Product Description
Oil Immersed Series Transformer:
Introducing the groundbreaking S11-M series fully sealed oil-immersed power transformer, crafted with precision and innovation by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional transformer is a testament to technological advancement, boasting extraordinary attributes such as ultra-low energy loss, nearly silent operation, and unparalleled efficiency. It stands as a beacon of energy efficiency, dramatically cutting down on environmental pollution and minimizing ecological impact. Unlike conventional oil-immersed transformers, this state-of-the-art model operates without the need for an oil conservator. Through the remarkable elasticity of its corrugated oil tank, it autonomously adjusts and stabilizes oil volume variations, ensuring a perfectly sealed system that protects the transformer from air contact. This revolutionary feature not only halts oil degradation but also significantly extends insulation longevity and enhances operational reliability—all while eliminating the need for routine maintenance under normal operating conditions.
