    摘要： The present invention provides a low-resistance carbon grounding module and a method for manufacturing the same, which can increase strength for durability against external environmental changes by varying the type and mixing ratio of raw materials for a carbon resistor without using any heat source. The low-resistance carbon grounding module comprises a carbon resistor extending in the longitudinal direction thereof and a conductive core bar installed in the center of the transverse section of the carbon resistor, wherein the carbon resistor comprises graphite, cement, and feldspar. Thus, it is possible to prevent the durability from being deteriorated due to external environmental changes, water, or electrical resistance, thus improving the quality and reliability of the product while minimizing the production of CO 2 .
