Holroyd to Potts Hill 330kV Joint Bays

Project Details

Client : Dinoa Civil Engineering on behalf of Transgrid
Type : 330kV Joint Bay Earth Grid x 84 Joint Bays
Date : 2013 to 2014
Scope of project:

Supply and installation of complete earth grid installation including 300mm2 bare cable buried earth grid, 4 x 3m deep earth electrodes, “Cadweld” connections, installation of purpose-built earth bars including connections and testing.

The project was carried out for Diona Civil Engineering on behalf of Transgrid along with close coordination with J Power (Japan) who were engaged to carry out the 330 kV jointing.

The project required close coordination with the client as the installation of the earth grids were installed immediately after the pre-cast joint bays were installed. Due to the amount of installations that were performed (88 in total), close management and coordination was a must.

The project was successfully completed in late 2014 on budget and on time.
