Due to the copper content of the Kunshan copper wire and the different process conditions of the various processing plants, the quality of the copper wire is also very different. Today, the copper wire manufacturer teaches you how to identify good or bad copper wire.

First, the toughness of a good copper wire is very good. Take out a wire and bend it a few times. If it is easily broken, it means that the quality of the wire is not very good. There is also a thin layer of plastic skin on the surface of the copper wire. After the high-quality copper wire is ignited, there is no open flame on the surface.

Second, look at the core. If the core is in the center of the cable, the quality of the copper wire is better. If it is not in the center, it is easy to have a breakdown accident when the power consumption is too large.

Third, it is necessary to check the length error of the copper wire and the error of the section line diameter when purchasing. This is very important, the general length error is greater than 5%, indicating that the line must be passive.
