Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, developed and produced by Chaotai Power, stands out with its remarkable features of low loss, low noise, and high efficiency. This innovation ensures a superior energy-saving effect while significantly reducing pollution. Unlike ordinary oil-immersed transformers, this fully sealed transformer eliminates the need for an oil conservator. The fluctuation in oil volume is ingeniously managed and balanced by the flexible corrugated sheet of the oil tank, ensuring consistent performance. Being completely isolated from air, it effectively curtails the deterioration of the oil and slows insulation aging, which elevates operational reliability and negates the need for maintenance during regular operation.
