2. The cylindrical grounding module has hygroscopic properties, low grounding resistance and can maintain long-term stability. In areas with high soil resistivity, it can reduce the grounding resistance of the grounding grid and reduce the excavation area of the grounding grid;
3. After multiple large current shocks, the resistance does not increase, and no hardening or breakage occurs; it can withstand low temperatures of -40°C, and is also suitable for northern alpine regions;
4. The cylindrical grounding module has a built-in metal pole core, which is connected to the ground wire of the protected object to discharge the ground current to the earth.
5. Graphite is used as a carrier in the cylindrical grounding module, and various materials such as ion slow-release agent, water-retaining agent, and coagulant are added. Its hollow structure can form good contact with various types of soil and rocks, allowing it to be in contact with the soil. The contact area increases exponentially.
