Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a masterpiece of engineering by Chaotai Power, our fully sealed oil-immersed power transformers boast unparalleled advantages. With their superior low-loss design, minimal noise, and high efficiency, these transformers promise exceptional energy-saving performance and significantly reduce pollution. Unlike conventional oil-immersed transformers, our innovative fully sealed design eliminates the need for an oil conservator. This unique configuration allows for automatic adjustment and compensation of oil volume, thanks to the elasticity of the corrugated oil tank, effectively isolating the transformer from air. This exceptional feature prevents oil deterioration and insulation aging, enhancing operational reliability and eliminating the need for maintenance during normal operation.

Our fully sealed oil-immersed power transformers by Chaotai Power set a new standard with their low-loss, low-noise, and high-efficiency features, significantly boosting energy-saving outcomes while minimizing environmental impact.
This advanced fully sealed design overhauls traditional oil-immersed transformers by forgoing the oil conservator. The intelligent design ensures the oil tank's corrugated sheet automatically adjusts for oil volume changes, effectively isolating the transformer from external air. This innovation curtails oil degradation and insulation wear, enhancing reliability and negating routine maintenance needs.
