12kv Power Transmission Supply & Prefabricated Compact
ZBW1 series combined substation is designed by our company for
satisfying the need of city net construction, it features of
compact structure, strong whole set,safe and reliable operation,
convenient maintenance, beautiful appearance. It is widely used in
out-door power supply fields such as high buildings, residential
zone, factory and mining, hotel, park, oil field, airport, wharf,
railway, shopping store, and other temporary facilities, etc. This
product can be used not only in a closing-net for power
distribution, but also in transformation power net for terminal
power supply. The product firstly passes the appraisal from
Mechano-electrical Department and Energy Department in our country
in 1991, the performance reach to the national advanced level.
