An electric pole support for laying under the ground is provided to protect a high-voltage cable, to prevent the damage of a high-voltage cable pole and a high-voltage cable, an electric leakage, an electric shock and a short circuit by installing on the outer circumferential surface of the bottom of a high-voltage cable pole. The electric pole support for laying under the ground comprises a subsidence prevention high-voltage cable protective tube(10) fixed to the lower part of a high-voltage cable pole(50), penetrated with a high-voltage cable and composed of a contact unit(11) located on the top of a wedge part(51) of the high-voltage cable pole, a fastening projection projected outward, a subsidence prevention unit(13) folded outward to prevent subsidence, a coupling projection projected toward the high-voltage cable pole and an extension pipe(15) provided with a screw projection, an upper support ring(20) divided into four equal parts to support and fix the upper part of the subsidence prevention high-voltage cable protective tube to the high-voltage cable pole and composed of elastic contact bars formed on two ends, a projection and a groove formed on the front of the elastic contact bars, a contact groove attached with the extension pipe and a screw hole fixed with the screw projection by a nut, a central support ring(30) divided into four equal parts to support and fix the center of the subsidence prevention high-voltage cable protective tube to the high-voltage cable pole and composed of elastic contact bars formed on two ends, a projection and a groove formed on the front of the elastic contact bars, a contact groove attached with the subsidence prevention high-voltage cable protective tube and a fastening hole fixed with the fastening projection by a nut, and a spacer(40) divided into three equal parts to keep the subsidence prevention high-voltage cable protective tube from the high-voltage cable pole at a certain distance and provided with a semi-circular groove to cover the lower part of the subsidence prevention high-voltage cable protective tube and coupled with the coupling projection by a nut and semicircular bolts(44,44a) coupled with a fastening nut(45) to be set on the outer circumferential surface of the high-voltage cable pole. |
