1. Discrepancies in data
Wires: Conductive metal wires used to carry electric current. Available in solid, various forms such as stranded or foil braided. According to the insulation conditions, it can be divided into bare wire and insulated wire. The cable consists of one or more insulated conductors with the cores in a sealed jacket. The difference between wire and cable is that the wire is usually smaller in size and has a more sketchy layout, but sometimes the cable is placed on a generalized wire.
2. Use Differences
Bare wires that do not contain any insulation or maintenance layer. In addition to wires used to transmit electrical energy and information, they can also be used to make motors, building blocks and connecting wires for electrical appliances. Copper, aluminum, copper alloy are usually used, in addition, there are various insulated wires for special needs, low-voltage wires are used in automobiles, the front is the automotive high-voltage point, motor electrical leads, aviation wires, compensation wires, etc. Cables are used to transmit, distribute electrical energy, or transmit electrical signals. According to their use, cables can be divided into power cables, communication cables, and control cables, among others.
3. Different layouts
The difference between wires and cables and ordinary wires is mainly that the cable is large in scale and has a messy layout. The cable is mainly composed of the following four groups. Wire core: Made from high conductivity data. The insulating material used as a cable should have high insulation resistance and high breakdown field strength. Cables are usually classified by insulating material.
In addition to the above differences, cables offer significant advantages. Compared with overhead lines, the advantages of cables are that the insulation interval between the lines is small, the space occupied is small, the underground laying does not occupy the space on the ground, it is not affected by the pollution of the surrounding environment, the power supply reliability is high, and the interference to personal safety and the surrounding environment is small. Cables are mainly used in densely populated areas, densely populated power grids and places with heavy traffic congestion. The effect of modernization cannot be ignored.
