Cables and wires are crucial in our daily work and living environments. Poor quality wires can directly affect circuit stability, posing significant safety hazards to everyday electricity use. To achieve higher standards of wire and cable quality, one must master some identification methods. By understanding these methods, unnecessary impacts and risks can be naturally avoided. Let's delve into this in detail next.

One: Identification method for conductor wire: It is impossible to distinguish from appearance. However, it is lighter in weight than the national standard wire. There is also a simple method, which is to cut it open from the middle on the spot and measure it actually.

In terms of conductor material identification: Copper-clad aluminum wires are mostly made of soft copper wire. The identification method is quite simple. Light the flame of a lighter and burn the end of the copper wire. Since aluminum has a lower melting point than copper, if it's copper-clad aluminum, the burned part will quickly turn into ash, leaving nothing behind. On the other hand, with pure copper, the wire will rapidly shrink back after burning, leaving a small ball at the tip throughout the shrinking process.
