Product Description
Oil-Immersed Series Transformer:
Introducing the S11-M series, a revolutionary fully sealed oil-immersed power transformer designed and meticulously crafted by Chaotai Power. This cutting-edge transformer boasts remarkable features like low loss, minimized noise, and exceptional efficiency, ensuring a superior energy-saving performance while significantly reducing environmental impact. Unlike traditional oil-immersed transformers, the fully sealed variant eliminates the need for an oil conservator. The oil volume adjustments are ingeniously handled through the elasticity of the corrugated sheets within the oil tank, isolating the unit from air exposure. This innovative design prevents oil degradation and insulation aging, boosts operational reliability, and negates the need for maintenance under standard operating conditions.
