Product Description
Oil immersed series transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer by Chaotai Power, engineered for exceptional performance. This innovative transformer boasts low loss, minimal noise, and superior efficiency, providing a remarkable energy-saving solution while curtailing pollution. Distinct from conventional oil-immersed transformers, this fully sealed marvel eliminates the need for an oil conservator. The dynamic oil volume is automatically adjusted and compensated by the corrugated sheet's elasticity within the sophisticated corrugated oil tank. This design ensures total isolation from air, effectively preventing and decelerating oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during standard operations.
