What's The Difference Between A Cable And A Wire?
Jul 17, 2017

The difference between-materials
A conductive metal wire used for carrying current. There are solid ﹑ twisted or foil-woven and other forms. According to the insulation status is divided into bare wires and insulated wire two major categories. A cable consists of an insulated conductor of one or more insulated conductors placed in a sealed sheath. It can be added to protect the cover layer, the difference between wire and cable is that the size of the wire is generally smaller, the structure is relatively simple, but sometimes the cable is also classified into a broad range of wires.

-Use Difference
Bare wires do not pack any insulated or protective wires. In addition to the transmission of electrical energy and information of the wire, can also be used to manufacture electrical ﹑ electrical components and connectors. General use of copper, aluminum, copper alloy, aluminum alloy. In addition, there are a variety of special requirements for insulating wires, such as automotive low-voltage wire, automotive high-voltage ignition line, electrical wiring, aviation wire, compensation wire. Cables are used to transmit, distribute, or transmit electrical signals. The cable can be divided into power cable, communication cable and control cable according to its use.

The difference of 3---structure
The main difference between power cable and ordinary wire is that the cable size is larger and the structure is complex. The cables are mainly composed of the following 4 subgroups.
Conductive wire Heart: made of high conductivity material. Insulating layer: Insulating material used as a cable shall have high insulation resistance and high breakdown electric field strength. Cables are often classified by insulating materials.

In addition to the above differences, the cable also has a clear advantage. Compared with the overhead line, the advantage of cable is that the insulation distance between the lines is small, the footprint is small, underground laying is not above the floor space, not affected by ambient pollution, high reliability of transmission, personal safety and the surrounding environment of small interference. As a result, the cables are applied to densely populated and densely populated areas and congested traffic. Has the function which cannot neglect to the modernization construction.
