At present, there are many kinds of wires and cables in the market. Whether for household or enterprise use, it is necessary to distinguish the authenticity of many national standard or non national standard cables and wires. Only the authentic ones can greatly reduce the possibility of danger in the subsequent use process. How to judge the authenticity of a wire?

The cable manufacturer believes that the authenticity of a wire or cable can be judged from the following aspects:

1. If the head of a power cable wire is constantly bent, it can be considered as genuine if it is relatively soft, and the plastic, rubber, etc. of the skin protective layer have good ductility without cracks.

2. Check whether the power cable is genuine, mainly the copper. Generally, the copper core of qualified cables and wires is purple, shiny and soft. The copper core of low-quality cables and wires is mostly purple black, some of which are yellow or even white, with many impurities, low purity of copper, poor flexibility, and may be broken with a little effort. During the inspection, the copper core is exposed and slightly rubbed on the white paper. If there is black substance, the quality of the cable and wire is not very good.

3. To know whether a cable or wire is genuine, we can see whether there is a certificate certified by the quality management system, and whether there is a certificate of conformity and a unique trademark logo.

In addition to judging whether the power cable is genuine through the above points, the quotation of cables and wires with the same weight can also be used as the most basic judgment basis. Generally, the cost of fake and shoddy wires is relatively low, and the selling price is lower than that of genuine ones. In addition, the weight of genuine cables and wires of the same length will be slightly heavier than that of counterfeit or even defective ones.
