Today, the editor from the ribbon graphite grounding strip manufacturer will talk to you about the soft graphite grounding electrode body, hoping to help you:

Soft graphite grounding electrode and soft graphite grounding module are a new type of non-metallic conductive material with stable performance, low self resistivity, high and low temperature resistance, acid and alkali corrosion resistance, high impact current resistance, and unchanged material properties. The diameter of the soft graphite grounding module is several times larger than that of the soft graphite grounding electrode, and the contact area with the soil is increased. Under the same fault current, the soft graphite grounding module can quickly guide the fault current into the ground. In addition, the soft graphite grounding module is installed on the soft graphite grounding electrode in a multi-channel dispersed arrangement. In areas with frequent lightning, the soft graphite grounding module has a good effect on reducing high current surges. Especially in mountainous areas with inconvenient transportation, no electricity, and high soil resistivity, the combination of soft graphite grounding electrodes and soft graphite grounding modules can better meet design requirements, and construction is simple, reducing excavation volume and costs.

1、 Theoretical and practical basis

1. Principle description; Soft graphite grounding electrode does not contain corrosive ions and mainly relies on electronic conductivity mechanism. The electronic chains are in close contact with each other, with superior conductivity. Electronic conductivity is different from ion conductivity, as it does not rely on water to dissolve ions. Therefore, the soft graphite grounding electrode with electronic conductivity mechanism can be well applied to arid and rainless mountainous areas.

2. Theoretical and practical basis;

(1) The relevant technical requirements for composite grounding bodies in the Technical Conditions for Composite Grounding Bodies (GB/T21698-2008).

(2) The average resistivity of the soft graphite grounding electrode test is 0.0004 Ω· m, and the grounding resistance of the power frequency grounding resistance test is 1.02 Ω.

(3) The soft graphite grounding electrode and soft grounding module have been tested multiple times in different geological conditions, proving that they can fully meet the requirements of grounding resistance and achieve good results.

2、 Structural characteristics of soft graphite grounding electrode

1. It does not degrade in soil and has a service life of over 50 years;

2. Non toxic, pollution-free, safe and environmentally friendly;

3. Adapting to various environments, the product is lightweight, easy to construct, and can meet the different needs of customers.

3、 The technical characteristics and characteristic parameters of soft graphite grounding electrode have an average resistivity of 0.0004 Ω· m and a power frequency grounding resistance of 1.02.

4、 The production and testing standards for soft graphite grounding electrodes are based on the GB/T21698-2008 standard. Soft graphite grounding electrodes are woven from 1000 parts of expanded graphite, 140-170 parts of glass fiber, and 20-60 parts of materials that improve tensile strength and conductivity.

5、 Compared with other traditional grounding electrodes, the use of soft graphite grounding electrodes in combination with soft graphite grounding modules reduces electrical resistivity and outperforms other traditional grounding electrodes. It saves 50% of excavation volume, reduces construction intensity, shortens construction time, and reduces green compensation costs by 50%. Its service life is over 50 years, with no secondary maintenance costs. In mountainous areas with inconvenient transportation, there is no need to transport bulky equipment such as welding machines. The installation process is simplified and can be connected by lap joints, greatly shortening the installation and construction time. Overall, it has high cost-effectiveness and significant advantages in all aspects. Therefore, soft graphite grounding electrodes are the best choice in high soil resistivity grounding projects.
