The patented PhaseRaiser® system is the most innovative and economical way to increase conductor clearance on energized lines. A qualified line crew of 5 can raise an average of 3-5 structures per day without taking the line out of service, saving significant amounts of money versus structure changeouts. H-frame structures can be raised an additional 5, 10, 15 or 20 feet for about one-third the cost of a changeout. Since 1997, more than 12,000 energized structures have been safely raised using the PhaseRaiser® system. A specialized equipment trailer is required and can be purchased or rented from LWS.
