Abstract
The utility model discloses a multi-core power cable for an offshore wind-driven generator. The multi-core power cable for the offshore wind-driven generator is characterized in that an insulating layer is extruded to cover a conductor to form an insulating wire core, a plurality of insulating wire cores are stranded and cabled into a cable core, and a lining layer formed through extrusion, a reinforcement layer formed by knitting fibers and an outer sheath layer formed through extrusion are orderly arranged on the cable core from inside outwards, wherein the conductor is formed by multiply stranding a plurality of tinned copper wire irregularly in the same direction. The multi-core power cable for the offshore wind-driven generator is high in flexibility, and has not only properties such as high/low temperature resistance, oil resistance, weather resistance, ultra violet resistance, sea water corrosion resistance and the like so as to adapt to different working environments, but also excellent torsional behavior, and thus is suitable for serving as the special multi-core power transmission connecting line of the offshore wind-driven generator.

Technical field
The utility model relates to the electric power transfer cable, more specifically says a kind of offshore wind power generation machine multi-core power cable, belongs to technical field of electric wires and cables.
Background technology
As the generation mode the most ripe, exploitation condition on the largest scale and commercialized development prospect of technology in the new forms of energy, the development speed of wind power generation attracts people's attention.Becoming as the cable for wind power generation of wind energy generating plant auxiliary products has the cable of huge market potential new varieties, by numerous cable enterprise developments and put on market.
China's wind-force wind power resources is abundant, all is area in spaciousness but wind field mostly is distributed in these places of grassland and coastal area, particularly inshore, wind is large, the temperature temperature difference is large, and cold local temperature can reach subzero below 40 degrees centigrade, in the time of the hottest temperature can reach 45 ℃ and more than.Therefore present universal cable is difficult to reach the requirement of offshore wind power generation occasion.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, provide a kind of pliability strong, not only have the characteristics such as anti-high/low temperature, oil resistant, weather-proof, UV resistant, seawater corrosion resistance with the offshore wind power generation machine that adapts to different operational environments multi-core power cable, be used for the special electric power pipeline of offshore wind power generation machine.
The utility model technical solution problem adopts following technical scheme:
The utility model offshore wind power generation machine with the characteristics of multi-core power cable is: the extruded insulation layer consists of insulated wire cores on conductor, consist of cable core by many eradications edge core twisted synthesizing cable, on described cable core, set gradually from inside to outside the inner covering that extrudes formation, the reinforced layer that the filament braiding consists of and the external sheath layer that extrudes formation; Described conductor is to adopt multiply tin-coated copper thread strand and multiple strand regular in the same way stranded and form.
The utility model offshore wind power generation machine also is with the characteristics of multi-core power cable:
Described conductor adopts the 5th class tinned copper wire that meets GB/T3956.
Described insulating barrier is to extrude by material and formed through vapor crosslinking take silicon rubber, fluorosioloxane rubber or ethylene propylene diene rubber; Described external sheath layer is to extrude and form through vapor crosslinking with neoprene, chlorosulfonated polyethylene rubber or chlorinated polyethylene rubber material.
The laying up pitch of described cable core is 16-30 with the external diameter ratio.
Described reinforced layer adopts the braiding of polyamide fibre line to form, and count is 60-75%.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model conductor cores adopts many zinc-plated thin copper wire thighs strands, twists regular lay configuration again, has guaranteed the electrical safety performance of cable, good bending property and flexibility, by improving stranded lay ratio, makes that cable is more anti-to be reversed;
2, inner covering extrudes formation in the utility model, makes the structure of cable tightr, improves the stability of the construction of cable, also improves the twisting property of cable;
3, the reinforced layer between inner covering and the external sheath layer adopts the Polyamide Yarns of high strength and modulus to be woven in the utility model, has certain tension, strengthening action, and hovering length can reach 100 m;
4, the utility model uses the chloride element rubber class material of high strength, oil resistant, anti-high/low temperature, the better performances such as weather-proof to make sheath, has good low temperature resistant and resistance to wear, and fatigue durability, weather-resistant performance, anti-microbial performance, oil product, chemicals are had fabulous corrosion resistance.Common cable does not have resistance to wear and corrosion resistance.Greatly improved cable useful life when free suspension or fixed installation in the dried tower;
5, the ethylene propylene rubber insulated resistance that adopts in the utility model is high, dielectric loss is less, and the highest long-term permission serviceability temperature of conductor can reach 90 ℃.Finished cable under-40 ℃ low temperature environment, can stand positive and negative each four transfer to once, windup-degree is 360 °, number of times is no less than 3000 times anti-torsion performance test, fracture, jacket surface did not crack conductor after cable testing finished; Cable can suitable environment temperature-45 ℃～+ 110 ℃, operating temperature is-40 ℃～+ 110 ℃;
