In the three-point supporting double tension device 52, the insulator side yoke 36 of the ground side balance yoke 37 also functions as the ground side double yoke of the double tension device. The parallel clevis 11 and the ground side 2 of the three-point support twin tension device 51 shown in FIG.
The continuous yoke 12 becomes unnecessary, and the length of the apparatus can be shortened. For this reason, the compression clamp 88 of the triple tension device 71 of the old device is diverted to the electric wire clamp 88 while the electric wire is clamped, and the wire side yoke is independent vertical and horizontal yokes. Even if it is configured, it can have the same length as the old three-unit tension device with a margin, so that the work of adjusting the sag when the electric wire is stretched becomes unnecessary.

The three-point supporting double tension device 52 shown in FIG.
The configuration other than the ground vernier bracket 35, the ground side balance yoke 37 and the line side yokes 39, 41, 45 is substantially the same as that shown in FIG. Ground side balance yoke 3 shown in FIG.
Reference numeral 7 denotes a ratio twice as large as that shown in FIG. 1 between two juxtaposed yokes 4 and 4 and the inner side between both connecting metal fittings connecting points 5 and 5 of each yoke 4. And two parallel links 7, 7 having the same length and one end connected to the intermediate connection point 6, and a yoke 36 on the insulator side connected to the other end of the two parallel links 7, 7 taken in parallel. The yoke 36 on the insulator side
Is connected to the ground side of the double tension device by connecting the double insulator rows 16 and 16. Therefore, FIG.
The horizontal yoke 8 and the parallel clevis 11 shown in FIG. 1 are not required, and the length of the apparatus can be shortened.
As shown in FIG. 1 (b), ground side vernier brackets 35, 35, 35 for tilting the side-by-side yokes 4, 4 and the horizontal yoke 36 in a direction having a horizontal angle are required. However,
As shown in FIG. 9, the ground side vernier bracket 35 can be used with a short length, so that the ground side yoke connecting point of the two insulator trains 16, 16 is connected to the mounting point of the support arm 72. 1,1,1
Is shorter than that of the three-point supporting double tension device 51 shown in FIG. For this reason, when the compression clamp 88 of the old triple tension device 71 is diverted to the electric wire clamp while the electric wire is clamped, and when the same length as the triple tension device 71 is used, the adjustment of the wire sag adjustment is omitted. The side yoke is a multi-conductor fixed yoke 20 in the three-point supporting double tension device 51 shown in FIG.
However, this can be constituted by a vertical yoke 39 and horizontal yokes 41 and 45 which are independent from each other.

The ground-side balance yoke 14, which is composed of two juxtaposed yokes 4, 4 and a pair of parallel links 7, 7 and a horizontal yoke 8, is constituted by an offset zero yoke. Side 2
Since the total load acts on the middle point 10 of the horizontal yoke 8 even if the loads applied to the two connecting points of the insulators of the continuous yoke 12 are different, the three mounting points 1, 1, 1 of the existing support arm are provided. With 1 the load can be shared equally and no imbalance occurs. FIG.
As shown in FIG. 10 (b), not only the mounting position having a horizontal angle of zero as shown in FIG. 10 (a) but also the mounting position having a horizontal angle as shown in FIG. Since the yoke 8 is always parallel to the straight line connecting the mounting points 1, 1, 1 of the existing support arm 72, the ground side vernier bracket is unnecessary regardless of the presence or absence of the horizontal angle.

The ground side balance yoke 37 is provided with two yokes 4 and 4 arranged side by side, a pair of parallel links 7, 7 and the insulator side serving as the ground side double yoke of the double tension device. Except for the point constituted by the yoke 36 and the configuration of the line-side yoke, the structure is substantially the same as that of the three-point supporting double tension device 55 shown in FIG. As a result, the one shown in FIG. 2 has more ground side vernier brackets 35 than the one shown in FIG. 1, but the intermediate yoke 8 and the single link 11 are unnecessary. As shown in FIG. 9, the ground side vernier bracket 35 has one of four bolt holes 31 of one substantially trapezoidal adjustment piece 30 and a pair of fan-shaped adjustment pieces 32 sandwiching the adjustment piece 30. The length of the vernier bracket is relatively short because one of the bolt holes 50 arranged in an arc is connected to the 32 reference bolt holes 33 by bolts. For this reason,

The three-point supporting tension devices 51 and 52 shown in FIGS. 1 and 2 are connected to the electric wire clamp 88 by the triple tension device 71 in the replacement work with the triple tension device 71 shown in FIG.
The compression clamp is used with the wire clamped, and has the same length as the triple tension device 71 so that the wire slackness does not change even if the tension device is replaced. For this reason, when the device length is longer than the triple tension device 71, the three-point supporting double tension device 51 shown in FIG. By doing so, the length is made the same as the triple tension device 71. The three-point supporting double tension device 52 shown in FIG. 2 has a shorter device length than that of FIG. 1, and separates the yoke on the line side from the vertical yoke 39 and the horizontal yoke 41, 4 independent of each other.
5 can be the same length as the triple tension device.

Although the lengths of the ground side vernier brackets 35, 35, 35 are adjusted at locations having a horizontal angle as shown in FIG. 11B, the horizontal angle is zero as shown in FIG. Since the lengths of the ground side vernier fittings 35, 35, 35 do not need to be changed at the point (3), the ground side vernier fittings 35, 35, 35 can be omitted.
