Spacer Installation on 765,000 volt line
Matt Brink
Helmet-camera footage of linemen installing a spacer on an energized 765,000 volt transmission line, working from a helicopter. The crew bonds on and off the live wire as part of the job.
Cited as a striking example of live-line work and of potential equalization, with the air as the insulator.
