Crosslinked polyethylene insulated flame-retardant waterproof ultraviolet-proof power cable

Abstract

The invention discloses a crosslinked polyethylene insulated flame-retardant waterproof ultraviolet-proof power cable in the technical field of cables. The cable comprises a conductor, an insulating layer, a winding layer, a shielding layer and an outer sheath, the insulating layer is extruded on the outer wall of the conductor; the winding layer wraps the outer wall of the insulating layer; the shielding layer wraps the outer wall of the winding layer; the insulating layer is formed by mixing isoprene rubber and silicone rubber. Through the isoprene rubber and the silicon rubber, the electricinsulation property of the cable insulation layer is improved; meanwhile, the strength, the high-low temperature resistance and the corrosion resistance of the cable insulating layer are improved; and the isoprene rubber, the butadiene styrene rubber, the butadiene rubber, the zinc oxide and the aluminum hydroxide are added into the cross-linked polyethylene, and the cross-linked polyethylene, the isoprene rubber, the butadiene styrene rubber, the butadiene rubber, the zinc oxide and the aluminum hydroxide are mixed together to prepare the outer sheath of the cable, so that the flame-retardant, waterproof and ultraviolet-proof capabilities of the cable are improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cross-linked polyethylene insulated, flame-retardant, waterproof, and ultraviolet-proof power cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal electrification and external insulation. [0003] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a cross-linked polyethylene insulated flame-retardant, waterproof, and UV-resistant power cable to solve the problem that the outer sheath of the existing power cable proposed in the above-mentioned background technology is only satisfied with the performance of wear resistance and aging resistance. However, it does not have the functions of waterproof and UV protection, and in order to use the power cable safely, the outer sheath of the cable must meet the flame retardancy, and the insulation layer of the existing power cable can only meet the insulation effect of the cable. The strength, high and low temperature resistance and corrosion resistance of the insulating layer are not good
