しくない。By the way, as shown in FIG. 6, the projecting direction of the tower arm 1a (vertical direction in FIG. 6).
In the case of a tension-resistant steel tower with a large angle formed by the tension-resistant insulator string 6 with respect to the direction orthogonal to the
Since there is a difference ΔL in length between the outside and the tension-resistant insulator string 6,
As shown briefly in FIG. 6 and shown in detail in FIG. 5, the yoke 5 is in a tilted state (the tilted angle of the yoke 5 is indicated by α). The inclination of the yoke 5 naturally causes an imbalance in tension between the two tension insulator chains 6, and also causes the clevis or the like to be twisted to cause breakage.
In addition, inconvenience that the vicinity of the end of the flexible jumper portion 9 on the side of the detention clamp 3 cross-contacts the other electric wire 2, or
There are also drawbacks such as the inconvenience that the length of the flexible jumper portion 9 is different depending on the electric wire 2 on the outside, which hinders the work of forming the flexible jumper portion 9 and prefabrication. Further, when the horizontal angle is not so large, the inclination of the yoke 5 is not so large, so in the past, the jumper wire 7 was attached as it is, but in recent years, the horizontal angle is required due to difficulty in obtaining a site. In many cases, there is no choice but to increase the size, and if the jumper wire 7 is attached to the inclined yoke 5 as it is, a problem may occur in the separation from the tension insulator string 6 when rolling. Furthermore, due to the tilting of the yoke 5,
There is also a problem that misalignment (relative displacement of the tips of both arc horns viewed from the longitudinal direction of the insulator) occurs between the opposing arc horns 11 and 12, and insulation coordination differs from the design. Further, it is not preferable in appearance that the yoke 5 is inclined.
