Problems solved by technology
For example, wind energy cables generally use low-temperature (-40°C or -45°C silica gel insulation) rubber, although they meet the performance requirements of flexible and twistable wind energy cables, but the cables have poor tear resistance, short effective service life and low temperature installation. Due to environmental restrictions, the twisting performance of the cable still cannot meet the stringent requirements of twisting performance for wind power generation.

Abstract
The invention discloses a distortion-resistance wind power generation cable sheath material and a cable. The cable material comprises the following components in weight parts: 100 parts of chlorinated polyethylene, 10-30 parts of amorphismcopolymer, 10-20 parts of cold-resistant plasticizer, 40-80 parts of reinforcing filler, 5-15 parts of nanosacle inorganic active agent, 2.5-5 parts of cross-linking agent, 2-5 parts of cross-linking assistant agent, 1-2.5 parts of antioxidant antiager and 10-30 parts of inorganic fire retardant, wherein the amorphismcopolymer is a mixture of amorphismpolyolefinthermoplasticelastomer and chlorinated polyethylene elastic body; and the nanoscale inorganic active agent is nanoscale zincoxide and magnesiumoxide. The cable of the invention has low-temperature resistance (-60DEG C)and distortion resistance, excellent flexibility, improves the homogenisieren property of the other materials by adding the nanoscale inorganic active materials, improves the molecular structure, has better flexibility because of the uvio-resistance, and has the characteristics of distortion, cold, oil and corrosion resistance and the like.
Description
technical field [0001] The invention relates to a cable sheath material, in particular to a twist-resistant wind power generation cable sheath material; the invention also relates to a cable made of the above material. Background technique [0002] Cables for wind power generation work in a special environment, and have high requirements for their low-temperature bending performance, torsion performance, crack resistance, corrosion resistance and other performance. Wind power cables with high performance such as high and low temperature resistance and twist resistance are imperative. Row. The structure of the existing wind power cable mainly adopts multi-strand multi-crossing, the conductor surface has a tin-plated layer, and a composite non-woven fabricisolation layer is arranged outside the layer. The insulating material on the surface of the isolation layer is a rubber compound, and the rubber compound sheath is extruded outside. For example, wind energy cables generall...
