The service life of ion grounding electrodes should be understood in two situations: the main body life and the ion body life. The main lifespan refers to the lifespan of the rod and connecting components loaded with ion materials, that is, how many years they will not be corroded and the product connection will not detach on its own when buried in the ground. At present, the main body uses copper ion grounding rods, which are generally calculated based on the lifespan of copper. In normal environments, it is not a problem to use them for 30-50 years.

Plasma is actually a material loaded into the body that can release ions, usually in the form of a powder. This part is like consumables in a printer, constantly consumed During its interaction with water molecules, with soil erosion and continuous dilution of its own components, the function of releasing ions completely disappears. Its lifespan is far less than that of the main body. According to the statistics of ion grounding rods on the market, the longest lifespan of the ion is no more than 5 years. In other words, after 5 years, the ion grounding rod you purchase now will become a traditional one. Of course, it still serves as a grounding function, but loses the ability to release ions, resulting in a reduced grounding effect.

So is there a way to solve the problem of ion disappearance and ensure its long-term release of ions? Many manufacturers have come up with many methods, among which the most commonly used method is to use a reserved manhole cover for the ion grounding rod during installation. That is, when burying the ion grounding rod, it is not completely buried in the soil, but exposes an end cover. After several years, when the ion is consumed, the ion is artificially added to prolong its working time. However, this approach has many shortcomings. Firstly, several years later, there were significant personnel changes, and the company or personnel responsible for the project were already missing due to the difficulty of tracking and maintaining them; Secondly, due to the reserved end cap and the fact that the main body of the ion grounding rod is made of precious metal, the anti-theft problem cannot be solved. Of course, there is another improved solution, which is to change the pore size of the ion grounding hole and use an external catalyst induction mechanism. On the one hand, it reduces the release rate of the ion, while the external induction mechanism ensures the amount of ion release, thereby extending the lifespan of the entire ion to about 8 years. Currently, various manufacturers are continuously researching and improving the service life of ion grounding electrodes.
