Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, meticulously crafted by Chaotai Power, stands out with its remarkable features of low loss, minimal noise, and exceptional efficiency. This innovative design ensures significant energy savings and minimizes environmental impact. Unlike conventional transformers, our fully sealed model eliminates the oil conservator. The oil volume adjustments are seamlessly managed by the corrugated oil tank's flexible sheet, ensuring the transformer remains air-isolated. This design ingeniously prevents oil degradation and insulation aging, enhances operational reliability, and significantly reduces the need for maintenance in standard operating conditions.
