Main Tasks

Installation of 330kV cables 28.5km (Picnic Point to Haymarket).

Summary

To date the Metro-grid or ‘Cable 42 project’ is the largest and most complex Diona has delivered. Metrogrid was a critical part of an upgrade to the existing Sydney electricity network to provide for future electricity needs.

 

The project consisted of approx. twenty-four kilometress of 3 x 330kV cables constructed generally through residential areas via direct laid cable trenches. The cable route started at Picnic Point (Southern Sydney) and finished at Sydney Park, Alexandria. A tunnel was constructed by others from Sydney Park to Haymarket (Sydney CBD) in which the remaining four kilometres of cable was installed.

 

Diona were responsible for the design of cable trench alignment and various specialist methods to cross creeks, arterial roads and railway lines. The trenched component of the project was divided into thirty-six sections ranging from 480 metres to 800 metres long (limited by the length of cable practical to be transport on a cable drum and cable installation constraints).
