Product Description
Oil immersed series transformer:
Introducing the remarkable S11-M series fully sealed oil-immersed power transformer, crafted with precision by Chaotai Power. This innovative transformer boasts exceptional features such as low loss, minimal noise, and superior efficiency, delivering impressive energy-saving benefits and reducing environmental impact. Unlike conventional oil-immersed transformers, our advanced fully sealed design eliminates the need for an oil conservator. The dynamic oil volume is seamlessly adjusted and compensated using the corrugated sheet's elasticity within the corrugated oil tank. This design isolates the transformer from air exposure, significantly slowing oil degradation and insulation aging. As a result, it enhances operational reliability and ensures maintenance-free performance during normal operation.
