knowing which, you can make errors with irreversible consequences.

The cleaned area should not be outside the connection. If you leave the bare wire open, a person may accidentally touch it and suffer from electrical strike.

Isolation from the veins need to be removed from all sides. Compression of isolation residues will reduce the reliability of the attachment.

When the error is allowed in the vehicle wiring, then under the influence of vibration, as a result of attenuation, the wire will fall out of the connection

Wrong stripping will lead to a short circuit and even to ignition.

Popular Methods for Removing Isolation

Practical skills play a major role in the process of stripping the insulation of wires. The main difficulties occur when working with thin wires when the value has every movement. The optimal push force is produced only by practice.

Most often enjoy the following ways to remove insulation:

• with a knife;
• by side;
• under the influence of high temperature;
• apply stripper.

Each of the options is preferable in specific circumstances.

Option number 1 - Application of a knife for a cutting of isolation

At home, most often use a knife. Important, applying this simple tool, correctly select the slope of the blade. The biggest error is the trimming in a circle with the holding of the cutting part in the perpendicular position. In this case, it is difficult to avoid the notches of the veins or violation of secondary isolation.

The correct position of the knife is when the tool and axis of the wire are in the same plane. First cut the braid along the conductor. Next separate isolation, it is removed to the side and finally cut off at the base.

It is better to use a special electrical knife with a straight or curved to remove tight isolation from the wires. The main thing is that there are no bisps on it. If the knife is folding, it should be equipped with a retainer so that it does not develop spontaneously.

In good blades there is a double sided under a small angler, the inner rounding of the cutting edge. Some variants of the monter-knife have a special design of the blade - it is short and rounded inside, and at the end there is a "heel". It limits the depth of the cut, which is important if it is necessary to remove the upper layer of insulation without damage to the shell of individual lived.

Option number 2 - Side insulation stripping

Sideboards - the tool is convenient and safe, but only in the case of proper use. What should be paid attention to is to direct the cutting edges and the accompanying effort.

Apply the tool in two ways:

1. The shell is dropped from different sides, and after removing from the conductor. This method is suitable for working with a wire having a significant cross section.
2. The braid is fixed and cut through the cutting edges of the side, and then painted aside by making axial movements.

In any case, you need to act extremely carefully, otherwise the conductor will be either damaged or fell off.

Working with the side, you need to consider that the sharpened side of the tool sponges must be oriented towards the opposite vector of tightening the braid

We produce both windows with notches for conductors of a certain diameter. It simplifies the use of the tool at home.

Option number 3 - thermochemical method of removal

With very thin conductors, cross-section less than 0.2 mm, removal of insulation from an enamel wire or wire with polychlorvinyl insulation mechanically - a large risk. The thermochemical method is more suitable here.

In the first case, the technology is as follows:

1. The wire is comfortably laid on a flat surface. Under it is placed chlorvinyl isolation.
2. Heat the sting of the soldering iron and carefully lead them by the shell. Heating, it will fade under the influence of the released chlorine.

There is another option to remove enamel insulation from the cable. Aspirin tablet is placed on the wire, heated by a soldering iron and is distributed over the entire length. It will take place not only removal of isolation, but also prompted the wires.

Removing the braid method of melting ensures the integrity of the conductor. The method works well on the old wiring, because the winding here is characterized by hardness and lone.

Cleaning the insulation of a thin enamel conductor can be performed using fine sandpaper. Before removing the insulation layer from the wire, the sheet bends in half so that the emery is inside. In the middle there is a wire, slightly pressed with his fingers and pull. Repeat the action to complete enamel cleansing.

Option number 4 - stripping by stripper

If the insulation removal methods under consideration refer to manual, then some types of strippers allow you to mechanize this work partially. The tool is most often special ticks working with a specific wire size and cable.

Conditionally strippers are divided into categories:

• miniature manual;
• large robes;
• lever.

The first have kind of clothespins. In spring-loaded sponges, she has holes - one or more. There are small multifunctional strippers and in the form of a similar case. In the drop-down housing, holes with knives for different sections lived.

In addition, the device has a knife cutting the braid in the longitudinal direction, a knife working in the transverse direction or cutting into account. Equip them and retractable knife for stripping wires.

