12kv Outdoor Vacuum Circuit Breaker with Switchgear Protction Zw8-12g
1, Product description
ZW20-12 model outdoor AC vacuum circuit breaker is used to make and break load
current, overload current and short-circuit current in 12kV, 50/60Hz power system.
It's applicable for substations, industry and mining, urban and rural electricity power
networks, especially applicable in occasions with frequent operation and automatic
power distibution network. It accords with the standards of IEC62271-100 &GB1984
AC high voltage circuit breaker, GB/T 11022 HV General technical requirement of
switches and control apparatus.
with frequent operations.
2, Optional equipments
1. Current transformer, metering pole 3 pieces 200/5 or higher.
2. Outer voltage transformer 2 pierces (for control power supply and metering).
3. Motor spring mechanism AC/DC220/1 10/48/24V.

3, Specification list:
5, Product characteristics
1. Ideal apparatus in urban and rural electricity network reform : Remote function:remote
control, remote metering, remote communication and remote adjustment.
2. Flexible operating: Both power storage and CO operation are motor and manual operated,
remote and local operation are both available.
3. Excellent breaking capability: Break short-circuit current 25kA up to 30 times.
4. Small operation power and high dependability: The small motor-driving spring operation
mechanism with new design is of lowest operation power (about 30W).
5. Multiple nstallations: Pole mounted and pad mounted.
6. Reliable sealing: The mature sealing technology assures reliable sealing performance
7. Particular incoming and outgoing method: Silicon rubber bushing to make enough insulate distance.
8. Safe operation: Anti-explosive device mounted on the top of box prevents heated gas and maters from
spattering out when inner fault occurs.
