Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of instrument cable, in particular to a computer instrument cable for ocean energy power generation platform. BACKGROUND

[0002] The ocean energy power generation platform is a mobile small power station on the sea, which is an organic combination of small power station and ship engineering, and can provide safe and effective energy supply for offshore oil exploitation and remote islands, and can also be used in the field of high-power ships and seawater desalination.

[0003] The energy of the ocean includes the kinetic energy of seawater (including tidal current energy, wave energy, etc.), the energy contained in the temperature difference between the surface seawater and the deep seawater, the energy of tides, etc. (see tidal power station and ocean energy power station). Ocean energy generally refers to renewable energy contained in the ocean, mainly including tidal energy, wave energy, tidal current energy, seawater temperature difference energy, seawater salinity difference energy, etc.

[0004] China is the country with the most tidal power stations in the world. From the 1950s to the 1970s, nearly 50 tidal power stations were built, but according to the statistics in the early 1980s, only 8 power stations were still operating normally. Jiangxia Power Station is the largest tidal power station in China, which has been operating normally for nearly 20 years.

[0005] However, the development of special cables for ocean energy power generation platforms in China is indeed a blank, and some cables even use ordinary marine cables instead. The service life of the insulation sheath of the traditional marine cable is low under the marine climate environment, and the number of cables needs to be replaced for a long time and it is difficult to replace. The ordinary computer instrument cable does not have the performance of high flame retardation, longitudinal and radial waterproofness, resistance to marine climate, and resistance to swinging and tilting, and the protection of the entire circuit system is weak, so it is not enough to support the data transmission of the complex environment of the ocean energy power generation platform equipment. Therefore, the special cable for ocean energy power generation platform relies 100% on imports, and there is no mature product on the market at present. SUMMARY

[0006] Based on the above problems, the purpose of the present application is to provide a computer instrument cable for ocean energy power generation platform, to improve the current situation that the cable relies on imports, maintenance is difficult, and procurement cost is high, to meet the on-site use, and to fill the market gap.

[0009] Particularly, the outer surface of braided partial screen, braided total screen and braided reinforcing layer is wrapped with a layer of halogen-free flame-retardant water-blocking expansion tape.

[0010] Particularly, four cable cores are provided, the four cable cores are stacked against each other, and a braided tensile rope is arranged in the center gap and filled with a halogen-free flame-retardant water-blocking filling rope.

[0011] Particularly, each cable core is stranded by two insulated wire cores, and arranged in a ring array with the braided tensile rope as the center.

[0012] Particularly, the braided reinforcing layer and the braided tensile rope are woven by aramid braided wire and water-blocking yarn.

[0013] Particularly, the tinned soft copper conductor is stranded by extremely fine tinned oxygen-free soft round copper wire and water-blocking yarn.

[0014] Particularly, the insulating layer is extruded by double-layer co-extrusion technology to obtain inner insulation and outer insulation made of halogen-free low-smoke flame-retardant irradiation cross-linked polyolefin material, the eccentricity of the inner insulation is less than or equal to 25%, and the total eccentricity of the insulation is less than or equal to 15%.

[0015] Particularly, the braided partial screen and the braided total screen are woven by tinned copper wire.

[0016] Particularly, the inner sheath is made of medium-density polyethylene material.
