The cable has entered the life around us. The material and function of each cable are also different. So how do we distinguish the advantages and disadvantages of the cable? Today, our small series of Kunshan copper wire first introduces how to distinguish the advantages and disadvantages of copper wire and cable.

First of all, I want to say that the general quality copper wire and cable are relatively soft, and the plastic on the surface is elastic. If we repeatedly bend the copper wire and cable by hand, there will be no corresponding insulation on the insulator. Cracking phenomenon. Moreover, the plastic skin of the insulating layer is bright and radiant, and there is no open flame in the ignition. Another way is to see if the copper core is in the middle of the insulation. Because if it is not centered, when there is a large current, it is possible to wear the thin side. Therefore, the copper wire and cable that is not centered on the copper core is a poor quality cable. The third method depends on whether the specifications are formal. In the relevant regulations, the length of the copper wire and cable cable shall not exceed 5%, and the cross-sectional diameter shall not exceed 0.02%. If you do not meet the requirements at the time of purchase, then do not purchase it. When we can check according to the above three points when purchasing, we should be able to buy high quality copper wire and cable.
