FIG. 1 shows an example in which the present invention is applied in a case where the overhead power transmission lines 1 of each phase are each a single conductor. As shown in the figure, overhead power transmission lines 1 installed over the same span are connected by a first type interphase spacer 2 and a second type interphase spacer 3 adjacent in the line direction. At least one pair of these spacers 3.4 are provided in the same span. In addition, these mutual spacers 2 and 3 may be provided apart from each other instead of adjacent to each other, for example, when the span is narrow. In the first type interphase spacer 2, a plurality of insulators 4 made of insulators etc. arranged in a row are connected by a connecting part 5, and wire gripping fittings 6 are connected to both ends of the insulators 4 through another connecting part 5, respectively. It has a built-in structure. In particular, each connecting portion 5
The connecting plate 7 whose plate surface is parallel to the plane containing the overhead power transmission line 1 is connected between the insulators 4 and between the insulators 4 and the wire gripping fitting 6.
The connecting plate 7 is connected to the insulator 4 or wire gripping fitting 6 on both sides by connecting pins 8. Such a connecting portion 5 is formed from the direction of the connecting plate material 7.

Therefore, even the first type interphase spacer 2 is easy to bend in the direction of the plane including the overhead power transmission line 1, and difficult to bend in other directions. The wire gripping fitting 6 is a wire protection wire @9 wrapped around the outer circumference of the overhead power transmission line 1.
The overhead power transmission line 1 is gripped from the outer periphery of the handle.
