What is a lightning protection grounding rod

Time:2022-08-13

Lightning protection grounding rod, also known as grounding electrode or grounding grid, is designed and produced based on the theoretical basis of improving the internal conductivity of grounding conductors and reducing the external soil resistivity of grounding conductors. The product has the advantages of easy construction, small footprint, no environmental pollution, long service life, and low resistance. Below, the editor from the flexible graphite grounding strip manufacturer will lead you to understand it together.


This system is widely applicable in many fields such as communication, power, transportation, finance, petrochemicals, and building systems. For units and departments with strict grounding requirements, such as communication bureaus (stations), mobile base stations, dispatch rooms, substations, highway facilities, computer rooms, intelligent communities, etc., adopting this system can form a high-performance grounding system. Copper clad steel materials have been widely used in grounding devices due to their good conductivity, high mechanical strength, and especially the excellent corrosion resistance of the externally coated copper layer. In relevant standards, countries such as the United States, the United Kingdom, and Germany stipulate that both grounding bodies and grounding wires can be made of copper-clad steel composite materials. The editor of the flexible graphite grounding strip manufacturer learned that in China, the corrosion resistance and reliability of grounding devices have been increasingly valued, and copper-clad steel composite materials have been used as a substitute.


Classification of lightning protection grounding rods

1. Copper plated grounding rod: A copper layer with a thickness of 0.254mm or more is coated on the outside of the grounding steel rod, which is called a copper plated grounding rod, also known as a copper coated steel grounding rod, etc;

2. Galvanized grounding rod: hot-dip galvanized anti-corrosion treatment is carried out on the outside of the steel rod;

3. Graphite grounding rod: PTD-1 type rod-shaped grounding module made of graphite material;

4. Plasma grounding rod: The internal filling material contains a specially designed electric ion compound that can fully absorb the moisture in the soil.

The editor of the flexible graphite grounding strip manufacturer reminds everyone that when designing grounding systems, we must consider soil conditions to make the best choice. The foundation of grounding system design is the precise measurement of soil in order to understand the resistance coefficient of soil in different geological layers. With these data, we can determine from a technical and economic perspective which grounding system is the best. One important thing is that the distance between the vertical rods should be at least equal to the length L of the installed rods, but not more than 10 meters. With the above conditions, it can be confirmed that the grounding rods we choose will be effective for many years.
