Description
GN30-12 rotary-type indoor high-voltage isolation switch is a rotary blade-type touch a new isolating switch, the main structure is a three- phase total of chassis, the next two planes, two sets of insulators and the fixed contact, pain Touch a revolving knife, in order to achieve a sub-closing switch.
GN30-12D type switch is GN30-12-type switch based on the increase with a grounding in the form of a knife can meet the needs of different power systems. This product is compact design takes up little space, insulating ability, easy to install and adjust its performance in line with GB1985-89 <AC high-voltage isolating switches and earthing switches> requirement applicable to the exchange rated voltage 10 kV, 50Hz and below indoor system, as there is voltage at no load conditions, the Cut-off circuits. Supporting the use of High Voltage Switchgear can also be used alone.
