In life, we often encounter electrical wiring. This can be a wiring in the room, and a power cord from the TV.Nothing in this world lasts forever, and any wire can be damaged. Damage can be mechanical, thermal, and whatever. But the result is always the same - damage to the outer insulation layer. And the question arises - how to insulate the damaged place of the wire. And no less important - how to do it correctly, which means more, and what to isolate? It often happens that two wires are spliced, which means that the connection point also needs to be isolated.
Connection point for
wires Firstly, , you need to connect the wires correctly - this is done in twist. If the wires are multi-stranded, even one of them, it is best to spin it into separate wiring and twist "in parts", so twisting will be more reliable. The received connection for reliability, if possible, should be disappeared. After that, twist should be cut lengthwise, leaving the end about 0.5 cm. This tip should be bent close to the wire.
Secondly, can be used as the first layer of insulation using a heat shrink tube, and ordinary PVC can be used. In the first case, the tube is pulled into the hot spot of the spike. It is worth considering that after cooling down, this isolation will not be possible to remove. In the second case it is necessary to wait, when the spike will cool down, and then on a twist to plant a piece of a tube of PVC.
Isolate the damaged wire location
- If we have already found the damage in the wiring, you can snack the damaged wire and then make a reliable twist;
- If the place is at the end of the wire, then if there is a tube, the wire is disconnected, the tube is inserted;
- Insulation is made of electrical tape. Better - in two layers, with a "reserve".
It should be noted that if the wiring is on the street or in a room with a low temperature, then it is better to use a tape with a fabric backing. The PVC tape is cracking at low temperatures.
