Product Description
Oil Immersed Series Transformer:
Introducing the revolutionary S11-M series fully sealed oil-immersed power transformer, meticulously crafted and expertly engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional transformer is celebrated for its remarkable attributes such as exceptionally low energy loss, whisper-quiet operation, and outstanding efficiency. It exemplifies energy conservation, significantly slashing pollution and curtailing environmental footprint. Departing from conventional oil-immersed transformers, this state-of-the-art model abolishes the need for an oil conservator. By harnessing the innovative elasticity of the corrugated oil tank, it autonomously regulates and compensates for oil volume variations, maintaining a perfectly sealed environment to protect the transformer from air exposure. This transformative feature effectively hinders oil degradation, significantly prolongs insulation lifespan, and dramatically boosts operational reliability—all without necessitating routine maintenance during standard use.
