thats the point of being in a chopper...ya don't get shocked...its the same as if a person tangles with a high line while in a parachute. its a safe job...its the fall that ya should worry about....
someone asked what they were doing?...they have infrared cameras that look for hot spots on the lines...potential weak or faulty spots...they then go out and repair them by spicing them. or to do insulator cleaning. where they make sure that the ceramic insulators are clean and in good shape. looks like a total blast...where do i sign up....
