Which tool to use?

knife electrician

The easiest way to remove the insulation from the wires using a standard knife.In this case, the upper protective layer is removed by longitudinal incisions, and she contacts the shell incision around, plunging the blade a little inside.In this case, you do not spend much time on this activity, but there is a risk of damage to the conductor, especially if thin coils.

If you decided to use a knife, it is advisable to use a special blade is slightly curved for easy cleaning of the implementation.Note the handle it must necessarily be made of a material which does not conduct current.

Experienced electricians are advised to remove the insulation of the wires with a knife on the following technologies:

1. conductor puts on the table.
2. presses the index finger of the left hand (if you're right handed).
3. other hand take a stripping tool (in this case a knife) and slightly pressed into the protective shell.
4. index finger of his left hand slowly scroll through the material one full turn (very handy if you decide to remove the skin with a circular power cable).
5. pulls together a cut piece of insulating material (can be PVC, rubber, silicone and even paper wrapper).

That's the essence of the work.As you can see, nothing complicated, but there is a high probability of damage to the contact, making this method is not very effective.

Soldering

second way to remove the insulation from the wire and power cable - to use a soldering iron.In this case the sting is heated to the desired temperature, after which you are similar to the previous version shooting shell (Explorer finger scroll, leaning against the soldering iron to the insulation).As a result, an extra piece of the shell is easily separated from the rest.The disadvantage of this method is that the unpleasant smell would go on contact material with the heated tip on the premises.In addition, a soldering iron is not recommended, if the shell is rubber.

way similar method can be used and another tool - the so-called "obzhigalku".When using it, you will hear all the same unpleasant odor, so it should be used only in extreme cases.

Remover

There are also versatile tools for stripping wires and cables, referred to as manual Strippers.Such products Bole functional becauseallow to manually adjust the diameter of the living, so that when pruning not to damage them.Use Strippers quite simple - commit to the desired contact and scroll through the guide direction by one turn (as shown in photo).

In the market there are also special strippers to remove the insulation XLPE without burning it.Such tools are expensive (more than 6000 rubles) and used for industrial purposes, so their review, we will not go into details.

2. To clean insulation enameled wire, it is recommended to use a knife or soldering iron.The first option is suitable in the case of over 0.2 conductor section mm.kv.In that case the core is thinner, it is necessary to use soldering to remove enamel coating.You can also gently remove the enamel with sandpaper, scraping her forth motions.
3. rubber coating is best to remove the special tool to remove the insulation from the wires.As we have said, a soldering iron and obzhigalka are irrelevant.
