Ever wonder how transmission lines are repaired? Introducing high flying linemen

Email   PrintPrint

The U.S. electricity grid includes more than 200,000 miles of high voltage (230 kilovolts and higher) power lines. This network of wires helps to maintain a reliable supply of electricity across the country. For those who wonder how these lines are inspected and repaired, check out this video of some high flying linemen – courtesy of the International Brotherhood of Electrical Workers Local 94 in New Jersey.

    We use helicopters every now and then. It is good for difficult access areas and lifting heavy components.
