GN30-12(D)/630A, 1250A Rotary Indoor High Voltage Disconnecting Switch | 12kV Indoor High Voltage Switchgear

Overview

GN30-12 rotary indoor high voltage disconnecting switch is a new type of rotary blade disconnecting switch. Its main structure consists of two sets of insulators and contacts fixed on the upper and lower planes of a three-phase common base, achieving opening and closing through rotary blade movement. GN30-12D switch is based on GN30-12 with additional earthing blade, meeting the needs of different power systems. This product features compact design, small space occupation, strong insulation capability, easy installation and adjustment, and its performance complies with GB1985-89 "AC High Voltage Disconnecting Switches and Earthing Switches". It is suitable for rated voltage 10kV AC 50Hz and below indoor systems for making and breaking circuits under voltage and no-load conditions. Can be used with high voltage switchgear or independently. GN30-12(D)/630A-1250A Rotary Indoor High Voltage Disconnecting Switch achieves switching between connected, isolated and earthed three positions through contact rotation, saving cabinet space, suitable for 12kV fixed-type switchgear.
