Tension-resistant and wear-resistant wire for electric power

Abstract

The invention relates to a tension-resistant and wear-resistant wire for electric power. The wire comprises a conductor wire core, a polyethylene insulating layer, a fluoroplastic insulating layer, a flame-retardant dacron woven reinforcing layer and a wear-resistant outer sheath layer in sequence from inside to outside, wherein the conductor wire core is formed by twisting a plurality of tin-plated round copper wires. The wear-resistant outer sheath layer is prepared from, by weight, 40-60 parts of butadiene-styrene rubber, 20-40 parts of chloroprene rubber, 23-26 parts of fluoroether rubber, 0.1-15 parts of graphene, 13-15 parts of phenolic resin, 1-10 parts of a silane coupling agent, 12-15 parts of semi-reinforcing furnace black, 10-12 parts of calcined clay, 1-2 parts of magnesium chloride, 1-5 parts of magnesium powder, 5-7 parts of nano-molybdenum disulfide (MoS2), 1-10 parts of an anti-aging agent, 0-20 parts of a plasticizer and 1-5 parts of an accelerant. The wire has excellent corrosion resistance, high temperature resistance, wear resistance, tear resistance and tensile resistance.

Description

technical field [0001] The invention relates to a tensile and wear-resistant electrical wire, which belongs to the technical field of electrical equipment. Background technique [0002] Although the wire and cable industry is only a supporting industry, it accounts for 1 / 4 of the output value of China's electrical industry. It has a wide variety of products and a wide range of applications, involving industries such as electric power, construction, communications, and manufacturing, and is closely related to various sectors of the national economy.

AI Technical Summary

Problems solved by technology

[0003] At present, the general structure of the power cord is composed of a wire core and an outer protective sheath covering the outer surface of the wire core. The outer sheath is made of polyvinyl chloride, which has the disadvantages of poor high temperature resistance, no wear resistance and no stretch resistance. , the power wires are often dragged and moved in actual use, which has extremely high requirements on the tear resistance and wear resistance of the wires, so the existing power wires can no longer meet the above requirements
