Problems solved by technology

[0005] Tensile-resistant and torsion-resistant flexible cables for ordinary wind turbines are generally insulated with 90°C ethylene-propylene rubber, and the sheath is made of chlorosulfonated polyethylene rubber sheath, while flexible cables for 10MW offshore wind turbines have relatively high requirements for insulation and sheath materials. The tensile strength, aging resistance, tear resistance and other properties of the existing wind turbine tensile and torsion resistant flexible cables are relatively low

Abstract

The invention belongs to the technical field of wires and cables, and particularly relates to a flexible cable for a 10MW offshore wind generating set and a preparation method of the flexible cable. The flexible cable for the 10MW offshore wind generating set comprises a conductor, a reinforcing layer, an insulating layer and a sheath layer; the reinforcing layer is arranged in the outer side of the conductor, the insulating layer is arranged in the outer side of the reinforcing layer, and the sheath layer is extruded outside the insulating layer; the conductor comprises a single copper wire and a copper foil wire, the copper foil wire comprises a Kevlar bulletproof wire fiber wire and a copper foil metal belt, the copper foil wire is supported by the Kevlar bulletproof wire fiber wire and is formed by wrapping the copper foil metal belt, and the reinforcing layer is formed by weaving Kevlar bulletproof wires. According to the flexible cable for the 10MW offshore wind generating set and the preparation method of the flexible cable, the torsion resistance and the tensile property of the cable can be remarkably improved, and meanwhile, the cable also has excellent high and low temperature resistance, ageing resistance, salt mist resistance and flame retardance.

Description

technical field [0001] The invention belongs to the technical field of wires and cables, and in particular relates to a flexible cable for a 10MW offshore wind power generating set and a preparation method thereof. Background technique [0002] current technology: [0003] At present, offshore wind energy resources are abundant, and my country's usable sea area is more than 3 million square kilometers. It is one of the countries with the most abundant wind energy resources in Shanghai in the world. The preliminary estimate of the wind energy resources that can be developed and utilized is about 1 billion kW, of which, offshore The wind energy reserves that can be developed and utilized are about 750 million kW. With the development of the wind power market, the installed capacity of wind turbines is increasing year by year, and the demand for wind power cables matching them will increase. The known single-core wind power cable is composed of three parts: conductor, insulati...
