Abstract:
A method for repairing an energized high voltage powerline conductor supported by a tower while maintaining a lineman bonded to the high voltage powerline conductor at positions spaced outside a flashover area extending for a flashover distance around said tower which includes:transporting a lineman by helicopter to the tower and offloading the lineman onto the tower, lowering to said lineman from the helicopter a unitary ladder having a first section which is at least equal in length to said flashover distance and a second section which extends at an angle of at least ninety degrees from said first section to a base, attachment by the lineman of the first section to the tower and positioning by the lineman of the second section base on the energized high voltage powerline conductor, descent over the ladder from the tower by the lineman to the base, electrically bonding to the energized high voltage powerline conductor by the lineman from the second section, and movement by the lineman after bonding from the second section onto the energized high voltage powerline conductor.
