This disconnect switch consists of frame, operating insulator, static contact, blade, linkage spring mechanism, etc. Frame: 5mm thickness bended armor ptate, there are holes on the frame to fixed post insulator. Post and operating insulator: adopt ZS 12,24,40.5 series outdoor clubbed post insulator. The mini resist bend load is 4000N. Static contactor: it is made of violet copperplate and fixed on post insulator. Blade: it is made of rectangular violet copperplate, there is a press-spring to adjust press. The switch can be vertically or horizontally installed in outdoor with CS□ mechanism.
