Salt-corrosion-resistant torsion-resistant control cable for offshore wind power and manufacturing method thereof

Abstract

The invention relates to a salt corrosion resistant and twisting resistant control cable for ocean wind power and a manufacturing method of the control cable. A stranded copper conductor is uniformly wrapped in a salt corrosion resistant and twisting resistant extruded rubber insulation layer to form a control cable insulated core; a plurality of control cable insulated cores are mutually stranded to form a control cable core; the control cable core is wrapped in a low-strength non-woven fabric longitudinal wrap; and the low-strength non-woven fabric longitudinal wrap is wrapped in an extruded sheath. The control cable provided by the invention adopts the low-strength non-woven fabric longitudinal wrap which completely fits the control cable insulated cores in shape, so that gaps between the low-strength non-woven fabric longitudinal wrap and the control cable 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 control cable, in particular to a salt-corrosion and torsion-resistant control cable for marine wind power. The invention also relates to a method for manufacturing a salt-corrosion-resistant torsion-resistant control cable for marine wind power. Background technique [0002] As the utilization of wind power for landing has matured, the country has begun to promote the utilization of marine wind power, but currently there is no cable that can fully meet the operating conditions of marine wind power. It is used for marine wind power cables, and most of them are used for onshore wind power. It is used for marine wind power, or a cable with certain properties required for marine wind power cables. However, the performance of the cable for land-use wind power does not consider the special environment of marine wind power, especially the long-term resistance to marine salt, acid and alkali corrosion, oily corrosion and seawater damp i...

Problems solved by technology

[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
