Abstract
The invention relates to a cold and torsion resistant flexible cable for wind power generation. The single core cable is composed of a stranded conductor (1), acrylic yarn (2), a wrapping strip (3), an insulating layer (4) and an outer sheath (5); the stranded conductor (1) is formed by standing 7 soft steel wires (11) of 0.15-0.25mm into stranded wires (12) and stranding the 19 stranded wires (12) once again; after the periphery of the stranded conductor (1) is winded and wrapped by the wrapping strip (3), the insulating layer (4) is extruded and wrapped into an insulating wire core, and finally the outer sheath (5) is extruded and wrapped at the periphery of the insulating wire core; and peripheral gaps of the stranded wires (12) of all layers are filled with the acrylic yarn (2). In the invention, because the gaps of the stranded conductor are filled with the acrylic yarn (2), the cable core is filled with unvulcanized rubber strips so as to be integrated with the outer sheath (5), and the insulating layer (4) is made of ethylene-propylene rubber with excellent low-temperature performance and weathering performance, the cold and torsion resistance of the flexible cable is greatly improved, the flexible cable can not be broken down in five minutes at the voltage of 2.5U0, and the surface of the flexible cable can not crack at the temperature of 40 DEG C below zero after being subjected to torsion for 500 times.
Description
Technical field
The present invention relates to a kind of cold-resistant anti-cable that reverses, the cold-resistant anti-wind energy of reversing of particularly a kind of used for wind-energy power generation is used flexible cable.
Background technology
In numerous regenerative resources, wind power generation has safety, cleaning, aboundresources, inexhaustible, nexhaustible, is a kind of regenerative resource of perpetuity.
Along with developing rapidly of wind-powered electricity generation industry, expedited the emergence of demand to cable for wind power generation.
Cable for wind power generation; Because the extreme foul disease of its running environment; And cable will frequently reverse with blower fan; Particularly move in like-40 ℃ of environment at low temperature, the mechanical property of materials changes and still requires to have good warping property (low temperature distortion performance does not down descend), and is therefore very high to the cold-resistant anti-twisting property requirement of cable.Existing rubber sleeve flexible cable is owing to structural reason, and its flexibility, cold resistance and the anti-property turned round are all not good enough, can not satisfy the requirement that the used for wind-energy power generation rubber sleeve flexible cable frequently reverses.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, and provide the cold-resistant anti-wind energy of reversing of a kind of used for wind-energy power generation to use flexible cable.
Technical scheme of the present invention is: the cold-resistant anti-wind energy of reversing of a kind of used for wind-energy power generation is used flexible cable, and single-core cable is made up of stranded conductor, acrylics filament, twining package tape, insulating barrier and oversheath; After stranded conductor is twisted into strand by the soft copper tow of 7 0.15～0.25mm, 19 strands is twisted again form again; The stranded conductor periphery with twining package tape wrapped after; The insulating barrier that extrudes again becomes insulated wire cores; Insulating barrier adopts cryogenic property and the good ethylene-propylene rubber of weather resistance, extrudes oversheath again in the insulated wire cores periphery at last, and fill with acrylics filament the gap of every layer of strand periphery.
The further technical scheme of the present invention is: lay ratio is 14-15 times during the bundle strand.
The further again technical scheme of the present invention is: multiple strand adopts the ectonexine strand to identical, and internal layer lay ratio and outer lay ratio are 11-12 times.
Technical scheme of the present invention also can be: the cold-resistant anti-wind energy of reversing of a kind of used for wind-energy power generation is used flexible cable, and three-core cable is made up of stranded conductor, acrylics filament, twining package tape, insulating barrier, oversheath and rubber packing; After stranded conductor is twisted into strand by the soft copper tow of 7 0.15～0.25mm, 19 strands is twisted again form again; Acrylics filament is filled in the gap of every layer of strand periphery; The stranded conductor periphery with twining package tape wrapped after; The insulating barrier that extrudes again becomes insulated wire cores; Insulating barrier adopts cryogenic property and the good ethylene-propylene rubber of weather resistance, at last three insulated core strandings is extruded oversheath after stranded, and the cable core gap is with the rubber packing filling of not vulcanizing.
The further technical scheme of the present invention is: lay ratio is 14-15 times during the bundle strand.
The present invention's technical scheme further is: multiple strand adopts the ectonexine strand to identical, and internal layer lay ratio and outer lay ratio are 11-12 doubly.
The further again technical scheme of the present invention is: lay ratio was 11-13 times when stranding was stranded.
The present invention compared with prior art dwindles bundle strand and is twisted into the lay ratio of cable stranded conductor again owing to adopted, bundle strand strand to the strand that is twisted into the cable stranded conductor again on the contrary; Strand twists the ectonexine strand again to identical, and increase stranded conductor space adopts acrylics filament to fill, and cable core is filled and adopted the filling of half finished rubber bar to make cable core become as a whole with sheath; Cryogenic property and the good technical measures such as ethylene-propylene rubber of weather resistance are adopted in insulation; Greatly improved the cold-resistant anti-twisting property of cable, through torsion test, positive and negative three weeks are for once; 3600 times cable surface does not have cracking, 2.5U
0Press not puncture in 5 minutes, the adapted cold resistant rubber does not have cracking at-40 ℃ of 500 cable surfaces.
Below in conjunction with accompanying drawing and embodiment detailed content of the present invention is further described.
