Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series, a groundbreaking fully sealed oil-immersed power transformer, expertly engineered by Zhejiang Chaotai Complete Equipment Co., Ltd. This extraordinary transformer is distinguished by its impressive features: ultra-low energy loss, whisper-quiet operation, and outstanding efficiency. It serves as an exemplary model in energy conservation, dramatically reducing pollution and minimizing environmental impact. Diverging from traditional oil-immersed transformers, this innovative model forgoes the oil conservator. The smart design autonomously regulates oil volume changes using the elasticity of a corrugated oil tank, maintaining a perfect seal against air exposure. This cutting-edge feature prevents oil deterioration, slows the aging of insulation, and significantly enhances reliability, all while eliminating the need for maintenance during typical operations.
