Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, a brilliant innovation by Chaotai Power. This advanced transformer offers outstanding benefits such as significantly reduced loss, minimized noise, and remarkable efficiency, resulting in substantial energy savings and pollution reduction. Unlike ordinary oil-immersed transformers, our cutting-edge design removes the need for an oil conservator. Instead, the transformer utilizes the elasticity of the corrugated sheet within its oil tank to automatically adjust and compensate for oil volume changes. This ingenious design isolates the transformer from air exposure, effectively preventing oil deterioration and insulation degradation, thereby enhancing operational reliability and allowing for maintenance-free normal operation.

The innovative fully sealed oil immersed power transformer by Chaotai Power stands out with its low loss, minimal noise, and exceptional efficiency, promoting energy conservation and minimizing pollution.
In comparison to conventional oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. The ingenious use of the corrugated sheet's elasticity in the oil tank allows for automatic adjustment of oil volume, keeping the transformer air-isolated. This design significantly curtails oil degradation and insulation aging, boosting operational reliability and eliminating the need for maintenance during standard operations.
