[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a wear-resistant and tensile-resistant cable to solve the above technical problems, and its technical solution is as follows:

[0026] A wear-resistant and tensile-resistant cable, comprising:

[0027] The reinforcing core 4, as the skeleton of the cable, can replace the conductor core 1 to withstand the stress generated inside the cable when the cable is dragged, and effectively protect the insulating core from being broken;

[0028] The reinforcing core 4 is circumferentially fixedly connected with three evenly spaced partition plates 5; the partition plates 5 are used to separate the conductor cores 1 and ensure that they are kept in the correct position to prevent interference and wear between each other, and can provide a certain degree of compressive support. When the cable is squeezed, the three partition plates 5 give support force to the conductor core 1 to limit the conductor core 1 from being squeezed and deformed;

[0030] Each conductor core 1 is wrapped with a shielding layer 2 on the outside; the shielding layer 2 is provided to reduce external electromagnetic interference and protect the quality of the signal;

[0031] The space between the conductor core 1 and the partition plate 5 is filled with a refractory material 3; the outer side of the refractory material 3 is wrapped with a mica tape layer 6; the refractory material 3 is combined with the mica tape layer 6 to improve the fire resistance of the cable;

When the cable is dragged on the ground, the wear-resistant convex ridges 12 can be used as the main grounding position of the outer side of the cable, which can avoid the wear-resistant sheath layer 10 from directly contacting the ground, prevent the wear-resistant sheath layer 10 from being worn, enhance the wear resistance of the cable, and increase the anti-friction ability of the cable surface;

[0034] Among them, a plurality of tensile ropes 8 are embedded in the tensile layer 9; the tensile layer 9 cooperates with the tensile ropes 8 to improve the tensile performance of the cable, and can effectively protect the insulating core from being broken when the cable is dragged;

[0036] The conductor core 1 is formed by twisting copper wires and aramid fiber wires; the conductor core 1 adopts a composite conductor structure, which not only ensures the transmission channel of the current, but also twists the high-strength aramid fiber wires with the copper monofilaments at the same time to improve the overall tensile performance of the conductor.

[0037] In this embodiment, the reinforcing core 4 and the partition plate 5 are both made of polyethylene; the reinforcing core 4 and the partition plate 5 are integrally formed; the reinforcing core 4 uses high-strength and high-elongation polyethylene as the main material and has good mechanical strength.

[0039] In this embodiment, the materials of the tensile layer 9 and the fiber reinforcement layer 10 are both aramid fiber, which is a synthetic fiber with extremely high tensile strength and wear resistance.

[0040] In this embodiment, the wear-resistant sheath layer 11 and the wear-resistant convex ridges 12 are both made of cross-linked polyethylene, and the wear-resistant sheath layer 11 and the wear-resistant convex ridges 12 are extruded integrally by an extruder; cross-linked polyethylene has excellent wear resistance, can resist external friction and wear, and protect the internal structure of the cable from damage.

[0041] In this embodiment, the refractory material is fireproof glass wool or cotton rope or magnesium oxide.

[0042] The wear-resistant and tensile-resistant cable provided by the new embodiment has the following beneficial effects: The utility model designs a wear-resistant and tensile-resistant cable, which can effectively improve the safety of cable use and ensure the normal operation of equipment.
