1. Bare wires and bare conductor products
The main features of this type of product are: pure conductor metal, no insulation and sheath, such as steel core aluminum stranded wire, copper aluminum bus, electric locomotive wire, etc .; the processing technology is mainly pressure processing, such as smelting, rolling, drawing Production, twisting / compact twisting, etc .; the products are mainly used in suburbs, rural areas, customer main lines, switch cabinets, etc.
The main features of this type of product are: extruding (wrapping) insulation on the outside of the conductor, such as overhead insulated cables, or twisted cores (corresponding to the phase, neutral and ground of the power system), such as overhead insulated cables with more than two cores , Or add another sheath layer, such as plastic / rubber sheathed wire and cable. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable formation, armoring, and sheath extrusion, etc. There are certain differences in the different process combinations of various products.
The products are mainly used for the transmission of strong electric energy in power generation, distribution, transmission, transformation, and power supply lines, with large currents (tens of amps to thousands of amps) and high voltages (220V to 500kV and above).
3.Wires and cables for electrical equipment
The main characteristics of this type of product are: a large variety of specifications, a wide range of applications, the use of voltage is more than 1kV, and faced with special occasions, new products continue to be derived, such as fire-resistant cables, flame-retardant cables, low smoke halogen-free 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.
4. Communication cables and optical fibers
With the rapid development of the communications industry over the past two decades, the products have also developed at an alarming rate. From simple telephone and telegraph cables in the past to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The structure size of such products is usually small and uniform, and the manufacturing accuracy is high.
5.Electromagnetic wire (winding wire)
Mainly used in various motors, instruments and so on. Derivatives / new products of wires and cables: Derivatives / new products of wires and cables are mainly used in new materials, special materials, or product structure changes due to different applications, different application requirements, and convenience of equipment and reduced equipment costs. Different materials such as flame-retardant cables, low-smoke halogen-free / low-smoke and low-halogen cables, termite-proof, mouse-proof cables, oil-resistant / cold-resistant / temperature-resistant cables, etc .; change product structure, such as fire-resistant cables; Such as: medical cables, etc .; combined products, such as OPGW, etc .; easy to install and reduce equipment costs, such as prefabricated branch cables.
