Product Description
Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, engineered with precision and crafted with care by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional transformer stands out with its remarkable attributes, including extremely low energy loss, ultra-quiet functionality, and unparalleled efficiency. As a beacon of energy efficiency, it slashes pollution and curtails environmental impact. Innovatively departing from conventional oil-immersed transformers, this state-of-the-art model eliminates the need for an oil conservator. Leveraging the ingenious elasticity of the corrugated oil tank, it autonomously adjusts to oil volume fluctuations, preserving a perfectly sealed environment that protects the transformer from air exposure. This revolutionary feature effectively prevents oil degradation, extends the lifespan of insulation, and significantly enhances operational reliability—all while abolishing the need for routine maintenance during standard use.
