Product Description
Oil immersed series transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer by Chaotai Power! This innovation is designed to offer remarkable benefits such as low loss, minimal noise, and outstanding efficiency, ensuring significant energy savings and reduced environmental impact. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the necessity for an oil conservator. The oil volume changes are seamlessly managed and compensated by the elastic corrugated sheet within the corrugated oil tank. This clever design ensures the transformer is completely isolated from the air, effectively preventing oil degradation and insulation aging, thereby enhancing operational reliability and negating the need for maintenance during standard operation.

Our fully sealed oil-immersed power transformer by Chaotai Power stands out with its low loss, low noise, and high efficiency, significantly contributing to energy conservation and pollution reduction.
In comparison to standard oil-immersed transformers, our fully sealed variant eliminates the need for an oil conservator. It autonomously adjusts oil volume through the elasticity of the corrugated oil tank sheets. This isolation from air effectively prevents oil degradation and insulation wear, boosting operational reliability and negating maintenance during normal usage.
