Haverfield Aviation, founded in 1981, pioneered and patented the use of the helicopter as a transmission- distribution system work tool introducing highly productive live-line maintenance and comprehensive close up inspection to the electric power industry. Today, over 80 electric utilities worldwide are regular repeat customers and that number continues to grow significantly each year. Haverfield’s airborne services span the full scope of maintenance tasks that were previously provided only by conventional methodologies. Haverfield’smethods have vastly improved the speed and efficiency of these tasks and added the important dimension of conducting most work while the lines remain fully energized. Our company regularly conducts energized maintenance on lines ranging from 39kV to 765kV.
