Abstract

A corrosion-resistant low-voltage power cable for wind energy belongs to the technical field of cables, and in particular relates to a cable used in the field of wind energy. It includes two cable cores, each cable core includes a steel core, seven conductors are arranged outside the steel core, and a halogen-free flame-retardant cross-linked polyolefin co-plant insulation layer is arranged on the outside of the seven conductors. A high-strength polypropylene filling layer is set on the outside of the high-strength polypropylene filling layer, and the outer side of the high-strength polypropylene filling layer is wrapped with a water-blocking tape around the cladding. The invention adopts the steel core and the steel wire braided layer to increase the tensile strength; the outer protective layer adopts polyurethane material to prevent the corrosion of seawater and the destruction of marine organisms; meanwhile, it has the effect of softness.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a cable used in the field of wind energy. Background technique [0002] The existing power cables used in the wind energy field are produced according to the GB / T12706-2008 standard, and the outer sheath material has poor corrosion resistance, insufficient tensile strength, and the cables are not flexible. Contents of the invention [0003] The object of the present invention is to provide a corrosion-resistant, high-tensile-strength, flexible cable for the field of wind energy. [0004] The object of the present invention is achieved in this way: a corrosion-resistant low-voltage power cable for wind energy, including two cable cores, each cable core includes a steel core, seven conductors are arranged outside the steel core, and no conductors are arranged outside the seven conductors. Halogen flame-retardant cross-linked polyolefin co-crop insulation layer, the ou...
