Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series, a state-of-the-art fully sealed oil immersed power transformer by Zhejiang Chaotai Complete Equipment Co., Ltd. Engineered to perfection, this transformer boasts remarkable attributes such as minimal energy loss, whisper-quiet operation, and unparalleled efficiency. Its design not only ensures significant energy conservation but also actively reduces environmental pollution. Unlike traditional oil-immersed transformers, this innovative model eliminates the need for an oil conservator. It cleverly utilizes the elasticity of the corrugated oil tank's corrugated sheet to automatically adjust and compensate for changes in oil volume. By being completely isolated from air exposure, it significantly slows down oil degradation and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during regular use.

Zhejiang Chaotai's cutting-edge fully sealed oil-immersed power transformers are engineered for low loss, quiet operation, and high efficiency, ensuring remarkable energy savings and pollution reduction.
These advanced transformers, unlike conventional ones, dispense with the oil conservator and ingeniously adjust oil volume changes using a corrugated oil tank. This isolation from air effectively reduces oil deterioration and insulation aging, boosting operational reliability and negating maintenance in standard operations.
