Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer masterfully engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This extraordinary transformer is distinguished by its outstanding features, including low energy loss, whisper-quiet operation, and exceptional efficiency. It serves as the epitome of an energy-saving solution, dramatically decreasing pollution and lessening the environmental footprint. Diverging from conventional oil-immersed transformers, this cutting-edge model does away with the oil conservator. Ingeniously designed to autonomously adapt and compensate for oil volume variations, the corrugated oil tank’s elasticity ensures the transformer remains perfectly sealed from air exposure. This groundbreaking design not only thwarts oil degradation and decelerates insulation aging but also significantly boosts operational reliability, eliminating the necessity for maintenance under typical operational conditions.
