Product Description
Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, masterfully crafted and innovatively designed by Zhejiang Chaotai Complete Equipment Co., Ltd. This remarkable transformer stands out with its exceptional features, including ultra-low energy loss, virtually silent operation, and unmatched efficiency. It epitomizes energy conservation, significantly reducing environmental pollution and impact. Unlike traditional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. Using the ingenious elasticity of the corrugated oil tank, it autonomously regulates and compensates for oil volume changes, maintaining a perfectly sealed environment that protects the transformer from air exposure. This key feature effectively prevents oil degradation, extends insulation life, and greatly enhances operational reliability—all without necessitating routine maintenance during standard use.
