Overhead insulated 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.
Application: parallel bundle overhead insulated cable is a new type of conductor material formed by improving the manufacturing process and structure of conductor based on the application of foreign stranded insulated conductor. The product has the advantages of weather resistance, anti light aging, convenient erection, low line loss, safety and reliability, and has broad prospects in rural low-voltage power grid
Application: the hollow wire of round wire concentric winch refers to the conductive wire without insulation and protective layer. Due to its low price and convenient installation and maintenance, it is widely used for long-distance transmission of electric energy in power lines. Its main products include aluminum strand, steel cored aluminum strand, aluminum clad steel cored aluminum strand, aluminum alloy strand, aluminum clad steel strand, etc
