Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, masterfully developed by Chaotai Power. This ingenious transformer stands out with its remarkable attributes of low loss, minimal noise, and superior efficiency, ensuring exceptional energy conservation and minimized pollution. Distinguishing itself from conventional oil-immersed counterparts, this innovative transformer eliminates the oil conservator. The oil volume adjustments are seamlessly managed by the flexible corrugated sheet of the tank, maintaining isolation from air. This design innovation not only prevents oil degradation and insulation aging but also significantly boosts operational reliability, ensuring maintenance-free performance under standard conditions.
