According to product classification, it is divided into five categories.
1. Bare wires and bare conductor products
The main characteristics of this kind of products are: pure conductor metal, no insulation and sheath layer, such as steel-core aluminum stranded wire, copper-aluminum bus bar, electric locomotive wire, etc. The processing technology is mainly pressure processing, such as melting, calendering, drawing, twisting/compression twisting, etc. Products are mainly used in suburbs, rural areas, main lines of users, switch cabinets and so on.
2. Power cable
The main features of this kind of products are: extruding (winding) the insulation layer outside the conductor, such as overhead insulated cable, or twisting several cores (corresponding to the phase, neutral and ground wires of power system), such as overhead insulated cable with more than two cores, or adding a sheath layer, such as plastic/rubber sheathed wire and cable. The main technologies include drawing, twisting, insulation extrusion (wrapping), cabling, armoring, sheath extrusion, etc. There are some differences in different process combinations of various products.
The products are mainly used for the transmission of high-voltage electric energy in power generation, distribution, transmission, transformation and power supply lines, with large current (tens of amperes to thousands of amperes) and high voltage (220V to 500kV and above).
3. Wires and cables for electrical equipment
The main features of this kind of products are: a wide range of specifications, a wide range of applications, and more voltage of 1kV and below. Facing special occasions, new products are constantly derived, such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free cables, termite-proof cables, mouse-proof cables,oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables, medical/agricultural/mining cables, thin-walled wires and so on.
4. Communication cables and optical fibers
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. This kind of products usually have small and uniform structural dimensions and require high manufacturing accuracy.
5. Electromagnetic wire (winding wire)
Mainly used in various motors, instruments and meters, etc.
