More than $9m of maintenance work is being carried out to shore up performance of the electricity grid in north Queensland.
It involves replacing 100 kilometres of earth wire from Townsville to Chalumbin Substation near Tully and refitting 18 transmission towers on the line to Kareeya Substation.
Earth wires have a dual role of protecting transmission lines from lightning strikes and providing a communication path to allow remote operation and monitoring of Powerlink’s network.
The state government says it will maintain network performance and ensure the safe, reliable and cost effective supply of high voltage electricity.
The work is expected to extend the technical life of the line for 15 years.The lines were built in the late 1980s.
