Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, innovatively developed and produced by Chaotai Power, embodies exceptional performance with its low loss, minimal noise, and remarkable efficiency. These attributes contribute to its impressive energy-saving capabilities and pollution reduction. Unlike traditional oil-immersed transformers, this cutting-edge design eliminates the need for an oil conservator. Its advanced corrugated oil tank allows for automatic adjustment and compensation of oil volume changes through its flexible corrugated sheets. This unique feature keeps the transformer isolated from air, thereby significantly slowing down oil deterioration and insulation aging. The result is enhanced operational reliability, ensuring maintenance-free performance under standard operating conditions.

In cases where conditions deviate, we tailor the parameters in line with standards to maintain optimal performance.
Chaotai Power's fully sealed oil-immersed power transformer sets the standard with its low loss, minimal noise, and superior efficiency, delivering outstanding energy conservation and pollution reduction.
This advanced transformer, compared to ordinary oil-immersed models, innovates by eliminating the oil conservator, allowing oil volume changes to be automatically managed by the elasticity of the corrugated oil tank's sheets. By isolating the transformer from air exposure, the design dramatically mitigates oil degradation and insulation aging, enhancing operational reliability and negating the need for maintenance during regular operation.
