Structure feature
GW9-12(W) disconnect switch is single type.
- This series switch have normal and anti-pollute two difference models, it composed of frame,support insulator, with power part
and operating mechanism. - Each pole have two pieces blade, there is press spring near the contactor base and have adjusted nut to keep good contact press,
there is a support structure on the blade, it can be locked after closing, so it will not be closing b y itself u nder any condition,
under normal or short-circuit condition, it can ensure the reliable performance of dynamic and thermic stability.
