Generally speaking, there is no strict boundary between "wires" and "cables", and there is no precise and fixed conceptual distinction. They are usually distinguished only through daily experience. The difference between
wires and cables is that wires are usually smaller in size and simpler in structure, but cables are sometimes included in the broader category of wires. In a narrow sense, they are divided into wires and cables, and in a broad sense, they are collectively called cables. So what is the difference between wires and cables? Today Huaqiang Cable will take you to find out.
Simply put, a wire consists of one or more flexible wires covered with a soft sheath, and a cable consists of one or more insulated wires covered with a tough metal or rubber sheath.
Wires and cables generally consist of three parts: core wire, insulation sleeve and protective sleeve. Each conductor of a cable counts as a strand. This is the most direct difference between wires and cables. Of course, there are also differences in the following three aspects. The difference between
01 and materials
wires are metal wires used to conduct electricity and are used to transport current. They come in many forms such as solid, twisted or foil woven. According to the insulated metal, it is divided into two categories: bare wires and insulated wires. Insulated wire consists of one or more insulated wire cores placed in a sealed sheath. The difference between wires and cables is that wires are generally smaller in size and simpler in structure, but cables are sometimes classified as generalized wires. The difference between
02 and structures. The difference between
cables and ordinary wires lies in the large size and complex structure of the cables. Cables are mainly made of conductive cores (high conductivity materials). The insulation layer used as cable insulation material should have high insulation resistance and high breakdown electric field strength. Cables are generally classified as insulating materials. The difference between
03 and uses
bare wires wires that do not include any insulation or protective layer. In addition to being used as wires for transmitting electrical energy and information, they can also be used to manufacture components and connecting wires for motors and electrical appliances. In addition, there are various insulated wires suitable for special requirements, such as low-voltage wires for automobiles, high-voltage ignition wires for automobiles, leads for motors, aviation wires, compensation wires, etc. According to the purpose, the cables can be divided into power cables , communication cables and control cables.
In addition to the above differences, cables have obvious advantages. Compared with overhead lines, the advantages of cables are small horizontal insulation distance between lines, small floor space, underground laying does not occupy development space above the ground, and high power transmission reliability. Therefore, most cables are used in densely populated and grid-intensive areas and crowded places, and they play an important role in modern construction.
The above is the relevant content about the difference between wires and cables in this issue. Finally, Huaqiang Cable reminds everyone that when purchasing wires and cables, you must look for regular manufacturers and check the quality. Do not buy some unqualified wires because they are cheap to avoid accidents and damage to people and property.
