35KV series transformers are mainly used in urban and rural power grids and other industries, industrial and mining enterprises, power transmission and distribution industries, as well as agricultural projects.The transformer body adopts a high temperature resistant hybrid insulation system with optimal supporting components to achieve a design life of 30 years.

S-series: refers to transformers with a "three-dimensional wound core" or "stepped laminated core" structure, but "S" in older models often directly represented "three-phase". In the context of S11, it usually refers to a core using high-quality grain-oriented silicon steel sheets and stepped laminated technology.
