Distribution voltages are not standardized globally due to historical infrastructure development and different electrical standards. For example, in the United States, common primary distribution voltages are 12.47 kV and 34.5 kV, while in China and Europe, voltages like 10 kV, 20 kV, and 35 kV are common. These differences are a result of historical decisions, population density, and network designs. Our equipment is designed to be versatile and compatible with a wide range of these international standards.
