Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil-immersed power transformer by Chaotai Power, meticulously designed to offer exceptional performance with low loss, minimal noise, and high efficiency. This transformer is an epitome of energy-saving, significantly reducing environmental pollution. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The oil volume adapts effortlessly, thanks to the flexible corrugated sheet in the oil tank, which automatically adjusts and compensates for changes. By being completely isolated from air, the transformer not only prevents and decelerates oil deterioration and insulation aging but also enhances operational reliability, ensuring maintenance-free performance under normal conditions.

Experience the innovation of Chaotai Power's fully sealed oil-immersed power transformers. Our transformers deliver outstanding performance with low energy loss, minimal noise, and high efficiency. They significantly contribute to energy conservation and pollution reduction.
Our advanced fully sealed transformer model surpasses traditional designs by eliminating the oil conservator. The transformer self-regulates oil volume changes through the elasticity of the corrugated oil tank's sheet. This design isolates the transformer from air exposure, effectively preventing and slowing down oil deterioration and insulation aging. It guarantees enhanced operational reliability and eliminates the need for maintenance during normal operations.
