Product Description
Oil Immersed Series Transformer:
The S11-M series is a masterpiece of innovation and efficiency. This fully sealed, oil-immersed power transformer, meticulously crafted by Chaotai Power, boasts remarkable features such as minimal energy loss, whisper-quiet operation, and outstanding efficiency. These attributes collectively contribute to a substantial reduction in pollution, achieving significant energy savings. Distinct from conventional oil-immersed transformers, this model eliminates the need for an oil conservator. The dynamic oil volume is ingeniously regulated and automatically balanced by the flexible corrugated sheet design of its oil tank. This innovative design ensures the transformer remains sealed from atmospheric contact, effectively delaying oil degradation and insulation aging. As a result, operational reliability is significantly enhanced, and regular maintenance becomes a thing of the past.

This fully sealed oil-immersed power transformer by Chaotai Power exemplifies minimal loss, low noise, and superior efficiency. It effectively conserves energy while minimizing pollution.
In contrast to conventional models, this fully sealed transformer eliminates the oil conservator, with oil volume dynamically managed through the elasticity of its corrugated oil tank. Isolation from air mitigates oil and insulation degradation, boosting reliability and negating regular maintenance.
