Wind energy anti-torque cable

Abstract

The invention discloses a wind energy anti-torque cable. The wind energy anti-torque cable comprises a cable core comprising an H-shaped silica gel frame, wherein a main wire core and a control wire core are placed on the left side and the right side of the H-shaped silica gel frame respectively, the main wire core comprises a first oval silica gel frame, a first tensile belt is wrapped around the first oval silica gel frame, a first elastic cushion plate is placed in the first oval silica gel frame, main conductors are placed on the two sides of the first elastic cushion plate respectively, a polyimide insulating layer and an aluminum plastic composite film shielding layer are sequentially wrapped around each main conductor, the control wire core comprises a second oval silica gel frame, a second tensile belt is wrapped around the second oval silica gel frame, and a second elastic cushion plate is placed in the second oval silica gel frame. The wind energy anti-torque cable can achieve electric energy transmission and signal transmission at the same time, and has the advantages of being good in torsional property, waterproof, resistant to flame resistant to fatigue and electromagnetic interference, good in flexibility, water proof and long in service life, achieving flame retardance and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wind energy torsion-resistant cable. Background technique [0002] Wind energy cables play an important role in the development and application of wind energy. Due to the harsh environment of wind power generation, the wind turbines have a long service life, and the cables rotate continuously with the wind turbines, the performance requirements of the cables are relatively high. The existing wind energy cables still cannot fully meet the needs. [0003] Traditional cable sheath materials have poor low temperature resistance, and are prone to embrittlement and cracking in low temperature environments, shortening the service life of cables. Contents of the invention [0004] The object of the present invention is to provide a wind energy torsion resistant cable in order to remedy the defects of the prior art. The cable outer sheath material of the invention has good low temper...
