A cable is an electrical energy or signal transmission device, usually consisting of several wires or groups of wires.
Definition 1: A wire made of one or more mutually insulated conductors and an outer insulating protective layer that transmits electricity or information from one place to another.
Definition 2: A rope-like cable usually made up of several or groups of wires (at least two in each group) twisted together, each of which is insulated from each other and is often twisted around a center, with a highly insulating covering on the entire outskirt. The cable has the characteristics of internal energizing and external insulation.
