Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer – a testament to cutting-edge innovation by Chaotai Power. This state-of-the-art transformer is engineered to deliver unparalleled performance with its low loss, low noise, and high efficiency, achieving remarkable energy-saving benefits while minimizing environmental impact. Unlike conventional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. Its unique design features an automatic oil volume adjustment and compensation system, courtesy of the corrugated sheet's elasticity within the oil tank. This groundbreaking isolation from air effectively curtails oil deterioration and insulation aging, thereby significantly boosting operational reliability and reducing maintenance needs during regular operation.
