Abstract
The invention discloses a frostiness-resistant cable for wind power generation, which comprises a cable core, wherein, fillings are arranged 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 that are 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 -25 DEG C to -55 DEG C only.
Description
Technical field
The invention belongs to the power cable field, specifically is a kind of anti-severe cold used for wind power generation cable.
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.The low temperature wind energy power cable is widely used in the connection of wind power generation machine rotor or is used for connection of the inside and outside non-moving power supply of tower etc., 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, sheath easy of crack cause short circuit when being lower than-55 ℃, and the equipment that influences normally uses.
Summary of the invention
Technical problem to be solved by this invention provides a kind of excellent electrical properties, long service life, the used for wind power generation cable of the anti-severe cold of ability.
A kind of anti-severe cold used for wind power generation cable of the present invention comprises cable core, and its cable core is by stranded the forming of some insulated cores, and the gap in cable core is provided with filling, outside cable core, extrudes armour, and outermost layer extrudes oversheath.
Said insulated wire cores is by conductor and be coated on the outer insulating barrier of conductor and form.
Beneficial effect of the present invention is:
Conductor insulation of the present invention and sheath adopt the rubber mixture through improved formulations, excellent electrical properties, and long service life, minimum operating temperature can reach-65 ℃, and common used for wind power generation cable can only be between-25 ℃～-55 ℃.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of anti-severe cold used for wind power generation cable of the present invention comprises cable core, and its cable core is provided with filling 3 by stranded the forming of some insulated cores at cable core internal pore place, and outermost layer extrudes oversheath 4.Said insulated wire cores is by conductor 1 and be coated on the outer insulating barrier 2 of conductor 1 and form.
The invention provides a kind of thinking and implementation method of anti-severe cold used for wind power generation cable; Concrete application approach is a lot, and the above only is a preferred implementation of the present invention, should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be regarded as protection scope of the present invention.
