Wire and cable products are mainly divided into five categories
1. Bare wire and bare conductor products
The main characteristics of this category of products are: pure conductor metal, no insulation and sheath layer, such as steel core aluminum stranded wire, copper aluminum busbar, electric locomotive wire, etc.; The processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding/tight pressing stranding, etc.; Products are mainly used in suburban areas, rural areas, user main line, switch cabinet, etc.
2. Power cable
The main characteristics of this type of products are: extruding (winding) the insulation layer outside the conductor, such as overhead insulated cable, or several cores stranded (corresponding to the phase line, zero wire and ground wire of the power system), such as overhead insulated cable with more than two cores, or adding a sheath layer, such as plastic/rubber wire and cable. The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable, armoring, sheath extrusion, etc., and the different process combinations of various products are different.
The products are mainly used in the transmission, distribution, transmission, transformation and power supply lines of strong electric power, through the current (tens of amps to thousands of amperes), high voltage (220V to 500kV and above).
3. Electrical equipment for wires and cables
The main characteristics of this type of products are: a wide variety of specifications, a wide range of applications, the use voltage of 1kV and below, in the face of special occasions continue to derive new products, such as fire-resistant cables, flame-retardant cables, LSZH / LSZH cables, anti-termites, anti-mouse cables, oil-resistant / cold-resistant / temperature-resistant / wear-resistant cables, medical/agricultural/mining cables, thin-walled wires, etc.
4. Communication cable and optical fiber
With the rapid development of the communication industry in the past two decades, the products have also developed at an amazing speed. From the simple telephone and telegraph cables of the past to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The structural size of such products is usually small and uniform, and the manufacturing accuracy is required.
5. Electromagnetic wire (winding wire)
Mainly used in various motors, instrumentation, etc. Derivatives of wire and cable/new products: Derivatives of wires and cables/new products are mainly due to the application and application requirements, the convenience of equipment and the requirements of reducing equipment costs, etc., and the use of new materials, special materials, or change the product structure Using different materials such as flame retardant cables, LSZH/LSZH cables, termite-proof, anti-mouse cables, oil-resistant/cold/temperature-resistant cables, etc.; Change the product structure, such as: fire-resistant cable, etc.; Improve process requirements such as: medical cables; Combination products such as: OPGW, etc.; Easy installation and reduced equipment costs, such as prefabricated breakout cables, etc.
