PROBLEM TO BE SOLVED: To improve work efficiency in a steel-tower such as the switching work of a power feeding system, by insulation-protecting a conductor for a jumper, and releasing the connection of the conductor for the jumper.SOLUTION: A jumper device 1 includes a primary side connecting body 2 connected to a primary side electric wire K1 supported by a steel-tower P through an insulator G so as to be energized; a secondary side connecting body 3 connected to a secondary side electric wire K2 supported by the steel-tower P through the insulator G to be energized; a conductor 4 which extends in one direction and connects the primary side connecting body 2 and the secondary side connecting body 3 so as to be energized; and an insulation coating body 5 which coats the conductor 4. While the connection of the primary side connecting body 2 to the primary side electric wire K1, the connection of the secondary connecting body 3 to the secondary side electric wire K2, and the coupling of the primary side connecting body 2 and the secondary side connecting body 3 to the conductor 4 are released, the conductor 4 and the insulation coating body 5 are configured so as to relatively move in one direction.SELECTED DRAWING: Figure 1 |
