For example, the commonly used plastic insulated single-strand copper core wire with a cross-sectional area of . Poor quality wires have insufficient weight, are either not long enough, or have too many impurities in the copper core of the wire.

It will break with a little force, and there are often disconnections in the wires. . During the inspection, you only need to peel off one end of the wire, and then rub it on the copper core with a piece of white paper. If there is black substance on the white paper, it means there are more impurities in the copper core, and it can be regarded as a non-standard wire. cable.
