Application classification of wires and cables

1.Power system，The main wire and cable products used in the power system include overhead bare wires, bus bars (buses), power cables (plastic cables, oil-paper power cables (basically replaced by plastic power cables), rubber sheathed cables, overhead insulated cables), branch cables (replacing some buses), electromagnetic wires, and electrical equipment wires and cables for power equipment；2.Information transmission system，There are mainly local telephone cables, television cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic cables, power communication cables, or other composite cables；3. Mechanical equipment, instrumentation systems，Almost all products except overhead bare wires are used in this section, but mainly power cables, electromagnetic cables, data cables, instrument cables, etc.

Wire and cable product classification

1. Bare wires and bare conductor products. The main characteristics of this category of products are: pure conductor metal, without insulation and sheath layers, such as steel core aluminum stranded wire, copper aluminum bus bars, electric locomotive wires, etc; The processing process is mainly pressure processing, such as smelting, calendering, drawing, stranding/compression stranding, etc; The products are mainly used in suburban areas, rural areas, user mainlines, switch cabinets, etc；2. Power cables. The main characteristics of this type of product are: extruding (winding) an insulating layer around the conductor, such as overhead insulated cables, or twisting several cores (corresponding to the phase, neutral, and ground wires of the power system), such as overhead insulated cables with more than two cores, or adding a sheath layer, such as plastic/rubber sheathed wires and cables. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cabling, armor, sheath extrusion, etc. The different process combinations of various products vary. The product is mainly used for the transmission of strong electric 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. Electric wires and cables for electrical equipment. The main characteristics of this type of products are: a wide variety of specifications, a wide range of applications, and a wide range of operating voltages of 1 kV and below. In the face of special situations, new products are constantly derived, such as fire-resistant cables, flame retardant cables, low smoke zero halogen/low smoke low halogen cables, anti-termite, mouse resistant cables, oil/cold/temperature/wear resistant cables, medical/agricultural/mining cables, thin-walled wires, etc；4. Communication cables and optical fibers have evolved 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. The structural dimensions of these products are usually small and uniform, with high manufacturing accuracy requirements；5. Electromagnetic wire (winding wire) is mainly used for various motors, instruments, etc.
