Internationally, a high voltage (HV) AC transmission system is anywhere between 35 to 220 kilovolt (kV), while extra high voltage (EHV) ranges from 330 to 750 kV.2 In China, the HV AC system includes both 110 kV and 220 kV transmission lines, while the

UHV Power Transmission

The alternating current (AC) transmission voltage classes are usually classified into high voltage (HV), extra-high voltage (EHV), and ultra-high voltage (UHV). Internationally, HV usually refers to a nominal voltage from 35 kV to 220 kV, EHV from 330 kV to below 1000 kV, and UHV 1000 kV and above.
