A jumper cable clamp apparatus for an overhead transmission line is provided to maintain a gap state safely between a jumper cable and the overhead transmission line irrespective of a change of the slope of an insulator and a wind by installing the jumper cable elastically. A jumper cable clamp apparatus for an overhead transmission line includes front/rear/left/right polymer insulation fixing units(10,10c), front/rear/left/right supporting bars(20,20c), a couple of front/rear jumper cable supporting tubes(30,30c), an upper supporting rod(40), a lower supporting rod(50), and an elastic spring(60). An internal uneven unit which is opposite to an outer appearance of a polymer insulator and is fixed is formed inside the front/rear/left/right polymer insulation fixing units. A connection protrusion unit having a bolt hole is formed on a lower part of front/rear/left/right polymer insulation fixing units. A penetration hole is formed on an end of front/rear/left/right supporting bars. A bolt unit which is fixed by a nut is formed on the other end of front/rear/left/right supporting bars. The jumper cable supporting tubes have supporting plates having a penetration hole. A semi circular tube is fixed on a central part of the supporting plate. The couple of front/rear jumper cable supporting tubes are located to be opposite to each other. A front end of the upper supporting bar is fixed by a connection nut. The lower supporting bar penetrates and supports a penetration hole of a lower side of the couple of front/rear supporting bars. The elastic spring is installed on the upper/lower supporting bars between the couple of front/rear jumper supporting tubes. |
