Maintaining a safe and reliable electricity supply in Central Queensland means getting right down to the nuts and bolts when it comes to inspecting transmission towers.
Powerlink recently completed the $3.4 million replacement of steel bolts and insulators across its 290-kilometre stretch of transmission line between Broadsound, Nebo and Bouldercombe substations, after inspections identified some corrosion had occurred.
Powerlink Chief Executive Merryn York said regular inspections along this key stretch of network in Central Queensland ensured the safe, reliable and cost effective delivery of electricity into the future.

“The program of works supported up to eight full-time jobs and was conducted over a number of months to minimise impact on the network and customers,” Ms York said.
“Replacing ageing insulators and steel bolts ensures the longevity of our infrastructure at the lowest long-run cost to our customers.
“Corrosion can compromise the integrity of insulators and steel bolts on the transmission towers, which is why inspections are regularly conducted and replacement works promptly completed.

“This transmission line plays a critical role in Powerlink’s network in Central Queensland, supporting industrial and economic growth in the region.
“This work demonstrates Powerlink’s commitment to effectively maintaining the transmission network, which provides electricity to four million Queenslanders.”
