6. Application classification of wire and cable

1. Power system

The main wire and cable products used in the power system are bare overhead wires, bus bars (busbars), power cables (plastic cables, oil-paper force cables (basically replaced by plastic power cables), rubber sheath cables, overhead insulated cables), branch cables (replacing some bus bars), electromagnetic cables, and electrical equipment wires and cables for power equipment.

2. Information transmission system

Mainly include local telephone cable, TV cable, electronic cable, radio frequency cable, optical fiber cable, data cable, electromagnetic cable, power communication or other composite cable.

3, mechanical equipment, instrumentation system

This part in addition to the overhead bare wire almost all other products are used, but mainly power cables, electromagnetic cables, data cables, instrumentation cables and so on.

Seven, wire and cable product classification

1, bare wire and bare conductor products

The main features of this product are: pure conductor metal, no insulation and jacket layer, such as steel core aluminum stranded wire, copper and aluminum bus, electric locomotive line; The processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding/compression stranding, etc.; Products are mainly used in the suburbs, rural areas, user main line, switchgear and so on.

2. Power cable

The main features of this product are: extruded (wound) insulation layer outside the conductor, such as overhead insulated cable, or a few cores stranded (corresponding to the phase line, neutral line and ground line of the power system), such as more than two core overhead insulated cable, or add a sheath layer, such as plastic/rubber sheath wire and cable.

The main process technologies are drawing, stranding, insulation extrusion (wrapping), cable forming, armor, sheath extrusion, etc. There are certain differences in different process combinations of various products.

Products are mainly used in power transmission, distribution, transmission, transformer, power supply lines in the strong electric energy transmission, through the current (tens of amps to thousands of amps), high voltage (220V to 500kV and above).

3, electrical equipment with wire and cable

The main characteristics of this kind of products are: a wide variety of specifications, a wide range of applications, the use of voltage in 1kV and below more, in the face of special occasions constantly derived new products, such as refractory cables, flame retardant cables, low smoke halogen free/low smoke halogen cables, termite-proof, anti-mouse cables, oil/cold/temperature/wear resistant cables, medical/agricultural/mining cables, thin wall wires.

4. Communication cables and optical fibers

From the past simple telephone and telegraph cables have developed to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even combined communication cables. The structure size of this kind of product is usually small and uniform, and the manufacturing accuracy is high.

5, electromagnetic wire (winding wire)

Mainly used for all kinds of motors, instruments and meters.

Nine, the meaning of wire and cable specification notation

Specifications are expressed by number of cores, nominal cross section and voltage class

1, single-core branch cable specification representation: the number of cables in the same loop * (1* nominal section),0.6/1KV,

For example: 4*(1*185)+1*95 0.6/1KV

2, multi-core stranded branch cable specification representation: number of cables in the same loop * nominal section,0.6/1KV,

For example: 4**185+1*95 0.6/1KV
