Product Description



Oil Immersed Series Transformer:
Introducing the S11-M series, a pioneering fully sealed oil immersed power transformer from Chaotai Power. These transformers boast remarkable low loss, minimal noise, and exceptional efficiency, providing superior energy-saving capabilities while reducing environmental impact. What sets this transformer apart from traditional oil immersed models is the elimination of the oil conservator. Instead, the innovative design features a corrugated oil tank where changes in oil volume are managed by the tank's own elasticity. This design ensures the transformer remains isolated from air, thus significantly slowing oil deterioration and insulation aging. The result? Enhanced operational reliability and a maintenance-free performance under normal conditions.
