Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series of fully sealed oil-immersed power transformers, a groundbreaking innovation by Chaotai Power. These transformers offer exceptional benefits including reduced loss, minimized noise, and enhanced efficiency, yielding impressive energy-saving results and reducing environmental impact. Unlike traditional oil-immersed transformers, our fully sealed design eliminates the oil conservator, relying instead on the sophisticated elasticity of the corrugated oil tank to adjust and compensate for oil volume changes automatically. This cutting-edge technology ensures the transformer remains isolated from air, significantly slowing oil deterioration and insulation aging, thereby boosting operational reliability and eliminating the need for routine maintenance.
