Product overview
GN30-12 indoor rotary high-voltage isolating switch is a new type of rotary contact knife isolating switch. Its main structure is to fix two sets of insulators and contacts on the upper and lower planes of a three-phase common chassis. knife, thereby realizing the opening and closing of the switch.
The GN30-12D switch is based on the JLGN30-12 switch and adds a grounding blade, which can meet the needs of different power systems. This product has a compact design, small space occupation, strong insulation capability, and is easy to install and adjust. Its performance complies with the requirements of GB1985-89 "AC High Voltage Isolating Switch and Grounding Switch" and is suitable for indoor systems with a rated voltage of 10 kV AC 50Hz and below. , used as a switching circuit when there is voltage but no load. Can be used with high-voltage switch cabinet or alone
