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
