Low frequency voltage refers to the unified standard voltage of power industry and power equipment stipulated by the state.

Low Frequency: refers to the frequency of industrial AC power supply, unit Hertz (HZ)

China's single-phase power supply low frequency voltage, 50 Hz, 220 V. The low frequency voltage of three-phase power supply is 50Hz 380V. Because of the imbalance of industrial development and colonial control during World War II, there is no uniform standard for low frequency voltage in the world. There are great differences among different countries and regions. The following are the power-frequency voltage in different parts of the world.
