Wire and cable are collectively referred to as wire products used to transmit electrical (magnetic) energy, information, and convert electromagnetic energy. Wire and cable can be divided into five main categories based on their intended use:
1. Bare wire: Products consisting solely of conductors without insulation, such as steel-core aluminum stranded wire, aluminum stranded wire, and copper stranded wire. These products are primarily used in suburban and rural areas, user main lines, and switchgear.
2. Winding wire (electromagnetic wire): Wire that, in a winding form, cuts magnetic lines in a magnetic field to induce current, or passes current through it to generate a magnetic field. These are primarily used in various motors, instruments, and meters. Examples include enameled wire.
3. Power cable: Cable products used to transmit and distribute high-power electrical energy within the main lines of power systems, such as cross-linked polyethylene insulated power cables. These products are primarily used for high-power energy transmission within power generation, distribution, transmission, transformation, and supply lines, carrying high currents (from tens of amperes to several thousand amperes) and high voltages (from 220V to 500kV and above).
4. Communication cables and optical cables: Cables and optical cables used to transmit telephone, telegraph, television, radio, fax, data, and other telecommunications information.
5. Electrical equipment wires and cables: Wires and cables used to transmit electrical energy directly from the power distribution point of the power system to the power connection lines of various electrical equipment and appliances. Examples include control cables and wiring cables.
