How To Tell The Difference Between The Quality Of Bare Copper Wire

Bare copper wire due to the content of copper and the equipment and technology of each production and processing plant is different, resulting in the quality of bare copper wire is also very different, today bare copper wire manufacturers will teach you a few tricks to distinguish good and bad bare copper wire methods.
First, the toughness of good bare copper wire is very good. Take out a steel wire and bend it several times, if it is easily broken, it means that the quality of this steel wire is not very good. There is also a thin layer of plastic skin on the surface of the bare copper wire, and there will be no open flame on the surface after the good bare copper wire is ignited.
Second, look at the wire core. If the core is in the center of the cable, the quality of the bare copper wire is better. If it is not in the center, then it is easy to have a breakdown accident when the electricity consumption is too large.
Third, when purchasing, pay attention to check the length error of the bare copper wire and the error of the diameter of the cross-sectional line. This is very important, the general length error is greater than 5%, indicating that the line must have been passive.
