Abstract
The utility model discloses a high-strength and tensile cable used for wind power generation. The high-strength and tensile cable used for the wind power generation comprises a conductor located in the center of the cable, and an insulating layer and an inner protection layer which are extruded on the outside of the conductor orderly. An aramid yarn is braided on the outside of the inner protection layer, an outer protection layer is extruded on the outside of the aramid yarn, and the conductor is formed by twisting a plurality of annealed copper wires in the same direction. The cable of the utility model uses the aramid yarn to substitute for a metal strengthening layer in the prior art, thereby guaranteeing the tensile property of the cable while reducing the self-weight of the cable, and reducing the production cost and erection difficulty of the cable. The conductor is based on the same-direction twisting mode, the flexibility and service life of the cable are improved, and the safety during the use process is guaranteed.
Description
Technical field
The utility model relates to a kind of cable, especially a kind of high-strength tensile cable for wind power generation.
Background technology
Existing used for wind power generation single-core cable has two kinds of high pressure and low pressure, and wherein the general own wt of used for wind power generation high voltage single-core cable is larger, for maintaining good tensile property and improving the amount of damming of conductor, also will in its structure, increase copper strip shielding layer.Certainly will increase like this cable deadweight, also increased the production cost of cable simultaneously and set up difficulty.And used for wind power generation low voltage single core cable, because its electric pressure is not high, the elastomeric material using is fewer than used for wind power generation high voltage single-core cable, therefore lightweight, it has interior and outer structure is conductor, separator, insulating barrier, restrictive coating, and the stranded mode of conductor is not all for stranded in the same way.Because the conductor employing of cable is not stranded in the same way, so the softness of whole cable is poor, cannot meet and specifically set up and user demand.
Utility model content
The utility model is to provide a kind of high-strength tensile cable for wind power generation, to solve the technical problem that in prior art, used for wind power generation single-core cable own wt is large, production cost is high and softness is poor.
For solving above technical problem, high-strength tensile cable for wind power generation described in the utility model, comprises being positioned at the conductor at center, being extruded in insulating barrier and the sheath outside conductor successively, described sheath weaves aramid yarn outward, and aramid yarn extrudes outer jacket outward.
Described conductor is by many annealed copper wires stranded forming in the same way.
Described insulating barrier and sheath adopt the mode of double-layer coextrusion to be extruded in outside conductor.
The utility model beneficial effect is, thereby employing aramid yarn replaces metal shielding in prior art to alleviate cable deadweight in the tensile property that guarantees cable, has reduced the production cost of cable and has set up difficulty; Conductor has adopted stranded in the same way mode, improves flexibility and the useful life of cable, has guaranteed the safety in use procedure.
In order to improve the triangular compactness of insulating barrier, sheath and conductor and protection effect, insulating barrier and sheath can also adopt the mode of double-layer coextrusion to be extruded in outside conductor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, high-strength tensile cable for wind power generation of the present utility model comprises respectively conductor 1, insulating barrier 2, sheath 3, virtue wheel yarn 4, outer jacket 5 from inside to outside.Insulating barrier 2 and sheath 3 adopt the mode of double-layer coextrusion to be extruded in outside conductor 1, the outer braiding aramid yarn 4 of sheath 3, the outer outer jacket 5 that extrudes of aramid yarn 4.Conductor 1 adopts soft copper material, by many annealed copper wires stranded forming in the same way.
Above-mentioned is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement and adjustment, these improvement and adjustment also should be considered as protection range of the present utility model.
