Common classification methods of wires and cables can be used as a preliminary understanding

There are many kinds of wires and cables in daily life. The five common categories are:

1. Bare copper wire

Bare cable and bare conductor products refer to conductive cables without insulation layer and sheath, which mainly include three product series: bare single-wire railway, bare stranded wire and profiled aluminum profile. Copper-aluminum single-wire railway: including soft Copper single-track railway, hard copper single-track railway, soft aluminum single-track railway, carbon tool steel single-track railway.

The key is the bead wire of various cables and wires, and a small amount is used in the production of communication cables and electric motor household appliances. Bare stranded wire: including hard copper stranded wire (TJ), carbon tool steel stranded (LJ) , Aluminum alloy profile stranding (LHAJ), steel core aluminum stranded wire (LGJ) is mainly used for the connection of electrical equipment and weapons and electronic and electrical or components, and the specifications and models of various stranding range from 1.0-300mm2 different.

2. Power cables

Cable products used to transmit and distribute high-power electromagnetic energy in the main line of the power supply system, including wires and cables with various rated voltages and various insulation layers of 1-330KV and above. Wire and cable According to the rated voltage, it is divided into cables, high-voltage cables, high-voltage cables, etc. According to the state of the insulation layer, it is divided into plastic insulated wires, vulcanized rubber insulated wires, mineral insulated wires, etc.

3. Empty insulated wire

We are also very common in overhead wires, and its characteristic is that there is no grommet. Its electrical conductors are not only aluminum, but also copper electrical conductors (JKYJ, JKV), aluminum alloy profiles (JKLHYJ). Wire (JKLGY). It is not only single-core, generally all single-core, but it can also generate a bundle of 2 electrical conductors. The rated voltage of overhead wires is 35KV and below, not 1KV and 10KV. .

4. Inverter cable

The structure of this type of cable is similar to that of wire and cable. The characteristics are that there is only copper core, no aluminum core cable, the cross section of the electrical conductor is small, and there are many cable types. It is suitable for communication with AC rated current of 450\/750V and below, power plants, power plants, etc. Power station, mining, petrochemical company, etc. stand-alone operation or generator set equipment operation. In order to improve the working ability of the operation control cable to prevent accidental influence, the key is to set the shielding layer countermeasure.

5. Special cable

Special cables are cables with unique functions, including insulated wires (ZR), low-smoke halogen-free cables (WDZ), flame-retardant cables (NH), explosion-proof cables (FB), anti-fly cables and anti-white ants Cables (FS), water-retaining cables (ZS), etc. Continue to develop new products for unique places, such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free\/low-smoke halogen-free cables, low-halogen cables, Anti-white ant\/anti-mouse cable, acid and alkali resistant\/low temperature\/high temperature\/abrasion resistant cable, radiation cross-linked cable, etc.
