Heat-resistant and wear-resistant cable

Abstract

The invention relates to a heat-resistant and wear-resistant cable. The heat-resistant and wear-resistant cable comprises a wire core and a regular triangular prism tube body arranged on the outer side of the wire core, and is characterized in that the inner side of the regular triangular prism tube body is uniformly divided into four small regular triangular prism tube bodies, and the wire corecomprises four groups of twisted pairs; each group of twisted pair comprises two wires, an insulating layer wraps the outside of each wire, after being wrapped with the insulating layers, the two wires are twisted, and are lapped by a lapping layer which wraps the outside of the wires to form a cable, an inner shielding layer further coats the outside of the lapping layer, and an inner sheath further coats the outside of the inner shielding layer; the twisted pairs are separately arranged in the small regular triangular prism tube bodies, an outer shielding layer is further arranged on the outer side of the regular triangular prism tube body, the cable further comprises a rubber round tube which is arranged on the outer side of the outer shielding layer, a space between the outer shieldinglayer and the rubber round tube is filled with glass wool, a flame-retardant layer wraps the outer side of the rubber round tube, and an outer sheath wraps the outer side of the flame-retardant layer. The provided cable is heat-resistant and wear-resistant, and is unlikely to damage.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a heat-resistant and wear-resistant cable. Background technique [0002] In the existing Category 5e twisted pair cable, only the inner conductor is twisted to strengthen the overall tensile strength of the cable, and a shielding layer is added on the outside to increase the shielding effect; the cable with this structure is the inner conductor first. After twisting, there will be signal interference between each other, especially for the twisted pair cable with multi-conductor structure, the shielding effect is not good, and another convenience is that the cable with multi-conductor structure will squeeze each other between conductor groups, reducing stretching strength situation. Moreover, the cables will often be damaged during installation and use, and will be damaged after a long time. SUMMARY OF THE INVENTION [0003] The present invention provides a heat-resistant and w...

Problems solved by technology

[0002] In the existing Category 5e twisted-pair cable, only the internal conductors are twisted to enhance the overall tensile strength of the cable, and a shielding layer is added outside to increase the shielding effect; the cable with this structure, first of all, the internal conductor There will be signal interference between twisted pairs, especially for twisted pair cables with multi-conductor structure, the shielding effect is not good, another convenience is that the cables with multi-conductor structure will squeeze each other between the conductor groups, reducing the stretch intensity of the situation

Moreover, the cables are often subject to friction during installation and use, and will be damaged after a long time.
