Product Description

ZVMD Vacuum on load tap changer

General
ZVMD on load tap changer is combined type vacuum innovative product.It's a high quality,high technology
product design basic of manufacturing technology and experience of tap changer during half a century.
ZVMD combined type vacuum innovative on load tap changer applies to the power transformer or industrial
transformer with max.working voltage 72.5kV,126kV,170kV,252kV,max.rated through 3phase 400A,500A,
600A,1000A,single phase 400A,500A,600A,800A,1200A,1500A,rated frequency 50Hz or 60Hz to make voltage
regulating under load.It applies to 3phase Y connection neutral point voltage regulation,single phase any regulating.
This tap changer use integral type glass fiber reinforced expoxy extensively insulation tube so that its mechanical 
strength is higher,non-deformability is stronger,insulation performance is better,and more beautiful appearance.
