American type Rated voltage:10KV Rated frequency:50 or 60 HZ
ZBW series high-voltage/low voltage prefabricated substation(American type) is equipped transformer and load switch and HV fuse in the transformer room.The insulating liquid of transformer is used as insulating media and heat radiating media to the whole product.This kind of substation has the advantages of smaller volume and weight,less maintenance,higher security.
This product can be used not only in a close-ring-net for power substation,but also in transformation power net for terminal power supply.The product is used in 10KV ,50 or 60HZ power distribution system with a transformer rated capacity of 50-16000KVA.It is widely used in outdoor power supply fields such as city,residential zone,factory and mining,hotel,hospital,park,airport,wharf,railway and other temporary facilities,etc.
