Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a revolutionary fully sealed oil-immersed power transformer by Chaotai Power. This state-of-the-art solution stands out with its exceptional low-loss, low-noise, and high-efficiency performance, delivering outstanding energy-saving benefits while significantly reducing pollution. Unlike conventional oil-immersed transformers, the fully sealed design eliminates the need for an oil conservator. The ingeniously engineered corrugated oil tank compensates for oil volume changes through its own elasticity, ensuring isolation from the air. This innovative approach prevents oil degradation and insulation aging, enhancing operational reliability and negating the need for maintenance during normal operations.

Chaotai Power presents a fully sealed oil-immersed transformer, renowned for its minimal loss, minimal noise, and high efficiency, which together provide exceptional energy savings and pollution reduction.
This innovative design, compared to ordinary oil-immersed transformers, eliminates the oil conservator. Oil volume changes are automatically managed by the flexible corrugated sheet design, keeping the transformer isolated from air exposure. This significantly slows down oil degradation and insulation aging, ensuring greater reliability and eliminating the need for regular maintenance.
