Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series: a fully sealed oil-immersed power transformer, crafted by Chaotai Power. This innovation blends superior efficiency with remarkable noise reduction and minimal energy loss for an impressive energy-saving performance. Unlike conventional oil-immersed transformers, this model foregoes the oil conservator, with variations in oil volume seamlessly managed by the corrugated oil tank's elasticity. The sealed design guards the transformer from air exposure, slowing oil deterioration and insulation aging, which enhances operational reliability and eliminates the need for routine maintenance.
