Soft electric energy output cable for large-power wind driven generator

Abstract

The invention discloses a soft electric energy output cable for a large-power wind driven generator. The soft electric energy output cable comprises a conductor, an insulating layer, a wrapping layer and a protective sleeve layer, wherein the conductor is arranged at the center of the cable; the insulating layer is arranged on the outer layer of the conductor; the wrapping layer is arranged on the outer layer of the insulating layer; the protective sleeve layer is arranged outside the wrapping layer; an adhesive is arranged between the conductor and the insulating layer; and a filling layer is arranged between the insulating layer and the wrapping layer. According to the invention, by using a silicon rubber insulating material, the requirement that the cable can be twisted for 360-720 degrees in both a clockwise direction and an anticlockwise direction can be satisfied under the situation of outputting electric energy in a wind power generating tower body in a vertically laid state; and as the filling layer is designed between a cable core and the wrapping layer, the formula of a filling material is optimized and the softness is good; in addition, as a heterogeneous twisting structure with 1-6 cores is designed for the cable conductor and a cable core soft structure is developed, the anti-twisting performance of the cable is improved.

Description

technical field [0001] The invention relates to a cable, in particular to a flexible electric energy output cable for a high-power wind generator. Background technique [0002] Wind turbines are mostly located in open areas with abundant wind energy. The long-term working environment temperature is low, the surface of the cable is easy to crack, and the wind turbine is easy to twist and break the cable due to the rotation of the shaft due to the change of wind direction. When twisting, the insulation layer is easy to crack and cause a short circuit. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a flexible electric energy output cable for a high-power wind generator. [0004] The technical scheme adopted in the present invention is: a flexible electric energy output cable for a high-power wind power generator, including a conductor, an insulating layer, a wrapping layer and a sheath layer...
