Cable

A cable is two or more wires running side by side and bonded, twisted or braided together to form a single assembly.

Electric cables discussed here are mainly meant for installation in buildings and industrial sites. For power transmission at distances greater than a few kilometres see high voltage cable, power cables and HVDC.
