Problems solved by technology

[0002] At present, the lead flexible cable for wind power motors is mainly used for connecting the spindle and rotor of wind power generators. It is mainly composed of copper conductors and silicone rubber insulation layers extruded on the copper conductors. The silicone rubber insulation layer is extruded from a single silicone rubber. It is made by vulcanization process. Due to the poor mechanical properties of silicone rubber itself, the silicone rubber insulation layer of the cable is easy to be scratched and cracked when used. The wear of the rubber insulating layer is very large, and it is easy to damage the silicone rubber insulating layer, which will cause an open circuit and cause an accident, resulting in a high repair cost of about 1 million yuan per wind power motor

Embodiment Construction

[0016] Example 1, (1), the outer surface of the silicone rubber cable is wrapped with polyester film, the thickness of the polyester film is 0.25mm, so that it produces a layer of isolation layer; the silicone rubber cable consists of 950 copper wires of Φ0.40mm Copper conductor and silicone rubber insulation layer extruded outside the copper conductor;

[0017] (2), put the 4500D aramid fiber into 24 braided wraps on the polyester film surface of the cable after wrapping the polyester film, so that the weaving density of the aramid fiber on the polyester film reaches more than 90%;

[0018] (3) The surface of the aramid fiber of the cable prepared in step (2) is sprayed with a layer of impregnated insulating resin, and then baked at 100°C for 2 minutes to cure the impregnated insulating resin, and the finished silicone rubber insulated wind power motor leads soft The cable; the impregnated insulating resin is grade F impregnated insulating resin 319-5F produced by Jiangyin De...
