Abstract

The invention discloses a high-reliability electric power cable. The high-reliability electric power cable comprises multiple conductors, a wrapping layer which is arranged on the exteriors of the conductors in a wrapping manner, an insulating layer which is arranged on the exterior of the wrapping layer in an extrusion manner, a shielding layer which is arranged on the exterior of the insulating layer in a wrapping manner, a waterproof layer which is arranged on the exterior of the shielding layer in a coating manner, a fireproof layer which is arranged on the exterior of the waterproof layer in a packaging manner, and an outer sheath which is arranged on the exterior of the fireproof layer in an extrusion manner. The high-reliability electric power cable provided by the invention has the characteristics of high temperature resistance, fireproof and flame-retardant property, waterproof and oil-resistant property, aging resistance, and long service life; meanwhile, the high-reliability electric power cable also has high physical and mechanical performance, tearing strength and processing property; the high-reliability electric power cable can be applied to occasions of high-rise buildings, airports, wharfs, underground railroads and the like for ensuring continuous operation of firefighting power utilization equipment and important equipment, such as a fire pump, a fire lift, partial lamination, emergency evacuation indication, security and monitoring, a smoke preventing and exhausting system, a self-contained power supply and the like in a fire situation; and in addition, the high-reliability electric power cable is applicable to water treatment equipment, such as a submerged pump, a coal mine, an underwater operation, a water landscape lamp and the like.

Description

technical field [0001] The invention relates to a cable, in particular to a high-reliability power cable. Background technique [0002] Power cables are cables used to transmit and distribute electrical energy. It is 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 electric energy in the main lines of the power system, including 1-500KV and above various voltage levels and various insulated power cables. The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's la...
