Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series of fully sealed oil immersed power transformers, masterfully crafted by Chaotai Power. These transformers offer outstanding features such as low loss, minimal noise, and exceptional efficiency, ensuring remarkable energy-saving performance and diminished environmental impact. Unlike conventional oil immersed transformers, our advanced fully sealed design eliminates the need for an oil conservator. The adaptable corrugated sheet within the oil tank automatically adjusts the oil volume changes, safeguarding the transformer from air exposure. This innovative approach significantly retards oil deterioration and insulation aging, boosts operational reliability, and negates the necessity for routine maintenance.
