Elongate rigid mounting arm and corresponding mounting bracket on one end of the arm, the other end supporting a pivotally mounted insulator depending downwardly from a crank arm, wherein the upper end of the crank arm is attached to an actuator which, upon actuation, pivots the crank arm and insulator about the end of the support arm so as to rotate up and out of the way a energized conductor contained in the wire holder at the bottom end of the insulator. The support arm is temporarily mounted to an existing transmission line tower or pole (collectively herein a tower) so as to extend outwardly substantially horizontally therefrom thereby cantilevering outwardly of the tower the end of the arm supporting the crank arm and insulator. |
