Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil immersed power transformer crafted by Chaotai Power. This marvel of engineering boasts low loss, operates with minimal noise, and offers high efficiency, all contributing to a remarkable energy-saving effect while minimizing environmental impact. Distinct from conventional oil-immersed transformers, our fully sealed variant eliminates the need for an oil conservator; instead, the oil volume adjustments are seamlessly managed and compensated through the unique elasticity of the corrugated oil tank. This innovative design ensures the transformer remains isolated from air exposure, effectively preventing oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during normal operation.

Our fully sealed oil immersed power transformer, proudly developed by Chaotai Power, is designed with low loss and noise, coupled with high efficiency, ensuring significant energy savings and reduced pollution. A true testament to sustainable engineering.
Designed to outshine ordinary oil-immersed transformers, our fully sealed variant smartly does away with the traditional oil conservator. The volume changes in oil are effortlessly managed through the corrugated sheet's elasticity within the oil tank. By isolating the transformer from air exposure, it remarkably slows down oil deterioration and insulation aging, enhancing operational reliability and eliminating maintenance in routine operations.
