Wind transformer substation step up Oil immersed Type Transformer
Summarize
ZGS-Z.F-/11 series wind power combined transformer is a special power equipment integrating step-up transformer, HV current limited fuse, load switch, LV switch and related auxiliary equipments. It transforms the 0.69kV voltage produced by wind power motor into 35kV,and output the electricity through 35KV cable circuit, which is the ideal equipment in wind power complete set equipment.
