Product Description



Oil Immersed Series Transformer:
Meet the revolutionary S11-M series, a fully sealed oil-immersed power transformer, meticulously engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional transformer sets a new standard with its ultra-low energy loss, hushed operation, and unmatched efficiency. It embodies the essence of energy conservation, dramatically reducing pollution and lessening environmental footprints. Unlike conventional oil-immersed transformers, this cutting-edge design omits the need for an oil conservator. Its ingeniously crafted corrugated oil tank self-regulates and compensates for oil volume fluctuations, ensuring a perfectly sealed environment that shields the transformer from air intrusion. This groundbreaking feature effectively prevents oil degradation, significantly prolongs the lifespan of insulation materials, and greatly enhances operational reliability—all the while eliminating the need for routine maintenance under normal conditions.
