Abstract

The utility model discloses an outdoor tensile cable, which comprises a plurality of conducting wires, filling materials among the conducting wires, a lapping tape and an outer sheath. Each conducting wire consists of a plurality of conducting cores and an insulating layer which is extruded on the surface of the conducting cores. A reinforcing core which is made of aramid fiber yarns is inlaid in the center of the conducting cores. Each conducting core consists of a single flexible copper wire or a plurality of stranded flexible copper wires. The sectional area of the conducting core is 0.5mm<2> to 10 mm<2>. The number of the conducting cores is two to sixty-one. The insulating layers, the filling materials and the outer sheath are made of high molecular materials. The outdoor tensile cable has the advantages of high tensile strength and torsion resistance.

Description

The outdoor stretch-proof cable

Technical field

The utility model relates to a kind of used for wind power generation tension cable, is specifically related to a kind of reinforced high tensile used for wind power generation control cable.

Background technology

As the generation mode the most ripe, exploitation condition on the largest scale and commercialized development prospect of technology in the new forms of energy, the development speed of wind power generation attracts people's attention.Becoming as the used for wind power generation cable of wind power plant auxiliary products has the cable of huge market potential kind, by numerous cable enterprise's exploitations and put on market.The strengthening core of traditional control cable is a steel wire, in the reversed torsion process, broken easily or conductor by drawing-down, and traditional steel wire and strip armouring reinforced layer is soft inadequately, is difficult to bear the reversing of cable of used for wind power generation.

Summary of the invention

The purpose of this utility model is to provide a kind of tensile strength the high and anti-outdoor stretch-proof cable that reverses.

In order to achieve the above object, the technical solution of the utility model is: a kind of outdoor stretch-proof cable, comprise filler, twining package tape and oversheath between multiple conducting wires, multiple conducting wires, every lead is made of many conductor wire cores and the insulating barrier that is extruded in the conductor wire core surface, is provided with the wherein intracardiac strengthening core of being made by aramid yarn of embedding in the described conductor wire core.

Described conductor wire core is single annealed copper wire or many stranded annealed copper wires, and its cross section is 0.5mm2 to 10mm2.

Described conductor wire core core number is 2 core to 61 cores.

Described insulating barrier, filler and oversheath are that macromolecular material is made.

After adopting said structure, owing to be provided with the wherein intracardiac strengthening core of making by aramid yarn of embedding in the described conductor wire core, its tensile strength improves greatly, the softness characteristics of while aramid yarn, can not influence the bending of cable and travelling performance repeatedly, thereby satisfy tension, the torsional property of used for wind power generation control cable, effectively guarantee the reliable and stable operation of its connection device.

Fig. 1 is a structure cutaway view of the present utility model.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Referring to shown in Figure 1, a kind of outdoor stretch-proof cable, comprise filler 4, twining package tape 5 and oversheath 6 between multiple conducting wires 7, multiple conducting wires, every lead is made of many conductor wire cores 1 and the insulating barrier 3 that is extruded in conductor wire core 1 surface, is provided with the wherein intracardiac strengthening core of being made by aramid yarn 2 of embedding in the described conductor wire core 1.

Referring to shown in Figure 1, in order to satisfy used for wind power generation cable needs, the strengthening core 2 in described many conductor wire cores 1, the embedded electrical conductor core 1 and be extruded in the lead that insulating barrier 3 threes on conductor wire core 1 surface constitute and have three.

Referring to shown in Figure 1, in order to satisfy the different size needs, described conductor wire core 1 is single annealed copper wire or many stranded annealed copper wires, and its cross section is 0.5mm2 to 10mm2; Described conductor wire core 1 core number is 2 core to 61 cores.

Referring to shown in Figure 1, soft more in order to make this practical information, described insulating barrier 3, filler 4 and oversheath 6 are made for macromolecular material.

The utility model is the manufacture method by common cable, in conductor wire core 1 strand system process, the high strength aramid yarn is twisted simultaneously in the same way, and conductor wire core 1 is strengthened, and the cable tensile property is improved greatly, and torsional property also can improve greatly simultaneously.
