PURPOSE: A jumper wire connection fixing apparatus for overhead transmission lines is provided to connect and fix an insulator, jumper wire, and power transmission overhead line with stable protection thereof, thereby enabling to fix the insulator and jumper wire in strong wind. CONSTITUTION: An empty space is formed inside of a first main body(21) with openings in front and rear surfaces. A first mounting part(22) is formed with bending in horizontal direction toward inside in the upper end part of both vertical walls of the first main body. A coupling plane(10) is mounted in the upper end part of a jaw(11) and coupled to an outer side surface of a power transmission tower(1). A bottom fixing part(20) is formed in the bottom surface of the first mounting part and penetrates through a penetration hole(12) of the jaw and is comprised of a first spiral coupling part(23) fixed in the jaw using a screw nut in which helix is formed in the outer circumference. An empty space is formed inside of a second main body(31) with openings in front and rear surfaces. An installation hole(32) penetrates in up and down direction on the bottom surface of the second main body. A second mounting part(33) is formed with bending in horizontal direction toward outside in the upper end part of both vertical walls of the second main body. A upper fixing part(30) is formed in the bottom surface of the second mounting part and penetrates through a penetration hole of the jaw and is comprised of a second spiral coupling part(34) fixed in the jaw using a screw nut. |
