33KV Floorstanding Prefabricated Compact Transformer , Combined
ZBW3-40.5 series Packaged substation is a kind of integrated
complete power transmission and distribution equipiment, used in
24kV, AC 50Hz power tranmission and distribution system with a
transfromer of rated capacity of 30-2500kVA. It is widely used in
out-door power supply fields such as high buildings, residentail
zone, factory and mining , hotel, park, oil field, airport, wharf,
railway, shopping store and other temporary facilities. This
product can be used not only in a ring net fro power distribution
but also can serve as terminal power supply for power transmiission
ZBW3-40.5 series package substation consists of three parts:
transformer room, high voltage room and low voltage room.
1. High voltage sides is equipped with HXGN series RMU (aerogenesis
type, compressed air type, vacuum type or SF6 type), equipped with
LBS, fuse inside (CB could be equipped, if required).
2. LV side adopts new type ACB, with high breaking capacity and
good protection capacity.
3. Transformer room adopts oil immersed type or dry type
4. Caries materials can be used as enclosure materials, such as
aluminum alloy plate, steel pate, compound plate, etc. Roof is
double layered, protecting against heat radiation.
5. Inside, there are cooling equipment and anti-comdensation
