Product Description
Oil Immersed Series Transformer:
The S11-M series, a fully sealed oil-immersed power transformer crafted by Chaotai Power, stands out with its remarkable low loss, minimal noise, and superior efficiency. This technological marvel not only delivers outstanding energy-saving benefits but also significantly reduces environmental pollution. Unlike the conventional oil-immersed transformers, our fully sealed version eliminates the oil conservator, leveraging the resilience of the corrugated oil tank's sheet to automatically regulate and compensate for oil volume changes. By isolating the transformer from air exposure, we effectively decelerate oil degradation and insulation aging, thereby boosting operational reliability and eliminating the need for routine maintenance.

The fully sealed oil-immersed power transformer developed by Chaotai Power offers exceptional advantages such as reduced loss, minimized noise, and high efficiency, providing excellent energy savings and pollution reduction.
In contrast to traditional oil-immersed transformers, this fully sealed model eliminates the need for an oil conservator and employs the elasticity of the corrugated oil tank's sheet to automatically adjust and compensate for changes in oil volume. The transformer is shielded from air exposure, preventing and slowing oil degradation and insulation aging, enhancing operational reliability, and eliminating the need for maintenance during normal operation.
