10kV electric power transformers
1. S11 series transformer is a new generation energy saving product

 1  Model and its meaning

 

S11 series transformer idle loss reduces 20-30% than S9 series transformer, the idle current reduces 70-80% than S9 series transformer. The energy saving effect is obvious and is the initial selective product of electric departments.
