The helicopter operates at roughly the same height as the power poles, ensuring effective cleaning and silicone application.
We’re committed to improving network resilience for our communities. Helicopter maintenance work, especially the washing and siliconing of insulators, helps reduce the risk of pole top fires and ensures consistent and safe power supply across Western Australia.
The maintenance involves two steps. First, we spray insulators and powerlines with demineralised water. In the second phase we return to apply a protective silicone layer.
We start by using demineralised water for initial cleaning. Following that, 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.
Helicopters won’t be flying in and around residential streets, main roads, close to houses, livestock, etc. Other type of treatments can be employed to maintain the network where a helicopter cannot fly.
