Principle of stripping wires of insulation

Professional tools use two principles to remove the protective coating from the cable:

  • Tearing. This method can be compared to wire stripping with teeth, where a piece of insulation sandwiched between the teeth is torn away from the rest of the covering with a force directed along the conductor.
  • Cutting. In this case, the cutting edge cuts through the protective layer in a circle, without damaging the current-carrying conductor. Then, part of the cut tube is removed from the conductor with a little force.

Professional tools for stripping wire insulation, there are:

For working with small amounts of wires at home, you can use simple ways to strip their ends.

Easy ways to strip wires

The stripping of cable ends can be done in two ways:

  • By applying heat. This method heats the strand to the melting point of the insulation. It is carried out:
  • Soldering the PCB insulation layer with a soldering iron and then removing the coating with pliers. The big disadvantage is the presence of toxic fumes and corrosion on the soldering iron tip.
  • Use a lighter at.
  • Using a heated nichrome wire.

These techniques are best used for thin, low-power conductors used in electronics, communications devices, audio equipment with stranded soft conductors operating in circuits where the voltage is about 5 volts.

Tip: These methods should only be used when stripping a small amount of wire on a one-time basis.

  • Mechanical shear. The method is based on removing the protective layer with the cutting edges of the tool. At home, a wire stripper is best for this purpose.

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

  • Use a metal saw blade with a small cutter blade.
  • It is sharpened on an emery machine to give the tool the shape of a sharp, thin wedge.
  • The handle is made by tightly wrapping wire with several layers of electrical tape.

This blade cuts off a layer of PVC perfectly, but mishandling the blade easily damages copper or aluminum metal close to the insulation.

Tip: When using such a homemade tool, the blade sharpening plane should be very carefully directed at an acute angle to the layer of insulation to be cut, which will allow the tool to slide over the metal wire when it touches it, rather than cut into it.

How to quickly strip copper wire insulation at home, suggests the video.

Why do you need a wire stripper?

In addition to the basic characteristics of professional tools, users estimate by how much the speed of work and its quality increases when using them.

Even if you change the wiring of a typical apartment, in each of the rooms (living room, kitchen, hallway, etc.д.) will be at least one light bulb, one switch and a few outlets, plus contacts in the input panel. Two or more wires go to each of these points, so their total number will be up to several hundred.

If a modern repair is done in a large area, in which in addition to lighting and power wiring are laid cables for the Internet, television, sound systems, and others, the number of contacts for which you need to strip wires, easily exceeds a thousand pieces.

Often wires need to be stripped to a certain length, for example, this is required when installing some brand-name sockets. otherwise the core will simply not fit in the socket designed for it. Most pliers have the ability to adjust the length of wire to be stripped, but with a knife, you’ll have to rely on eyeballing.

Even if you lightly snag a wire strand with a knife blade, such a conductor has increased sensitivity to kinks, and the place itself with a scratch can begin to heat up. The wire stripper, on the other hand, is made to cut the edge of the sheath without touching the wire.

As a result, most customers may be suspicious of an electrician who doesn’t have a wire stripper among his tools.

Insulation Removal Tool.Views and Operation.Use, choose

Special tools are used to quickly and easily strip wires and cables. An ordinary knife, side cutters, and soldering iron can be used to strip the conductors, but this method is time-consuming and cautious, especially when the conductor consists of thin twisted strands of copper. Aluminium strands are the most sensitive to bends, cuts and scratches, and must be treated with care when removing the PVC sheathing. In order not to disturb the mechanical condition of the metal strand, it is recommended to use a specially designed tool for stripping the insulation.

