Abstract
The invention discloses a free-hanging wind power cable, which comprises a cable core formed by twisting a plurality of wire cores. Each wire core consists of a conductor and an insulating layer outside the conductor; packing layers are arranged in the gaps in the middle of the cable core and outside the cable core; a steel wire rope with equal length with the cable core is arranged parallel to the cable core; and the outer surface of the steel wire rope and the outer surface of the packing layers are extruded together to form a whole jacket layer. According to the invention, the steel wire rope is arranged in parallel with the cable core and is used as a load bearing member, and in actual use, the breaking force of the steel wire rope is not less than three times the gravity of the hung cable. In such a way, the gravity of the cable and the inertia force of the cable in the swinging process are both born by the steel wire rope, so the torsion resistance of the cable is greatly improved and the service life of the cable is prolonged manyfold.
Description
?
Technical field
The present invention relates to a kind of power cable, specifically is a kind of free suspension type wind energy cable.
Background technology
Along with the pressure increase of energy and environment, clean reproducible new forms of energy and receive common concern this year, in various green energy resources; Wind energy is the regenerative resource that has a high potential, and China widelys popularize the wind-powered electricity generation construction at present, and wherein wind-powered electricity generation adding new capacity in 2011 is above 2,000 ten thousand kilowatts; Be the first in the world, and ascendant trend is year by year arranged, wind energy cable is as the corollary equipment of wind-powered electricity generation; Must satisfy anti-chill, anti-reversing, particular surroundings requirement such as anti-aging.Particularly the wind energy power cable hangs for a long time, often oscillates, and need bear a large amount of gravity for a long time, and the conductor of cable also can bear part gravity in this process, add for a long time to swing back and forth, and reverses, and conductor is easy to open circuit because of fracture.Possibly not reach the instructions for use in 20 years its useful life, in the wind-powered electricity generation running, just needs often to change cable, the increase that has brought great inconvenience and cost like this.
Summary of the invention
It is high that technical problem to be solved by this invention provides a kind of intensity, can bear the free suspension type wind energy cable of cable deadweight and swing inertia force.
A kind of free suspension type wind energy cable of the present invention; Comprise the cable core that is twisted into by some cores; Said core is made up of conductor and the outer insulating barrier of conductor; Gap and cable core in the middle of the cable core are provided with packed layer outward, and with the laterally arrange steel wire rope of an equal length of cable core, the packed layer outer surface of said steel wire rope outer surface and cable core extrudes jointly and forms a complete restrictive coating.
As improvement of the present invention, conductor preferably is adopted as the 5th kind of stranded conductor, and restrictive coating is preferably TPU (Thermoplastic polyurethanes, TPUE plastic cement) material.
Beneficial effect of the present invention:
Free suspension type wind energy cable of the present invention; With the cable core steel cable that laterally arranges; Steel wire rope is as load-carrying members, and the pull-off force of steel wire rope should be not less than 3 times that suspended cables is conducted oneself with dignity during actual the use, gets inertia force like this in the deadweight of cable and the swing process thereof and is all born by steel wire rope; The anti-torsion capacity of cable is greatly enhanced, and be multiplied useful life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; A kind of free suspension type wind energy cable of the present invention; Comprise the cable core that is twisted into by some cores, said core is made up of conductor 1 and the outer insulating barrier 2 of conductor, and wherein conductor 1 material is that the 5th kind of stranded conductor cable core middle gap and cable core are provided with packed layer 3 outward; With the laterally arrange steel wire rope 4 of an equal length of cable core, packed layer 3 outer surfaces of said steel wire rope 4 outer surfaces and cable core extrude jointly and form a complete TPU restrictive coating 5.
The above only is a preferred implementation of the present invention, should be pointed out 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, and these improvement also should be regarded as protection scope of the present invention.
