What are the differences between power cables and telecommunication cables?
Telecommunication cable: a cable used primarily for transmitting telephone, telegraph, facsimile documents, television and radio programs, data and other electrical signals. Twisted by one or more wires insulated from each other. Compared with the overhead of communication cable, communication capacity, transmission has the advantages of high stability, good secrecy, less affected by natural conditions and disturbance etc.. Generally, it can be divided into local communication cables, long distance symmetrical cables, coaxial cables, submarine cables, optical fiber cables, radio frequency cables and so on.
Power cables are cables used to transmit and distribute electrical energy. Commonly used in urban underground power grid, power station leads the line, the internal power supply of industrial and mining enterprises and the underwater transmission line across the river and the sea. In power systems, cable products are commonly used, including 1-500KV and above voltage levels, and various insulated power cables. The basic structure of the utility model is composed of four parts: a wire core (conductor), an insulating layer, a shielding layer and a protective layer. Generally buried in the soil or deposited in the interior, ditch, tunnel, line insulation distance is small, not tower, covering less, basically not occupy the ground space.
Power cables are strong electricity and have multilayer structure; communication cables are weak current and are many pairs of thin wires
