Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a marvel of engineering by Chaotai Power! This fully sealed oil-immersed power transformer boasts remarkable benefits such as low energy loss, whisper-quiet operation, and unparalleled efficiency. It not only promises exceptional energy-saving capabilities, but also significantly minimizes environmental impact. Unlike traditional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. The ingenious design allows for automatic adjustment and compensation of oil volume changes via the elastic corrugated sheet within the corrugated oil tank. This isolation from air prevents deterioration and aging of insulation, thereby enhancing operational reliability and ensuring maintenance-free performance under normal conditions.

Chaotai Power presents its fully sealed oil-immersed transformers, offering outstanding benefits such as reduced energy loss, minimal noise, and superior efficiency. These features deliver significant energy savings while reducing environmental impact.
Compared to conventional oil-immersed transformers, our fully sealed design eliminates the oil conservator. The oil volume changes are adeptly managed by the elasticity of corrugated sheets in the oil tank. This design prevents air contact, curbing the deterioration of oil and insulation, enhancing reliability, and ensuring maintenance-free operation.
