Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer by Chaotai Power. This cutting-edge transformer stands out with its remarkable low loss, minimal noise, and superior efficiency. It delivers outstanding energy-saving benefits and significantly reduces environmental pollution. In contrast to standard oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. This innovation allows the oil volume to be automatically adjusted through the flexible corrugated sheet of its oil tank, ensuring optimal performance. The transformer's unique isolation from air effectively prevents oil deterioration and insulation aging, enhancing reliability and eliminating the need for maintenance during regular operation.
