Earthing Switches - G60
72,5 - 550kV
The G60 earthing switch can be used stand-alone, e.g. as bus bar earthing (145 kV or higher), or mounted on disconnectors. Due to its modularity it can be mounted on most disconnectors from EB Elektro and other manufacturers.
The earthing switch has a knee-joint design with tulip contact.
The G60 is tested according to IEC standards. It can be hand or motor operated, and can also be remotely operated.
