( Industry news] The appearance of the wire and cable products are basic requirements SXXLJT P ( ) Round aluminum rod for check whether there is the degree of roundness, ruffled, wrong circle, defects such as cracks, inclusions, kink and severe mechanical damage scabbing, hemp pit corrosion, peeling, flash, spots, etc. ( ) Round copper wire to check whether the surface is bright and clean, and presence of triangle, crack, burr, folding and inclusions and serious scabbing, hemp pit, mechanical damage of corrosion spots, and so on and so forth. Is worth questioning and copper oxide, generally golden color is normal, reddish for mild oxidation, surface for severe oxidation when dark red, blue, who shall be awarded to severe oxidation of waste treatment. Aluminium wire line condition is more, in the process of manufacturing for overhead transmission line should be kept under strict control. ( ) Aluminum is wire surface compactness and regularity of wires shall be stranded wire and cable products, there can be no loose, kink of single, single out or protuberance and single fracture phenomenon, etc. . In addition, the single joint welds should be rounded and welding has been asked to do the anti-corrosion treatment, increase the joint parts must not be more than twice the diameter tolerance in general, two single joint welds span length also want to accord with a standard, the same single wire welding place should not be less than two meters, the same layer of the same two welding wires is the layer of the spacing of not less than m, the outer layer is not less than m, copper core of single copper wire, welding is not permitted.
