Achievement

Upgrade of the existing electrical infrastructure between Lindfield and Ku-ring-gai to meet current and future demands.

Summary

Ausgrid determined that the three 33kV feeders between Ku-ring-gai Subtransmission station, Gordon RailCorp substation and Lindfield zone substation required replacement due to the ageing of the existing infrastructure and to allow for additional capacity during upgrades in other parts of the network. MMA Civil contractors are in the process of installing the 33,000 volt underground cables for the 4.1km between Ku-ring-gai STS, Gordon RailCorp substation and Lindfield zone substation so as to achieve the required cable rating. This project includes the following activities

  • Laying 4 x 200mm diameter conduits 4.1km in length between Linfield & Ku-ring-gai Substation
  • Laying 2 x 63mm diameter conduits 4.1km length between Linfield & Ku-ring-gai Substation
  • Installation of 3 off XLPE cables
  • Installation of fibre optic cable between the three substations for communications
  • Constructing of underground joint bays
  • Installing and joining cables
  • Resurfacing of roads
