| description | The invention provides a method for stably producing high-quality wires and cables so as to overcome the defects in the prior art. The method comprises the following steps that S1, 2.50 mm-3.50mm copper wires are drawn into the 0.40mm-1.60mm copper wires, the tension detection and control are carried out in a wire drawing process, and meanwhile, the annealing treatment is carried out; S2, more than two copper wires are twisted to obtain a wire set; and S3, the wire set is extruded and coated by adopting a first formula to obtain single-core cables wrapped by an insulating layer. The first formula in step S1 comprises the following components of, in parts by mass, 3-5 parts of cross-linking agent, 12-15 parts of phenyl silicone oil, 3-5 parts of allyl thiourea, 20-40 parts of nano magnesiumhydroxide, and 100-120 parts of ethylene-vinyl acetate copolymer. The method disclosed by the invention has the advantages that the problems of non-uniform wire drawing and overhigh internal stress are avoided, the flame ret |
