Product Description
Oil immersed series transformer:
The S11-M series fully sealed oil-immersed power transformer, a masterpiece from Chaotai Power, ushers in an era of superior performance with its remarkable attributes of low loss, minimal noise, and outstanding efficiency. This marvel not only ensures substantial energy savings but also contributes to a cleaner environment. Diverging from the conventional oil-immersed transformers, this advanced fully sealed variant eliminates the need for an oil conservator. It ingeniously manages oil volume through the flexible corrugated sheets of its tank, ensuring it remains hermetically sealed from air exposure. This innovative isolation significantly retards oil degradation and insulation wear, thereby bolstering reliability and negating the need for regular maintenance.
