Features of Products

SZ11 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.

Standard of on load transformer:

GB1094.1-2013; GB1094.2-2013; GB1094.3-2013; GB1094.5-2008; GB/T 6451-2008;
