To achieve these goals, the technical solution of the utility model is as follows, high-strength cable, it is characterised in that described High-strength cable includes at least four cores, is provided with drainage thread in four cores, high-strength cable from inside to outside according to It is secondary to be provided with wearing layer, armor and restrictive coating, filler is provided between the core, the filler is wrapped up for steel wire Cordage；

Anti-wear performance is high, the cordage wrapped up by steel wire, the whole intensity of cable is strengthened, additionally, steel wire outer surface Nylon layer can be also coated with, further makes cable wear-resistant, extend the service life of cable.

Used as a kind of improvement of the present utility model, the core includes conductor, insulating barrier and screen layer, the number of the conductor Amount is at least one.

Used as a kind of improvement of the present utility model, the conductor uses tinned copper conductor, and the insulating barrier is poly- using crosslinking Vinyl material is made.

Used as a kind of improvement of the present utility model, the screen layer is formed by mica tape braiding.

Used as a kind of improvement of the present utility model, the middle setting of the high-strength cable has cylindrical wear-resisting support.

Used as a kind of improvement of the present utility model, the thickness of the armor is 0.1-0.25mm.

Relative to prior art, advantage of the present utility model is as follows, and 1）Whole Technical Design is ingenious, and simple structure is tight Gather, 2）High-strength cable described in the technical scheme has good resistance to elevated temperatures and anti-wear performance, and at high temperature It is difficult to be corroded by acid, alkali, the material that the cable is used in addition is nontoxic, beneficial to environmental protection；Insulating performance of cable is fabulous, insulation Layer is non-aging, is effectively prevented the generation of leaky, and cable is provided with screen layer, can be very good protection cable and is subject to The intrusion of introduced contaminants and moisture, is effectively prevented damage of the external force to cable, 3）The technical scheme is set between core There is filler, the filler is the cordage of steel wire parcel；Anti-wear performance is high, the cordage wrapped up by steel wire, strengthens The whole intensity of cable, additionally, steel wire outer surface can also be coated with nylon layer, further makes cable wear-resistant, extends cable Service life, additionally, the middle setting of the high-strength cable has cylindrical wear-resisting support, the wear-resisting support is arranged on first In the middle of cable, with good support effect, secondly, all spaces inside cable are filled with filler, greatly strengthen The wearability of cable；4）The technical scheme cost is relatively low, is easy to large-scale popularization and application.
