Elements of Chemical Earthing System
Chemical Earthing Rods are the “heart” of the chemical earthing system. The electrodes are made of highly conductive materials. They are buried into the pit and are surrounded by the backfill compound. The top portion of the electrodes is connected to the main system of the house or the building where the earthing system is to be installed through a down conductor. Whenever lightning strikes and there is a surge in electricity in the electrical system, the current passes through the down conductor. The chemical earthing electrodes dissipate the extra surge in current into the earth with the help of the highly conductive backfill compound. Atharva Infrastructures has its own copper bonded rods, ACTROD
ACTROD is low maintenance but an important component of an earthing system. It consists of Cu-coated electrodes with the connection plate on the top and a locking disk at the bottom to protect it from theft. The standard length of the electrode is 10' (two 5' electrodes coupled with a coupler) normally but the length of the electrode can be increased in the multiples of 5 feet by adding the couplers and the electrodes. These actrods are also available in multiples of 4 feet.
ACTROD our chemical earthing rod has an excellent life span and a very appreciable load-carrying capacity. Its composition is such that it ensures enhanced performance and a wide range of protection as per the IEEE standards. Moreover, it is made of high tensile strength steel. Its composition is such that it ensures enhanced performance and a wide range of protection. The molecular bonding of the earthing rod’s material is such that it helps to slow down bi-metallic corrosion-causing processes.
Another spectacular feature of ACTROD is that it also has an additional tinned inspection plate for the flexibility of connecting strips. These features enable ACTROD to be a highly dependable electrode, owing to its low maintainability.
So, along with SOILTREAT: our Backfill compound, ACTROD is designed in such a way, that it proves to be an eco-friendly option, mainly to the soil around it owing to the corrosion resistance it provides.
Chemical Earthing Rods/Electrodes : The ACTROD
A backfill compound acts as a filling in the pit which is dug to place the earthing electrode. The backfill compound’s purpose is to prevent the chemical earthing electrode from getting corroded and facilitate better current dissipation. It helps maintain the moisture levels in the soil around the system. Atharva Infrastructures has its own conductivity improvement material,
SOILTREAT : A Backfill Compound
, our highly conductive backfill compound, is ecologically safe and does not pollute the nutrients of the soil. Its main function is to absorb the impedance from the faulty current that occurs due to lightning. It is hydroscopic in nature and very fine in size and thus, no voids are formed in the compound. Unlike other similar compounds, it is non-corrosive in nature. Therefore, it considerably slows the process of oxidation and corrosion. Apart from these characteristics, it has a very high shelf life. Being eco-friendly in nature, it does not contain any harmful chemicals like other currently available backfill compounds.
What is Chemical Earthing?
Chemical Earthing is a process that lowers the ground rod’s resistivity (to the soil), thus making the ground-connection all-the-better and improving ground resistance by injecting conductive chemicals around a ground rod. It contains the use of a backfill compound, chemical earthing rods/electrodes, lightning arresters, and other components which form an integral part of the earthing system.
This protects structures like buildings, houses and industries from an electrical surge from lightning with the use of specific compounds and chemical earthing electrodes.
Atharva Infrastructures offers environment-friendly chemical earthing systems with cost-effective prices that help everyone afford top-notch and excellent quality protection.
Why should you choose Chemical Earthing over conventional earthing?
As the electrode is not in direct contact with soil, it offers enhanced corrosion protection
Longer life of 10-15 years as opposed to 2-5 years of conventional earthing
Better efficiency and current dissipation
Backfill compound used is anti-corrosive, environment friendly and RoHS Certified
Consistent resistance values
Requires small earthing pit
Very low maintenance required because of efficient and anti-corrosive rods
Fast Installation process
The Chemical Earthing Process
There is a highly technical process involved in the installation of a chemical earthing system. The steps involved in this installation are:
A chemical earthing pit is dug into the ground near the establishment where the earthing system is to be installed.
The earthing pit is filled with , Atharva Infrastructures’ backfill compound. Quantity of the backfill compound varies with electrode length and earthing pit depth.
, Atharva Infrastructures chemical earthing rods are inserted into the chemical earthing pit with SoilTreat surrounding it. This process of inserting the earthing electrodes into the pit is meticulous and requires highly skilled labor. Atharva Infrastructures takes care of all of these processes for an accurate earthing system installation.
The final step is establishing connection between the electrical mains and the earthing rods. The earthing rods have a plate for connecting with the electrical mains in the establishment where the earthing system is to be installed. A down conductor is used for this connection. One end of this conductor is connected to the earthing electrode and the other to the electrical mains of the establishment where the earthing installation is in progress.
