Abstract

The invention discloses a power cable, and particularly relates to an aging-resistant power cable. The aging-resistant power cable comprises a conductor, the conductor is coated with an insulation layer, the insulation layer is coated with an inner sheath layer, the inner sheath layer is coated with an armor layer, and a protection layer is arranged on the outermost layer. The insulation layer is made of metallocene polyethylene plastic, and the metallocene polyethylene plastic is prepared from metallocene polyethylene, methyl vinyl silicone rubber, 1,1,3,3-tetramethyl peroxy-2-ethylhexoic acid butyl ester, potassium dichromate ammonium, modified silkworm pupa protein fibers, nanosilicon dioxide, glass beads, kieselguhr, calcium carbonate, Ca-Zn composite stabilizer, isopropyl-3(positive ethylamino-ethylamino) titanate, cycloparaffin oil, chlorcosane, zinc stearate, 3(1-hexadecanol) ester, tri-caprate and acetylacetone titanium. The aging-resistant power cable is resistant to ageing and extremely good in heat stability.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an aging-resistant 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. In power lines, the proportion of power cables is gradually increasing. Due to the concealed laying of power cables, the causes of power outages and short-circuit accidents are not easy to find. How to prepare a cable with good aging resistance and thermal stability has become a technical problem that needs to be solved at present. Contents of the invention [0003] The invention provi...
