(Attaching the clamp) The clamp A is attached to the wire a in the clamp body 1 at a predetermined position of the wire a measured in the drum field on the ground.
Is inserted between a pair of wedges 5a and 5b, and is attached. A protective bracket (not shown) is attached and the wire is extended. Then, after tightening on the tower, the protective fittings are removed and attached to the connecting fittings, completing the work. After connecting to the insulator ream with connecting metal fittings, the jumper metal fitting 6 is mounted, the electric wire a of the jumper part is mounted, and the jumper wire is formed.

[Effect] A clamp body 1 having a narrow rectangular shape in plan view.
The connecting plate 3 is fixed to both sides of the clamp in parallel with a plurality of small-sized bolts 7a, so that the width of the clamp in the lateral direction can be remarkably reduced as compared with the conventional case, and the connecting plate 3 is shortened. Therefore, even when the clamp body 1 and the connecting portion are integrated, the clamp body 1 can pass through the inside of an aluminum wheel with a diameter of 600 mm when being extended. In addition, a connection fitting (not shown) that is connected to the revolving part by the insulator may be used for the portion where the connection plate is shortened. Since such a clamp is used, it is possible to prevent the clamp body 1 and the connecting plate 3 from being bent by attaching an elliptical metal protective bracket covering the entire clamp, and to smooth the inside of the wheel.
Can be passed through. Thus, after pre-assembly on the ground, the wedge pushing work on the tower is no longer necessary, so a complete cam-alongless construction method can be adopted, and safe and efficient work has become possible.
