Description
Technical field
The utility model relates to a kind of wind power cable, and it is mainly used in rated voltage 0.6/1kV and the generating of following blower fan, belongs to field of cable technology.
Background technology
Wind energy cable is due to the particularity of its instructions for use and environment for use etc., therefore having specific characteristics for wind energy cable can requirement, as enough mechanical strengths will be had, good resistance to twisting property, also to have many requirements such as oil resistant, weathering, salt spray resistance, if also certain cold tolerance will be had at cold district wind energy cable.
A kind of wind power cable used when exporting for wind power generation electro-mechanical force is had in wind energy cable, wind power cable also has certain requirement, particularly to resistance to twisting property, oil resistance (as: No.2 of resistance to ASTM, gear oil, hydraulic oil), Halogen to mechanical strength, electric property, resistance to twisting property etc.This is because wind power cable flexibility is better, tension and anti-seismic performance better, resistance to twisting property is better, then the useful life of wind power cable can be longer.Separately, cable works for a long time in airtight tower cylinder, and the performance quality of cable directly affects the normal operation of Wind turbines; as oil resistance, Halogen; cable non-corrosiveness gas is overflowed, and can not corrode parts in cabin, protect unit equipment, controls unit cost further.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides the wind power cable of a kind of resistance to torsion, oil resistant, Halogen, its rated voltage 0.6/1kV and following.
For realizing above-mentioned technical purpose, the utility model by the following technical solutions:
A kind of rated voltage 0.6/1kV and following wind power cable, a conductor in the middle of it, wherein: outside described conductor, be surrounded with separator, outside separator, extrude the insulating barrier that second third insulation compound is formed, outside insulating barrier, extrude the oversheath that Halogen cross-linking type EVA material is formed.
Further, described separator is electric isolution ply of paper, polyester layer or nonwoven layer.
Further, described conductor is tin-coated copper monofilament or naked copper monofilament.
Another kind of rated voltage 0.6/1kV and following wind power cable, at least two conductors in the middle of it, wherein: outside described every root conductor, extrude the insulating barrier that second third insulation compound is formed, described conductor and insulating barrier form core, center-filled bar in the middle of the core of multiple circumference arrangement, the core gap of multiple circumference arrangement is provided with filler, multiple core, center-filled bar and filler are twisted into cable core, the outer wrapped separator of cable core, extrudes the oversheath that Halogen cross-linking type EVA material is formed outside separator.
Further, described center-filled bar is filament.
Further, described filler is the filler that Halogen cross-linking type EVA material is formed.
Further, described separator is electric isolution ply of paper, polyester layer or nonwoven layer.
Further, described conductor is tin-coated copper monofilament or naked copper monofilament.
After adopting technique scheme, the utility model has following beneficial effect:
Have employed special conductor structure, particularly copper conductor, while ensureing conductivity, improve whole cable anti-torsion performance.The setting of separator, increases the Relative sliding between conductor and insulation, or the Relative sliding between core and insulation, thus improves the anti-torsion ability of cable.
Insulating barrier adopts special soft second third insulation compound, makes the highest Long-term service temperature of this cable bring up to 90 DEG C, meets-40 DEG C of environmental requirements simultaneously; Second third insulate the toxic components such as not leaded, halogen, meets environmental requirement.
For multicore structure, core gap adopts environment-friendly type cross-linking type EVA material as filling, adopts packing, ensure that sheathing uniformity on the one hand, and when can use under-40 DEG C of low temperature, cable still has good flexibility, slipping property in the middle of core; On the other hand, the resistance to twisting property of cable is improved.
Cross-linking type EVA, Chinese: ethylene-vinyl acetate copolymer, is formed primarily of appropriate EVA material, conductive black, crosslinking agent, lubricant and antioxidant.Cross-linking type EVA material meets low cigarette, Halogen, fire-retardant, resistance toly to turn round, resistance to wet goods requirement.
By the implementation of above measure, make the utility model have excellent flexibility, splendid pull resistance and superior resistance to gesture torsion, be applicable to the occasion frequently reversed and move back and forth.
