Product Description
Oil Immersed Series Transformer:
The S11-M series is a state-of-the-art, fully sealed oil-immersed power transformer proudly engineered by Chaotai Power. It boasts remarkable benefits such as significantly reduced loss, minimal noise, and superior energy efficiency, all contributing to an outstanding energy-saving performance and environmental preservation. Unlike standard models, this advanced transformer eliminates the need for an oil conservator. Instead, it innovatively uses the flexible corrugated sheet of its oil tank to automatically adjust and compensate oil volume changes. This design ensures that the transformer is hermetically sealed from the atmosphere, effectively protecting and prolonging the lifespan of the oil and insulation materials, thereby enhancing operational reliability and negating the necessity for routine maintenance under normal working conditions.

Our fully sealed oil-immersed power transformer by Chaotai Power stands out with its low loss, minimal noise, and exceptional efficiency, driving significant energy savings and reducing environmental impact.
In contrast to conventional oil-immersed transformers, our fully sealed model eliminates the oil conservator, relying instead on the corrugated oil tank's flexible sheet to self-adjust oil volume. This design innovation isolates the transformer from atmospheric exposure, thereby decelerating oil degradation and insulation aging, enhancing reliability, and minimizing the need for regular maintenance under standard operating conditions.
