Abstract
The utility model discloses a low-temperature-resistant, torsion-resistant wind energy cable, which comprises a conductor, an isolating layer and an insulating layer. The wind energy cable has the following characteristics: a smooth band material is arranged outside the insulating layer, and an extruded sheath layer is arranged outside the band material. For a long cable vertically laid in an operation place, an additional reinforcing layer, which is made of woven flexible thin tined copper wires, is arranged outside the extruded sheath layer. The utility model notably increases the low-temperature-resistant and torsion-resistant properties of the wind-cooled cable of an auxiliary wind-energy power system and has the advantages of good bending resistance, ultraviolet resistance, wearability, tensile resistance and oil-resistant capability and good electric insulation and mechanical properties, thus increasing the use convenience, safety, reliability and service life of the cable, reducing the cost on the frequent replacement of cables and having good social and economic benefits.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of low-temperature torsion resistance wind energy cable of using applicable to wind power engineering and other low-voltage power supply place or control system.
Background technology
Pay attention to today of environmental protection, while global energy growing tension day by day people; Renewable Energy Development and raising efficiency of energy utilization become two importances of the sustainable development energy undisputedly; wherein wind energy is one of main path that fundamentally solves human kind sustainable development energy problem as a kind of pollution-free and reproducible green energy resource.As " rising industry " of containing present flourish vital, one of critical elements of wind-powered electricity generation industry---wind energy private cable technology is demanded research urgently.In view of the wind-powered electricity generation engineering-environment abominable, blower fan requires very long again service life, and cable need constantly rotate with blower fan at low temperatures, common cable is because deadly defects such as " anti-applied environment ability, safety and reliability are low, useful life is short " obviously can not satisfy the special instructions for use of wind-powered electricity generation engineering.In long rotary course, common cable can also can cause the breakage of insulating barrier because of wearing and tearing because heating cause rubber layer softening, thus the potential safety hazard of generation wind power generation.
The utility model content
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and a kind of wind energy cable that possesses performances such as excellent low-temperature torsion resistance characteristic and good antifriction, tension, anti-bending is provided.
Technical scheme: the utility model discloses a kind of low-temperature torsion resistance wind energy cable, comprise comprising successively from inside to outside and it is characterized in that conductor, separator, insulating barrier, outside insulating barrier, be provided with smooth band, outside band, be provided with sheath and extrude layer.
Extrude between the layer mutually adhesion and have certain slide relative in order to satisfy insulating barrier and sheath, extrude wrapped smooth low temperature resistant band between the layer at insulating barrier and sheath especially, promote slip thus.
In the utility model, preferably, for length vertical run operational site cable, in addition one deck heavy seal coat is set additionally outside sheath extrudes layer, this heavy seal coat adopts zinc-plated soft copper filament weaving manner to make.Make air-cooled cable have splendid anti-pulling force, rub resistance characteristic thus, it is greatly slow light to make air-cooled cable its each critical component in laying installation or long-time running process bear pulling force or mechanical damage degree, simultaneously more reversing of wide-angle can be arranged in the blower fan twist process, thereby reduce phenomenons such as air-cooled cable core is broken, cortex breaks at air-cooled cable.
In the utility model, preferably, recommending soft copper filament diameter scope is 0.10mm～0.20mm, has resistance to bend(ing) energy preferably to guarantee cable.
In the utility model, preferably, described conductor is to twist the conductor that forms again by the annealed copper filament.
In the utility model, preferably, described insulating barrier is made of anti--40 ℃ of low temperature second third glue or anti--50 ℃ of low temperature silicon rubber.Thereby increased the resistance to low temperature of whole air-cooled cable.
In the utility model, preferably, described sheath extrudes layer low temperature resistant-55 ℃ of polyurethane by wear-resisting, tension, endurance, oil resistant, fire resistance excellence and constitutes, and has improved the correlated performance of air-cooled cable thus.
Beneficial effect: the utility model has significantly improved the low-temperature torsion resistance characteristic that is applied to the air-cooled cable in the wind energy electric power corollary system, and has good anti-bending, UV resistant, antifriction, tension, fuel tolerance capability and good electric insulation and mechanical performance, the deadly defects such as " anti-applied environment ability; safety and reliability are low; useful life is short " that can effectively avoid common cable to exist usually, thereby significantly improved the ease of use of cable, security reliability and useful life, reduced simultaneously that the user frequently changes cable and the expense that takes place has good society, economic benefit.
Description of drawings
Be illustrated as the sectional view of the utility model cable.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in the figure; low-temperature torsion resistance wind energy cable described in the utility model; tighten separator 2, low temperature resistant second third glue or silicone rubber insulation layer 3 by soft copper filament multiple stranded conductor 1, conductor; increase the smooth low temperature resistant band 4 that insulating barrier 3 and sheath extrude sliding distance between the layer 5, the sheath that is made of low temperature resistant-55 ℃ polyurethane material extrudes layer 5 and is made up of the heavy seal coat 6 that zinc-plated soft copper filament weaves.
In the present embodiment, described soft copper filament diameter scope is 0.10mm～0.20mm.
The utility model provides a kind of thinking and method of low-temperature torsion resistance 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.
