Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a truly state-of-the-art fully sealed oil-immersed power transformer, meticulously engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This outstanding transformer distinguishes itself with its remarkable features: it ensures minimal energy loss, produces very little operational noise, and delivers unparalleled efficiency. As a quintessential energy-saving marvel, it dramatically diminishes pollution and environmental impacts. Unlike traditional oil-immersed transformers, this sophisticated model requires no oil conservator. Thanks to its intelligent design, it autonomously manages and adapts to oil volume variations through the flexibility of the corrugated oil tank, effectively isolating the transformer from air exposure. Such cutting-edge innovation prevents oil degradation, significantly slows insulation aging, and remarkably bolsters operational reliability—while entirely eliminating the necessity for maintenance during regular operations.

The fully sealed oil-immersed power transformer, a hallmark of innovation by Chaotai Power, features extremely low energy loss, quiet operation, and extraordinary efficiency. It stands as an exceptional energy-saving solution, significantly reducing pollution and environmental impact.
In stark contrast to conventional oil-immersed transformers, this cutting-edge fully sealed design does away with the need for an oil conservator. It effortlessly manages oil volume fluctuations through the elasticity of the corrugated oil tank sheet, effectively keeping the transformer isolated from air. This pivotal feature not only prevents oil deterioration and insulation aging but also drastically enhances reliability and completely eliminates the requirement for regular maintenance.
