Abstract
The invention discloses a power cable for wind power generation, and relates to the technical field of manufacturing of cables. The power cable for the wind power generation comprises three insulated wire cores, wherein a polypropylene wrapping tape layer, an aramid fiber woven bearing strengthening layer and a chloroprene rubber outer sheath layer are sequentially arranged on the outer side of the three insulated wire cores; a filled layer is arranged between each insulated wire core and the polypropylene wrapping tape layer; each insulated wire core comprises an annealed tin-plated soft copper wire bundle stranded conductor which is wrapped with a modified ethylene propylene rubber insulated layer. The power cable for wind power generation has excellent performance of torsion resistance, high and low temperature resistance, flame retarding, oil resistance, corrosion resistance, heat resistance, ozone resistance, ultraviolet protection and the like.
Description
Technical field
The present invention relates to the manufacturing technology field of cable, relate in particular to a kind of power cable for wind energy generation.
Background technology
In recent years, China greatly develops new forms of energy, the New Energy Industry of wind power generation and most Commercial Prospect the most ripe as technology, be developed rapidly, installed capacity of wind-driven power every year on average with more than 20% speed increase, to " the 12 " end of term, 100,000,000 kilowatts will be reached.Because wind power generation unit generally all build offshore islands in, outlying mountain area and scarcely populated prairie, accept " baptism " of strong wind and heavy rain and tanning by the sun that The sun is shining fiercely year in year out, because running environment is severe, higher to the technical requirement of cable, the resistance to torsion cable of blower fan, cable can with the continuous forward of blower fan and reverse rotation, requirement cable is soft, has higher tensile strength, resistance to torsion, high-low temperature resistant, UV resistant (weatherability), resisting salt fog corrosion, numerous technical indicator such as fire-retardant again.And the wind energy cable in prior art in the market can not meet these requirements well on properties.
Summary of the invention
The present invention is the weak point for avoiding existing for above-mentioned prior art, provides a kind of power cable for wind energy generation possessing the performance such as excellent resistance to torsion, high-low temperature resistant, fire-retardant, oil resistant, corrosion resistant, heat-resisting, resistance to ozone, antiultraviolet.
The present invention includes three strand insulation cores, outside described three strand insulation cores, set gradually polypropylene belting layer, aramid fiber braiding load-bearing reinforced layer and neoprene rubber external sheath layer; Between three strand insulation cores and polypropylene belting layer, packed layer is set; Insulated wire cores described in every root comprises number annealing zinc-plated soft copper tow strand conductor respectively, outside number annealing zinc-plated soft copper tow strand conductor, wrap up the ethylene propylene rubber insulated layer of modification.
Compared with prior art, beneficial effect of the present invention mainly contains:
1, conductor thread core of the present invention adopts some radicals to anneal zinc-plated soft copper silk, adopts the mode of multiple strand stranded again, ensure that cable has good warp resistance and softness after first Shu Hecheng strand.
2, insulating barrier of the present invention adopts modification ethylene-propylene rubber material, has excellent electrical insulation capability and corona-resistance property, also has weather, resistance to ozone simultaneously.The characteristics such as heat-resisting, acid and alkali-resistance, and made of soft.
3, the present invention arranges load-bearing reinforced layer, ensure that it has good drawing-resistant function on the one hand, on the other hand in cable twist process, enhance the Relative sliding between cable core and outer jacket, decrease the frictional force between cable core and outer jacket, be conducive to increasing the service life.
4, the present invention the adopts sheath material that is material with neoprene rubber, has fire-retardant, oil resistant, heat-resisting, resistance to combustion, resistance to daylight, resistance to ozone, acid and alkali-resistance and good physical and mechanical properties, improves the resistance to environment capacity of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes three strand insulation cores 1, outside three strand insulation cores 1, set gradually polypropylene belting layer 2, aramid fiber braiding load-bearing reinforced layer 3 and neoprene rubber external sheath layer 4; Between three strand insulation cores 1 and polypropylene belting layer 2, packed layer 5 is set; Every root insulated wire cores 1 comprises number annealing zinc-plated soft copper tow strand conductor 6 respectively, outside number annealing zinc-plated soft copper tow strand conductor 7, wrap up the ethylene propylene rubber insulated layer 7 of modification.
