る。 Conventionally, this type of jumper device has a rigid jumper rod with electrical conductivity that extends in a substantially horizontal direction placed below the tower arm, a hanging member that connects the end of the jumper rod to a yoke, and a connection that connects the jumper rod and the main line. It is known that it consists of a conductor.

を小さくし得、もつて鉄塔を小型化し得る利点が
ある。 This jumper device uses a rigid jumper rod, such as an aluminum pipe, that has conductivity and extends in a substantially horizontal direction, so there is little sag, and therefore the spacing between the tower arms and the ground below can be reduced. This has the advantage that the tower can be made smaller.

くする必要が生ずる欠点があつた。 However, since this rigid jumper rod is supported at both ends by hanging members, the jumper rod flexes in its center due to its own weight, which has the disadvantage that it becomes necessary to increase the distance between the tower arms and the distance between the ground.
本発明は、このような欠点を改良したものであ

得る等の利点を有する。 However, according to the jumper device for overhead power transmission lines of the present invention, the weight is attached to the end of the jumper rod, and the attachment part of the hanging member connected to the weight is located inside the center of gravity of the weight. The moment due to the weight of the weight with the mounting part of the material as a fulcrum acts in the direction of reducing the deflection of the jumper rod due to its own weight. Therefore, the deflection of the jumper rod due to its own weight is reduced, and the spacing between the tower arms and the ground can be reduced accordingly. It has the advantage of being able to downsize the steel tower.

明の効果が発揮されることは勿論である。 The above has described an example in which a weight is attached to a rigid jumper rod with main wires connected to both ends as shown in Fig. 1, but it is also possible to apply a jumper device in which jumper wires with main wires connected to each other are attached to a rigid jumper rod using a spacer. It goes without saying that the effects of the present invention can also be achieved even if weights are attached to both ends of the jumper and the attachment portion of the hanging material is provided inside the center of gravity of the weights.
