Embodiment 1

[0035] See figure 1 , a cable for shallow sea wind power generation in this embodiment is particularly suitable for use in water situations, and can also be used underwater, including a conductor 1, a water blocking tape 2, an insulating layer 3, an inner lining 4, a rubber strip 6 and a shielding Layer 5. The first water blocking tape 21 and the extruded insulation layer 3 are wrapped around the conductor 1 to form an insulated wire core, and multiple insulated wire cores are stranded to form a cable core; the first inner lining layer 41 and the shielding layer 5 are wrapped around the cable core in turn , the second water blocking strip 22 , and the second inner lining layer 42 .

[0036] Conductor 1 is made of tinned annealed copper wire; the pitch ratio of strands made of copper wire is 15 to 18 times;

[0037] The insulating layer 3 and the first inner lining layer 41 are extruded from TPO material in TPE, and the second inner lining layer 42 is extruded from TPS materi...

Embodiment 2

[0043] still see figure 1 , this embodiment 2 increases the armor layer 7 and the outer sheath 8 on the basis of the embodiment 1, in order to meet the requirements of wear resistance and tensile resistance during long-term underwater use. Specifically, its structure is as follows: the first water blocking tape 21 is wrapped around the conductor 1, and the insulating layer 3 is extruded to form an insulated wire core, and a plurality of insulated wire cores are stranded to form a cable core; rubber strips are filled in the gaps of the insulated wire cores 6. Wrap the first inner liner 41, the first inner liner 41, the shielding layer 5, the second water blocking tape 22, the second inner liner 42, the first armor layer 71, the third The water blocking tape 23 , the second armor layer 72 , the fourth water blocking tape 24 and the outer sheath 8 .

[0044] The first armor layer 71 adopts aviation steel wire rope, and a layer of zinc is plated on the surface of the aviation steel...

Abstract

The invention discloses a cable for shallow sea wind power generation, which comprises a conductor, water-blocking tapes, an insulating layer and lining layers, wherein, the first water-blocking tape and the extruded insulating layer are wrapped sequentially outside the conductor to form insulating wire cores, and a plurality of insulating wire cores are twisted together to form a cable core; the first lining layer and the second water-blocking tape are wrapped sequentially outside the cable core; and the insulating layer and the first lining layer are formed by extruding a thermoplastic elastomer (TPE). In the invention, the insulating layer is made of a thermoplastic olefin (TPO) material in the TPE and the first lining layer is made of a thermoplastic starch (TPS) material in the TPE, wherein, the TPE has good electrical property, good mechanical property, excellent low-temperature bending property and excellent torsion resistance, high long-term working temperature up to 125 DEG C, better water resistance and excellent salt-fog resistance, and especially the TPE can still maintain good flexibility at -60 DEG C; and TPO has more excellent electrical property, and TPS has better water resistance than that of the TPO.

Description

technical field [0001] The invention relates to a cable, in particular to a cable for shallow sea wind power generation. Background technique [0002] Wind power generation is one of the power generation methods with the most mature technology, the most large-scale development conditions and the most promising commercial development among renewable energy sources. It is of great significance for adjusting the energy structure and mitigating environmental pollution. Strategic choices for development. Countries all over the world pay more and more attention to wind power generation technology. my country's wind energy resource reserves rank first in the world, mainly concentrated in the northwest, northeast and coastal areas. Since the reform and opening up, wind power has made great progress in my country. By 2003, more than 40 wind farms had been built, with an installed capacity of 567,000 kilowatts, ranking ninth in the world. While the construction of onshore wind farm...
