Box Dry Transformer is a heavy duty electrical machine that can be used in various industrial as well as commercial electrically powered systems. It is designed as per the electrical engineering standards that result in high working efficiency and robustness. It is free from insulating liquid and the coils of this unit are sealed in a pressurized air tank. Box Dry Transformer is in high demand due to its high robustness and excellent resistance against overheating that greatly reduces the risk of explosions.
