Stripping tool ws 04
Usually the plastic insulation is stripped mechanically (with a knife or side cutters) or by melting. The enamel insulation is stripped mechanically (by scraping with a knife or sandpaper) or chemically.
How to Properly Strip a Wire with a Knife
It is wrong when to remove the insulation it is cut in a circle by the blade of the knife, oriented perpendicular to the wire while applying more force.
This cuts the copper wire and the wire can easily break at this point. This is especially important when stripping thin wires, with a diameter of 0.6-0.8 mm. They break after such stripping after a few minor bends.
The blade should be in approximately the same plane as the wire axis. The insulation is cut along the conductor and the remainder is taken off to the side of the wire and also cut.
How to properly remove the wire with a pair of wire cutters
The second mistake is often made when stripping with side cutters. Usually pick up the tool as you need it, not paying attention to the orientation of the cutting edges.
If the sharpening side is in the direction of the side cutter movement, a significant clamping force has to be applied. The wire can easily break off with the insulation.
You want the cutters cutting edges to face the opposite side of the wire, as shown in the photo. As a result, even a light touch on the insulation causes the cutting edges to cut into the insulation and the insulation can easily be removed with a tube without notching the wire.
Removing Plastic Insulation by Melting
Insulation of modern wires for electric wiring is usually made of PVC or polyethylene, the melting temperature of which is in the range of 105-140C. So you can easily and safely strip the insulation off the wire with a soldering iron or other heating device. You only have to use the tip of the soldering iron tip to press on the insulation circumference in the right place. The insulation heats up, melts, and is easily removed by hand.
As you can see, the insulation came off perfectly without harming the copper conductor.
The method of stripping insulation by melting is indispensable when working with old electrical wiring. Over time, the plastic ages and becomes very stiff, like a bone. A piece of wire only 3 cm long goes into the junction box in the wall. You can’t get at the insulation with a knife or wire cutters. In this situation, only melting can solve the problem. To soften the insulation you can warm it up with a match or a gas lighter and then take it off.
Removing the Enameled Wire Insulation
If the diameter of the wire is more than 0,2 mm the most convenient way is the mechanical method of stripping the insulation with the help of sandpaper or scraping the enamel with the knife.
To remove with sandpaper, bend a small sheet of fine sandpaper in half, put the end of the wire inside between the bent halves of the sheet and pull the wire through without squeezing too hard with your fingers. Repeat the operation by turning the wire until all the enamel is stripped.
To remove enamel with a knife, you should put the end of the wire on any hard surface and by turning the wire in a circle scrape off the enamel until the end of the wire is completely clear of varnish.
In the case of stripping wires with a diameter of less than 0.2 mm, it is difficult to remove the enamel mechanically without damaging or breaking the conductor.
But it’s easy to remove the enamel with a thermochemical method, using a soldering iron and a piece of chlorvinyl insulation. To do this, pull the end of the wire between the sting of the soldering iron pressed against the chloro-vinyl. The chlorine released from the heat will clean the wire from the enamel.
This method is indispensable for removing enamel from licorrat type wire, which is widely used in radio communications for winding high-frequency inductance coils. Licker wire is a lot of thin wires covered with enamel and twisted into one conductor.
Aspirin can also be used to remove the enamel, you put the wire on the pill and press it down with the soldering iron, and then pull the wire through. In this case the wire is immediately and wire-wound.
Removing the PTFE insulation
Fluoroplastic is a polymer produced chemically that is resistant to organic solvents and is not wetted by water. Characterized by high electrical strength, resistant to temperatures up to 300°C. Ideal insulating material, but expensive. Therefore, it is only used in technically justified cases. Household fluoroplastic wire is used by radio amateurs, as it does not melt when soldering with a soldering iron, takes up little space and has an aesthetic appearance.
Fluoroplastic insulation is a thin, narrow strip wrapped tightly around a strand of fine, stranded copper wire. To free such a wire from the insulation can only be physically.
This is best accomplished with a knife. Pressing the wire to the pad, the fluoroplastic is scraped off with a knife to the required length.
After the wire is exposed, it is bent aside and the remaining fluoroplastic is cut off. The result is a neatly stripped of PTFE insulation wire ready for soldering.
Insulation made of rubber, cloth and other insulating materials can be removed by one of the mechanical methods described above. The main rule is to avoid notches on the wire strands.

This is the most popular modification of everyone’s favorite stripper WS-04. The main difference of the new model is the special window through which the stripped insulation falls out. The WS-04 had no such opening, and the stripped insulation had to be simply shaken out of the tool, which was not very convenient and took too much time. No such problem with the new WS-07 stripper.
If you’re worried about the result, you’d better crimp the lugs not with stripping tools but with special crimping pliers, designed for this purpose. But, as a last resort, if there is a strong need to press an ending, these profiles can also be used. They are designed for different types of lugs, depending on the stripper’s model. insulated, bushing, copper of small cross-sections, auto-terminals, a number of specific connectors. But a good result with them will not be achieved.
This problem occurs most often when using low-quality wire. If you look at the wire from the end, the current carrying core should be centered in the insulation. If it is, as is often the case, offset to the side, it is more likely to be damaged when stripping with hand strippers. In that case, it’s best to use automatic tool models, or try a nearby larger Caliber.

Strip flat two- and three-core wires such as PPV, VVG-P, PUNP small cross-sections (up to 2.5 mm2 maximum), telephone wires and the like can be the following models strippers: WS-04A and B, WS-07, WS-11, WS-12, WS-14, WS-15 and WS-17. Note, however, that these tools do not strip all flat wires (depending on the material and thickness of the sheath), so it is better to test before buying a stripper.
It is not advisable to strip or cut live wire with any tool at all. The line should be de-energized before any work, but if this is necessary, or if there is no guarantee that no one will energize the line while you are working on it, then you should only use a special insulated tool that allows you to work on live lines up to 1000 V.

These tools are most often imported. And in most countries, wire cross-sections are denoted by the American AWG standard, which is not at all related to cross-sections in mm² in the principle of designation. For example, a cross-section of 0.5 mm² according to the AWG standard is indicated as 20. The bigger the number, the smaller the wire cross-section. For more information, refer to. Cable cross-section conversion table from AWG to SI system.
