Waterproof radiation-resistant cable for offshore power generation

Abstract

The invention relates to a waterproof radiation-resistant cable for offshore power generation. The cable comprises a cable core, an insulating layer, a shielding layer, an ultraviolet-proof layer andan outer wrapping layer. The insulating layer, the shielding layer, the ultraviolet-proof layer and the outer wrapping layer sequentially wrap the cable core from inside to outside. A waterproof framewhich is in line contact with the shielding layer is wrapped between the insulating layer and the shielding layer, and a gap between the waterproof frame and the shielding layer is filled with water-absorbing expansion rubber for further enhancing waterproof capacity. Compared with the prior art, seawater permeating into the cable is blocked outside the insulating layer through the waterproof frame of a triangular structure, water is absorbed through the water absorption expansion rubber arranged on the side edge of the waterproof frame, and the interior of the cable is kept dry. Secondly, the waterproof performance of the cable is further improved through the polyurethane waterproof coating. The possibility of short circuit of the cable is greatly reduced, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a waterproof and radiation-resistant cable for offshore power generation. Background technique [0002] In today's environment where fossil energy resources such as petroleum and coal are increasingly scarce, wind energy, as a green energy resource that can be continuously and sustainably utilized in nature, has a very great application prospect. Offshore wind power generation embodies the highest level of current wind power generation technology. [0003] Offshore power generation cables are important components of offshore power generation equipment, and the quality of offshore power generation cables can directly affect the operation and service life of offshore power generation equipment. Offshore power generation cables are often used in extremely harsh environments such as humidity and high ultraviolet radiation. It is required that the offshore power generation cables have...

AI Technical Summary

Problems solved by technology

Offshore power generation cables are often used in extremely harsh environments such as humidity and high ultraviolet radiation. It is required that the offshore power generation cables have high waterproof and anti-ultraviolet radiation performance to improve the service life of offshore power generation cables; while the existing market The waterproof performance of the cables used for offshore power generation is average, and can only be used for a short period of time. After a long time, the inside of the cable is prone to water and moisture, resulting in a short circuit of the cable and damage to offshore power generation equipment.
