With a network area of 255,000km2, that’s a lot of ground to cover. One way to improve the efficiency of our work is to use a helicopter to conduct patrols/inspections, washing, siliconing, and routine maintenance of transmission and distribution lines and assets. It also means that we don’t need to drive on to your property to do all of this.
Pollution and humidity can build up on electrical insulators and so we need to keep them clean to minimise reliability issues. Live line washing means that the power stays on while we do it. The helicopters fly low – around the same height as poles – so we recommend that farmers who may be concerned about disruption to their livestock consider moving them away from power lines.
