There's one thing the electrician industry needs: insulation tape, which we can also call insulation tape. It not only does that, but it also has a very good viscosity, so he is very popular in electrical insulation protection.

We have to master how it works. The power lines are getting more and more complicated. There are power lines under some floors, as well as partitions, or wet underground. If we don't use it correctly, there is a danger of leakage. This will endanger our personal safety, so we must know how to use it.

When the joint is made, it should be wound firmly and smooth. There is no Burr. Before the line head is disconnected, use a wire clamp to gently press it and then wrap it around the pressure port. If the joint is in a dry place, Then you should wrap two layers of insulated black tape and then wrap plastic tape. This can greatly avoid causing safety hazards.
