The cable should be twisted closely and tidy and should not appear broken strand, lacking of strand, loosing strand and overlapped phenomena. But if the surface of cable exists in local light mechanical damage, etc defect, it can also be recognized as salable product.
Single wire permits to weld. The welded place of each single wire should be smooth and round. The tensile strength at welded place for hard aluminum should not be less than 7.5 kgf/mm²and for steel wire electroplated zinc should not be less than 80 kgf/mm².
The make length of cable is not less than 250mm, shortage length more than 20m may be delivered before particularly case. Delivered special requirement to be discussed between both side.
