(P1; see FIG. 2) may also be formed to protrude.

The support part 350 may protrude from the lower end of the band protrusion P2 in a reverse direction and a lower direction in the first direction. For example, the support part 350 may protrude from the lower ends of the band body P1 and the band protrusion P2 toward the electric pole 1 and in the lower direction. The support part 350 is in contact with the electric pole 1 between the electric pole 1 and the pole transformer 2 (see FIG. 1 ) and can support the hanger band 300 .

In this embodiment, it is illustrated that the hanger band 300 is formed by combining four pieces P1 and P2. In the vicinity of the bonding site between the fragments P1 and P2 of the hanger band 300, the electric pole 1 and the hanger band 300 may not be in close contact with each other and space may be generated due to being spaced apart.

As this space becomes larger, the contact surface between the electric pole 1 and the hanger band 300 is reduced, and as a result, the coupling force between the electric pole 1 and the hanger band 300 is weakened and the hanger band 100 becomes the electric pole (1). slipping may occur.

In consideration of this point, in the present embodiment, the support part 350 is provided under the band protrusion P2.

The space generated near the bonding site between the fragments P1 and P2 of the hanger band 300 may be said to be generated in the vicinity of the band protrusion P2 after all. In consideration of this point, the support part 350 is provided under the band protrusion P2.

The electric pole 1 is affected by the torque acting on the hanger band 300 due to the weight of the pole transformer 2 , and the influence of this torque may be distributed by the support part 350 .

According to this, the force applied due to the torque acting on the hanger band 300 due to the weight of the pole transformer 2 may act on the electric pole 1 through the support part 350 .

At this time, the support part 350 allows the force applied due to the torque acting on the hanger band 300 to be dispersed through the support part 350 and to act in the form of pressing the electric pole 1, so that the hanger band 300 and It is possible to effectively prevent the hanger band 300 from sliding from the electric pole, as well as to allow the pole transformer 2 coupled thereto to be fixed more stably.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above specific embodiments, and can be manufactured in various different forms, and those of ordinary skill in the art to which the present invention pertains will appreciate the technical spirit of the present invention. However, it will be understood that the invention may be embodied in other specific forms without changing essential features. Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
