Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a revolutionary fully sealed oil immersed power transformer from Chaotai Power. This advanced transformer boasts remarkable features such as low loss, minimal noise, and exceptional efficiency, ensuring optimal energy-saving performance and a significant reduction in pollution. Unlike conventional oil immersed transformers, our fully sealed model innovatively eliminates the need for an oil conservator. The adaptable corrugated oil tank automatically adjusts and compensates for changes in oil volume, safeguarding the system by isolating it from air exposure. This design effectively prevents oil deterioration and insulation aging, dramatically enhancing operational reliability while eliminating the need for regular maintenance.
