Problems solved by technology
[0002] At present, with the large-scale use of coal, the environment is becoming more and more polluted. The air contains a large number of flying dust particles, which greatly affects people's lives. The demand for new energy is becoming more and more urgent. As a new pollution-free Energy has received more and more attention. The performance of wind energy cables connected to wind turbines greatly affects the reliability of wind power generation. Since the various components of wind power generation are generally in harsh environments, wind energy cables are required to withstand high temperature and low temperature. Change, corrosion resistance, aging resistance, radiation resistance, tensile strength, high flexibility and twist resistance, etc., but the existing cables cannot meet the above requirements

Embodiment Construction
[0010] exist figure 1 Among them, the wire core of the fan suspension cable is composed of a plurality of copper wires that are bundled and re-stranded. The conductor 1 is wrapped with an insulating layer 2 of ethylene-propylene rubber material. Several wire cores are twisted to form a cable core, which is wrapped The ethylene-propylene rubber filling layer 3, the ethylene-propylene rubber filling layer 3 is wrapped with the copper wire shielding layer 4, and the copper wire shielding layer 4 is an outer sheath 5 composed of a high tear-resistant silicone rubber compound; a stainless steel wire reinforcing rib 6 is also Wrapped in the outer sheath 5, and the center distance between the stainless steel wire reinforcing rib 6 and the cable core is greater than the average distance from the cable core to the outer surface of the outer sheath 5.

Provided is a fan suspension cable. An outer sheath composed of an ethylene-propylene rubber filling layer and a high-tear-resistance silicone rubber compound is adopted, and the distance between a stainless steel wire reinforcing rib in the outer sheath and the center of the cable core is greater than the average distance from the center of the cable core to the outer surface of the outer sheath. The stainless steel wire reinforcing rib slightly away from the outer layer of the cable enables the cable to be suspended vertically. The adopted outer sheath composed of the ethylene-propylene rubber filling layer and the high-tear-resistance silicone rubber compound is a material which is aging-resistant, corrosion-resistant, tensile and compressive, distortion-resistant and the like. Therefore, the fan suspension cable of the invention is suitable for field use and more suitable for suspension use.
Description
technical field [0001] The invention belongs to the technical field of electric wires and cables, in particular, it is suitable for a special wind power cable used for suspending wind power generators to the ground.
