Product Description
Oil Immersed Series Transformer:
The S11-M series, a fully sealed oil-immersed power transformer by Chaotai Power, is engineered for superior performance. It boasts low loss, minimal noise, and high efficiency, delivering exceptional energy savings and reducing environmental impact. Unlike conventional models, this transformer eliminates the need for an oil conservator. The innovative design features a corrugated oil tank, where oil volume changes are self-regulated by the tank's elasticity. This isolation from air combats oil deterioration and insulation aging, thus enhancing reliability and diminishing the need for maintenance during regular operations.

Chaotai Power's fully sealed oil-immersed power transformer stands out with its low loss, quiet operation, and high efficiency, providing substantial energy savings and minimizing environmental impact.
Compared to conventional oil-immersed transformers, this fully sealed model eliminates the oil conservator. It features a corrugated oil tank where oil volume is self-adjusted through the tank's elasticity. This design isolates the transformer from air, preventing oil degradation and insulation aging, thus increasing operational reliability and reducing maintenance needs during normal use.
