Five Main Types of Cable

1.What are the types of cable?
The wire products used to transmit electric (magnetic) energy, information and realize the conversion of electromagnetic energy are collectively referred to as wires and cables. According to different purposes, wires and cables can be divided into five categories:

(1). Bare conductors: products with only conductors without insulation, such as steel core aluminum stranded wire(ACSR cable), aluminum stranded wire, and copper stranded wire. Products are mainly used in suburbs, rural areas, user main lines, switch cabinets, etc.

(2). Winding wire (magnet wire): In the form of a winding, the magnetic line of force is cut in a magnetic field to induce current, or a wire that generates a magnetic field with current. It is mainly used in various motors, instruments and meters. Such as enameled wire.

(3). Power cables: Cable products used to transmit and distribute high-power electrical energy in the backbone of the power system, such as cross-linked polyethylene (xlpe) insulated power cables. The products are mainly used in the transmission of strong electric energy in power generation, distribution, transmission, transformation, and power supply lines, with large current (tens of amperes to several thousand amperes) and high voltage (220V to 500kV and above).

(4). Communication cables and optical cables: cables and optical cables that transmit telephone, telegraph, television, radio, fax, data and other telecommunication information.

(5). Wires and cables for electrical equipment: Wires and cables used to directly transmit electrical energy from the power distribution point of the power system to the power connection lines of various electrical equipment and appliances. Such as control cables, wiring wires, etc.

2. What are the application of Cable?
Power system: The wire and cable products used in the power system mainly include overhead bare wires, busbars (bus bars), power cables (plastic cables, oil-paper cables (basically replaced by plastic power cables), rubber-sheathed cables, overhead insulated cables), Branch cables, electromagnetic wires, electrical equipment wires and cables for power equipment, etc.
Information transmission system: The wires and cables used in the information transmission system mainly include local telephone cables, television cables, electronic cables, radio frequency cables, optical cables, data cables, electromagnetic wires, power communications or other composite cables.
Mechanical equipment, instrumentation system: Except for overhead bare wires, almost all other products have applications, but mainly power cables, electromagnetic wires, data cables, instrument cables, etc.

3. What is the basic structure of wire and cable?

Conductor: An object that conducts current. The specifications of wires and cables are expressed by the cross-section of the conductor.
Insulation:
The insulating material is wrapped on the outside of the conductor in different thicknesses according to the requirements of its withstand voltage.
Protective layer: the part that protects the cable.
