Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series Fully Sealed Oil Immersed Power Transformer, masterfully engineered by Chaotai Power. This remarkable transformer stands out with its ultra-low loss, whisper-quiet operation, and unparalleled efficiency. It is a beacon of energy conservation, significantly reducing environmental impact. Unlike conventional oil-immersed transformers, the fully sealed design eliminates the need for an oil conservator. This innovation allows automatic oil volume adjustments, thanks to the flexible corrugated oil tank sheets. The design ensures the transformer remains isolated from air, slowing down oil degradation and insulation aging. Resulting in enhanced operational reliability and minimal maintenance, the transformer is built for seamless performance under normal conditions.

The fully sealed oil-immersed power transformer by Chaotai Power is characterized by its low loss, minimal noise, and exceptional efficiency. This translates to substantial energy savings and reduced environmental pollution.
This advanced transformer design, in contrast to traditional oil-immersed transformers, does away with the oil conservator. The elasticity of the corrugated oil tank sheets allows for automatic oil volume adjustment. This isolation from air helps decelerate oil degradation and insulation aging, boosting operational reliability and reducing maintenance needs during normal operations.
