Box-type substation

Outdoor American-style prefabricated substation

The YB-12/0.4 prefabricated substation integrates high-voltage control, protection, and voltage transformation functions and is widely used in power grids. The high-voltage load switch and high-voltage fuses are housed within the substation's oil-immersed transformer, with structural configurations available in either a shared-tank or separate-tank design. The tank features a fully sealed structure and is equipped with components for monitoring transformer operation, such as an oil temperature gauge, oil level indicator, pressure gauge, pressure relief valve, and oil drain valve.
