Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a fully sealed oil-immersed power transformer masterfully created by Zhejiang Chaotai Complete Equipment Co., Ltd. This exceptional transformer is recognized for its outstanding characteristics: low energy loss, ultra-quiet operation, and unparalleled efficiency. It epitomizes a premier energy conservation solution, significantly reducing environmental impact and pollution. Unlike conventional models, this cutting-edge transformer does away with the oil conservator. Its intelligent design autonomously compensates for oil volume variations using the corrugated oil tank's elasticity, effectively sealing the transformer from air exposure. This ingenious feature prevents oil degradation, slows the aging of insulation, and significantly boosts operational reliability, all while eliminating the necessity for maintenance during regular operations.
