Product Description
Oil Immersed Series Transformer:
Introducing the state-of-the-art S11-M series fully sealed oil-immersed power transformer, a masterpiece crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This outstanding transformer is celebrated for its significantly reduced energy loss, whisper-quiet operation, and unparalleled efficiency. As a beacon of energy efficiency, it dramatically cuts down on pollution and minimizes environmental footprint. Departing from traditional oil-immersed transformers, this advanced model eliminates the necessity for an oil conservator. The cleverly engineered corrugated oil tank autonomously adapts to oil volume variations, maintaining a perfectly sealed environment that shields the transformer from air ingress. This pioneering feature effectively prevents oil degradation, extensively extends the life of insulation materials, and greatly boosts operational reliability—all while requiring no maintenance under normal operating conditions.
