A ground apparatus of a distribution line is provided to improve grounding effect by having a plurality of extending ground rods horizontally inserted into ground bars to be conducted. Ground bars(10,10a,10b,10c) are installed on an outer peripheral surface of an electric pole to support the electric pole and inserted into a ground support(20). Each of the ground bars is a long rectangular plate body formed by wrapping a conducting rod with plastic insulating rubber and has an upper end bolt(11a) protruded from the conducting rod, left and right anchor bolts(11b,11c) obliquely protruded at upper left and right sides, a fixing piece having anchor holes and fixed by a nut, and a plurality of elastic grooves formed at a lower end and having contact balls elastically protruded outward by springs. The ground support fixes the electric pole and the ground bars while being conducted and has an electric pole insertion hole formed at a center to insert a lower end of the electric pole, ground bar insertion holes formed around the electric pole insertion hole to insert the ground bars, ball grooves formed at lower ends of the ground bar insertion holes to insert the contact balls elastically, and insertion grooves formed around a downward inclined surface. An extending ground rod(30) is installed at a lower end of the ground support to be extended to the ground in all directions and has ground rods(31,31a,31b,31c) received in the insertion grooves of the ground support to be extended outward. An insulating cover(40) insulates an upper surface and an outer peripheral surface of the ground support. |
