Cable for seabed wind power generation

Abstract

The invention discloses a cable for seabed wind power generation. The cable for the seabed wind power generation comprises a cable core formed by twisting multiple insulated wire cores, padding layers are arranged in the clearances of the cable core, a foaming lining layer is arranged outside the cable core, the foaming lining layer is wrapped with a waterproof tape in a winding mode, high-intensity aramid yarns are woven outside the waterproof tape, a metal armoring layer is extruded outside the high-intensity aramid yarns, and an outer sheath is extruded on the outermost layer of the cable core. A monitoring wire core is arranged in the center when the insulated wire cores are twisted, and monitoring wire cores extruded together in pairs are arranged in the clearances of the cable core to form an 8 shape. The cable for the seabed wind power generation has a floating function, high tensile strength and monitoring capacity, and also has good shielding performance and anti-interference performance, the service life is prolonged, and due to the fact that the monitoring cores are arranged inside, the cable for the seabed wind power generation has quite high safety performance.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a cable for wind power generation. Background technique [0002] Offshore wind turbines are generally located on the sea surface 1 to 3km away from the coast land. The part of the coast close to the land is actually a tidal flat. With the ebb and flow of the tide, it is sometimes shallow sea and sometimes land. At present, most offshore wind farms are equipped with wind power There are two types of cables (1) most of them are submarine cables, which are laid on the seabed for power transmission; (2) cables for wind power generation floating on the sea. [0003] And there are following problems and shortcoming in prior art: [0004] (1) Submarine cables have the following problems and shortcomings: [0005] ① Submarine cables are inconvenient to install and lay; [0006] ② Submarine cables are inconvenient to move and maintain; [0007] ③It cannot be merged and shared with wind...

AI Technical Summary

Problems solved by technology

[0005] ① Submarine cables are inconvenient to install and lay;

[0006] ② Submarine cables are inconvenient to move and maintain;

[0007] ③It cannot be merged and shared with wind power generation cables, and joints are required, and there are potential safety hazards when working in water

[0009] ① The tensile strength of the floating cable is not high, and the material used is light weight and flexible fine hemp rope, which is easy to disconnect the cable when encountering large waves during use;

[0010] ② Floating cables do not have a monitoring function. During the regular inspection of cables by maintenance personnel, inspection ships may break the cables and cause electric leakage, which poses a safety hazard

[0012] The disadvantages of the above-mentioned cables are that there are three monitoring wire cores in the inner lining of the cable. Once the three wire cores are damaged, they will not work at all; in addition, the shielding effect of the cable is poor, and the anti-interference performance is poor.
