Today we introduce how to distinguish the pros and cons of copper wire cable.

First of all, the general high quality copper wire and cables are relatively soft, the plastic surface is elastic, if we use our hands on the copper wire wires and cables by repeated bending, the insulation will not appear corresponding cracking phenomenon. Moreover, the plastic skin of its insulation layer is bright and shiny, and there will be no open fire when lit. Another method is to see whether the copper core is in the middle of the insulation layer. Because if it is not centered, when a high current passes through, it is possible to penetrate the thin side. Therefore, the copper wire core is not in the copper wire cable is inferior cable. The third kind of method is about to see its specification is normal. In the relevant provisions, the error of the length of copper wire and cable cannot exceed 5%, and the cross section diameter cannot exceed 0.02%. If you don't meet the rules when you buy, don't buy. When we can check according to the above three points when buying, we should be able to buy high-quality copper wire cable.

Copper wire bending is the surface of copper material bamboo or copper surface with hiss fixed pitch torsion, feel the surface of copper material lubrication, not straight phenomenon commonly known as small bending; The phenomenon of line knotting caused by line looping is commonly known as big bending; The two phenomena are collectively known as bending.

Causes and avoidance measures:

1, the tension is unstable, large fluctuation: report to the equipment department maintenance, adjust the tension spring, adjust the tension counterweight block.

2, die and line are not the same axis horizontal blind bow, resulting in wire line is not straight: adjust the position of the die frame.

3. The sizing area of the mold is too short or the matching mold is too loose: adjust the mold.

4, wire drawing machine vibration: report to the equipment department for maintenance.

5, regulating wheel groove, series or not flexible: frequent inspection, regular replacement.

6. Wire binding head of cruise wheel: stop for adjustment.
