Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, a brainchild of Chaotai Power, stands out with its remarkable benefits of reduced loss, whisper-quiet operation, and superior efficiency. This results in impressive energy savings and a significant reduction in environmental impact. Unlike conventional oil-immersed transformers, this innovative model eliminates the need for an oil conservator. The oil volume changes are seamlessly adjusted and compensated through the corrugated oil tank's elastic properties. With this advanced design, the transformer remains shielded from air exposure, thus minimizing oil degradation and insulation aging. This enhancement not only boosts operational reliability but also eliminates the need for routine maintenance under normal conditions.

Our fully sealed oil-immersed power transformer from Chaotai Power boasts low-loss, low-noise, and high-efficiency features, ensuring exceptional energy conservation and reduced ecological footprint.
In contrast to traditional oil-immersed transformers, our fully sealed design eliminates the oil conservator. Instead, it utilizes the elasticity of the corrugated oil tank to automatically adjust oil volume changes. This design keeps the transformer isolated from air exposure, preventing oil degradation and insulation aging, enhancing reliability, and eliminating the need for routine maintenance during normal operations.
