Description
Technical field
The utility model relates to a kind of cable, particularly a kind of novel low-smoke halogen-free flame retardant wind energy cable that is applied to wind power generation.
Background technology
Along with the enhancing of human environmental consciousness, huge transformation is also taking place in the world energy sources structure, is promptly changed to the sustainable new energy resources system based on regenerative resource by the fossil energy system.These new forms of energy comprise solar energy, wind energy, biomass energy, geothermal energy, oceanic energy etc.In these numerous new forms of energy, with fastest developing speed at present, commercialization is the most extensive, the most suitable economically, when the number wind power generations.The wind energy resources of China is very abundant, and the wind power generation market prospects are wide.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.Mineral resources such as Chinese coal and oil are petered out at present, wind power generation is one of generation mode of the most ripe, tool large-scale development of renewable energy source domain and business development condition, wind energy is a kind of cleaning, reproducible green energy resource simultaneously, for readjusting the energy structure, alleviate environmental pollution, realization sustainable development etc. important impetus is arranged.
The existing wind-powered electricity generation installation of China is about 500,000 kilowatts, speed with average annual 40% rises, the end of the year 2006, about 91 wind energy turbine set that the whole nation has been built up and built, only 2,600,000 kilowatts of installation total capacities, to rise to 100,000,000 kilowatts to the year two thousand twenty, account for the year two thousand twenty electric power install 1,000,000,000 kilowatts 10%, account for 5% of power station total amount.From the evolution of external wind power generation, to the year two thousand fifty, 100,000,000 kilowatts the installation that China's wind-powered electricity generation will be estimated by the year two thousand twenty rises to about 1,600,000,000 kilowatts installation.This is undoubtedly a signal energetically concerning the electric wire market of China, also be a huge market.At present, China almost is blank to the research and development as one of wind-powered electricity generation critical elements wind energy cable, and a large amount of high-end cable products need import, and this has also hindered the fast development of China's wind power generation.To being applied to the wind energy cable of wind power generation, disclosed Chinese patent ZL200720038451.X wind energy cable, its conductor adopts multiply to twist copper wire again, conductive surface has tin coating, the outer compound nonwoven cloth separator that is provided with of this layer, the insulating material of insulation surface is rubber composite 3GI3, squeezes rubber composite 3GM3 sheath outward.Wind energy cable in this patent has only been made single core wind energy cable, and often needs the cable of multicore in the practical application, and unshielded, the non interference of this kind wind energy cable, is not suitable for the power or the signal transmission that have anti-interference to require in the wind power generation; The insulating material 3GI3 rubber composite of wind energy cable in this patent, its flexibility and heat resistance are all lower, can not be applicable to the use occasion of being strict with.
The utility model content
Goal of the invention: the purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of low-smoke halogen-free flame retardant wind energy cable is provided.
Technical scheme: the utility model discloses a kind of wind energy cable, comprise the core that constitutes by conductor and the outer insulating barrier of conductor, wrapped fire-retardant belt outside the cable core that core is twisted into more than two strands, outside fire-retardant belt, be extruded with sheath, woven shield outside sheath extrudes external sheath layer outside screen.
In the utility model, preferably, described conductor is copper or tin-coated copper conductor.
In the utility model, preferably, described insulating barrier, sheath and external sheath layer are the polyether-type thermoplastic polyurethane material, thereby make cable possess fabulous pliability, low temperature flexibility, good resistance to wear and good weatherability.
In the utility model, preferably, described screen is copper wire or tinned copper wire, can make wind energy cable have good shielding properties.
In the utility model, preferably, described fire-retardant belt is a glass fiber tape, thereby realizes cable fire-retardant in using.
Beneficial effect: wind energy cable described in the utility model is simple in structure, the selection science, function admirable, insulation of the polyether-type thermoplastic polyurethane of its use or protective cover material have fabulous pliability, low temperature flexibility, good resistance to wear and good weatherability, can improve the durability and the useful life of cable greatly, can under harsh environmental conditions and under the special use occasion, use.
Description of drawings
Be illustrated as the cross section structure schematic diagram of 4 core wind energy cables of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in the figure, wind energy cable described in the utility model, on copper or tin-coated copper conductor 1, extrude single core insulation core that polyether-type thermoplastic polyurethane insulating barrier 2 constitutes, carry out stranded stranding by four eradication edge cores then and form cable core, a wrapped glass fiber flame retardant belt 3 outside cable core, on fire-retardant belt 3, extrude polyether-type thermoplastic polyurethane sheath 4, braiding copper wire or tinned copper wire screen 5 on sheath extrude polyether-type thermoplastic polyurethane external sheath layer 6 again on screen 5 then.
The utility model provides a kind of thinking and method of wind energy cable; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
