ZBW20(JBW)-12 Series Fully-sealed Impact Prefabricated Substation
 

General
 ZBW20(JBW)-12 Series Fully-sealed Impact Prefabricated Substation is a kind of integrated complete power transmission and distribution equipment,used in 10kV.AC 50 Hz power transmission and distribution system with a transformer rated capacity of 50-1600kVA.It is widely used in outdoor power supply fields,such as residential zone ,factory and mining,hospital,hotel,part,oil field,airport,wharf,railway,shopping store,and other temporary,etc.
 This product can be used not only in a close-ring-net for power distribution,but also in transformation power net for terminal power supply.
 Features:With a combination advantages of American-type prefabricated substation and European-type prefabricated substation.Its HV part and transformer could be divided.
 High voltage side is equipped with HXGN26 SF6 type RMU switchgear.It could prevent missing phase operation.so it will lift up opration reliability.It also owns advantages of less maintenance,a complete protection capacities capacities against error opration and its overload capacity could reach up to 120%.
 Varied materials could be chose as enclosure materials,such as aluminum alloy plate,steel plate,compound plate,etc.Its shape will be beautiful with varied types and sizes.
