High Pressure Rotary Isolating Switch GN30-12
1.GN30-12 series indoor rotary high voltage isolating switch is a new type of rotary contact knife type isolating switch.
2.The main structure is on a three-phase common chassis and two lower planes. Two sets of insulators and contacts are fixed. Touch the knife to open and close the switch.
3.This product is compact in design, takes up little space, has strong insulation, and is easy to install and adjust.
4.For indoor power systems with a rated voltage of 12kV AC 50Hz and below, for opening and closing circuits under voltage and no-load conditions.
5.It can be used together with high-voltage switchgear or alone.
12kV High Voltage Vacuum Contactor
1.This series of vacuum contactors are made of high-quality vacuum switch tube, metal frame and insulation bracket.
