Abstract
The utility model discloses a cable for wind power generation. According to the cable, three conductors inside are twisted by tinned soft copper wires, and are arranged in a delta shape, wherein the outside of the three conductors are separately wrapped with an insulation layer respectively; the outside of the insulation layers of the three conductors are wrapped with a wrapping tape layer; the wrapping tape layer is made of a flame-retardant mesh oxygen insulation tape; a filling layer is arranged between the wrapping tape layer and the insulation layers; and the outside of the wrapping tape layer is wrapped with a protective sheath layer. The cable for wind power generation is simple in structure and convenient to product, has excellent electric insulation performance and good cable flexibility. According to the cable, improvement on the structure of the lapping layer of the cable is made, the wrapping tape layer is made of a flame-retardant mesh oxygen insulation tape and a chloroprene rubber (CR) is adopted to make the protective sheath, and therefore problems that the cable is too crispy to install and cannot be frequently twisted when a polyvinyl chloride insulation control cable is in an environment at a temperature of minus 45 DEG C can be solved.
Description
Technical field
The utility model relates to cable industry, is specifically related to a kind of cable for wind power generation.
Background technology
At present. the cable of China's wind power generation special use still is in the starting stage.Because the environment of wind power generation is abominable, blower fan is longer service life, and cable constantly rotates with blower fan, performance requirement to cable is higher, so China's wind energy cable is dependence on import always, and expensive, research and develop and the domestic wind energy cable that comes into operation extremely urgent, high-end wind energy cable production domesticization road is shouldered heavy responsibilities.
Wind energy cable mainly refers to apply to engine room inside, cabin and pylon top, the occasion of tower under casing change place is arrived in the pylon bottom.Its classification mainly contains flexible cable, power cable (fixedly laying and reverse two parts), control cables etc.The environmental quality of wind energy cable operation is long-term moving going in outdoor, and vertical unsettled setting up frequently reversed (driftage is to wind automatically), contact greasy dirt direct sunlight etc., and the marine wind energy cable also will prevent the corrosion of seawater simultaneously.Because the harshness of cable running environment and condition, so also very high to the requirement of wind energy cable, mechanical strength is high, anti-turns round (softness), vibration resistance and oil resistant, uvioresistant, the requirements such as seawater corrosion resistance.
The utility model content
The utility model provides a kind of cable for wind power generation of knowing clearly, and it is simple in structure, easy to use, has solved the polyvinyl chloride insulation control cables in subzero 45 ℃ of lower places, and the cable embrittlement can not be installed and frequent torsion problem.
Scheme of the present utility model is as follows: a kind of cable for wind power generation, three inner conductors are closed by zinc-plated soft copper skein silk and form, described three conductors are arranged in a triangle, described three conductors are enclosed with insulating barrier outward respectively, the insulating barrier outside of described three conductors is enclosed with belting layer, described belting layer adopts fire-retardant netted oxygen barrier band to consist of, and is provided with packed layer between described belting layer and the insulating barrier, and the described belting layer outside is enclosed with restrictive coating.
Described cross-sectional area of conductor is long-pending to be 1.5～300mm
2, stranded lay ratio is less than 10.
Described insulating layer material adopts inflaming retarding ethylene propylene rubber.
Described restrictive coating material adopts flexible neoprene.
It is magnesium hydroxide powder that described packed layer adopts material.
Of the present utility model simple in structure, easily manufactured, have good electrical insulation capability, the cable flexibility is good; Structure for the lapping layer of cable is improved, belting layer adopts fire-retardant netted oxygen barrier band to consist of, adopt simultaneously neoprene (CR) as sheath, solved the polyvinyl chloride insulation control cables in subzero 45 ℃ of lower places, the cable embrittlement can not be installed and frequent torsion problem; In addition, improve the cable pliability, in the situation that keep cable to have preferably pliability, improved the intensity of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of cable for wind power generation, three conductors 1, three conductors 1 all have several zinc-plated soft copper skein silks to close to form, three conductors 1 are arranged in a triangle, and three conductor 1 outer insulating barrier 2 outsides that are enclosed with respectively 2, three conductors 1 of insulating barrier are enclosed with belting layer 3, belting layer 3 adopts fire-retardant netted oxygen barrier band to consist of, be provided with packed layer 4 between belting layer 3 and the insulating barrier 2, it is 1.5～300mm that belting layer 3 outsides are enclosed with 5, three conductors of restrictive coating, 1 sectional area scope
2, stranded lay ratio is less than 10, and insulating barrier 2 materials adopt ethylene-propylene rubber, and restrictive coating 5 materials adopt neoprene, and it is magnesium hydroxide powder that packed layer 4 adopts material.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
