Application:
GN30-12 type rotary indoor high voltage isolating switch is a new type of touch rotating knife type isolating switch,the main structure in three-phase chassis of the upper and lower two plane, fixed two set of insulator and contact,byrotating contactor, so as to realize the switch of switching.
GN30-12D type switch is on the basis of GN30-12 switch increases with the form of earthing knife, can meet the
needs of different power systems.This product design is compact, small footprint, insulating ability is strong, easy
to install, the performance meet GB198589 “ac high voltage isolating switch and earth switch” requirements,
applicable to rated voltage 10 KV AC 50 HZ and the following indoor systems, as in the cases with voltage without
load,for opening and closing current.Can be used with high voltage switch cabinet,and also can be used alone.
