3 tips to distinguish the quality of copper wire

In recent years, with the copper wire into all walks of life, relatively speaking, it is gradually replacing aluminum wire as a new generation of cable material, why now cable factories choose copper wire as material? That's because the performance of copper wire determines its advantage. Want to know how to identify the pros and cons of copper wire? Then you will listen to dongguan nickel-plated copper wire manufacturers to elaborate for you about distinguishing the advantages and disadvantages of the copper wire method.

1, we can take a copper wire head repeatedly bending by hand, with soft feel, good fatigue strength, plastic or rubber feel elastic and no cracking on the copper wire insulator is what we usually say is superior. The outer plastic skin of copper wire should be bright in color and fine in texture, and there should be no flame when lit with a lighter.

2. We cut off a section of insulation layer and then see if the core is in the middle of the insulation layer. If not in the process is not high and caused by the phenomenon of eccentricity. So while we can get away with using low power, the thinner side is more likely to be penetrated by the current once we use a lot of power.

3, in the purchase of copper wire, we must see the length and core thickness has been rigged. In the relevant standards, the error of copper wire length cannot exceed 5%, and the cross section diameter cannot exceed 0.02%, but there are a lot of short-weight on the length and fraud on the cross section in the market.

The above 3 points are the methods we often use to distinguish the quality of copper wire, of course, there are other methods can also be judged, here is not clear, if you want to buy copper wire products, welcome to give priority to our Huashi metal, the quality and price are satisfactory to you.
