Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, a state-of-the-art creation by Chaotai Power, boasts remarkable benefits such as minimal loss, reduced noise, and heightened efficiency. This innovative design ensures substantial energy-saving outcomes and cuts down on pollution. Unlike conventional oil-immersed transformers, this fully sealed version eliminates the need for an oil conservator. The ingenious corrugated oil tank automatically adjusts and compensates for oil volume changes through its elastic corrugated sheet, ensuring isolation from air exposure. This not only prevents and decelerates oil deterioration and insulation aging but also significantly boosts operational reliability, all while eliminating the need for maintenance during standard operations.

The fully sealed oil-immersed transformer by Chaotai Power offers unparalleled advantages, including low loss, quiet performance, and exceptional efficiency, leading to significant energy savings and pollution reduction.
This advanced transformer design stands apart from ordinary models by eliminating the oil conservator. The corrugated sheet within the oil tank adapts to oil volume changes, maintaining isolation from the air. This feature prevents oil degradation and insulation aging, enhances reliability, and negates the need for maintenance under typical operating conditions.
