Novel wind power cable

Abstract

The invention discloses a novel wind power cable. A plurality of wire cores are coated with ethylene-propylene rubber to form the cable core. A stainless steel wire shielding layer, an aramid layer and a sheath layer formed by PUR elastomer composites are sequentially arranged outside the cable core. In the main structure, due to the use of the ethylene-propylene rubber and the aramid, the cable is lighter, and natural hanging of the cable is facilitated; the aramid layer and the stainless steel wire shielding layer improve the tension-resistance and distortion-resistance mechanical performance of the cable; and the novel wind power cable is formed by aging-resistance and corrosion-resistance materials and is suitable for being matched with a wind power generator.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, in particular, it is suitable for wind power cables specially used for wind power generators. Background technique [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 existi...

[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
