Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil immersed power transformer crafted by Chaotai Power. This innovative transformer boasts significant advantages such as minimized energy loss, tranquil operation, and impressive efficiency. These features culminate in substantial energy savings and reduced environmental impact. Unlike traditional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. It ingeniously uses the flexibility of its corrugated oil tank to automatically adjust and compensate for changes in oil volume. By being completely sealed from the atmosphere, the transformer significantly slows the aging of its insulation and deterioration of the oil, thereby increasing operational reliability and eliminating maintenance during standard use.

The fully sealed oil immersed power transformer, innovatively developed by Chaotai Power, exemplifies excellence with its low loss, quiet operation, and superior efficiency, ensuring remarkable energy savings and reduced environmental impact.
In contrast to traditional oil-immersed models, this fully sealed transformer eliminates the need for an oil conservator. It adeptly adjusts and compensates for oil volume changes through the elasticity of its corrugated oil tank. The design effectively seals the transformer from atmospheric exposure, significantly diminishing oil degradation and insulation aging, thereby enhancing operational reliability and negating the necessity for regular maintenance.