Next design - stripper with levers. Visually tool is similar to scissors and includes:

• Knives having a wedge-shaped cut;
• Adjusting screw, using it set the desired section.

The cable is fixed by clamps, then the levers and the insulation is removed instantly. The length of the removal is installed manually. The main minus is the need for setting in the case when removing isolation from the wires of different sections.

If you mistakenly insert a thick wire when tuning the sponges to a smaller cross section, the conductive lived occurs.

In addition to the main functions, most of these hand tools are used to crimp the tips of the multi-breeding veins, cutting off wires, cutting bolts. Sometimes they are used as simple pliers.

The tool with nests in the blades, as well as the previous one, is universal. When working with it, it is impossible to weaken attention so as not to place the current conductor into the opening inappropriate cross section.

These shortcomings are unusual for automatic lever strippers. The size of the wire here is automatically installed. The spring-loaded working element begins to act when compressing the handles. You can remove not only insulation from the vein, but also an external braid from the wires of round or flat.

Many models are equipped with a length limiter that allows you to remove the braid to the set length. The required limit is set once, and further removal occurs on the exposed limit.

Automatic models, like manual, may present an additional functionality - crimping tips, cutting and more.

Choosing a stripper model, you need to proceed from where it is planned to use. For ordinary work at home, a simple hand tool is suitable.

There is a special stripper designed to remove isolation from a television cable. Its feature in the presence of two cutting edges placed at a certain distance. It provides a convenient installation of the F-connector subsequently

When working with a mass of wires and cables, it is better to arm a semi-automatic or automatic device. This tool is needed by professional electrical installation.

On our site there is an article where we told in detail about the stripper to remove insulation from the wires. Go to to familiarize yourself with the material.

New tools for deleting isolation

Relatively recently the range has replenished four new products:

• plug knife for removal of hard insulation;
• stripper for cutting isolation 2.9 - 6.6 mm² in the longitudinal direction;
• tool for working with wire insulation 0.05 - 2.5 mm²;
• tool for cutting wire insulation 0.25 - 6 mm².

All of them released by the United States Jonard Tools.

The new stripper of case type is equipped with five grooves with a diameter of 2.9 - 6.8 mm. Blades are available both from above and below. Cuts longitudinally wires, optical modules, protective tubes.

The plow knife is used when it is necessary to remove the braid cable from rubber, PVC, PE. A knife with a two-way blade performs cuts of longitudinal and transverse depths of up to 5 mm

The stripper for removing the insulating PVC layer with cables with a diameter of 0.05 - 2.5 mm² is automatically adjusted to the desired section. With pressure on the handle, the conductor is captured, the blades are insulated and tightened it.

The last model is similar to the previous one, but works with the wires of other sections.

There are non-standard situations, of which it is difficult to exit even a specialist. At the same time, you have to take creative solutions and use sweater tools. Consider a couple of examples.

Example number 1 - damage to the wires leading to the fork

The method is used if the visual inspection found that the charging device is defective thin wires leading to the fork. The main complexity of the situation is not only in a small section, but also in the strain cable. It is also problematic that the wires are enclosed in a solid braid, so the insulation is not just a protection, but two or three-chamber collector.

In this case, in this case, it isolating quickly, experts use a thin blade from the cassette from the razor. The cable is fixed by clamp from a desktop lamp or vice. The cable is separated on the veins, the blade neatly make an incision in the right place is not too deep. Next, the part of the layer is approaching the nail and carefully remove.

The protective layer may be in the form of a rigid outer insulation, the inner fuel layer, fabric, impregnated with resins of insulation, individual insulation of each vein

First, using the tool is get rid of the outer shell by cutting it along the cable. Then, by means of the pliers, the veins take out. The remaining insulating layer is simply cut.

The work associated with electrical current is not easy. Therefore, even possessing certain knowledge, you must not forget that damaged lived over time will be conveyed.

For security reasons when removing isolation into a slightly large, the length, excess must be cut off. Tarlers are too dangerous.

The home master is inappropriate to acquire expensive tools in order to take advantage of them several times, removing isolation. In most cases, simple remedies are quite suitable.

It is not always advisable to remove isolation if the cable consists of thin lived. You can, without removing the insulating layer, disconnect the veins, and to create a contact to use a special clamp with teeth

Contact If the piercing clamp is installed, provides an insulation puncture. Sometimes this is enough.
