Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, expertly crafted by Chaotai Power, stands out with its remarkable low loss, ultra-quiet operation, and exceptional efficiency. This innovative design ensures significant energy savings and minimized environmental impact. Unlike the conventional oil immersed transformers, this state-of-the-art model eliminates the need for an oil conservator. The corrugated oil tank's elastic corrugated sheet automatically adjusts and compensates for oil volume changes, ensuring the transformer remains isolated from air. This design innovation helps prevent oil deterioration and insulation aging, boosting operational reliability while eliminating the need for maintenance during standard operation.

Chaotai Power's fully sealed oil immersed transformers are engineered for low loss, whisper-quiet operation, and outstanding efficiency, forming a cornerstone of energy conservation and pollution reduction.
In contrast to standard oil immersed transformers, our advanced fully sealed model eliminates the conventional oil conservator. This innovative feature leverages the corrugated oil tank's flexible sheet to autonomously manage oil volume changes, shielding the transformer from air exposure. This isolation aids in decelerating oil deterioration and insulation aging, which significantly enhances operational reliability and negates the need for maintenance during typical use.
