Physically stable petroleum extracts, carbon, graphite and other non-metallic conductor materials are used as the conductive medium of the module, and its conductivity is not affected by the season;
It can absorb moisture, keep effective contact with the soil, and has a low grounding resistance value;
In areas with high soil resistivity, it can effectively reduce the grounding resistance of the ground grid;
1. The bulk density index is not less than 1.68g/cn3.
2. The resistivity index is not greater than 8.5μΩ·m, which is equivalent to a good metal conductor (stainless steel, metal, etc.), which is conducive to the construction of a high-quality ground grid.
3. The ash content index is not more than 0.20%
4. The compressive strength index is not less than 30MPa. In the construction of the grounding grid, it can be fully compacted to improve the discharge of large inrush currents!
5. The flexural strength index is not less than 13.5MPa. In the construction of the grounding grid,
6. The elastic modulus is not more than 10.0CPa.
7. Thermal conductivity (100℃) not less than 90W/(m·K)
8. Thermal expansion coefficient (room temperature to 600℃) not more than 2.8 10-8/℃
9. It has good water absorption and moisturizing performance. Because this product is fired, there are many pores inside the module, which has a good affinity with water and can play a role in water retention. It is especially suitable for grounding in dry soil.
10. It is non-polluting and will not change the surrounding soil, adapting to many special and high-demand environments.
11. Packing in cartons or wooden boxes saves the cost of module transportation.
12. long life, not easy to break, can be used for more than 50 years.
