Helicopter activities

Stringing transmission lines

We use helicopters to string transmission lines during our construction projects. If you live in an area where we have a project, you can keep up-to-date with the project in our Project section.

Maintenance patrols

Sometimes we need to undertake maintenance inspections and work on our lines using low flying helicopters.

See the table below for upcoming patrols.

*weather permitting

Cleaning insulators

As part of our maintenance patrols, we sometimes clean the insulators on transmission towers by using helicopters. This is done with high-pressure water, which is safe and effective.
