The present invention relates to a mixed grounding module of graphite, perlite, and vermiculite, comprising: a bar-shaped first grounding body; a second grounding body integrally formed on the outside surface of the first grounding body; and a conductive core rod connected to the first grounding body. The first grounding body consists of 80-90 wt% of salt, and 10-20 wt% of expanded vermiculite. The second grounding body consists of 10-20 wt% of expanded perlite, 10-20 wt% of expanded vermiculite, 30-40 wt% of graphite, and 30-40 wt% of cement. Accordingly, a very light grounding module can be manufactured by expanded vermiculite of the first grounding body, and expanded perlite and expanded vermiculite of the second grounding body. |
