1. The difference in materials
Wires are used to carry conductive metal wires. Available in various forms such as solid, stranded or foil braided.
According to the insulation condition, they are divided into two categories: bare wires and insulated wires.
A cable consists of one or more insulated conductors that are insulated from each other and placed within an insulated conductor formed in a sealed sheath.
A protective covering can be added to the outside.
The difference between wires and cables is that wires are generally smaller in size and simple in structure, but cables are sometimes classified as generalized wires.
2. Differences in use
Bare wire does not contain any insulation or protection of the wire.
In addition to being used as a conductor for transmitting electrical energy and information, it can also be used to make components and wires that connect motors and appliances.
Generally, copper, aluminum, copper, and aluminum alloys are used.
In addition, there are various insulated wires suitable for special requirements, such as low-voltage wires for automobiles, high-voltage ignition wires for automobiles, lead wires for electrical appliances, aviation wires, compensation wires, etc.
Cables are used to transmit, distribute, or convey electrical signals.
Cables can be divided into power cables, communication cables and control cables according to their uses.
3. Differences in structure
The main difference between power cables and ordinary wires lies in the larger size and complex structure of the cables.
The cable mainly consists of the following four groups.
Conductor Core: Made of highly conductive material.
Insulation: The insulation material used as a cable should have high insulation resistance and high breakdown electric field strength.
Insulation materials usually classify cables.
In addition to the above differences, cables offer significant advantages.
Compared with overhead lines, the advantages of cables are that the insulation distance between lines is small, the area is small, the underground laying does not occupy the above-ground area, and it is not affected by the pollution of the surrounding environment.
The power transmission has high reliability and does not interfere with personal safety and surrounding environment. small.
Therefore, cables are used in densely populated, densely populated areas and places with heavy traffic.
