Abstract
The utility model discloses an anti-distortion wind power electric cable, which is characterized in that the electric cable comprises a conductive body (1), a winding package reinforced layer (2), an insulation layer (3) and a sheathing layer (4), wherein the conductive body (1), the winding package reinforced layer (2), the insulation layer (3), and the sheathing layer (4) are sequentially distributed from the inside to the outside; and the conductive body (1) adopts the structure that a plurality of soft round copper stranded wires are twisted equidirectionally. The conductive body (1) of the wind power electric cable adopts the technology that a plurality of soft round copper stranded wires are twisted equidirectionally, so that the bending property and flexibleness of the electric cable can be ensured.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of warp resistance wind-force cable that can satisfy the special operational environment of used for wind power generation cable.
Background technology
The used for wind power generation wireline environment is special, and it is imperative requiring the wind energy cable of high-low temperature resistant, the contour performance of warp resistance.The structure of existing wind-force cable mainly adopts multiply to reestablish diplomatic relations, and conductive surface has this layer of tin coating to be provided with the compound nonwoven cloth separator outward, and the insulating material of insulation surface is a rubber composite, squeezes the rubber composite sheath outward.As: adopt low temperature (40 ℃ or-45 ℃ of silicone insulations) though the wind energy cable of rubber cable structure meets the flexible performance requirement that reverses wind energy cable, be subjected to environmental limitations during the short and low-temperature mounting of the relatively poor Acceptable life of the tear resistance of cable.Thereby the distortion performance of cable still can not satisfy used for wind power generation distortion performance requirement.
The utility model content
Technical problem to be solved in the utility model provides a kind of warp resistance wind-force cable with better distortion performance requirement.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of warp resistance wind-force cable, comprise conductor, wrapped reinforced layer, insulating barrier and restrictive coating, and described conductor, wrapped reinforced layer, insulating barrier and restrictive coating distribute from inside to outside successively; Described conductor is that the soft round copper stranded conductor of multiply is also with twisting together in the same way.
The insulating barrier of cable and restrictive coating adopt the double-layer coextrusion technology, improve the associativity between insulating barrier and the restrictive coating, and sheath adopts rubber can strengthen the antitorque commentaries on classics performance and the production efficiency of cable.
Conductor of the present utility model adopts the more soft soft round copper stranded conductor of (the 6th class conductor) multiply and uses stranded in the same way technology, and this structure has guaranteed the bending property and the flexibility of cable.Simultaneously, such structure also reduces the stranded diameter of rope-lay strand, makes that the soft round copper stranded conductor of multiply is tightr, thereby can reduce the cost of whole cable.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is the schematic cross-section of warp resistance wind-force cable of the present utility model.
Embodiment
As shown in drawings, a kind of warp resistance wind-force cable of the present utility model comprises conductor 1, wrapped reinforced layer 2, insulating barrier 3 and restrictive coating 4, and described conductor 1, wrapped reinforced layer 2, insulating barrier 3 and restrictive coating 4 distribute from inside to outside successively.
Conductor 1 adopts the soft soft round copper stranded conductor of (the 6th class conductor) multiply and uses stranded in the same way technology, this structure has guaranteed the bending property and the flexibility of cable, can also reduce the stranded diameter of rope-lay strand, make that the soft round copper stranded conductor of multiply is tightr, can reduce the cost of whole cable.
On the construction of cable, cable is optimized design, adopts technology, improve the quality of products multiply stranded in the same way tight rounding of soft round copper stranded conductor and soft technology.The technology of reinforced insulation layer 3 and restrictive coating 4 double-layer coextrusion technology makes it to satisfy and produces the used for wind power generation cable in batches, also can be used for the product scope of special cables such as Aero-Space.
The foregoing description limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
