Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a revolutionary fully sealed oil immersed power transformer by Chaotai Power. This transformer excels in delivering superior energy efficiency with its low-loss and low-noise capabilities, leading to significant energy conservation and reduced environmental impact. Unlike conventional models, this innovative design eliminates the need for an oil conservator by utilizing the corrugated oil tank's sheet elasticity to automatically manage oil volume changes. This isolation from air not only decelerates oil deterioration and insulation aging but also bolsters operational reliability, ensuring maintenance-free functioning during normal operations.
