Abstract The metallic grounding materials used in power system nowadays have faced with lots of problems, such as corrosion, the difficulty of transportation and construction, easy to be stolen and high cost, and so on. Thus, a new type of grounding material, i.e. flexible graphite composite grounding material, was proposed and produced. Firstly, the material composition of the material was illustrated in this paper. Secondly, the skin effects and the inductive effects of the graphite composite grounding materials with copper and steel were calculated by finite element method respectively. And then the expanding graphite composite grounding material was made. At last, through the application in 110kV and 220kV transmission line tower grounding grid, it is shown that the new grounding material can meet the requirements of practical engineering.

Key words： Corrosion of grounding material flexible graphite composite electrical grounding material skin effect inductive effect expanding graphite composite grounding material
