Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, developed and meticulously crafted by Chaotai Power. This remarkable transformer is engineered for excellence with features like low loss, minimal noise, and high efficiency, culminating in a superior energy-saving effect while significantly reducing pollution. In comparison to traditional oil immersed transformers, our fully sealed variant eliminates the need for an oil conservator. The oil volume adjustments are seamlessly managed by the elasticity of the corrugated sheet within the corrugated oil tank. This design innovation isolates the transformer from air exposure, effectively preventing and decelerating oil deterioration and insulation aging. The result is enhanced operational reliability and a maintenance-free experience during standard operations.
