Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, a pioneering innovation by Chaotai Power, stands out with its exceptional features of low loss, minimal noise, and outstanding efficiency. These attributes collectively result in significant energy savings and a reduction in environmental impact. In contrast to conventional oil-immersed transformers, this advanced model eliminates the need for an oil conservator. Instead, it utilizes the remarkable flexibility of the corrugated oil tank's sheets to automatically adjust and compensate for variations in oil volume. This design isolates the transformer from the atmosphere, safeguarding it against oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for maintenance during regular operations.
