Power network primed for summer
The pre-summer maintenance activities also include inspecting transmission lines ahead of the busy storm and cyclone seasons.
“Powerlink has an important responsibility to deliver a safe and reliable supply of electricity to five million Queenslanders and this activity helps ensure our transmission network is ready for Queensland’s unpredictable weather over summer,” executive general manager operations and service delivery Gary Edwards said
“Washing is carried out on towers to remove any contaminants, including dust, which can build up on the insulators during the drier parts of the year.
“Highly-trained pilots fly the helicopters, which are fitted with a special attachment that sprays demineralised water at high pressure to clean the insulators.
“Local residents may see the helicopter moving relatively quickly and at a low level along the transmission lines with a pause to wash the insulators.
“The pilots will endeavour to maintain the maximum distance practically possible from houses, livestock and crops, and be as quick and non-disruptive as possible to minimise any potential disturbance to our communities.”
Insulator washing will be undertaken in areas including Alice River, Arriga, Black River, Clare, Greenvale, Hervey Range (Charters Towers), Innot Hot Springs, Kelso, Koah, Mareeba, Millaroo, Pinnacles, Toomulla, Trebonne, Walkamin and Woodstock (weather permitting).
