Product Description
Oil Immersed Series Transformer:
The S11-M series, a premium fully sealed oil immersed power transformer by Chaotai Power, boasts remarkable features such as minimal loss, whisper-quiet operation, and exceptional efficiency. These attributes contribute to significant energy conservation while mitigating environmental impact. Unlike conventional oil immersed transformers, this innovative fully sealed version eliminates the need for an oil conservator. It ingeniously adjusts and compensates changes in oil volume through the elasticity of its corrugated sheet tank, isolating the transformer from the atmosphere. This design innovation slows oil degradation and insulation aging, heightening reliability and minimizing maintenance under standard operations.
