A cable is a conductor or a set of electrical conductors covered by an insulating material, designed to transmit electrical energy, communication signals, or data from one point to another.
Basic components of a cable:
1. Conductor: Usually made of copper or aluminum, it carries electricity or signals.
2. Insulation: A coating that prevents electricity from escaping and protects against short circuits.
3. Protective layer (optional): In industrial or outdoor cables, there may be shielding, outer jackets, armoring, etc., to protect against moisture, abrasion, electromagnetic interference, and more.
