1. Bare wire and bare conductor products
The main characteristics of this type of product are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper and aluminum bus bar, electric locomotive wire, etc.; the processing technology is mainly pressure processing, such as melting, rolling, drawing System, stranding / compacting stranding, etc .; products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.
2. Power cable
The main characteristics of this type of product are: squeezing (winding) an insulation layer outside the conductor, such as an overhead insulated cable, or a few-core stranded (corresponding to the phase line, neutral line and ground wire of the power system), such as a two-core or more overhead insulated cable , Or increase the jacket layer, such as plastic / rubber sleeve wire and cable. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable formation, armoring, sheath extrusion, etc. The different process combinations of various products are somewhat different.
The product is mainly used in the transmission of strong electric energy in the generation, distribution, transmission, transformation and power supply lines. The current passed is large (tens of amperes to thousands of amperes) and the voltage is high (220V to 500kV and above).
3. Wire and cable for electrical equipment
The main characteristics of this type of product are: a wide variety of specifications, a wide range of applications, and a voltage of 1kV and below, and new products are constantly derived in the face of special occasions, such as fire-resistant cables, flame-retardant cables, low-smoke, halogen-free / low Smoke-low halogen cables, termite-proof, mouse-proof cables, oil-resistant / cold-resistant / temperature-resistant / wear-resistant cables, medical / agricultural / mining cables, thin-walled wires, etc.
