4, Structure:
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.
