What is the difference between stranded wire and silk-covered wire? In essence, there is no difference. Silk-covered wire is made of artificial glass wire wrapped around a wire. If impregnated in silicone resin, the temperature can reach 453K, with good insulation performance, high mechanical strength characteristics. Used for precision electrical equipment. Silk charter is made of silk or fiber (nylon, polyester fiber, silk, self-adhesive silk, etc.) in the wire or enameled wire with a layer of insulation. The silk charter has good flexibility and elasticity (the extension length can reach 3-4 times the length of the original spring). Good cold resistance, flame retardant, oil resistance and wear resistance. We can produce various coil spring wires according to different requirements. Specifications are 0.08*105 0.10*80 0.10*100(specifications and number can be produced according to customer requirements). The coated silk wire of the invention is processed outside the enamelled film according to the following process steps :1) the extrusion temperature of the copper flat wire is 460°C-490°C; When cooling, the circulating water temperature is 50°C-60°C, and the circulating oil temperature is 35°C-45°C. 2) Heat treatment of copper flat wire annealing treatment, annealing temperature of 520°C-580°C, steam annealing treatment in the atmosphere; 3) Paint the baking bag several times. The thickness of the paint film is controlled at 1-2 wires, and the total thickness of the paint film does not exceed 14 wires. After each painting, the paint should be dried first, and then the paint should be dried until the thickness of the paint meets the specified requirements.

Silk-covered wire and its processing technology. The utility model relates to a wire winding for a motor coil. The inner layer is copper core, the copper core is coated with lacquer coating, and the polyester glass sintered layer is coated with polyester wire and glass wire mixed around the lacquer coating. By extrusion of copper wire, heat treatment, coating, sintering. The filament covered wire of the invention has the characteristics of high strength of polyester filament and glass filament, has the characteristics of high mechanical strength, and meets the needs of the motor winding process. Based on the production of traditional enamelled wire, the silk-coated wire ensures the solvent of enamelled wire to evaporate fully, reduces the curing time and reduces the curing degree of enamelled wire film. In the sintering process to complete the secondary curing, and evaporation of excess solvent, polyester glass layer is painless sintering, so that the product is truly free of volatile substances, is a real environmental protection electromagnetic wire.
