1.Bare wires and bare conductor products
The main characteristics of this type of product are: pure conductor metal, without insulation or sheath layer, such as steel core aluminum stranded wire, copper aluminum busbar, electric locomotive wire, etc;
The processing technology mainly involves pressure processing, such as melting, rolling, drawing, stranding/compression stranding, etc;
The product is mainly used in suburban areas, rural areas, user mainlines, switchgear, etc.
2.Power cable
The main characteristics of this type of product are: extruding (winding) an insulation layer outside the conductor, such as overhead insulated cables, or twisting several cores (corresponding to the phase, zero, and ground wires of the power system), such as overhead insulated cables with two or more cores, or adding a protective layer, such as plastic/rubber sheathed wires and cables.
The main process technologies include drawing, stranding, insulation extrusion (wrapping), cable forming, armor, sheath extrusion, etc.
The different process combinations of various products have certain differences.
The product is mainly used for the transmission of strong electrical energy in power generation, distribution, transmission, transformation, and power supply lines, with high current (tens to thousands of amperes) and high voltage (220V to 500kV and above).
3.Wire and cable for electrical equipment
The main characteristics of this type of product are: a wide variety of specifications, a wide range of applications, and a wide range of voltages below 1kV.
In the face of special occasions, new products are constantly derived, such as fire-resistant cables, flame-retardant cables, low smoke zero halogen/low smoke low halogen cables, termite resistant, mouse resistant 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 communication industry in the past twenty years, products have also experienced an astonishing pace of development.
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 type of product usually has small and uniform structural dimensions, and requires high manufacturing accuracy.
5.Electromagnetic wire (winding wire)
Mainly used for various motors, instruments, etc. Derivative/new products of wires and cables: The derivative/new products of wires and cables mainly adopt new materials, special materials, or change the product structure to use different materials such as flame retardant cables, low smoke zero halogen/low smoke low halogen cables, anti termite, anti mouse cables, oil/cold/temperature resistant cables, etc. due to different application scenarios, application requirements, convenience of equipment, and requirements for reducing equipment costs; Change the product structure, such as fire-resistant cables; Improve process requirements such as medical cables; Combination products such as OPGW; Convenient installation and reduced equipment costs, such as prefabricated branch cables, etc
