Product Details

This high quality oil-immersed transformer is available in a wide range of voltage levels including 20kV, 22kV and 33kV to suit different distribution system requirements. Whether your power grid is for residential, commercial or industrial use, this transformer provides the right voltage level to ensure the efficiency and stability of power transmission and distribution.

No-load regulation for precise voltage regulation

This transformer is equipped with the no load voltage regulation (NLTC) function, which can adjust the ratio of the transformer in the absence of load to realize precise voltage regulation. This design enables the transformer to maintain voltage stability when the load changes, avoiding the impact of voltage fluctuations on the stability of the power grid.
