A power cable is an electrical cable designed to carry electrical power from one point to another. It typically consists of one or more conductors, which are insulated to prevent electrical shock and short circuits. Power cables are used in various applications, including residential wiring, industrial machinery, and electrical distribution systems. These cables come in different sizes and types, depending on their intended use. For example, AC power cables are used for alternating current, while DC power cables are used for direct current. Proper selection and installation of power cables are essential for safety and efficiency in electrical systems.
