1. The structure is different, and the wires are generally composed of several soft wires with an insulation layer on the outside; And the cable is generally composed of one or several insulated wires, with the outer layer made of rubber.
2. Due to different sizes, wires are smaller in size, while cables are larger in size due to their complex structure.
3. The transmission capacity varies, with wires being able to transmit relatively small amounts of electricity and cables having strong load-bearing capacity.
4. The hardness is different, and the hardness of wires is not as high as that of cables.
Differences in materials
A conductive metal wire used to carry current. There are various forms such as solid, twisted, or foil woven. According to insulation status, it is divided into two categories: bare wires and insulated wires. A cable is an insulated conductor composed of one or more insulated conductive cores placed in a sealed sheath. It can be covered with a protective layer, and the difference between wires and cables is that the size of wires is generally small and the structure is relatively simple, but sometimes cables are also classified as generalized wires.
Differences in purpose
Bare wires are wires without any insulation or protective layer. In addition to being used as wires for transmitting electrical energy and information, it can also be used to manufacture components and connecting wires for motors and electrical appliances. Generally, copper, aluminum, copper alloys, 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, motor and electrical lead wires, aviation wires, compensation wires, etc. Cables are used for transmitting, distributing electrical energy, or transmitting electrical signals. Cables can be divided into power cables, communication cables, and control cables according to their purpose.
Differences in structure
The main difference between power cables and ordinary wires is their larger size and more complex structure. The cable mainly consists of the following four groups. Conductive core: made of high conductivity materials. Insulation layer: The insulation material used for cables should have high insulation resistance and high breakdown electric field strength. Cables are often classified by insulation materials.
