Problems solved by technology

The current tension-resistant cables mainly use tensile steel wires to increase the tensile capacity, but the internal arrangement of the cables still adopts a parallel double-layer structure. The core wires of this cable structure are loose, and the internal core wires will be displaced during use. Insufficient tensile force, easy to twist, short service life

Abstract

The invention discloses a tensile anti-torsion cable comprising conductors, a filling core, an inner sheath and an outer sheath, and an anti-torsion layer; the three conductors are twisted to form a cable core; the filling core is arranged in the cable center; the cable core surrounds the filling core; the inner sheath extrudes around the cable core in an embedded manner; the outer sheath is filled outside the inner sheath; the anti-torsion layer is added between the inner and outer sheaths. The tensile anti-torsion cable can realize conductor grouped cabling, is filled with high strength tensile aramid fibers, and the sheath is filled with aramid fiber braided fabrics; the tensile anti-torsion cable is tensile and anti-torsion, and long in service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to a tensile and torsion-resistant cable. Background technique [0002] With the advancement of the industrialization process, many machines in China need to run and move repeatedly during the working process, and the cables in the machines will also be twisted repeatedly. Long-term high-load torsion will cause the cable to be twisted, the sheath will be worn out, and the cable core will be broken, which will lead to open circuit, short circuit, and sheath rupture. This sudden situation will cause serious harm to machinery, equipment and personnel, and will also affect the life of the machine. [0003] Therefore, the cables used by large machinery require very high tensile strength. Imported cables generally have a service life of 2,000 hours, and they also have insufficient tensile strength, and problems such as torsion and breakage will occur if they are used for a long time. The current ...
