Product Description
Oil Immersed Series Transformer:
The S11-M series, a groundbreaking fully sealed oil immersed power transformer from Chaotai Power, stands out with its remarkable features of minimized loss, whisper-quiet operation, and superior efficiency. It is designed to deliver outstanding energy conservation while significantly cutting down on environmental pollutants. Distinct from standard oil-immersed transformers, this fully sealed marvel does away with the traditional oil conservator. Instead, it ingeniously regulates oil volume fluctuations using the elastic properties of its corrugated oil tank, thereby enhancing oil preservation and prolonging insulation life. The design ensures the transformer remains isolated from atmospheric air, reducing maintenance needs and boosting operational reliability.
