Tension type sea floating type wind power generation cable

Abstract

The invention discloses a tension type sea floating type wind power generation cable. The cable comprises a cable core formed by twisting multiple power cores. The cable core is externally provided with a foaming lining layer; the middle of the foaming lining layer is provided with a monitoring core; the foaming lining layer is wrapped by a water blocking band; a high-strength aramid fiber yarn is braided outside the water blacking band; and the high-strength aramid fiber yarn is wrapped by an oversheath in an extruding manner. The cable provided by the invention has a floating function, the tensile strength is quite high, the service life is prolonged, and since the monitoring core is arranged inside the cable, the cable has quite high safety performance.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a tension-resistant sea-floating wind power generation cable. 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 ...

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
