GAV Grounding Disconnect


15-550kV/40,63 or 75kA

MindCore Technologies GAV ground switches are a station class vertical break ground switch, the switch is typically used to give a visible ground point. This allows for a secure environment for workers to perform maintenance, service or any other task required on nearby equipment.


Designed to utilize the high strength and lightweight characteristics of aluminum alloys, the GAV ground switch can be mounted in a parallel or perpendicular installation. Combined with time-tested silver coated copper contacts that are highly visible and easily replaceable, the current carrying path is exempt of any rotating points ensuring maximum conductivity over time.




The GAV ground switch applications are used in substations with high short-circuit requirements, since it’s rated up to 75 kA rms (3s). Full copper version available up to 245kV.


Stand alone or combined with a vertical, center or double break switch are all available. Additional key component possibilities such as painted blade for extra visual confirmation or key interlock hardware provision or mechanical interlock hardware provision or electrical interlock allow flexibility to comply with any project requirements.
