[0022] 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 ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1A wear-resistant wire and cable comprises a wire core 1, a support block 2 and a shielding layer 3 are arranged on the surface of the wire core 1, and a fireproof layer 4 is arranged on the outer surface of the shielding layer 3, a tensile resistance layer 5 is arranged on the surface of the fireproof layer 4, and a waterproof layer 6 is arranged on the surface of the tensile resistance layer 5, a high temperature resistant layer 7 is arranged on the surface of the waterproof layer 6, and a sheath 8 is arranged on the surface of the high temperature resistant layer 7, and a first wear-resistant layer 9 and a second wear-resistant layer 10 are arranged on the outer surface of the sheath 8 in sequence; the support block 2 is located inside the shielding layer 3, and the support block 2 divides the inside of the shielding layer 3 into four areas, the first wear-resistant layer 9 and the second wear-resistant layer 10 can play a good protective role on the outer surface of the cable to avoid cable friction damage, and the tensile resistance layer 5 can prevent the cable from being pulled and broken during use.

[0024] Furthermore, the support block 2 is made of heat-conducting rubber, and the transverse base surface of the support block 2 is in a "+" shape. The "+"-shaped support block 2 can provide good protection for the wire core 1 to avoid damage caused by squeezing.

[0025] Furthermore, the material of the fireproof layer 4 is halogen-free flame-retardant polyethylene. Adding halogen-free flame retardant to polyethylene can make it have good flame retardant properties. Halogen-free flame retardant is a new type of flame retardant material. Compared with traditional halogenated flame retardants, it has the advantages of environmental protection, anti-oxidation, and high temperature resistance. It has gradually become the preferred flame retardant for polyethylene materials; the working principle of halogen-free flame retardant is to inhibit the combustion of materials through chemical reactions or physical adsorption to prevent the spread of fire. According to the fire protection level of tinned copper stranded wire, 1%-5% of halogen-free flame retardant is generally added.

[0026] Furthermore, the anti-tear layer 5 is a mesh-shaped metal wire, which has excellent anti-tear property and durability, and can prevent the cable from breaking when being pulled.

[0027] Furthermore, the waterproof layer 6 is made of rubber, which has excellent electrical resistance and chemical resistance, as well as the advantages of high softness, good sealing, and strong anti-aging performance.

[0028] Furthermore, the first wear-resistant layer 9 is a corundum layer, and the second wear-resistant layer 10 is a polyurethane coating. The corundum can withstand high-intensity friction, impact and wear, and the polyurethane coating has excellent wear resistance, corrosion resistance and hardness. The corundum and polyurethane coating can improve the wear resistance of the outer surface of the sheath 8.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
