Tensile cable

Abstract

The invention discloses a tensile cable, which belongs to the technical field of electric wires and cables. The tensile cable comprises a cable core formed by a group of conductors and an outer sheath extrusion-clad on the cable core, wherein each conductor is composed of a plurality of conductive single wires twisted with each other and an insulating protection layer extrusion-clad outside the conductive single wire. The tensile cable is characterized in that: the conductor also comprises enhancing fiber yarns which are mixed in the conductive single wires and twisted with the conductive single wires. In the technical scheme, the enhancing fiber yarns are mixed in the conductive single wires and twisted with the conductive single wires so as to ideally improve the tensile strength; moreover, as the conductive single wire needs to be twisted, additional process is not required for the doping twisting of the enhancing fiber yarns and therefore the process links are reduced compared with the existing technology.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a tensile cable. Background technique [0002] In the Chinese patent literature, there are many technical solutions around enhancing the tensile strength of cables, such as: self-adhesive tensile cables recommended by CN201408573Y, tensile cables provided by CN2906848Y, high-strength tensile cables disclosed by CN201219038Y, and so on. Cables with excellent tensile strength, such as an outdoor data type 5 flexible cable with an aramid reinforcement layer announced by the publication number CN101834031A and a light-duty environmentally friendly flame-retardant aramid silk fabric cable disclosed by the authorized announcement number CN201430011Y, these two patented technologies The schemes reflect the tensile strength of the cable by adding an aramid braid layer separately. More specifically, the tensile strength of the cable is guaranteed in a central...

Cables with excellent tensile strength, such as an outdoor data type 5 flexible cable with an aramid reinforcement layer announced by the publication number CN101834031A and a light-duty environmentally friendly flame-retardant aramid silk fabric cable disclosed by the authorized announcement number CN201430011Y, these two patented technologies The schemes reflect the tensile strength of the cable by adding an aramid braid layer separately. More specifically, the tensile strength of the cable is guaranteed in a centralized manner, but this method is prone to damage, because once If the aramid braid is damaged or partially damaged, the entire cable will lose its tensile effect

[0003] Perhaps for the above reasons, the structure of the common tensile cable in the prior art consists of figure 2 As shown, it includes a cable core 1 composed of several conductors 11, an outer sheath 2 extruded outside the cable core 1, and a group of steel wires 21 located in the outer sheath 2 at intervals. The tensile strength of this structure The cable has a good tensile effect, but there are also deficiencies, that is: the combination effect of the steel wire and the outer sheath is poor, and even the steel wire swims.
