Abstract
The invention relates to a novel wind power cable, which consists of a conductor, an insulator, a filler, a cabled tape and an outer sheath. The inner core of the conductor is of a wire bundle structure made of annealed copper wires, and the outer layer of the conductor is formed by tinned copper braiding; ethylene-propylene rubber is used as the insulation layer of the cable; and the filler adopts a neoprene material, thereby effectively solving the problems of the low temperature resistance, ultraviolet resistance, smog corrosion resistance and torsion resistance of the cable. The cabled tape is arranged outside of the filler and between the filler and the sheath, and forms a non-woven cloth insulation layer. The invention has the advantages of excellent tensile strength, twisting resistance, bending resistance, lower temperature resistance, ultraviolet resistance, smog corrosion resistance and torsion resistance.
Description
Technical field the invention belongs to the technical field of power cable, relates to a kind of novel wind power cable specifically.
Background technology wind-driven generator for many years shows, wind-driven generator what will solve emphatically is reliability and life-span.The load that wind-driven generator faced unlike communication and computer equipment, it must guarantee use constantly all the year, bear again expose to the sun and rain, the weather is cold and the ground is frozen, service conditions is very abominable, very big at China's wind energy content, distribute wide, but the region is wide, the wind scale difference is bigger, north-south climate difference is also bigger, northern area requires ability-30 ℃ and following low temperature, and the coastal area has just required to possess anti-salt fog, prevent functions such as damp and hot, mould proof, so also higher to the requirement of wind energy cable.
Summary of the invention is in order to overcome above-mentioned deficiency, and main purpose of the present invention aims to provide a kind of anti-curved, high-low temperature resistant, salt spray resistance, softness movably, and can provide practicality higher a kind of novel wind power cable.
The technical solution used in the present invention: it is conductor, insulator, filler, stranding band, oversheath composition that a kind of novel wind power cable is divided into from the inside to the outside.The inner core of conductor is the thread synnema structure of annealed copper, and skin is formed by the tin-coated copper braiding; Use the insulating barrier of ethylene-propylene rubber as cable; Filler is to adopt chloroprene rubber material, has solved anti-low temperature, UV resistant, the burn into of the anti-smog resistance against torsion of cable effectively.
Be the stranding band outside described filler and between the sheath, i.e. nonwoven fabrics separator.
The present invention can stand-40 ℃～90 ℃ cold performance test; Oil resistant and salt tolerant alkalescence can wait, be particularly suitable for environment badly, use for a long time under the occasion of low temperature and serious wear.
The highest long-term permission working temperature of cable: 85 ℃;
Cable lay temperature :-35 ℃, need not to heat in advance, cable is not limited by drop;
Water resistance radially: insulating surface does not have moisture, and the insulation resistance rate of change is not less than 5%;
Vertical geomantic omen performance: under the water of regulation, after 7 days, water immerses the cable inner length and is not more than 1.5m.
Because the present invention adopts second third insulator and neoprene inserts, has solved anti-low temperature, UV resistant, the burn into of the anti-smog resistance against torsion of cable.Under-45～110 ℃ ambient temperature, can arbitrarily bend and twist, do not ftracture, and wear-resisting, acid-alkali-corrosive-resisting, anti-atmospheric aging.
The present invention has good tension, anti-twist and bend resistance performance, tensile strength 28MPa, and elongation 725% is highly suitable for the adverse circumstances of wind power generation, and it is very long that blower fan requires service life, and cable is with the rotating condition of blower fan.Utilize the good bending and the torsion characteristic of the second third gummed neoprene, realize technical support wind energy cable.

Embodiment
In the simplified schematic diagram of a kind of novel wind power cable shown in Figure 1, being divided into from the inside to the outside is conductor 1, insulator 2, filler 3, stranding band 4, oversheath 5 compositions.The inner core of conductor 1 is the thread synnema structure of annealed copper, and skin is formed by the tin-coated copper braiding; Use the insulating barrier 2 of ethylene-propylene rubber as cable; Filler 3 is to adopt chloroprene rubber material, has solved anti-low temperature, UV resistant, the burn into of the anti-smog resistance against torsion of cable effectively.Outside described filler 3 and between the sheath 5 is stranding band 4, i.e. the nonwoven fabrics separator.
The present invention can stand-40 ℃～90 ℃ cold performance test; Oil resistant and salt tolerant alkalescence can wait, be particularly suitable for environment badly, use for a long time under the occasion of low temperature and serious wear.The highest long-term permission working temperature of cable: 85 ℃; Cable lay temperature :-35 ℃, need not to heat in advance, cable is not limited by drop; Water resistance radially: insulating surface does not have moisture, and the insulation resistance rate of change is not less than 5%; Vertical geomantic omen performance: under the water of regulation, after 7 days, water immerses the cable inner length and is not more than 1.5m.
Because the present invention adopts second third insulator 2 and neoprene inserts 3, has solved anti-low temperature, UV resistant, the burn into of the anti-smog resistance against torsion of cable.Under-45～110 ℃ ambient temperature, can arbitrarily bend and twist, do not ftracture, and wear-resisting, acid-alkali-corrosive-resisting, anti-atmospheric aging.
