Offshore floating wind power generation cable

Abstract

The invention discloses an offshore floating wind power generation cable, which comprises conductors, insulating layers, an inner lining layer, an inner protection layer, tensile components, floating components, a waterproof layer, protective layers and an outer sheath, wherein the conductor is coated with the insulating layer by way of extrusion so as to form insulating wire cores, and a plurality of insulating wire cores are stranded into a cable core; the cable core is respectively coated with the inner lining layer and the inner protection layer by way of extrusion; two protective layers are wound outside the inner protection layer, each protective layer consists of a plurality of protective elements which are arranged in the shape of circle, and each protective element is formed by coating the tensile component with the floating component by way of extrusion; the two protective layers are respectively coated with the waterproof layer, the protective layer and the outer sheath by way of outward extrusion; the insulating layers and the inner lining layer are made of thermoplastic elastomeric materials by way of extrusion; and the insulating layer is made of thermoplastic polyolefin (TPO) materials in thermoplastic elastomer (TPE), and the inner lining layer is made of toughened polystyrene (TPS) materials in TPE. The wind power generation cable of the invention has the advantages of low temperature resistance, bending resistance, torsion resistance, abrasion resistance, water blocking, corrosion resistance, weather fastness, high tensile strength, and capability of effectively preventing the damages of stormy waves and other floaters over the sea to the cables.

Description

technical field [0001] The invention relates to a cable, in particular to a cable for offshore floating wind power generation. Background technique [0002] In the context of the world's offshore wind power entering the stage of large-scale development, the construction of China's offshore wind farms has also kicked off. In terms of offshore wind power, the exploitable offshore wind energy resources in the east coast of China amount to about 750 million kilowatts, which not only has huge resource potential but also has good market conditions for development and utilization. Since 2008, my country's offshore wind power resources have maintained a good momentum of development, investment in offshore wind power projects has continued to heat up, and the construction of offshore wind farms has progressed in an orderly manner. [0003] On January 22, 2010, the state issued the "Interim Measures for the Management of Offshore Wind Power Development and Construction", which marked...

AI Technical Summary

Problems solved by technology

The floating body itself has a small specific gravity, so that the specific gravity of the entire cable is smaller than that of water and can directly float on the water. When the cable is used for water operations, although it can float on the water, the appearance is clearly visible and it is easy to maintain. However, the cable Tensile strength, waterproof performance, corrosion resistance, softness and bending performance are relatively poor, so it is not suitable for offshore wind power generation equipment
