Five Major Categories of Wire and Cable Products

1.Bare wires and bare conductor products

The main features of this product are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper-aluminum busbar, electric locomotive line, etc.; processing technology is mainly pressure processing, such as smelting, rolling, pulling System, stranding/tightening stranding, etc.; products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.

2.Power cable

The main features of this type of product are: extrusion (winding) insulation on the outer conductor, such as overhead insulated cable, or stranding (corresponding to the phase, neutral and ground of the power system), such as overhead insulated cables with two cores or more , or add a jacket layer, such as plastic / rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (winding), cable-forming, armoring, and sheath extrusion. The different process combinations of various products have certain differences.

The products are mainly used for transmission of strong electric energy in the transmission, distribution, transmission, transformation and power supply lines. The current passing through is large (tens of amps to several thousand amps) and the voltage is high (220V to 500kV and above).

3.Electrical equipment wire

The main characteristics of this kind of products are: a wide variety of specifications, a wide range of applications, the use of voltage in 1kv and below, in the face of special occasions continue to derive new products, such as fire-resistant cable, flame retardant cable, low smoke halogen-free / low-smoke low-halogen cable, oil / cold / temperature / wear-resistant cable, medical / agricultural / mining cable, thin-wall wire and so on.

4.Communication cable and fiber

With the rapid development of the communication industry in the past two decades, the products have also experienced phenomenal growth. From the simple telephone telegraph cable of the past to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even combined communication cable.

The structural dimensions of such products are generally small and uniform, and manufacturing precision is required.

5.Electromagnetic wire (winding wire)

Mainly used in various motors, instrumentation, etc.
