Product Description
Oil Immersed Series Transformer:
Unveiling the revolutionary S11-M series fully sealed oil-immersed power transformer, meticulously engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional transformer stands out with its incredibly low energy loss, virtually silent operations, and outstanding efficiency. It is a paragon of energy efficiency, dramatically reducing pollution and lessening environmental impact. Unlike conventional oil-immersed transformers, this cutting-edge model does away with the necessity of an oil conservator. The ingenious design of the corrugated oil tank autonomously adjusts and compensates for oil volume fluctuations, maintaining an impeccably sealed environment that shields the transformer from air exposure. This avant-garde feature effectively curtails oil degradation, significantly extends the lifespan of insulation materials, and enhances operational reliability—all while obviating the need for routine maintenance under standard conditions.
