Product Overview

Oil-immersed off-circuit power transformers are mainly used for urban and rural industrial & agricultural power grids, various industrial and mining enterprises, and power station transmission and distribution projects. Equipped with an off-circuit tap-changer, the transformer can only perform voltage regulation when de-energized. This transformer converts high-voltage grid power into low-voltage power suitable for enterprise and residential low-voltage circuits, and is generally deployed as a step-down transformer.
