Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series: Chaotai Power’s fully sealed oil-immersed power transformer that stands as a paragon of innovation and efficiency. Boasting reduced loss, minimal noise, and exceptional efficiency, this transformer promises unparalleled energy savings and a marked reduction in pollution. Unlike traditional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. Instead, it ingeniously adapts to oil volume changes through the flexible corrugated sheet design in the oil tank, isolating from air to retard oil degradation and insulation aging. This ensures superior operational reliability, virtually maintenance-free under normal conditions.
