Technical Field

The utility model relates to the technical field of wires and cables, in particular to a folding-resistant round foot wire for wires and cables.

Background

The wire and cable are used to transmit electrical (magnetic) energy, information and wire products for electromagnetic energy conversion. The broad sense of electric wire and cable is also simply referred to as cable, and the narrow sense of cable is referred to as insulated cable, which can be defined as: an aggregate consisting of; one or more insulated cores, and their respective cladding, overall protective layer, and outer protective layer.

Through retrieving, the utility model of chinese patent application number CN210182119U discloses a wire and cable that flame retardant efficiency is good, including the cable core, the surface of cable core is provided with insulating sheath, insulating sheath's surface is provided with the filling rope, the surface parcel of filling rope has the inner sheath, the inner sheath includes polyvinyl chloride layer, TPE insulating layer and conductor shielding layer, one side that the filling rope was kept away from to the inner sheath is provided with the polyvinyl chloride layer, the surface parcel of inner sheath has the water-blocking layer, the surface parcel of water-blocking layer has the oversheath. The device has reached flame retardant efficiency good advantage through setting up cable core, insulating sheath, filling rope, inner sheath, water blocking layer and outer sheath's mutually supporting, has solved the poor problem of current wire and cable flame retardant efficiency. Based on above retrieval, above-mentioned cable line is mainly through setting up cable core, insulating sheath, filling rope, inner sheath, water-blocking layer and outer sheath's mutually supporting, has reached the effectual advantage of fire-retardant, and wherein deformation strength is relatively poor between inner sheath and the outer sheath, and whole cable line folding-resistant effect is relatively poor, can not satisfy the user demand.
