The 4 main classifications of Distribution Cable:
1. Bare wire body products
The main features of this kind of product are: pure conductive metal, no insulation, and a sheath layer, such as steel-cored aluminum stranded wire, copper-aluminum busbar, electric locomotive wire, etc.; the processing technology is mainly pressure processing, such as smelting, calendering, drawing system, stranding/compression stranding, etc.; products are mainly used in suburban areas, rural areas, user main lines, switch cabinets, etc. The main features of this type of product are: extruding (winding) the insulating layer outside the conductor, such as overhead insulated cables, or twisting several cores (corresponding to the phase wire, neutral wire, and ground wire of the power system), such as overhead insulated cables with more than two cores, or add a sheath layer, such as plastic/rubber sheathed wires and cables. Main technology has drawing, stranded, insulation extruded (wrapped), stranding, armoring, and sheath to extrude, etc., and the different operation combinations of various products have certain differences. The products are mainly used in the transmission of strong electric power in the transmission, distribution, transmission, transformation, and power supply lines. The passing current is large (tens of amps to thousands of amps), and the voltage is high (220V to 35kV and above).
2. Wire and cable for electrical equipment
The main features of this kind of product are: various varieties and specifications, a wide range of applications, and the use of voltage is more than 1kV and below. For special occasions, new products are constantly derived, such as fire-resistant cables, flame-retardant cables, low-smoke and halogen-free/low-smoke Low-smoke low-halogen cables, termite-proof, mouse-proof cables, oil-resistant/cold-resistant/temperature-resistant/wear-resistant cables, medical/agricultural/mining cables, thin-walled wires, etc.
3. Communication cables and optical fibers
With the rapid development of the communication industry, from the 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. The structural size of this type of product is usually small and uniform and requires high manufacturing precision.
4. Winding wire
A winding wire is a conductive metal wire with an insulating layer, which is used to wind coils or windings of electrical products. When it works, it generates a magnetic field through the current, or cuts the magnetic force line to generate an induced current, and realizes the conversion of electric energy and magnetic energy, so it becomes an electromagnetic wire.
