Product Description
Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, crafted with precision and innovation by Zhejiang Chaotai Complete Equipment Co., Ltd. This remarkable transformer distinguishes itself with its exceptionally low energy loss, whisper-quiet performance, and unparalleled efficiency. It stands as a beacon of energy conservation, significantly cutting pollution and reducing environmental footprints. Unlike traditional oil-immersed transformers, this state-of-the-art model eliminates the need for an oil conservator. Thanks to the clever design of the corrugated oil tank, it self-regulates and compensates for oil volume changes, ensuring a perfectly sealed environment that protects the transformer from air exposure. This pioneering feature effectively prevents oil degradation, greatly extends the life of insulation materials, and significantly boosts operational reliability—all while requiring no routine maintenance under normal conditions.
