The Ross to Chalumbin transmission line is a central link in Powerlink's inland transmission network, supplying high voltage electricity to North and Far North Queensland.
After operating in a tropical environment for more than 30 years, some of the line's earthwire corroded and needed replacement to ensure safe, reliable and cost effective high voltage electricity supply is maintained into the future.
The project involved replacing earthwire progressively along the line in 2016. Located at the very top of transmission towers, earthwires shield the line from lightning strikes and act as a communication path to remotely monitor the network.

Helicopters were used to string the new earthwire to minimise the impact on nearby properties and ground-level vegetation. Some towers also required on-ground access to facilitate the works.
The project was also delivered in accordance with rigorous environmental management requirements, which outlined how potential environmental and social impacts were minimised and managed.
All project activities were undertaken in accordance with property entry conditions and Powerlink's Land Access Protocol (LAP). This document outlines the standards and commitments Powerlink and our representatives adhere to when accessing properties to carry out our activities.
We were committed to safely managing potential impacts associated with the project. All activities were undertaken in accordance with rigorous environmental management requirements, which outlined how potential environmental and social impacts were minimised and managed.
The Ross to Chalumbin Earthwire Replacement Project was completed in October 2016. We thank landholders and stakeholders for their understanding and cooperation while this important project was delivered.
