The main classification of wires and cables

Bare wire body products The main characteristics of this type of product are: pure conductor metal, no insulation and sheath, such as steel core aluminum stranded wire, copper and aluminum bus bar, electric locomotive wire, etc .; the processing technology is mainly pressure processing, such as melting , Rolling, drawing, twisting / compact twisting, etc .; products are mainly used in suburbs, rural areas, customer main lines, switch cabinets, etc. Power cables Power cables Power cables Wires Cables Wires and cables The main features of this category of products are: Extruding (wrapping) insulation on the outside of the conductor, such as overhead insulated cables, or twisted cores (corresponding to the phase, neutral and ground of the power system Wire), such as overhead insulated cables with more than two cores, or additional sheaths, such as plastic / rubber sheathed wires and cables. The main process technologies include drawing, twisting, insulation extrusion (wrapping), cable formation, armoring and sheath extrusion, etc.

There are certain differences in the different process combinations of various products. The products are mainly used for the transmission of strong electric energy in power generation, distribution, transmission, transformation, and power supply lines, with large currents (tens of amps to thousands of amps) and high voltages (220V to 35kV and above). Electrical equipment, wires and cables, flat cables and flat cables (3 photos) The main characteristics of this type of product are: a large variety of specifications, a wide range of applications, the use of voltage is 1kV and below are more, and faced with special occasions, new products, such as refractory wires Cables, flame-retardant cables, low-smoke halogen-free / 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. Communication cables and optical fibers With the rapid development of the communication industry, from the past simple telephone and telegraph cables to thousands of pairs of telephone cables, coaxial cables, optical cables, data cables, and even combined communication cables. The structure size of such products is usually small and uniform, and the manufacturing accuracy is high. Winding wire A winding wire is a conductive metal wire with an insulation layer that is used to wind a coil or winding of an electrical product. When it works, it generates a magnetic field by electric current, or it generates an induced current by cutting magnetic lines of force to realize the conversion of electrical energy and magnetic energy, so it becomes an electromagnetic line.
