Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

Given by figure 1, a high strength tensile cable, includes steel wire 1, its characterized in that, 1 outside of steel wire is equipped with the cable layer, the cable layer includes many cable conductor 14, and the outside on cable layer is equipped with shielding layer 4, the shielding layer 4 outside is equipped with protection endotheca 5, fire-retardant layer 6, anticorrosive coating 7, dampproof course 8, water-blocking tape 9 and protective coat 15 by inside to outside in proper order, protective coat 15 is inside to be equipped with many metal wire drawing 3, one side that many metal wire drawing 3 deviate from steel wire 1 all is fixed with connecting portion 10, the one end that metal wire drawing 3 was kept away from to a plurality of connecting portions 10 all stretches out protective coat 15.

This device is when using, places the place of needs with the cable, and the inside steel wire 1 of cable can make the whole fine pull resistance that has of cable, and steel wire 1 can make the cable carry out crooked installation more easily simultaneously, and the cable blanket outside is equipped with shielding layer 4, has improved the stability when the cable uses. The outside protective outer sleeve 15 of shielding layer 4 can make the inside material of protective inner sleeve 5 compacter, reduces the wearing and tearing that produce, and fire-retardant layer 6 can prevent the cable to be damaged by high temperature, and anticorrosive coating 7 and dampproof course 8 can avoid the cable to be rotten in moist environment, stability when improving the cable use. The water-blocking tape 9 can effectively prevent liquid from damaging the cable, the protective outer sleeve 15 can reduce the abrasion of the cable, and the cable is protected preliminarily. Be equipped with a plurality of metal wire drawing 3 in protective coating 15 inside, the tensile strength of improvement point cable that can be further, stretch out protective coating 15 with metal wire drawing 3 fixed connection's connecting portion 10 for after the heat transfer that the cable produced is to metal wire drawing 3, can be through connecting portion 10 outside conduction, and then improve the life of cable.

The ends of the connecting parts 10 extending out of the protective outer sleeve 15 are respectively fixed with a wear-resistant plate 13, and a gap is arranged between the wear-resistant plate 13 and the protective outer sleeve 15.

Through setting up wear plate 13 for the cable can be protected the cable when dragging, avoids the cable to produce wearing and tearing, thereby has improved the life of cable, and leaves the clearance between wear plate 13 and protective sheath 15, thereby can not exert an influence to the heat dissipation of cable self, further improvement cable's life.

The wear-resistant plate 13 and the connecting part 10 are both made of heat-conducting silica gel sheets.

The heat conduction silica gel sheet has good heat conductivity, so that heat generated by the cable can be conducted, and the heat is quickly conducted to the wear-resistant plate 13, so that the heat dissipation area is increased, the heat dissipation effect is improved, and the service life of the cable is prolonged.
