Should a new easement be required to complete the work or install new equipment, a Duke Energy representative will contact the property owner to discuss the necessary documentation. When transmitting alternating current, bundle conductors also avoid the reduction in ampacity of a single large conductor due to the skin effect. On the other hand, the utility is unlikely to install underground lines where development is sparse. Minimum height above areas accessible only to pedestrians, such as porches or decks, is 10 feet. A major goal of overhead power line design is to maintain adequate clearance between energized conductors and the ground so as to prevent dangerous contact with the line, and to provide reliable support for the conductors, resilience to storms, ice loads, earthquakes and other potential damage causes. Towers for support of the lines are made of wood either grown or laminated, steel or aluminum (either lattice structures or tubular poles), concrete, and occasionally reinforced plastics.
