Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, proudly engineered and crafted by Chaotai Power, stands out with distinctive benefits such as reduced energy loss, minimal noise emissions, and superior efficiency. This design ensures exceptional energy conservation and pollution reduction. Differing from typical oil-immersed transformers, our fully sealed version eliminates the need for an oil conservator. It smartly auto-adjusts oil volume changes through the flexible corrugated sheets of the corrugated oil tank. This ingenious design isolates the transformer from air exposure, significantly decelerating oil degradation and insulation aging. It elevates operational reliability and eliminates the necessity for maintenance during standard operations.

Chaotai Power's fully sealed oil-immersed power transformers are crafted to offer low energy loss, quiet operation, and exceptional efficiency, promoting energy saving and minimizing environmental impact.
By eliminating the oil conservator, our fully sealed transformers use the elasticity of corrugated sheets in the oil tank to auto-adjust oil volume changes. This hermetic sealing prevents air contact, slowing oil degradation and insulation aging, enhancing reliability, and removing the need for maintenance under normal circumstances.
