Abstract

The invention discloses a high performance aluminium alloy high voltage power cable which includes a cable core, an insulating layer, a shielding layer and a sheath layer. The insulating layer covers the outside of the cable core. The shielding layer covers the outside of the insulating layer. The sheath layer covers the outside of the shielding layer. The cable core is made of heatproof aluminium alloy leads, and the sheath is made of modified nitrile butadiene rubber. The high performance aluminium alloy high voltage power cable has excellent wear resistance and hear resistance.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a high-performance 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 high-performance 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 high-performance aluminum alloy high-voltage power cables need to be improved urgently. Co...
