Abstract

A tensile and torsion-resistant wind energy cable for wind power generation comprising an outer sheath sequentially from the outside to the inside, armor layer, outer flame retardant layer and outer insulation layer, A support unit is arrange in that outer insulate layer, the support unit comprises a central pipe and three arc-shaped units with an arc cross section, the arc-shaped unit is a sheetwith an arc-shaped cross section extending along the length direction of the cable, A connecting unit is connected between each arc-shaped unit and a central pipe, a plurality of voltage-resistant pipes are fixedly connected on the outer side of the arc-shaped unit, tension ropes are arranged in the central pipe, three cable core wires are arranged in the outer insulation layer, and the cable corewires comprise a conductor, an inner insulation layer, a shielding layer, an inner flame retardant layer and an inner sheath from the inside to the outside. The cable of the invention has good tensile resistance and torsion resistance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a stretch-resistant and torsion-resistant wind energy cable for wind power generation. Background technique [0002] With the advancement and development of technology, cables are now indispensable electrical equipment in life and production. Cables can be divided into power cables, signal cables, etc. according to different uses. cables and other cables. Since the cables for wind power generation pass through the inside of the tower of the wind power generation device, the height of the tower is high, and the cables will be twisted repeatedly during use, so the requirements for the mechanical properties of the cables are relatively high. There are many types of wind energy cables at present, but they still cannot meet all needs. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the defects of the prior art and provide a str...
