Salt-deposition-preventing and oil-resistant type sea wind-power soft cable

Abstract

The invention discloses a salt-deposition-preventing and oil-resistant type sea wind-power soft cable. The cable comprises a conductor, an isolating band layer arranged on the exterior of the conductor in a wrapping manner, a conductor shielding layer arranged on the exterior of the isolating band layer in an extruding manner, a rubber insulating layer arranged on the exterior of the conductor shielding layer in an extruding manner, an insulating shielding layer arranged on the exterior of the rubber insulating layer in an extruding manner, an inner semi-conductive nylon band layer arranged on the exterior of the insulating shielding layer in a wrapping manner, a copper wire weaving shielding layer arranged on the exterior of the inner semi-conductive nylon band layer, an outer semi-conductive nylon band layer arranged on the exterior of the copper wire weaving shielding layer in a wrapping manner, an inner sheath layer arranged on the exterior of the outer semi-conductive nylon band layer in an extruding manner, an aramid yarn weaving shielding layer arranged on the exterior of the inner sheath layer, a water-blocking band layer arranged on the exterior of the aramid yarn weaving shielding layer in a wrapping manner and an outer sheath layer arranged on the exterior of the water-blocking band layer in an extruding manner from inside to outside in sequence. The finished cable is highly flexible, and the outer sheath layer has excellent waterproof performance, salt deposition prevention and oil resistance, so that the salt is suitable for main circuits for electric energy transmission of sea wind power stations in salt lakes and coastal regions.

Description

technical field [0001] The invention relates to the technical field of transmission and distribution cables, in particular to a salt-free and oil-resistant offshore wind flexible cable. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Global wind energy is about 2.74×10 9 MW, of which the available wind energy is 2×10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. [0003] my country's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts. Coastal provinces such as Shandong, Jiangsu, Fujian, Guangdong, Guangxi, and Hainan have successively carried out the construction of wind power stations. The difficulties in the construction of the power station are: as the transmission and distribution cables for transmitting electric energy, because the to...

AI Technical Summary

Problems solved by technology

It solves the problem that the existing offshore wind flexible cable is easy to stick to salt, and the cable sheath is prone to cracking and softening due to the influence of oil and gas, which leads to the short service life of the cable
