33kV On load power transformer

    Features of Products

    SZ11 series 33KV 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.
