Product Description
Oil Immersed Series Transformer:
The S11-M series, a fully sealed oil-immersed power transformer, meticulously crafted by Chaotai Power, is designed to exceed expectations with its unparalleled benefits. Revel in its low loss and low noise attributes, paired with its outstanding efficiency, promising significant energy savings and reduced pollution footprints. Unlike traditional oil-immersed transformers, this innovative model eliminates the need for an oil conservator. The adaptable corrugated sheet of the oil tank dynamically adjusts and compensates changes in oil volume, ensuring a seamless operation. Ingeniously isolated from air exposure, it minimizes oil deterioration and insulation aging, bolstering operational reliability and practically eliminating the need for maintenance during normal operations.
