Wire and cable products are closely related to people's lives, so its quality and safety directly affect people's personal and property safety, so it is very important to choose the right cable.

      The appearance requirements of our team's wire and cable are very high, and they need to have a smooth and round appearance and uniform color; the appearance of counterfeit and inferior products is rough and dull. The specific requirements are as follows:

      1. Round copper wire to check whether the surface is smooth, with or without triangular mouth, burrs, cracks, folding and inclusions, and severe spots, pits, and corrosion spots of mechanical damage. There are many roads in the manufacturing process of aluminum wire, and should be strictly controlled when making overhead transmission lines.

      2, round aluminum rods require inspection of the degree of roundness, whether there are folding, wrong round, cracks, inclusions, kinks and other defects and serious mechanical damage, plaque, pits, peeling, flashing, corrosion spots.

      3. The surface wire of the aluminum stranded wire should be twisted and tightly packed, and there should be no looseness, single-wire kink, single-line jump or bump and single wire breakage. In addition, the joint welding of the single wire should be rounded and the welding has been required to be treated with anti-corrosion treatment. The enlarged part of the joint is generally not allowed to exceed twice the diameter tolerance. The length of the joint between the two joints of the single-wire joint should also meet the standard. The copper core is Welding is not allowed when a single copper wire is used.
