<P> Overhead power transmission lines are classified in the electrical power industry by the range of voltages: </P> <Ul> <Li> Low voltage (LV)--less than 1000 volts, used for connection between a residential or small commercial customer and the utility . </Li> <Li> Medium voltage (MV; distribution)--between 1000 volts (1 kV) and 69 kV, used for distribution in urban and rural areas . </Li> <Li> High voltage (HV; subtransmission less than 100 kV; subtransmission or transmission at voltages such as 115 kV and 138 kV), used for sub-transmission and transmission of bulk quantities of electric power and connection to very large consumers . </Li> <Li> Extra high voltage (EHV; transmission)--from 345 kV, up to about 800 kV, used for long distance, very high power transmission . </Li> <Li> Ultra high voltage (UHV)--higher than 800 kV . The Financial Times reported UHV lines are a "game changer", making a global electricity grid potentially feasible . StateGrid said that compared to conventional lines, UHV enables the transmission of five time more power, over six times the distance . </Li> </Ul> <Li> Low voltage (LV)--less than 1000 volts, used for connection between a residential or small commercial customer and the utility . </Li> <Li> Medium voltage (MV; distribution)--between 1000 volts (1 kV) and 69 kV, used for distribution in urban and rural areas . </Li>
