400kV Live Line Insulator Wash. This is an operational rather than a training shot, but its one of the tasks carried out during Aeropowers live line re-certification training. Insulator washing is performed to remove salt and other pollution deposits from insulator strings which allows them to operate at a greater efficiency. This can be carried out with the line still energised by using “clean” water. Essentially, pure water is not a conductor of electricity.
