Helicopter inspections help prepare transmission lines for summer

A low-flying helicopter has been used to carry out routine maintenance inspections of Powerlink Queensland’s high-voltage transmission lines.

Powerlink chief executive Merryn York said the aerial inspections were undertaken as part of Powerlink’s annual summer readiness activities to ensure the safety and reliability of the transmission network during storm and cyclone season.

“Highly-trained pilots fly the helicopters, which are fitted with long booms that spray demineralised water at high pressure to clean the insulators,” she said.

Ms York said preparations for the upcoming summer were ongoing and included activities such as resource planning, emergency exercises, vegetation management, and inspections and maintenance of transmission lines and substations.
