High Voltage 12KV Auto 3 Phase Remote Control SF6 Gas Circuit Breaker For Mining
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.
Basic equipments:
1. Current transformer protection poles 2 pieces
2. Spring mechanism AC220V
3. Surge arrester device
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.
4. Reclosing controller and series FTU and RTU.

| Product Feature |
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. |
| Ambient condition |
1. Altitude: ≤ 2000m 2. Ambient temperature: -40°C~+40°C 3.The wind speed does not exceed 34m / s (equivalent to 700pa on the cylindrical surface) 4. Maximum Temperature Drop: no more than 25°C 5. There will be have dew under the condition of high temperature low down hastily.
