Product Description



Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, expertly crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This remarkable transformer is distinguished by its superior low energy loss, whisper-quiet operation, and unparalleled efficiency. Embodying the essence of energy efficiency, it significantly reduces pollution and minimizes environmental impact. Unlike traditional oil-immersed transformers, this state-of-the-art model eliminates the need for an oil conservator. The cleverly engineered corrugated oil tank dynamically self-regulates to manage oil volume changes, ensuring a perfectly sealed environment that shields the transformer from air exposure. This innovative feature effectively prevents oil degradation, extends the lifespan of insulation materials, and greatly boosts operational reliability—all while requiring no regular maintenance under standard conditions.
