Abstract

The invention relates to a salt corrosion resistant and twisting resistant power cable for ocean wind power and a manufacturing method of the power cable. A stranded copper conductor is uniformly wrapped in a salt corrosion resistant and twisting resistant extruded rubber insulation layer to form a power cable insulated core; a plurality of power cable insulated cores are mutually stranded to form a power cable core; the power 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 power cable provided by the invention adopts the low-strength non-woven fabric longitudinal wrap which completely fits the power cable insulated cores in shape, so that gaps between the low-strength non-woven fabric longitudinal wrap and the power 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 power cable, in particular to a salt-corrosion and torsion-resistant power cable for marine wind power. The invention also relates to a method for manufacturing a salt-corrosion-resistant torsion-resistant power 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 long-term...
