Features of Products
SZ10 series 11kV class On-load voltage regulation is a voltage regulation method by which a transformer can change the voltage
by changing the tap gear when operating under load. Power electronic component switches have the advantages of frequent switching, no spark and long service life,
so they can be used as on-load tap-changer for distribution transformers.
