Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series of fully sealed oil-immersed power transformers, a pinnacle of engineering excellence crafted by Chaotai Power. These transformers boast a groundbreaking design that ensures low energy loss, a whisper-quiet operation, and unparalleled efficiency, making them an ideal choice for energy conservation and environmental protection. Unlike traditional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The innovative design allows for automatic adjustment and compensation of oil volume through the flexible corrugated sheets of the oil tank, effectively isolating the transformer from air exposure. This clever design significantly slows oil deterioration and insulation aging, thereby enhancing operational reliability and minimizing maintenance needs during regular service.

Chaotai Power's fully sealed oil-immersed power transformer stands out for its low-loss, ultra-quiet, and highly efficient design, contributing to significant energy savings and reduced environmental impact.
In contrast to conventional oil-immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume's fluctuation is managed through the corrugated oil tank's elasticity, ensuring complete isolation from air. This design innovation slows oil degradation and insulation aging, bolsters operational reliability, and diminishes regular maintenance demands.
