Product Description



Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, exquisitely engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This transformative marvel is renowned for its ultra-low energy consumption, virtually silent operation, and unrivaled efficiency. A paradigm of energy conservation, it dramatically reduces pollution and minimizes environmental impact. Unlike conventional oil-immersed transformers, this cutting-edge model eliminates the necessity for an oil conservator. Its ingenious corrugated oil tank design autonomously self-adjusts to oil volume shifts, maintaining a perfectly sealed environment that shields the transformer from air exposure. This innovative feature effectively halts oil degradation, significantly prolongs insulation material lifespan, and vastly enhances operational dependability—all while eliminating the need for routine maintenance under standard conditions.
