Product Description
Oil immersed series transformer:
Introducing the S11-M series fully sealed oil immersed power transformer by Chaotai Power, a pinnacle of advanced technology and design. This transformer boasts exceptional attributes including low loss, minimal noise, and superior efficiency, delivering outstanding energy-saving benefits and minimizing environmental impact. Unlike conventional transformers, this fully sealed model eliminates the need for an oil conservator. Its intelligent design allows oil volume adjustments to occur automatically, courtesy of the corrugated oil tank's elastic corrugated sheet. This innovative feature ensures the transformer remains isolated from air, effectively preventing oil deterioration and insulation aging. The result is heightened operational reliability and a maintenance-free experience under normal conditions.
