AC electrical combined distribution substation with three phases oil immersed transformer
AC electrical combined distribution substation with three phases oil immersed transformer
1.Rated voltage:6/0.4;10/0.4KV
2.Rated capacity:200~1250/50~400kVA
Descriptions and applications:
ZBW series AC Combined substation is a compact complete power distribution equipment comprised of the high voltage distribution equipment,transformer,low voltage electric equipment and energy metering device and other distribution facilities which are pre-assembled in a cubicle.
As a device for accepting and distributing electricity in the electric distribution system,it's used in urban high-rise buildings,urban and rural constructions,residential quarters,small and medium-sized plants,mines,oil fields,temporary construction electricity utilization and other places.
