Abstract

The invention discloses a heat-resistant aluminum alloy high-voltage electric power cable comprising a cable core, an insulating layer, a shielding layer and a jacket layer, wherein the insulating layer covers outside the cable core, the shielding layer covers outside the insulating layer, and the jacket layer covers outside the shielding layer; and the cable core is made of a heat-resistant aluminum alloy lead, and the jacket layer is made of modified butadiene-nitrile rubber. The heat-resistant aluminum alloy high-voltage electric power cable disclosed by the invention is excellent in heat resistance and has excellent wear resistance.

Description

technical field [0001] The invention relates to the technical field of power voltage, in particular to a heat-resistant aluminum alloy high-voltage power cable. Background technique [0002] With the rapid development of the national economy, the amount and scope of use of power cables as the main artery of the national economy are increasing. 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. With the development of society and economy, the consumption of heat-resistant aluminum alloy high-voltage power cables is increasing rapidly, and the quality requirements for cables are also constantly improving. At present, the wear resistance and heat resistance of heat-resistant aluminum alloy high-voltage power cables need to be improved urgently. Content...