Choosing stripping method for different wires

The amount of stripping effort depends greatly on the type of wire. When selecting a tool, the specifics of the cable should be considered:

  • Coaxial wire. Double stripping involves two steps. Upper layer can be removed with a thermal method and the lower layer with a stripper. The strands of such a cable are very brittle and thin, so they are easy to damage.
  • PTFE-coated cable. Heat-resistant insulation that can only be removed mechanically. An electrician’s knife or wire stripper will work.
  • Enameled wire. If it is under 0.2 kV. If you want to use the thermo-chemical method with a soldering iron and chlorvinyl tape, then you have to resort to the thermo-chemical method. The wire is placed on the tape, run the soldering iron over the cable. the chlorine released promotes the “detachment” of the enameled sheath from the wire.

When choosing a tool, one should take into account for which diameter of wire the device is designed, as well as the handle material.

If electrical cables have to be stripped, strippers with a handle of dielectric material are to be chosen.

Coating protects from voltage within 1000 watts.

What kind of stripping tool is used?

Cable stripping tools can be classified according to the stripping method, scope of work, and automation of the process. Domestic and professional tools are differentiated according to the scope of work. The first group includes the electrician’s knife. Professional equipment includes pliers, pliers, strippers and pullers.

Pliers, pliers, strippers and pullers are professional tools for working with electrical wiring

Important! The tool for electrical wiring work can be universal or specific, which is determined by the diameter of the wire being stripped.

To remove the insulation sheathing, you can do it mechanically and thermally. The latter option is used for low-power thin conductors, which are used in communication devices, electronics and audio equipment operating on 5 V. Heat can be used to clean a small number of wires on a one-time basis. To heat the sheathing use a blowtorch, a lighter or a heated chrome floss.

Important! If liquid wire insulation has been used, it can only be removed mechanically.

Professional methods include mechanical stripping. The process can be based on cutting or tearing the sheathing. In the first case, the insulation layer is cut through in a circle with a point, after which the current-carrying cores remain undamaged. Part of the cut surface is removed from the wire. Stripping method involves clamping the insulation and tearing it off (by force) the conductor.

Depending on the diameter of the wire to be stripped, the stripping tool can be a universal or a special purpose tool

Stripping techniques

Wire cutting can be done in two ways:

First version is used for solid and stranded conductors with low voltage (e.g. MSTF), a soldering iron or other thermal tool up to a lighter or match can be used for this purpose.

Mechanical method involves removing the insulation sheath from the cable with a special tool, which has cutting edges. This type should be considered in more detail.

Tools

Quite often the insulation is cut with a knife, but as we’ve already reviewed above, damage to the wire in such a case significantly reduces its performance. Even with careful handling, scratching the wire is almost guaranteed.

Pliers, pliers, side cutters also cause damage, an experienced craftsman, using such a tool, will still allow a few defects in a certain number of operations. Even an electrician’s knife with a specific sharpening does not guarantee that the wire will not be damaged.

Specifics of sharpening

Professional tool

To avoid the above described problem connected with wire damage at stripping it is necessary to buy a stripper such as: WS 07, WS 04A, CS: GO 25, Jok 828 or to pay attention to the model range of companies Khipex (Knipex), AMD, Jokari, Wirefox, Weidmuller, etc.д.

Tools for professional use

The design and principle of operation of such tools are as follows:

  • two movable half blades, the cutting edge of which corresponds to the cross section of the wire (that is, each blade has a sharpening for a certain cross section), when squeezed, cut the insulation. The wire itself is not damaged;
  • And then the tool moves along the wire, stripping the insulation.

As a rule, almost all the strippers are universal, that is, they can cut cables of different diameters and perform additional functions, for example, be used for crimping lugs.

Depending on the purpose and design these devices can be:

The hand-held tool refers to the simplest designs. Its blades are designed to remove paper, rubber, and other insulation from wires of a certain cross section, which is actually enough for a household tool. Optionally, they can be adapted for cutting coaxial or twisted pair wire. Such as the Zubr model from Stayer.

Universal model from the company Stayer

The semi-automatic tool is more versatile. it allows you to adjust the working area of the cutting surface. That is, a certain stripping length can be set (Duro-Stripax, Stripax Pro, Proskit, etc.).д.). In domestic use, this function is not principal, but in professional use such a tool is simply indispensable.

