Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformers, meticulously developed by Zhejiang Chaotai Power. These transformers stand out with their remarkable low loss, minimal noise, and impressive high efficiency, paving the way for incredible energy-saving performance and pollution reduction. Unlike ordinary oil-immersed transformers, the fully sealed design eliminates the need for an oil conservator. The oil volume is ingeniously managed by the flexible corrugated sheet of the corrugated oil tank, automatically adjusting to changes. This design innovation isolates the transformer from air, effectively preventing oil deterioration and insulation aging, thus significantly boosting operational reliability and reducing the need for maintenance during normal operations.
