1, data differences
Wires are conductive metal wires for carrying current. Having solid, twisted, or foil weaving and other forms. Insulation is divided into two categories: bare wire and insulated wire. An insulated wire consisting of one or more conductive wires insulated from one another and placed in a sealed sheath. It can add maintenance layers. The difference between wires and cables is that wires are usually smaller in scale and simple in layout, but sometimes cables are classified into broad wires.
2, the difference in usefulness
Bare wires do not contain any wires for insulation or maintenance. In addition to the wires that transmit electrical energy and information, they can also be used in the manufacture of electrical and electrical components and connections. Usually copper, aluminum, copper alloy, aluminum alloy. In addition, there are all kinds of insulated wires for special needs, such as low voltage wires for automobiles, front points for motors, motors, electrical appliances, wiring, air conductors, compensating wires, etc.. A cable used to transmit, distribute electrical energy, or transmit electrical signals. The cable can be divided into power cable, communication cable and control cable according to its use.
3, the layout of the difference
The difference between power cable and ordinary wire is mainly that the cable scale is larger and the layout is messy. The cable consists of the following 4 parts. Conductor wire: made of high conductivity materials. Insulating layer: insulation material used as a cable shall have high insulation resistance and high breakdown electric field strength. Cables are usually classified by insulation data.
In addition to the above differences, the cable also has significant advantages. Compared with the overhead line, cable line insulation strength is small spacing and small space occupation, laying underground without covering the space above, is not affected by environmental pollution, power supply reliability, the personal safety and the environment around the small trouble. Therefore, the cable is more and more used in densely populated areas and population and the network traffic congestion at busy. There is no disregard for modernization.
