Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, meticulously crafted by Chaotai Power, offers remarkable benefits such as minimized loss, whisper-quiet operation, and outstanding efficiency. These features contribute significantly to energy conservation and pollution reduction. Unlike conventional oil-immersed transformers, this innovative design eliminates the need for an oil conservator. The oil volume adjustments are expertly managed by the flexible corrugated sheet of the oil tank, ensuring automatic compensation. This transformer is air-sealed, effectively preventing oil deterioration and insulation aging, while simultaneously boosting operational reliability. This means maintenance-free operation under normal conditions.
