Sydney Transmission Substation 33kV Feeder Upgrade Completed Two Months Ahead of Schedule

Posted 9 December 2013

Electrical Feeder UpgradeDue to the ever-growing electricity demands of South Western Sydney, the local supply authority initiated the installation of a new transmission substation to service the region. As part of the new substation installation it was identified that in order to distribute the increased network capacity to customers, the installation of seven new 33kV feeders was required..

UEA Electrical was appointed to the contract and carried out all facets of the electrical work in this complicated project, including:

  • 7 x sets of 33kV Pfisterer GIS terminations
  • 17 x sets of 33kV Tyco straight through joints (STJ)
  • Installation and termination of associated 33kV cross bonding systems
  • 28 x Installations and terminations of earth link boxes
  • 3 x new concrete pole installations (21.4/32C), along with augmentation of the 33kV overhead network
  • 3 x 33kV underground to overhead terminations (UGOH)
  • 4 x 33kV Pfisterer outdoor sealing end terminations

Due to the local electricity network’s configuration complexity, an intricate staging of all seven feeders was required. With little room for error, it was essential to anticipate any delays in program cascades which could affect the entire commissioning program.

All program targets were met and despite the potential challenges, the construction and commissioning program was completed ahead of schedule, due to the professionalism and experience of the UEA Electrical project team.

Tenacious planning resulted in exceptional delivery with outstanding safety results, indicating the significance of the UEA Electrical project management team’s paramount focus on safety.
