[0002] With the development of social power system, its grounding system is extremely important. The power grounding system is an important power facility to ensure the safe operation of power equipment and the safety of personnel. The grounding system mostly uses metal grounding materials. Usually, the metal grounding body is easily corroded. If the inspection is not timely, the corrosion of the grounding system will cause serious power accidents to the power system and nearby personnel.

[0003] Graphite has good conductivity and impact current tolerance, stable structure under large current impact, reliable corrosion resistance, long service life, and no pollution to the soil. It is an ideal material for grounding electrodes. As the length of the vertical grounding body increases, its grounding resistance will decrease, which can better meet the grounding resistance requirements.

[0008] Preferably, the outermost layer of the grounding module body is provided with a resistance reduction layer, and a graphite braided layer is provided inside the resistance reduction layer.

[0009] Preferably, the positioning device comprises a connecting block and an insert rod arranged on the connecting block, the connecting block is provided with a threaded hole, and the upper end of the insert rod is provided with an external thread matched with the threaded hole.
