Abstract
The utility model discloses a frostiness-resistant cable for wind power generation, which comprises a cable core, wherein, fillings are provided in a gap in the cable core; the outermost layer of the cable core is wrapped with an outer sheath in an extruded manner; a plurality of wire cores are twisted to form the cable core; and each insulation wire core comprises a middle conductor and an insulation layer, and the middle conductor is coated with the insulation layer. The conductor insulation and the sheath in the frostiness-resistant cable adopt rubber mixtures formed through an improved formula, the electrical performance is excellent, the service life is long, the minimum operating temperature can reach minus 65 DEG C, and the operating temperature of a common cable for wind power generation can range from minus 25 DEG C to minus 55 DEG C only.
Description
Technical field
The utility model belongs to the power cable field, specifically a kind of anti-severe cold cable for wind power generation.
Background technology
In today of global energy growing tension, country constantly increases the demand of regenerative resource, and therefore as the low-temperature wind-energy power cable of wind power plant auxiliary products, becoming has the cable of huge market potential new varieties, and exploitation is also invested market.Low-temperature wind-energy power cable is widely used in the connection of wind power generation machine rotor or is used for the connection etc. of the inside and outside non-moving power supply of tower, has solved the hidden danger of equipment safety operation, has upgraded environmental benefit, has brought economic benefit.The shortcoming of existing low-temperature wind-energy power cable is: insulation when being lower than-55 ℃, sheath easily cracking cause short circuit, and the equipment that affects normally uses.
The utility model content
Technical problem to be solved in the utility model provides a kind of excellent electrical properties, long service life, the cable for wind power generation of the anti-severe cold of energy.
A kind of anti-severe cold cable for wind power generation described in the utility model comprises cable core, and its cable core is by stranded the forming of some eradication edge cores, and the gap in cable core is provided with filling, extrudes armour outside cable core, and outermost layer extrudes oversheath.
Described insulated wire cores is by conductor and be coated on the outer insulating barrier of conductor and form.
The beneficial effects of the utility model are:
The utility model conductor insulation and sheath adopt the rubber mixture through improved formulations, excellent electrical properties, and long service life, minimum operating temperature can reach-65 ℃, and common cable for wind power generation can only be between-25 ℃～-55 ℃.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of anti-severe cold cable for wind power generation described in the utility model comprises cable core, and its cable core is provided with filling 3 by stranded the forming of some eradication edge cores at cable core internal pore place, and outermost layer extrudes oversheath 4.Described insulated wire cores is by conductor 1 and be coated on the outer insulating barrier 2 of conductor 1 and form.
The utility model provides a kind of thinking and implementation method of anti-severe cold cable for wind power generation; concrete application approach is a lot; the above only is 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 improvement, these improvement also should be considered as protection range of the present utility model.
