(1) Bare wire and bare conductor products
Pure conductor metal, without insulation and sheath layers, such as steel core aluminum stranded wire, copper aluminum busbar, electric locomotive wire, etc.
The processing technology is mainly pressure processing, such as melting, rolling, drawing, twisting/tensioning, etc.
The products are mainly used in suburbs, rural areas, main user lines, switch cabinets, etc.
(2) Power cord
The insulation layer is squeezed outside the conductor, such as overhead insulated cables, or twisted (corresponding to the phase line, neutral line, and ground wire of the power system), such as overhead insulated cables with more than two cores or sheathed.
Such as plastic/rubber sheathed wires and cables.
The main process technologies include drawing, stranding, insulation extrusion (winding), cabling, armouring, sheath extrusion, etc.
Different process combinations for various products have specific differences.
The products are mainly used for strong electric energy transmission in power transmission, distribution, transmission and transformation, and power supply lines.
The passing current is large (tens of amps to thousands of amps) and the voltage is high (220V to 500kV and above).
(3) Wires and cables for electrical equipment
It has various specifications and a wide range of applications, and the operating voltage is above and below 1kV. New products are constantly derived for special occasions, such as fire-resistant cables, flame-retardant cables, etc.
(4) Communication cables and optical fibers (brief introduction)
The structural dimensions of such products are generally small and uniform, and the manufacturing precision requirements are high.
(5) Electromagnetic wire (winding wire)
Mainly used in various motors, instruments, etc.
Derivatives/new products of wires and cables are mainly based on the requirements of application situations, application requirements, equipment convenience, and reducing equipment costs. They use new materials and special materials, change product structures, or improve process requirements, or they may be different.
Products of variables are combined to produce.
