Overview
- PNC-GGS Series of Pad-mounted Multiple-circuits (2-way 1-switch to 7-way 7-switch) Load Break Switches are forunderground distribution lines up to 25.8kV installed on the ground and used for branching lines.
- This SF6 Gas insulated switch can corporate with the Distribution Automation System through FTU-GD100, and also isolate afaulted section of distribution line from the control center.
- PNC-GGS Series can be manually operated or motorized for fault isolation, remote control and automation to suit your powerline requirements.
- PNC-GGS Series has been fully certified in accordance with IEC60694, IEC60265 to meet and exceed customer'srequirement.
