Lifting structures to increase groundline clearances

Deregulation within the electric utility industry is forcing many companies to stretch the capacities of their mature transmission lines. No longer are companies in control of new generation locations or capacities. Their mission has changed from supplying electricity to regional customer to that of the movement of power over their grid. Once the RTOs (regional transmission operators) are in place, there will be even more pressure to maximize the thermal capacity of existing transmission lines. The actual cost of line outages for maintenance of rebuild work will make many present day work procedures obsolete. Thus, the industry is changing to methods of safely increasing the existing structure heights without removing the line from service. One such method is the PhaseRaiser^® System.
