Power cables are defined as cables characterized by a large conductor diameter, typically comprising three or four cores, featuring relatively thick inter-phase insulation, and protected on the exterior by metal armor. They are utilized within power supply systems to serve as the main trunk lines for three-phase industrial power or single-phase residential power distribution.
Power cables constitute a specific category of electric cables, designed expressly for transmitting electrical energy to power-consuming equipment-such as electric motors, machine tools, and industrial robots-and are primarily deployed as the main trunk lines for three-phase industrial power or single-phase residential power supplies.
The wires and cables employed within power systems primarily include overhead bare conductors, busbars, power cables (including plastic-insulated cables, oil-impregnated paper-insulated cables-which have largely been superseded by plastic power cables-rubber-sheathed cables, and overhead insulated cables), branch cables (which serve as substitutes for certain busbar applications), magnet wires, and electrical wiring specifically designed for power equipment.
Wires and cables utilized in information transmission systems primarily include local telephone cables, television cables, electronic cables, radio-frequency (RF) cables, fiber optic cables, data cables, magnet wires, and power-communication composite cables, among others.
In this specific sector, nearly every type of wire and cable product finds application-with the exception of overhead bare conductors; however, the products predominantly utilized are power cables, magnet wires, data cables, and instrumentation cables.
