Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer by Chaotai Power. This engineering marvel is designed to deliver exceptional performance with low loss, minimal noise, and superior efficiency, setting a new benchmark in energy savings and pollution reduction. Unlike conventional oil-immersed transformers, this innovative model eliminates the need for an oil conservator. The transformer ingeniously adjusts the oil volume via the elasticity of its corrugated oil tank, maintaining a perfect seal against air ingress. This feature significantly decelerates oil deterioration and insulation aging, ensuring enhanced operational reliability and virtually eliminating maintenance during regular operations.
