Problems solved by technology

In actual use, it is found that the cable using steel wire rope on one side will still extend due to the influence of gravity on the other side for a long time. The longer the use time, the more severe the extension. In order to overcome this shortcoming , a reinforced structure with steel wire ropes on both sides is designed. Although this structure improves the problem of hanging on one side, it also increases the manufacturing cost, and this kind of reinforcement only strengthens the outer sheath of the cable, and it does not affect the strength of the cable core. Enhancement is not great

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 , 3 As shown, it is an embodiment of the tensile cable in the present invention, which is a cross section of 400mm 2 The tensile cable within, the tensile cable includes a conductive electric core 1, a tensile member 2, an outer sheath 3 and a wrapping tape 4, the conductive electric core 1 includes a wire 101 and an insulating layer 102 wrapped outside the wire 101, and the tensile Part 2 includes a steel wire rope 201 and a sheath layer 203 wrapped on the steel wire rope 201. The steel wire rope 201 is a tinned flexible steel wire rope, and the sheath layer 203 is made of nylon. The tensile parts 2 are arranged in parallel to form the inner core, the outer sheath 3 is wrapped on the inner core, and the cross section of the outer sheath 3 is circular; the wrapping tape 4 is spirally wound on the inner core, ...

Abstract

The invention discloses a tensile cable which comprises a conductive core, a tensile member and an outer sheath. The conductive core comprises a conductive wire and an insulation layer which coats the conductive wire. The tensile member comprises a steel wire rope and a sheath layer which coats the steel wire rope. An inner core is formed by the conductive core and the tensile member. The outer sheath coats the inner core. The cross section of the outer sheath is a circle. According to the tensile cable, a circular structure is used, the problem of cable tensile property is solved effectively, the manufacturing cost is saved, and convenience is brought to large-scale popularization and application.

Description

technical field [0001] The present invention relates to a cable, in particular to a tensile cable. Background technique [0002] In order to enhance the tensile resistance of cables, the more reinforced structure is to extrude aramid fiber, hemp rope or directly use inferior insulating materials into a circular line with the same outer diameter as the cable core when the cable is cabled. It is twisted into a whole circular structure when cabled, or a heterogeneous structure reinforced with steel wire ropes on one or both sides of the outer sheath. Above-mentioned this kind of structure has advantages and disadvantages respectively, all can't reach ideal state when using. The cable structure using hemp rope and fiber is far less strong than that of steel wire, and its lifespan is also worse than others. However, aramid fibers are not water-resistant. On the other hand, if the gap between the cable cores is large, in order to ensure the roundness of the cable, a large amount...
