GN30-12 INDOOR ROTARY HIGH VOLTAGE DISCONNECTING SWITCH

Short Description:

GN30-12 indoor rotary high voltage disconnecting switch is a new type of rotary contact knife disconnecting switch. The main structure is to fix two sets of insulators and contacts on the upper and lower planes of the three-phase common chassi.Rotate the contact knife to realize the opening and closing of the switch.GN30-12D indoor rotary high-voltage disconnecting switch is based on the GN30-12 indoor rotary high-voltage disconnecting switch, adding a form with a knife to meet the needs of different power systems. This product is compact in design, small in space, strong in insulation, and easy to install and adjust. Its performance meets the requirements of GB1985-89 “AC High-Voltage Disconnecting Switch and Grounding Switch. It is suitable for indoor systems with a rated voltage of 10 kV and AC below 50 Hz. It is used as a switching circuit when there is voltage and no lo ad. It can be used in conjunction with high-voltag e switchgear or alone.
