<p>PURPOSE:To have a distance between a jumper device and a tower cope with voltage elevation by a method wherein a jumper wire is connected to the end of a space keeping member to be held outward from the tower side and the space keeping member is fixed by a fixing member. CONSTITUTION:The one side ends of space keeping members 4 and 4 are connected to jumper wires 3 and 3 and the other ends are connected to the conducting side construction members of insulator devices B1 and B1. Protruding pieces 5 and 5 which protrude upward are provided on the other end sides of the space keeping devices 4 and 4, i.e., on the conducting side construction members of the insulator devices B1 and B1 so as to be in one piece with the space keeping members 4 and 4 and a fixing member 6 is provided on the top ends of both the protruding pieces 5 and 5. Both the side parts of the fixing member 6 are composed of filled long-rod insulators 7a and 7b and the middle part is composed of a coupling rod 7 which couples both the long-rod insulators 7a and 7b with each other to provide an electrically non-conducting structure. With this constitution, the jumper wires can be detoured horizontally and a transmission capacity can be increased by utilizing an existing tower.</p> |
