Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer by Chaotai Power. Engineered for excellence, it boasts remarkable features such as low loss, minimal noise, and exceptional efficiency, delivering superior energy savings and reduced pollution. Unlike conventional oil immersed transformers, this innovative design eliminates the oil conservator, utilizing the corrugated oil tank's flexible sheet to automatically adjust and compensate for oil volume changes. Completely isolated from air, it significantly reduces oil degradation and insulation aging, ensuring enhanced operational reliability and maintenance-free performance under normal conditions.
