Wire and cable manufacturers commonly classify wires and cables into 5 categories. Let's take a detailed look. The common classification of wire and cable manufacturers for power cables is that the primary feature of this type of product is to extrude (wrap) an insulation layer around the conductor, such as overhead insulated cables, or twisted several cores (corresponding to the phase, neutral, and ground wires of the power system).

Such as overhead insulated cables with two or more cores, or additional protective sheaths such as plastic/rubber sheathed wires and cables. The primary process technologies include drawing, twisting, insulation extrusion (wrapping), cabling, armor, protective layer extrusion, etc. The different process combinations of various products have certain differences. The product is primarily used for the transmission of strong electrical energy in power generation, distribution, transmission, transformation, and supply lines, passing through high currents (tens of amps to thousands of amps) and high voltages (220V to 500kV and above).

The primary characteristic of bare wires and bare conductor products in this category is: pure conductor metal, without insulation or sheath layer, such as steel core aluminum stranded wire, copper aluminum busbar, electric locomotive wire, etc; The primary processing technology is pressure processing, such as melting, rolling, drawing, twisting/compression twisting, etc; The product is primarily used in suburban areas, rural areas, user main lines, switchgear, etc.
