The kilovolt (symbol: kV) is equal to 1,000 volts. It is used for high-voltage power transmission lines (typically 11–765 kV), X-ray tubes, and industrial power systems.
Volt
The volt (symbol: V) is the SI unit of electric potential (voltage). It is defined as the potential difference that drives a current of one ampere through a resistance of one ohm, or equivalently, one joule of energy per coulomb of charge. Named after Alessandro Volta.
