DISTRIBUTION LINE SUPPORTING METAL BAR STRUCTURE OF ELECTRIC POLE The present invention relates to a distribution line supporting metal bar structure of an electric pole, which is improved to expand a lifespan of each part by preventing impacts from being delivered to an insulator or each connection part even when a power distribution line judders by wind or the like. The distribution lien supporting metal bar structure, for installing a fastening rod connected with an insulator or a power distribution line on a metal bar in an electric pole, comprises: a metal bar attached to the electric pole; a joint member assembled to the metal bar, with a side protruding outwards; and a fastening rod which is combined to the joint member, and to which the insulator and the power distribution line are attached, wherein: the metal bar is divided into two, each having a ring-shaped clamping unit an expended portion at a lateral end, protruding pieces formed at both sides of the clamping unit, and a supporting member attached to the bottom end of the expended portion to maintain intervals between jumper wires; the metal bar is installed by a fixing bolt inserted into the protruding pieces; at a side of a body of the fastening rod, a catching piece, of which elasticity is maintained by a spring, is coupled to a screw part and moves horizontally within the expended portion, and, at the other side of the body, a connecting piece having a through-hole is formed; a connecting ring is formed at a lateral end of the fastening rod; and the fastening rod becomes able to rotate around the fixing bolt as the connecting ring being coupled to the connecting piece of the joint member. |
