Description

Wind energy cable

Technical field

The utility model relates to a kind of wind energy cable.

Background technology

21 century, countries in the world have all turned one's attention to the clean energy resourcies such as nuclear energy, photovoltaic, wind energy, and the exploitation of renewable resource has become majority state energy strategy.According to incompletely statistics, China mainland and inshore can utilize nearly 1,000,000,000 kW of wind energy resources, China's " planning of regenerative resource Long-and Medium-term Development " points out, the year two thousand twenty China wind-powered electricity generation total installation of generating capacity reaches 3,000 ten thousand kW, and 2013-2020 is still the gold period of being well worth doing.Also just urged the development of the supporting cable industry of wind power generation simultaneously, as for the control cables in wind-power engine room and tower cylinder, signal cable, warp resistance power cable etc., because of wind field bad environments, and power cable swings and distortion with impeller, so cable for wind power generation General Requirements is higher, as required low temperature resistant, oil resistant, warp resistance, weather, UV resistant, acid and alkali-resistance etc.In recent years, a lot of wind energy cable limits because of service condition, the cable that great majority adopt rubber-covered and sheath to make, but because of rubber cable complex process, manufacturing cost higher and not easily make and possess environmental protection flame retardant fire protecting performance and be subject to a lot of restriction.So, develop a kind of easy processing, there is mechanical performance required by wind-powered electricity generation cable and the wind energy generating plant cable of flame-proof environmental protection can be made according to environment for use very urgent.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind ofly has good low temperature resistant and resistance to wear, and fatigue durability, weather-resistant performance, microbial resistance energy, to oil product, chemicals, there is fabulous corrosion resistance, anti-torsion performance and bending property excellence, lay temperature and serviceability temperature is wide in range, flame-proof environmental protection and the simple wind energy cable of production technology.

For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of wind energy cable, comprise conductor and be extruded in the insulating barrier outside conductor, described conductor and insulating barrier are combined into insulated wire cores, the outer overlap of described insulated wire cores is surrounded with halogen-free flameproof band, is provided with metal wire knitted screen, is extruded with oversheath outside metal wire knitted screen outside halogen-free flameproof band, described conductor is oxygen-free copper core, and insulating barrier is thermoplastic vulcanised elastomer.

Insulating barrier described in the utility model is also provided with packed layer outward, and packed layer is cotton cord or glass fiber rope.

Conductor described in the utility model twists bare copper wire by composite bundle or tinned copper wire forms.

Halogen-free flameproof band described in the utility model adopts the overlapping lapping structure of halogen-free flameproof band, and the wrapped rate of putting up is not less than 20%.

Metal wire knitted screen described in the utility model adopts high density proof copper-wire braided, and count is not less than 80%.

Insulated wire cores described in the utility model is single cored structure.

Insulated wire cores described in the utility model is the multicore structure of 2 cores, 3 cores, 4 cores, 5 cores or 19 cores.

The utility model compared with prior art, adopts during conductor synnema and restraints strand in the same way, cable conductor can be made more soft relative to common cable conductor, and insulating barrier and restrictive coating adopt thermoplastic vulcanised elastomer material, and physics and chemistry combination property is good; Process simple, common plastics extruder can be extruded, and has the advantages that mobility is high, shrinkage is little.
