What are the hazards of using inferior wires and cables? How can you tell if it's a low-quality cable?

At present, the wire and cable industry in the market is also quite chaotic. According to the editor, many cable companies in the market have the phenomenon of cutting corners, and the cutting corners are precisely the heart of the cable - the copper core. According to statistics from the fire department, in recent years, almost half of the causes of household fires are caused by electrical failures, and the lack or poor quality of the copper core is also one of the main reasons for wire fires. So it can be seen how important it is to choose legitimate wires and cables.
Firstly, when looking at the label, the handwriting on the surface of inferior cables is not clear due to their rough workmanship, and there may even be some typos. If you scratch them with your hand, you can even erase the handwriting. Therefore, it is important to pay attention to cables with these characteristics.
Secondly, take a look at the insulation layer. The outer skin of the insulation layer of inferior cables will fade, and the handwriting on the insulation layer can even be rubbed off by hand. In addition to rubbing off the handwriting on the insulation layer, using a nail to scratch the insulation layer will reveal a clear mark that can even be scratched open. This is also a poor quality cable, and there is also a way to fold the insulation layer. The insulation layer of a poor quality cable will break when repeatedly folded.
Finally, looking at the copper core, the color of the copper core of inferior cables is gray and has no metallic luster. Even some low-quality cables have black or purple copper cores. We hope everyone should pay attention when choosing!
