Product Description
Oil Immersed Series Transformer:
Presenting the S11-M series, a fully sealed, oil-immersed power transformer crafted by Chaotai Power. This exceptional product is designed to deliver superior performance with low loss, minimized noise, and remarkable efficiency, culminating in significant energy savings and reduced environmental impact. Unlike traditional oil-immersed transformers, this innovative model eliminates the oil conservator, with oil volume changes seamlessly adjusted and balanced by the corrugated oil tank's flexible design. By isolating the transformer from the ambient air, it effectively mitigates oil degradation and insulation aging, thus enhancing reliability and ensuring maintenance-free operation under normal conditions.
