The cables are habitually classified into weak electric cables of 450/750V and below, low voltage cables of 0.6/1kV, medium voltages of 3-35kV, high voltages of 35-110kv, and ultrahigh voltages of 110-750kV depending on the voltage level.
Low-voltage cables can be produced using ordinary polyvinyl chloride and cross-linked polyethylene.
Low-pressure cross-linking and common distinction, while medium-high voltage is not cross-linked cable, 6kv-35kv uses three-layer co-extrusion, high Production of density crosslinked polyethylene.
1KV low voltage cable and 6/10kV, 8.7/10kV medium voltage cable, the former is voltage level 1kV, commonly used products.
