Product Description
Oil Immersed Series Transformer:
Introducing the revolutionary S11-M series fully sealed oil-immersed power transformer, meticulously engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This extraordinary transformer stands out with its ultra-low energy loss, serene operation, and unmatched efficiency. It sets a new standard for energy conservation, dramatically reducing pollution and shrinking the environmental footprint. In contrast to conventional oil-immersed transformers, this cutting-edge model does away with the necessity of an oil conservator. Thanks to the ingeniously designed corrugated oil tank, it self-adjusts to oil volume changes, maintaining a perfectly sealed environment that shields the transformer from air exposure. This groundbreaking feature effectively prevents oil degradation, significantly prolongs the lifespan of insulation materials, and vastly enhances operational reliability—all while being maintenance-free under normal conditions.
