Model
Structure feature
- Adopt roll bearing to keep flexible driving.
- Adopt umbrella-gear wheel mechanism to ensure O/C operating congruously.
- There is an direction-limited device to ensure the contactor under good direction, at the same time, the handcr aft
was fastened after operating to ensure the security performance. - Contact distance is large enough.
- There are three type earth method, without earth, single earth, double earth.

Structure feature
There are two supporting insulators fixuped on the pedestals respectively with the 50℃ inclinat ion, and the main components
include pedestals, supporting insulators, connection seat, contacts earthing blades, earthing fixed contact and so on. There are
three kinds of disconnect switch: without earthing, single-earthing and double-earthing. It be provided with mechanism linkage
between principal axis and earthing blades and assistant switch, operating can be achieved by manual and motor.
