Cables are divided into signal cables and power cables. The former is used to transmit signals, such as cable TV optical cables and telephone cables, etc., and the latter is used to transmit electrical energy.
Communication wires and cables: including local telephone cables for communication networks in the city or local areas, long-distance communication cables (long-distance symmetrical communication cables, coaxial communication cables) for long-distance inter-city communication, local cables and various Communication wires.
Power cables: According to insulation type and structure, they can be divided into oil-impregnated paper insulated power cables, plastic insulated power cables and rubber insulated power cables.
The main uses of wire and cable are coils or windings for power transmission, electrical communication, and winding electrical equipment.
Wires and cables for electrical equipment: According to the characteristics of the product, it can be divided into general wires and cables, wires and cables for electrical equipment and instruments, wires and cables for vehicles, wires and cables for geological exploration and mining industries, signal control cables, and DC high-voltage cables.
The usefulness of the cable:
1.The wire and cable products used in the power system mainly include overhead bare wires, bus bars (busbars), power cables (plastic cables, oil-paper cables (basically replaced by plastic power cables), rubber-sheathed cables, overhead insulated cables), Branch cables (replacing some busbars), electromagnetic wires, and electrical equipment wires and cables for power equipment, etc.
2.Information transmission The wires and cables used in the information transmission system mainly include local telephone cables, TV cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communication or other composite cables, etc.
3.Instrument system This part is used in almost all products except overhead bare wires, but mainly power cables, electromagnetic wires, data cables, instrumentation cables, etc.
