Cold-resistant corrosion-resistant flame-retardant water-blocking scandium aluminum alloy conductor low-voltage cable used for offshore wind power generation

Abstract

The invention discloses a cold-resistant corrosion-resistant flame-retardant water-blocking scandium aluminum alloy conductor low-voltage cable used for offshore wind power generation. The cable comprises a cable body. The cable body comprises a wire core and a protective layer arranged on the wire core. The protection layer comprises a water-blocking layer, an inner protection layer, a pressure-resistant layer and an outer sheath successively from inside to outside. The wire core is located on a surface of the inner protection layer and rubber air bags are arranged at equal intervals along alength direction of the wire core. Silicone tubes are annularly arranged on an outer surface of the rubber air bags at equal intervals. At least ten groups of air cavities are annularly arranged at positions, corresponding to the rubber air bags, of a side wall of a compression-resistant layer at equal intervals. Each group of air cavities is formed a plurality of strip-shaped air chambers, air channels are evenly arranged between each strip-shaped air chamber and the inner wall of the compression-resistant layer, each air channel is connected with the corresponding silicone tube, and the wirecore comprises three power wire cores and a ground wire core. In the invention, good cold-resistant, flame-retardant, water-blocking and wear-resistant properties are possessed, good compression resistance performance is achieved, and a power wire core conductor is effectively prevented from being snapped and bent.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cold-resistant, corrosion-resistant, flame-retardant, water-resistant scandium-aluminum alloy conductor low-voltage cable for offshore wind power generation. Background technique [0002] With the continuous development of my country's industry and the rapid development of wind power generation, the amount of cables used is also increasing. However, the cold-resistant, corrosion-resistant, flame-retardant, and water-resistant cables suitable for offshore wind power generation have not yet been the main raw materials for cables. Is the insulation, sheath and conductor. The main component of the conductor used in the manufacture of cables is copper, accounting for about 60% of the total amount of copper used. But my country's copper resources are very short. With the depletion of China's copper mine resources, 70% of China's copper mines need to be imported, which is highly depend...

AI Technical Summary

Problems solved by technology

[0003] The existing wires and cables cannot meet the requirements due to poor bending performance, and at the same time, they have no cold resistance, corrosion resistance, flame retardancy, and water resistance.

Therefore, so far, there is no 0.6-1kV flexible cable with low price and excellent performance, which is cold-resistant, corrosion-resistant, flame-retardant, and water-resistant, suitable for offshore wind power generation.
