Product Description



Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, masterfully crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. Esteemed for its exceptionally low energy loss, whisper-quiet operation, and unparalleled efficiency, this transformer is a beacon of energy conservation. It significantly reduces pollution while minimizing its environmental footprint. Departing from traditional oil-immersed transformers, this state-of-the-art model eliminates the oil conservator.
