Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series Fully Sealed Oil Immersed Power Transformer, meticulously crafted by Chaotai Power. This innovative transformer showcases unparalleled advantages of low loss, minimal noise, and high efficiency, offering remarkable energy-saving benefits while minimizing pollution. Distinguishing itself from conventional oil-immersed transformers, this fully sealed model eliminates the need for an oil conservator. The dynamic corrugated oil tank automatically compensates for oil volume changes through its flexible corrugated sheet. Isolated from atmospheric exposure, it robustly prevents oil deterioration and insulation aging, enhancing operational reliability, and eliminating the need for maintenance under normal conditions.
