Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series: the pinnacle of innovation brought to you by Chaotai Power. This fully sealed oil-immersed power transformer is a marvel of modern engineering, boasting a trifecta of low loss, whisper-quiet operation, and unparalleled efficiency. It serves as a beacon of energy conservation, reducing pollution while enhancing environmental sustainability. Diverging from traditional designs, this transformer eliminates the need for an oil conservator. Instead, it ingeniously employs the elasticity of its corrugated oil tank to automatically adapt and compensate for oil volume fluctuations. This strategic isolation from air significantly mitigates oil degradation and insulation aging, thereby boosting operational reliability and minimizing the need for maintenance under normal operations.
