no. 1 approach

[0016] The first embodiment: please refer to Figure 1-2 , A waterproof and anti-twist cable for wind power generation, comprising an outer insulating layer 1, the thickness of the outer insulating layer 1 is 0.1-0.12mm, the surface of the outer insulating layer 1 is fixedly connected with rubber bumps 2, the number of rubber bumps 2 is No less than forty and equidistantly arranged on the surface of the outer insulating layer 1, the rubber bumps 2 can not only thicken the outer surface of the cable, but also effectively improve its anti-torsion degree and increase the insulation performance of the cable. An outer waterproof layer 3 is attached to the inner wall of the insulating layer 1, and a silica gel layer 4 is attached to the inner wall of the outer waterproof layer 3. The silica gel layer 4 has high corrosion resistance. When the wires and cables encounter corrosive liquids, they will Good protection effect, the thickness ratio between the outer insulating layer 1, the ou...

Abstract

The invention discloses a waterproof and twist-proof cable for wind power generation. The cable comprises an outer insulating layer; the surface of the outer insulating layer is fixedly connected withrubber protrusions; and an outer waterproof layer is adhered to the inner wall of the outer insulating layer; a silicone layer is adhered to the inner wall of the outer waterproof layer; and a filling layer is adhered to the inner wall of the silicone layer; a main conductive wire is arranged at the center of the inside portion of the filling layer; secondary conductive wires are arranged in portions, at the top and left and right sides of the main conductive, inside the filling layer; and the four secondary conductive wires are arranged to encircle the main conductive wire at the center. Themain conductive and the secondary conductive wires each comprise a copper core, wherein the copper core is formed by twisting 23 bundles of wires, and each bundle is formed by twisting 102 copper wires with a diameter of 0.2 mm. The waterproof and twist-proof cable for wind power generation is simple in structure, low in cost, effectively avoids occurrence of cable twisting-off or water seepage,can realize continuous conveying of electric energy, reduces cost of circuit setting and completely satisfies demands of usage.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, in particular to a waterproof and anti-twist cable for wind power generation. Background technique [0002] Wind power is the conversion of the kinetic energy of wind into electric energy. As a clean and renewable energy, wind energy has attracted more and more attention from all over the world. It converts the kinetic energy of wind into mechanical kinetic energy, and then converts mechanical energy into electric kinetic energy. This is wind power. Power generation. The principle of wind power generation is to use the wind to drive the blades of a windmill to rotate, and then increase the speed of rotation through a speed increaser to promote the generator to generate electricity. According to the current windmill technology, the breeze speed is about three meters per second. It can start to generate electricity. Wind power generation is forming a boom in the world, because wind power g...
