Abstract
The utility model discloses an ultraviolet-resistant power cable for wind power generation. The ultraviolet-resistant power cable comprises a cable core formed by two insulating cores arranged at intervals on a same plane. Each insulating core comprises a composite conductor and a rock wool band winding layer, a fiber braiding layer, an anti-tear insulating layer wrapped outside the composite conductor. The cable core is wrapped up by an ultraviolet-resistant oversheath layer, and a horizontal 8-shaped tensile cylinder is arranged in the ultraviolet-resistant oversheath layer. The tensile cylinder is braided with aramid fiber with a braiding density no less than 88%. The ultraviolet-resistant power cable is novel in structural design, and the tensile and warp-resistance performance of the cable is substantially improved through the fiber braiding layer and the horizontal 8-shaped tensile cylinder. Moreover, the ultraviolet-resistant power cable is resistance to acid, alkali, oil and ultraviolet and is warp-resistant as well to adapt to various severe weathers in wind power generation process.
Description
technical field:
The utility model relates to power cable, relates in particular to a kind of anti-ultraviolet power cable for wind energy generation.
background technology:
Along with the development of the communication technology, the application of cable is more and more extensive.Under so high ultraviolet index, the absorption ultraviolet ray that the insulating barrier of the electric insulation cable of common built on stilts generating use can be very fast, causes the fracture of insulating polymer, causes insulation cracking, has shortened the useful life of cable.
Constantly destroyed along with ozone layer, ultraviolet index also can be increasing, and the anti-ultraviolet property of cable for wind power generation is had higher requirement.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of anti-ultraviolet power cable for wind energy generation, there is acid and alkali-resistance, oil resistant, uvioresistant, warp resistance performance, to adapt to various atrocious weather environment in wind power generation process, and can there is Environmental Safety.
The technical solution of the utility model is as follows:
Anti-ultraviolet power cable for wind energy generation, comprise that two insulated wire cores spaced apart at grade form cable core, it is characterized in that: every insulated wire cores is coated with rock wool belt lapping layer, filament braid, tear-proof silicone rubber insulation layer formation by composite conductor and outside thereof, described cable core is coated with uvioresistant external sheath layer, in uvioresistant external sheath layer, be provided with the tension cylinder that is ∞ shape, tension cylinder adopts aramid fiber yarn braiding to form, and count is not less than 88%.
Described anti-ultraviolet power cable for wind energy generation, it is characterized in that: described composite conductor adopts 25 zinc-plated soft copper silks and 13 high carbon fiber wires to form through regular bundle strand/burst strand, stranded lay ratio is 12 ~ 18, and the filament diameter of zinc-plated soft copper silk is 0.16 ~ 0.35mm.
Described anti-ultraviolet power cable for wind energy generation, is characterized in that: the protective cover material of described uvioresistant external sheath layer is made up through mixing, extruding pelletization of modified polyvinyl resin, carbon black, stabilizer, light absorber.
The utility model has the advantages that:
The utility model structural design novelty, the structures such as the tension cylinder by filament braid, ∞ shape have improved the tension warp resistance performance of cable greatly, also there is acid and alkali-resistance, oil resistant, uvioresistant, warp resistance performance, to adapt to various atrocious weather environment in wind power generation process simultaneously.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
