Product Description
Oil Immersed Series Transformer:
Introducing the revolutionary S11-M series fully sealed oil-immersed power transformer, expertly crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This trailblazing transformer sets new standards with its strikingly low energy loss rate, ultra-quiet operation, and unparalleled efficiency. As a benchmark in energy conservation, it significantly curtails pollution and diminishes environmental impact. Unlike conventional oil-immersed transformers, this avant-garde model does away with the need for an oil conservator. Leveraging the innovative elasticity of the corrugated oil tank, it autonomously regulates and compensates for oil volume variations, maintaining an impeccably sealed environment that protects the transformer from air exposure. This game-changing feature effectively prevents oil degradation, substantially extends insulation life, and considerably enhances operational reliability—all without necessitating routine maintenance during regular use.
