A support structure for a power transmission line in a power transmission tower is provided to move a frame structure along a length direction of a fixing frame by loosening a fastening bolt. An insertion portion of a support structure includes a telegraph pole and a rotation shaft. A support portion includes a central groove, a pair of insertion bosses, and a support frame. The insertion bosses have plural through-holes thereon and are fixed to be apart from each other. A frame structure(100) includes an electrical insulator, a fixing mount(120), first and second fixing frames(140,140'), first and second presses(130,130'), and first and second coating materials(150,150'). The electric insulator includes an insertion hole, to which a fixing bar is rotatably inserted. The fixing mount includes a screw for the electric insulator and a cushion unit, which is made of a synthetic resin material. When a fastening bolt is fastened, the first and second presses fix the fixing mount by attaching curved portions of the first and second fixing frames to each other. When a fastening nut of the screw is fastened, the first and second fixing frames are coupled with each other. The first and second coating materials are applied on contact surfaces of the first and second fixing frames, which are contacted with the fixing mount and the first and second presses. |
