Product Description
Oil Immersed Series Transformer: Setting a New Benchmark in Transformer Technology!
Introducing the S11-M series: a fully sealed, oil-immersed power transformer from Chaotai Power, designed to deliver unmatched efficiency. Revel in the benefits of low loss, minimal noise, and superior efficiency, all contributing to a remarkable energy-saving performance while also reducing environmental impact. Unlike traditional oil-immersed transformers, our fully sealed marvel eliminates the need for an oil conservator. The innovative design allows automatic adjustment and compensation of oil volume through the corrugated sheet's elasticity in the oil tank, ensuring the transformer remains isolated from air. This isolation is pivotal in preventing oil deterioration and insulation aging, enhancing operational reliability and eliminating the need for maintenance during standard operation.
