1. Information transmission system
Including local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic cables, power communication or other composite cables.
2, mechanical equipment, instrumentation system
In addition to the overhead bare wire, almost all products can be applied to this system, but mainly power cables, electromagnetic cables, data cables and instrument cables.
3. Power system
These cables include bare overhead cables, bus bars (bus bars), power cables (plastic cables, oil-impregnated paper cables (basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables, branch cables (partially replaced by bus bars), electromagnetic cables, and electrical equipment wires and cables for power equipment.


Wire and cable product type
1. Power cable
The main feature of this type of product is that the conductor is covered (wrapped) with insulation, such as overhead insulated cables, or multi-core stranded (for the phase line, neutral line and ground line of the power system), such as more than two core overhead insulated cables, or coupled with a sheath layer, such as plastic/rubber sheathed wire and cable. The main process technology includes drawing, stranding, insulation extrusion (wrapping), cable forming, armor and sheath extrusion, etc. The process combination of different products is slightly different. Mainly used in power generation, distribution, transmission, transformation and power supply lines in the strong power transmission, carrying large current (tens to thousands of amPs) and high voltage (220V to 500kV and above).
2, electrical equipment with wire and cable
This type of product is characterized by a wide range of specifications, a wide range of applications, the use of voltage is mainly 1kV and below, in the face of special occasions will be derived new products, such as fire-resistant cables, flame retardant cables, low-smoke halogen free/low-smoke low-halogen cables, termite-proof, anti-mouse cables, oil/cold/temperature/wear resistant cables, medical/agricultural/mining cables, thin-wall wires.
3, bare wire and bare conductor products
This kind of product is mainly characterized by pure metal conductors, without insulation and protective layer, such as steel core aluminum stranded wire, copper and aluminum bus, electric locomotive line, etc. The processing technology mainly includes melting, calendering, drawing and stranding/compacting stranding. Mainly used in urban suburbs, rural areas, user main line and switchgear and other fields.
4, electromagnetic wire (winding wire)
Mainly used for all kinds of motors, instruments and meters.
5. Communication cables and optical fibers
From simple telephone and telegraph cables to now thousands of dialogue cables, coaxial cables, optical cables, data cables, and even combined communication cables. The size of such products is usually small and uniform, and the manufacturing accuracy is required.
