Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a state-of-the-art, fully sealed oil immersed power transformer crafted by Chaotai Power. This transformer is engineered with cutting-edge technology to offer remarkable benefits like low loss, minimal noise, and superior efficiency. Such features not only promote significant energy savings but also contribute to environmental conservation by reducing pollution. Departing from traditional designs, this fully sealed transformer eliminates the need for an oil conservator. It ingeniously utilizes the corrugated oil tank's elasticity to automatically adjust and compensate for oil volume changes. This innovation keeps the transformer isolated from air, thereby retarding oil degradation and insulation aging. The outcome is enhanced operational reliability and a maintenance-free experience during normal operations.
