Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer developed by Chaotai Power. This cutting-edge solution boasts remarkable advantages including low loss, minimized noise, and superior efficiency, making it an ideal choice for energy saving and pollution reduction. Unlike ordinary oil-immersed transformers, our innovative design eliminates the need for an oil conservator. The oil volume changes are seamlessly adjusted and compensated by the flexibility of the corrugated oil tank. This advanced system is isolated from air exposure, effectively preventing oil degradation and insulation aging, ensuring enhanced operational reliability and eliminating the need for maintenance during regular operation.
