Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, a remarkable innovation by Chaotai Power, stands distinguished with its low loss, minimized noise, and enhanced efficiency. This cutting-edge transformer promises a superior energy-saving impact while significantly reducing environmental pollution. Unlike conventional oil immersed transformers, this fully sealed variant eliminates the need for an oil conservator. The fluctuations in oil volume are expertly managed and automatically compensated by the flexible corrugated sheet within the oil tank. By being completely isolated from air exposure, the transformer effectively curbs oil deterioration and insulation aging, bolstering operational reliability and negating the need for regular maintenance.
