Helicopter line maintenance
The helicopter operates at roughly the same height as the power poles, ensuring effective silicone application.
We’re committed to improving network resilience for our communities. Helicopter maintenance work, especially insulator treatment, helps reduce the risk of pole top fires and ensures consistent and safe power supply across Western Australia.
We spray a protective layer of silicone onto insulators to reduce dust and pollution build up and reduce the risk of pole top fires.
We apply FCSIL6, a silicone product, to protect against potential electrical hazards. FCSIL6 is not classified as hazardous (based on the Global Harmonised System of Classification and Labelling of Chemicals).
It's unlikely the helicopter will need to land on private properties. However, if such a situation arises, we'll do our best to communicate with landowners in advance.
Please check our monthly list of suburbs. Our daily schedule is subject to change depending on weather and other operational considerations.
While undertaking maintenance activities on our network, our helicopters fly in accordance with aviation requirements and take into consideration things like residential streets and houses, main roads and livestock. Areas where helicopters cannot fly, we employ elevated work platform based silicone application to mitigate pole top fire risk.
