流を逃し、設備破損を防止する。In a jumper device used to connect transmission lines having different diameters in the tension tower, a suspended prefabricated jumper device using a horizontal member and a pipe between jumper wires has been put into practical use. Since this is fixed in shape, a horn for insulation coordination is configured in a jumper device. (The inside of the jumper is hardly affected by snow cover.) FIG. 3 shows an example of the horizontal member of the suspension type jumper device; a jumper horn 2 is provided at the center of the pipe, and the ground side attached to the lower surface of the tower arm. Insulation coordination is achieved with a horn (impulse horn) 1 '. Therefore, when a large current such as lightning flows, discharge is caused between the facing horns 1 and 1 'to escape the large current and prevent equipment damage.
