<p>PROBLEM TO BE SOLVED: To enable a system dividing work, which is performed for opening a jumper device when an electrical accident occurs in a transmission and distribution system, to carry out easily and quickly. SOLUTION: In a jumper device 11, which electrically connects transmission lines 2 anchored to the steel crossarm 1 of a steel tower via anchor clamps 3 and tension insulator strings 6 on both sides of the steel tower to each other, via a jumper conductor 5 both ends of which are electrically connected to the anchor clamps 3, where both ends of the jumper conductor 5 being respectively connected to the clamps 3 on both sides of the steel tower via jumper sockets 14 each of which is composed of a jumper socket main body section 16 joined to one of the clamps 3 and an attaching/detaching clamp section 17, which is provided on the outlet side of the main body section 16 and attachably/ detachably grasps the conductor 5. The work for attaching and detaching the conductor 5 to and from the clamp sections 17 of the jumper sockets 14 can be carried out easily and efficiently, for reasons of hand-held parts being light- weight, and the like, and therefore, system division can be made quickly.</p> |
