Product Description
Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, crafted with precision and manufactured by the renowned Zhejiang Chaotai Complete Equipment Co., Ltd. This remarkable transformer is in a league of its own with features such as extraordinary low energy loss, exceptionally quiet operation, and unparalleled efficiency. It stands as a beacon of energy conservation, radically cutting pollution and reducing environmental impact. Unlike traditional oil-immersed transformers, this state-of-the-art model eliminates the need for an oil conservator. Thanks to the clever design of the corrugated oil tank, it autonomously adjusts and compensates for oil volume changes, preserving a perfectly sealed environment that safeguards the transformer from air exposure. This revolutionary feature actively prevents oil degradation, significantly prolongs the lifespan of insulation, and dramatically enhances operational reliability—all while avoiding the need for routine maintenance during its normal operation.
