그 다음 케이블클램프(42)(44)의 상단에 형성되어 있는 후크부(42a)(44a)에 케이블결속선(도시 생략)을 걸어서 전력케이블(22)을 결속하게 되면, 전력케이블(22)이 케이블지지판(40)으로부터 이탈되는 것을 방지할 수 있다.Then, when the cable ties (not shown) are hooked to the hook portions 42a and 44a formed at the upper ends of the cable clamps 42 and 44, the power cable 22 is bound. Deviation from the cable support plate 40 can be prevented.

위와 같이 전력케이블(22)이 케이블지지판(40)에 올려진 상태에서 전력케이블(22)이 지니고 있는 자중에 의해 행거(20)와 행거(20) 사이에서 처짐이 발생되려고 하지만 행거(20)와 행거(20) 사이에 설치된 와이어(50)(52)의 인장력에 의해 전력케이블(22)이 현수교 형태로 지지되어 처짐이 방지된다.In the state in which the power cable 22 is placed on the cable support plate 40 as described above, sagging occurs between the hanger 20 and the hanger 20 due to the weight of the power cable 22. The power cable 22 is supported in the form of a suspension bridge by the tension of the wires 50 and 52 provided between the hangers 20 to prevent sagging.
