Abstract
The utility model relates to a cable, in particular to a cold-resistant distortion-resistant flexible cable for wind-driven power generation, which comprises a cable conductor. The flexible cable is characterized in that an isolating layer is wrapped on the outer layer of the cable conductor, an insulating layer made of ethylene propylene rubber is sleeved on the outer portion of the isolating layer, and an outer sheath sleeved on the outer layer of the insulating layer is made of polyurethane. The cold-resistant distortion-resistant flexible cable has the advantages of resistance to low temperature, difficult cracking and distortion on the surface of the cable, long service life and the like.
Description
Technical field
The utility model relates to a kind of cable, especially relates to the anti-severe cold warp resistance of a kind of used for wind power generation flexible cable.
Background technology
As everyone knows, the used for wind power generation cable is applicable on the wind-driven generator.Formerly domesticly can only produce cold-resistant (40 ℃) the warp resistance flexible cable of used for wind power generation, cable is minimum can only be-40 ℃ of following operate as normal, and the private cable that present wind power plant is used, require cold-resistant (55 ℃) warp resistance, so conventional used for wind power generation cable has been not suitable for using, insulation and sheath can ftracture through distortion under severe cold, influence the useful life of cable.
The cable of traditional structure exists following defective and deficiency: the cold-resistant warp resistance flexible cable of the used for wind power generation of domestic production at present, used insulation and sheath material mainly are that silicon rubber, ethylene-propylene rubber etc. can only satisfy-42 ℃ of following operate as normal, can not satisfy under severe cold (55 ℃) condition, 2000 cycles are reversed, cable surface flawless and twisted phenomena, behind the cable process low temperature bend test, sheath and insulating surface flawless.
Summary of the invention
The utility model mainly is at the above-mentioned technical problem of existing in prior technology, provides a kind of low temperature resistant weak effect, cable surface to be prone to the short anti-severe cold warp resistance of used for wind power generation flexible cable of crackle and distortion, useful life.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the anti-severe cold warp resistance of a kind of used for wind power generation flexible cable, comprise cable conductor, it is characterized in that described cable conductor skin is surrounded with separator, described separator outer cover is provided with the insulating barrier that adopts ethylene-propylene rubber to make, described insulating barrier skin is arranged with oversheath, and described oversheath adopts the polyurethane manufacturing.Satisfy anti-reverse and the principle of low temperature resistant requirement is: insulating barrier adopts modification ethylene propylene rubber insulation material (composition: ethylene-propylene rubber: butadiene rubber is 85:15, adds 2-4 part coupling agent); Sheath adopts a kind of anti--55 ℃ polyurethane jacket cable material, and it is short that low temperature resistant weak effect, cable surface are prone to crackle and distortion, useful life.
As preferably, described cable conductor is a flexible conductor.Cable conductor adopts 5 class flexible conductors, take to be not more than the pitch of 25 times of strand external diameters at bundle strand line, outermost layer dextrad when twisting again, and adjacent layer strand is on the contrary, outermost layer tangles the tool ratio again less than 14 times, inferior outer pitch multiple is a bit larger tham outermost layer, more to the internal layer time apart from multiple greater than adjacent outer field pitch multiple, so cable is soft and can move.
Therefore, the utlity model has low temperature resistant weak effect, cable surface and be prone to characteristics such as crackle and distortion, useful life is short.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1, the anti-severe cold warp resistance of a kind of used for wind power generation flexible cable comprises cable conductor 1, the cable conductor skin is surrounded with separator 2, the separator outer cover is provided with the insulating barrier 3 that adopts ethylene-propylene rubber to make, and the insulating barrier skin is arranged with oversheath 4, and oversheath adopts the polyurethane manufacturing.Cable conductor is a flexible conductor.Cable conductor adopts 5 class flexible conductors, take to be not more than the pitch of 25 times of strand external diameters at bundle strand line, outermost layer dextrad when twisting again, and adjacent layer strand is on the contrary, outermost layer tangles the tool ratio again less than 14 times, inferior outer pitch multiple is a bit larger tham outermost layer, more to the internal layer time apart from multiple greater than adjacent outer field pitch multiple, so cable is soft and can move.
Satisfy anti-reverse and the principle of low temperature resistant requirement is: insulating barrier adopts modification ethylene propylene rubber insulation material (composition: ethylene-propylene rubber: butadiene rubber is 85:15, adds 2-4 part coupling agent); Sheath adopts a kind of anti--55 ℃ polyurethane jacket cable material, and it is short that low temperature resistant weak effect, cable surface are prone to crackle and distortion, useful life.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