The model from the company Weicon

Now let’s take a look at an automatic professional tool. The price for such equipment inspires respect, but it is explained by its versatility. As a rule, automatic strippers allow the following:

  • set the working area for stripping cable insulation from a certain wire cross-section with the required length. The instruction to such a tool is very precise describes how to make adjustments, deviations from it will produce the opposite effect, that is, damage the wire;
  • to do crimping of lugs;
  • to do the pruning;
  • strand stranded wires. Note that with a cross section of more than 5 mm it is quite difficult to do it with ordinary pliers.

These models also allow you to simultaneously work all the wires of the cable, rather than one of them, which is quite practical. And the adjustable stop allows you to brush them to a certain length.

example of use with the WS 04B wire stripper

As a rule, such equipment is designed for cross-sections in the range of 0.5-25 mm 2. For example, HT-8, WS-8, HS-5, PK-10, CP-10, AM-25, etc.д., note that the numbers indicate the maximum size of electrical wires that the tool can work with.

For cables with thicker cores other equipment is available, we will talk about it later.

Many universal strippers can be used for fiber optic sheathing. For optics it is better to buy a set of tools (Neo, LWL,NYM, etc.).д.), which includes everything you need for cutting, chipping and shearing.

Note that for class MB optical cables (armored, can be installed inside the pipeline) a plough-type blade (e.g. KMS-K) is needed, as well as shears for cutting kevlar (KBT, Haupa, GB-M, etc).д.).

Machines

To make the job easier when cutting thick cables or stripping large quantities of cable, special machines are used. The cutting part of this equipment consists of two circular blocks with a concave profile.

The upper clamping block has a built-in knife, which cuts the outer sheath on power multicore cables, the second block (lower). the thrust one. When the motor turns on, it turns the upper block to push the cable through and cut the insulation.

Stripping with a machine

Selection Criteria

Externally, this small machine resembles pliers, but in the inner part of the clamps there are several holes of different sizes with blades on the edges. This makes it possible to work on any size of material. The best models have sockets in the body with a marked size so that it is easy to remove the insulation from the wire. The edges of the cable are perfect.

After a short push, the mechanism will close the semi-circular blades, cutting the insulation material across. Review of popular models showed that some of them are equipped with mechanisms that independently detect and adjust to the cross section of the cable. A limiter will prevent snagging a neighboring area. You can also find the device, which is equipped with legs with wedge-shaped notches that allow you to adjust to the diameter of the cable by adjusting the screw. What aspects to look for when selecting the pliers?

CharacteristicsDescription
Shape The main problem in selecting a fixture, which often leads to errors, is the abundance of shapes that mislead the purchaser. The device can be made as a pair of pliers with straight type jaws, or the working surface will have a curved shape and an end type grip. However, they can be used to reach the most inaccessible areas. Also, Russian-made products may have special holes with blades that are located on the side.
Material Depending on the type of tool used, different raw materials may be used. Tool steel is used for the manufacture of lever structures, in which the handles are coated by manufacturers with a special insulating plastic. There are also rubberized inserts based on fiberglass and polyamide. You can also find models equipped with metal blades and a plastic body. This is the variant that is better to buy for home use.
Medium depth and sectional range Each tool will work within the cross-sectional range designated by the manufacturer. A set designed for 0.2-0.5 mm or 6-10 mm is considered standard. A 0.02-0.2 mm stripper is used for micro ranges. In most cases, there is also a special limiter. As such serves a plastic or metal element. It is used to secure the wire in the designated position. In this way, a person will not be able to insert the wire deeper than possible. Can be adjusted. This is an extremely useful option for those who are used to performing monotonous manipulations every day.
Weight and size The tool is 14-22 cm long and 1-3 cm wide. The height reaches a mark of 6-13 cm. The weight of the product will be 50-450 g.

Attention is drawn to the fact that not every stripper can be used with cords that are energized. Such manipulations should be carried out only by automatic products with a special marking “electrically insulated”.
