Jklyj 1kV / 10kV overhead insulated cable anti-aging special aluminum core overhead wire for rural reconstruction
Overhead cable (full name: overhead insulation > cable) is an overhead conductor with insulating layer and protective sheath. It is a special cable manufactured by a production process similar to cross-linked cable. It is a new power transmission mode between overhead conductor and underground cable. Overhead cables are single core. According to their different structures, they can be divided into hard aluminum wire structure, hard drawn copper wire structure, aluminum alloy wire structure, steel core or aluminum alloy core support structure and self-supporting three core corrugated structure (the wire core can be hard aluminum or hard copper wire), etc. It has the main characteristics of high power supply reliability, good power supply safety, convenient erection and maintenance and reasonable economy. Its main technical parameters include weather resistance, insulation level, inner and outer semi-conductive shielding layers. Overhead cables are widely used in power transmission at home and abroad.
