Abstract
The invention relates to a cable, and particularly relates to a high-voltage cable, which comprises multiple cable cores and an outer sheath. An insulated layer is arranged between the cable core and the outer sheath; a filling layer is arranged between the cable cores and the insulated layer; an elastic buffer layer is arranged between the insulated layer and the outer sheath; the elastic buffer layer comprises a flexible inner pad and a flexible outer pad; and a plurality of air bags are arranged between the flexible inner pad and the flexible outer pad. After the above structure is adopted, when the high-voltage cable is subjected to external impact, the elastic buffer layer between the insulated layer and the outer sheath can effectively buffer pressure from the outside, and the wire core can be well protected from being damaged. In addition, as the outer sheath adopts a hard plastic tube, the weight is light, and the wire core can be effectively prevented from being scratched.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of high-tension cable.
Background technology
High-tension cable is the one of power cable, refers to the power cable for transmitting between 10KV-35KV, is applied to the major trunk roads of electric power transfer more.Some high-tension cable needs to be embedded under earth's surface, can prevent the damage of other external force, but just needs the compressing of resisting high strength on ground like this.
China utility model specification CN202384036U discloses a kind of high-tension cable, comprise multiple main push-towing rope core, the surrounding of each main push-towing rope core is provided with multiple auxiliary cable core, multiple main push-towing rope core and auxiliary cable core around thereof are arranged at the inside of an oversheath, main push-towing rope core and be provided with insulation fill stratum between auxiliary cable core and oversheath; The profile of oversheath is a flat shoestring structure.Multiple main push-towing rope core of the present utility model and auxiliary cable core around thereof are fixed on the inside of oversheath by insulation fill stratum, can bear larger load.
Summary of the invention
The technical issues that need to address of the present invention are to provide the good high-tension cable of a kind of compressive property.
For solving above-mentioned technical problem, high-tension cable of the present invention comprises multiple cable core and oversheath, insulating barrier is provided with between described cable core and oversheath, packed layer is provided with between described cable core and insulating barrier, elastic cord breaker is provided with between described insulating barrier and oversheath, described elastic cord breaker comprises flexible interior pad and flexibility pads outward, and in described flexibility, pad and flexibility are provided with some air bag between padding outward.
Described oversheath is plastic conduit.
After adopting said structure, when high-tension cable is subject to external impact force, the elastic cord breaker between insulating barrier and oversheath effectively can cushion the pressure from the external world, and well protection core is not damaged.In addition, oversheath adopts plastic conduit quality light and can effectively prevent core to be scratched.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of elastic cord breaker of the present invention.
In figure: 1 is cable core, 2 is insulating barrier, and 3 is elastic cord breaker, and 4 is oversheath, and 5 is flexible outer pad, and 6 is flexible interior pad, and 7 is air bag, and 8 is packed layer
Embodiment
As shown in Figure 1, high-tension cable of the present invention comprises multiple cable core 1 and oversheath 4, is provided with insulating barrier 2 between described cable core 1 and oversheath 4, is provided with packed layer 8 between described cable core 1 and insulating barrier 2.Be provided with elastic cord breaker 3 between described insulating barrier 2 and oversheath 4, as shown in Figure 2, described elastic cord breaker 3 comprises flexible interior pad 6 and flexibility pads 5 outward, and in described flexibility, pad 6 and flexibility are provided with some air bags 7 between padding 6 outward.
Described oversheath 4 is plastic conduit.
