A method and system for installing warning spheres on utility power lines using existing commercial drones and an unique preassembled warning sphere with an inverted U shape opening in its lower half, one or more cable clamp in the upper part of the inverted U which matches the utility cable's diameter, number of strands and longitudinal spiral pitch. The warning sphere also has two receptacles in its circumference for catching the drones retractable landing gears fitted with matching bulges, enabling the safe lifting and flying of the sphere, The Drone also has a 3D stereoscopic camera which is integrated to its video system, thus enabling the precise navigating of the drone directly above the utility cable, and then directing the drone and sphere's U slot and cable clamp into the cable, either manually, or automatically through modulating of the sticks command of the remote control of the drone.
1) A multi rotor remote controlled drone that holds and carries an aerial warning sphere with an inverted U groove in its underside, using its retractable landing gears. Said Drone lifts, flies, navigates said sphere, precisely aiming and lowering said U groove over a utility electric cable, and releasing this sphere by retracting said landing gears thereafter.
5) An aerial warning sphere with an inverted V or U groove in its lower half, where a plastic or other flexible material clamp is attached to the top of said groove. Said clamp is further matched it its diameter and opening to the exact diameter of the utility electric cable to allow fitting upon pressure in the order of half of the drone self weight, and also has radial grooves in its circumference that circles the cable, matching the exact strands diameter and spiraling pitch of said strands. Such exact matching enables “perfect match” between clamp and cable, preventing gravitational longitudinal sliding, or wind induced rotation of said sphere on said cable.
