Product Description
Oil Immersed Series Transformer:
The S11-M series, a fully sealed oil-immersed power transformer, is a masterpiece from Chaotai Power. Engineered with precision, it boasts low loss, minimal noise, and exceptional efficiency, promising significant energy savings and reduced pollution. Unlike conventional oil-immersed transformers, this advanced model eliminates the oil conservator. The ingenious design uses a corrugated oil tank, automatically adjusting oil volume through its flexible corrugated sheets. This innovative approach isolates the transformer from air, significantly slowing oil degradation and insulation aging, thereby enhancing operational reliability and negating the need for maintenance during normal operation.
