Product Description
Oil Immersed Series Transformer:
Introducing the avant-garde S11-M series fully sealed oil-immersed power transformer, expertly crafted by Zhejiang Chaotai Complete Equipment Co., Ltd. This marvel of engineering stands out with its astoundingly low energy loss, quiet performance, and unparalleled efficiency. It embodies the pinnacle of energy efficiency, significantly curtailing pollution while safeguarding our environment. Departing from traditional designs, this innovative transformer eliminates the need for an oil conservator, thanks to the clever elasticity of its corrugated oil tank.
