Abstract
The utility model discloses a single-core power cable used for an offshore aerogeneator. The single-core power cable is characterized in that an insulating layer is extruded from a conductor to form an insulating conductor core; a reinforced layer formed by braiding fibers is arranged on the surface of the single insulating conductor core; an oversheath layer is extruded from the reinforced layer; and the conductor is formed by standard intertwisting , i.e., stranding and compound stranding of multiple tin-coated copper wires in the same direction. The single-core power cable used for the offshore aerogenerator is characterized by strong flexibility, high and low temperature resistance, oil resistance, weather resistance, ultraviolet ray resistance, sea water corrosion resistance and the like, and can adapt to different working environments; and excellent torsion features of the single core power cable enables the single core power cable to be used as special power-transmission connecting lines for the offshore aerogenerator.
Description
Technical field
The utility model relates to the electric power transfer cable, more specifically says a kind of offshore wind power generation machine single-core power cables, 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, anti-high/low temperature, oil resistant, weather-proof, UV resistant, seawater corrosion resistance, the offshore wind power generation machine single-core power cables that can adapt to the different operating environment is carried connecting line as the special electric power of offshore wind power generation machine.
The utility model is that the technical solution problem adopts following technical scheme:
A kind of offshore wind power generation machine of the utility model with the characteristics of single-core power cables is: the extruded insulation layer consists of insulated wire cores on conductor, on the surface of single insulated wire cores the reinforced layer that is woven into by filament is set, and extrudes the formation external sheath layer at reinforced layer; 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 single-core power cables:
Conductor adopts the 5th class tinned copper wire that meets GB/T3956.
Insulating barrier is through extruding and forming through vapor crosslinking take silicon rubber, fluorosioloxane rubber or ethylene propylene diene rubber as material.
Reinforced layer adopts the braiding of polyamide fibre line to form, and count is 50-65%.
External sheath layer is through extruding and forming through vapor crosslinking take neoprene, chlorosulfonated polyethylene rubber or chlorinated polyethylene rubber as material.
Compared with the prior art, the utility model beneficial effect is embodied in:
