Wind energy cable

Abstract

The invention discloses a wind energy cable which is characterized by comprising a cable core, wherein the cable core comprises two V-shaped nylon frameworks arranged in a back-to-back mode, wire cores are arranged in a left cavity and a right cavity which are formed by the inner sides of the two V-shaped nylon frameworks and the outer side faces of the two V-shaped nylon frameworks respectively, the wire cores comprise conductors, the outer sides of the conductors are wrapped by crosslinking ethylene tetrafluoroethylene copolymer insulation layers, the multiple conductors and multiple steel wire ropes are twisted in a paired mode, the outer sides of the multiple conductors and the multiple steel wire ropes are wrapped with tensile resistant belts, and the outer side of the cable core is wrapped with a copper wire braided tensile resistant barrel, an aluminum-magnesium-silicon alloy wire braided shielding layer and an outer sheath in sequence. The wind energy cable can achieve electric energy transmission and signal transmission at the same time, and has the advantages of being good in torsional property, waterproof, flaming resistant, fatigue resistant, electromagnetic interference resistant, good in flexibility, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wind energy 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 sheathing materials are insufficient in heat resistance, aging resistance, acid and alkali resistance, oil resistance and other medium corrosion resistance. Contents of the invention [0004] The purpose of the present invention is to provide a wind energy cable in order to remedy the defects of the prior art. The cable outer sheath material of the present invention has good performances such as heat resistance, aging resista...
