Fan-dedicated cable

Abstract

Disclosed is a fan-dedicated cable. A plurality of wire cores each coated with a stainless steel wire shielding layer are wrapped in an ethylene-propylene rubber insulation layer. The ethylene-propylene rubber insulation layer is covered with a sheath layer composed of a PUR elastomer compound. By simplifying the cable structure and choosing a low-density ethylene-propylene rubber insulation material, the weight of the cable is reduced. Each core wire is separately wrapped in a stainless steel wire shielding layer, so that an electromagnetic shielding effect is achieved, and the tensile, compressive and distortion-resistant mechanical properties of the wire cores are improved.

Description

technical field [0001] The invention relates to a special cable for wind power generators, especially suitable for use from wind power generators to the vertical part of the ground. 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 existing cables ...

[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
