Abstract

The invention relates to a 10-kV overhead insulated cable comprising a conductor. A shielding layer is arranged outside the conductor; an insulating layer is arranged outside the shielding layer; and a protective layer is arranged outside the insulating layer. The conductor consists of a high-strength carbon fiber composite core and heat-resistant aluminum alloy single wires arranged outside the high-strength carbon fiber composite core; and the high-strength carbon fiber composite core and the heat-resistant aluminum alloy single wires from a concentric twisting structure. The 10-kV overhead insulated cable has characteristics of light weight, high tensile strength, good electrical performance, high thermal stability, good creep property, and good weather-resistance performance.

Description

technical field [0001] The invention relates to a cable, in particular to an insulated cable. Background technique [0002] Traditional 10kV overhead insulated cables usually use aluminum stranded wires as conductors, ordinary semi-conductive materials, weather-resistant polyethylene as shielding, and a simple structure of insulating materials, because aluminum has strong metal activity and poor creep properties. Therefore, its service life and safety are all unsatisfactory. When ordinary overhead insulated cables are laid in mountainous areas or places with a drop in terrain and a large span, the cable often hangs seriously due to its own weight and cannot operate normally. [0003] At present, cable companies at home and abroad are actively looking for new materials to replace traditional overhead insulated cables. The first consideration for overhead cables is light weight, good insulation, and good aging and weather resistance. Contents of the invention [0004] Purp...
