Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, meticulously crafted by Chaotai Power, is a revolutionary product that epitomizes excellence in efficiency and sustainability. Its standout features include minimal loss, whisper-quiet operation, and unparalleled efficiency, all contributing to a significant reduction in pollution and energy consumption. Unlike conventional oil-immersed transformers, this fully sealed marvel eliminates the need for an oil conservator. The innovative design allows for automatic adjustment and compensation of oil volume through the flexible corrugated sheet of the oil tank. Being completely isolated from air, it effectively prevents and decelerates oil deterioration and insulation aging, boosting operational reliability while requiring no maintenance during standard operations.

Chaotai Power's fully sealed oil-immersed power transformer offers a remarkable blend of low loss, low noise, and high efficiency, maximizing energy savings while minimizing ecological impact.
This innovative transformer, compared to traditional oil-immersed types, features a clever design that eliminates the oil conservator. The auto-adjusted and compensated oil volume, thanks to the corrugated tank sheet, ensures the transformer remains air-isolated, thereby mitigating oil degradation and insulation aging. This enhances reliability and negates the need for maintenance under normal operational conditions.
