[0006] The invention patent with the publication number CN101838424A discloses a twist-resistant wind power generation cable sheath material and cable. The sheath uses chlorinated polyethylene as the raw rubber base material, which has low temperature resistance to -60°C and anti-twist performance, but does not have seawater resistance. Salt, acid, alkali corrosion and resistance to seawater wet immersion, not suitable for marine wind power environment; at the same time, the cable insulation and sheath are double-layer co-extruded, which is not conducive to the separation of cable end insulation and sheath during construction and installation

Abstract

The invention relates to a salt corrosion resistant and twisting resistant composite cable for ocean wind power and a manufacturing method of the composite cable. Power cable insulation layers, control cable insulation layers and meter cable insulation layers are all salt corrosion resistant and twisting resistant rubber insulation layers and are mutually stranded to form a composite cable core; the composite cable core is wrapped in a low-strength non-woven fabric longitudinal wrap on the periphery; and the low-strength non-woven fabric longitudinal wrap is wrapped in an extruded sheath. The composite cable provided by the invention adopts the low-strength non-woven fabric longitudinal wrap which completely fits insulated cores in shape, so that gaps between the low-strength non-woven fabric longitudinal wrap and the insulated cores are eliminated convenience is provided for stopping flame from spreading inwards under a combustion condition and the resistance to moisture impregnation is enhanced; and meanwhile, the low-strength non-woven fabric longitudinal wrap can ensure that the sheath is not stuck to the insulated cores, and provides convenience for stripping the sheath in a construction process without damaging the insulated cores.

Description

technical field [0001] The invention relates to a composite cable, in particular to a salt-rot and torsion-resistant composite cable for marine wind power. The invention also relates to a method for manufacturing a salt-corrosion-resistant torsion-resistant composite cable for marine wind power. Background technique [0002] With the maturity of land-use wind power utilization, the country has begun to promote the use of offshore wind power, but at present there is no cable dedicated to offshore wind power that can fully meet the operating conditions of offshore wind power to match it, and most of them are matched with cables originally used for land-use wind power It is used for offshore wind power, or a cable with certain performance required by the cable for offshore wind power is used. However, the performance of cables for land-use wind power does not take into account the special environment of offshore wind power, especially does not have the ability to withstand lon...
