 GN30-12 (D) series of spiral indoor high voltage isolation switch - the silicone rubber wall bushing [product information] 
 First, an overview 
 N30,-12 rotary indoor high voltage disconnect switch is a rotating touch knife-like new isolation switch, the main structure is a three-phase total of the bottom rack, and under two plane fixed two sets of crepe edge of the child and contact of opening and closing of the switch by rotating touch the knife to achieve. 
 GN30-12D switch increase in the GN30-12 switch based on the form with ground knife, to meet the needs of the different power systems, small insulating ability of the product design elite back space. Ease of installation and adjustment, and its performance in line with the requirements of GB1985-89 "AC high-voltage isolating switches and earthing switches", rated voltage 12 kV AC 50Hz and below indoor power system, as in the no-load voltage, the division circuits. With supporting High Voltage Switchgear, can also be used alone.
