<p>PURPOSE:To prevent a mechanical damage to a jumper device and the occurrence of a flashover between the arm of a steel tower and rigid member by supporting the rigid member by means of a plurality of supporting members arranged at intervals in the length direction of the rigid body so that the vibration of the rigid body in the length direction can be suppressed even when galloping, etc., takes place. CONSTITUTION:Supporting members 2 support both ends of a rigid member 1. In addition, the member 1 is extended by respectively fixing extension members 10 to both ends of the member 1 and one ends of supporting members 12 are fitted to the ends of the members 10. The other ends of the members 12 are fitted to insulator string yokes 4. As a result, the member 1 is restricted in movement in its length direction due the pulling forces of the plurality of supporting members 2 and 12, since both ends of the member 1 are supported by the members 2 and 12 at intervals. Therefore, the vibration of the rigid member in its length direction can be suppressed and, accordingly, a damage to a jumper device and the occurrence of a line-to ground fault can be prevented.</p> |
