Is pressed one by one, there is no reference to keep the arc, and when the nut 42 is tightened, it is not evenly tightened and the surface pressure at one place becomes large. Therefore, as shown in FIG. The shape may be deformed into a triangular shape. If the true circle of the sheath 1 near the sheath end is deformed, it becomes impossible or insufficient to insert the sheath between the conduit cables 101, and it is likely that welding connection becomes impossible or welding defects occur. In addition, when the conductor supporting jig 21 is assembled to support the aluminum conductor 2 because the bolt 40 and the holding metal 41 are not mechanically connected to each other, these may come off or fall apart. There is also a problem in workability, such as becoming inconvenient.

の内側に押し付けるようになっている。An embodiment of the present invention according to claim 2 will be described next with reference to FIG. The difference between FIG. 1 and FIG. 2 is that in FIG. 2, the attachment by the elongated hole 9 is reduced by one, and the connection role is changed to the bolt 16, the nut 18 and the through bolt 6 holding the band piece 3. This is possible at 2 to 4 where N is small. FIG. 2 shows a structure where N = 2. As shown in FIG. 2, the conductor supporting jig 21 of the present invention includes a band piece 3 divided into two pieces sandwiching an aluminum conductor 2 and two pieces 4 of a sufficient size to cover the inner surface of the sheath 1. The band pieces 3 are connected to each other by bolts 16 and nuts 18. The pieces 4 are shifted by 90 degrees so that the seam is located at the center of the band 3. A flange is provided on both the band piece 3 and the show piece 4, and a long hole 9 is provided on the flange on the show piece 4, and a screw hole 23 is formed in the flange on the band piece 3, and tightened with the bolt 10. It is configured to be. If the bolt 10 is loosened, the gap of the shoe piece 4 can be adjusted manually, and if the bolt 10 is tightened, the shoe piece 4 and the band piece 3 are fixed. This portion corresponds to a movable connecting portion. Only one shoe piece 4 is combined with one band piece 3, and a plurality of elongated holes 9 of the guide portion may be provided in the same combination in the same direction. The direction of the slot 9 is desirably the split direction of the band piece 3 at the center of the show piece 4. Then, at least one or more appropriate number of push bolts 6 are screwed into the screw holes 24 of the bolt mounting portions 8 provided on the flanges of the screw pieces 4 on the screw pieces 4,
Is rotated to increase the distance between the band piece 3 and the show piece 4 via the bolt cap 7 at the tip, thereby increasing the show piece 4
To the outside, that is, to insert the piece 4 into the sheath 1
It is designed to be pressed inside.

By loosely connecting them with bolts 16 and nuts 18, a loop of the band piece 3 and the shoe piece 4 is formed. Then, the bolt 4 is screwed into the screw hole 23 of the flange of the band piece 3 through the elongated hole 9 so as to temporarily connect the mesh piece 4 and the band piece 3 so that the joint of the piece 4 is located near the center of the band piece 3. I do. The bolt 10 is positioned inside (in the direction of the conductor) inside the elongated hole 9, and the screw pieces 4 approach each other and are lightly tightened.
At this time, the bolt 6 is screwed into the helical hole 24 of the bolt attachment portion 8 provided on the shoe piece 4. At this time, the insertion length of the bolt 6 is made short so that a gap is formed between the band piece 3 and the tip of the bolt 6.

Lightly tighten 0. In this way, the inner band piece 3 has a larger diameter and the outer shoe piece 4 has a smaller diameter.
With the bolt 10 as a fulcrum, the shoe piece 4 is stabilized while being supported by the bolt 6 (the bolt marked D in the figure) which is balanced by contacting the band piece 3 side of the bolt 6. deep. The conductor support jig 21 is inserted into the end of the conduit air cable 101, and the bolt 16
The band pieces 3 are fixed to the aluminum conductor 2 by tightening the nuts 18. Next, the screw 4 is enlarged by hand, the screw 4 is attached to the sheath 1, the bolt 10 is slightly tightened, the bolt 6 is turned, and the tip of the bolt 6 is passed through the bolt cap 7 provided on the band 3. After confirming that the piece 3 has been reached, the bolt 6 is moved in the direction of pressing against the sheath 1, and the shower piece 4 is pressed against the sheath 1. Finally bolt 1
0 is completely tightened to fix the band piece 3 and the show piece 4 to complete the mounting operation.

The example of dividing into individual pieces has been described. However, when the size of the gas insulating device is increased, the assembly is facilitated by dividing into three parts, four parts, etc. (N divisions), and the pressure on the inner surface of the sheath 1 by the shower pieces 4 is made more uniform over the entire surface. And the deformation of the sheath 1 can be further prevented.

が出てくる。As described above, according to the first aspect of the present invention,
According to the conductor support 21 of the present invention, the connection of the bolts of the elongated holes 9 turns the shower pieces 4 and the band pieces 3 into a loop, so that they are all integrated, so that the handling is easy and the transport during handling is easy. In addition, there is no need for any special processing, and there is no portion where the bolts and the holding metal, which are the conventional problems, come off. Further, since the shoe piece 4 can be concentrically enlarged and reduced at the position of the elongated hole, the sheath 1 can be uniformly tightened,
The deformation of the sheath 1 can be suppressed. Since the band piece 3 and the show piece 4 are combined and integrated, when the conductor support 21 is assembled and the conductor 2 is supported, one-person work is possible. Since the band piece 3 and the shoe piece 4 have a flange structure, they are structurally strong and do not deform. According to the second aspect of the present invention, it is possible to omit the processing of the long hole by half.
However, there is a defect that handling precautions increase during transportation and installation.
