Product Description
Oil Immersed Series Transformer:
Introducing the S11-M Series Fully Sealed Oil Immersed Power Transformer, a visionary creation by Chaotai Power, renowned for its outstanding low loss, minimal noise, and remarkable efficiency. This transformer is engineered to deliver exceptional energy-saving results while significantly reducing pollution. Unlike conventional oil-immersed transformers, our fully sealed marvel does away with the traditional oil conservator. Instead, it boasts an innovative design where the oil volume fluctuations are smoothly regulated by the flexible corrugated sheet of the corrugated oil tank. This intelligent isolation from air effectively slows down oil deterioration and prevents insulation aging, thus enhancing operational reliability and eliminating the need for maintenance during normal operation.
