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.
