Product Description
Oil Immersed Series Transformer: Witness the future of power transformation with our Oil Immersed Series Transformer, where advanced engineering meets practicality. This series marks a significant leap in transformer technology, designed to deliver superior performance with unwavering reliability.
The S11-M series of fully sealed oil-immersed power transformers from Chaotai Power are meticulously engineered to offer outstanding benefits such as low energy loss, minimal noise, and superior efficiency. These features collectively foster excellent energy-saving outcomes while significantly curtailing environmental pollution. Unlike conventional oil-immersed transformers, this innovative fully sealed design eliminates the need for an oil conservator. The ingenious design automatically adjusts and compensates oil volume variations via the flexible corrugated sheet of the corrugated oil tank. This isolation from air ensures the retardation of oil degradation and insulation aging, thereby enhancing operational reliability and negating the need for routine maintenance.
