Copper Bonded Electrode is many folds better than GI Earthing because of their lower resistance, anti-corrosive nature, longer life, better stability, and other reasons to count all. There are lots of company that manufactures Pure Copper/Copper Bonded/GI/Pipe-in-Pipe.
Copper Bonded Earthing Electrodes manufactured from high tensile low carbon steel by molecularly bonding 99.9% pure electrolytic copper, their earth rods conform to BS 4360 grade 43A. Each rod is treated with Benzol triazole derivatives to prevent oxidation of copper bonding. The threads are formed by roll threading process which ensures strength and maintains the molecularly bonded copper along the full length of the threads. The rods can be deep driven manually or by using power hammer.
The choice between GI (Galvanized Iron) Earthing Electrode and Copper Bonded Electrode largely depends on the specific requirements of the application. Both types of electrodes are used to create an effective earthling system in electrical installations, but they have different properties and advantages.
GI Earthing Electrodes are cost-effective and offer good corrosion resistance, making them a popular choice in many applications. They are easy to install and maintain, and can handle high fault currents. However, they have a relatively short lifespan and may require periodic replacement.
Copper Bonded Electrodes are made by coating a layer of copper over a steel core. They offer excellent conductivity and corrosion resistance, and have a longer lifespan than GI electrodes. They are particularly useful in environments with high soil resistivity, where they can provide a low-resistance path to ground. However, they are more expensive than GI electrodes and require careful handling during installation to avoid damaging the copper layer.
In summary, if cost is a major concern, GI Earthing Electrodes may be the better choice, while Copper Bonded Electrodes may be preferred for applications where high conductivity, durability, and corrosion resistance are essential. Ultimately, it is best to consult with a qualified electrical engineer to determine the most appropriate type of electrode for a specific application.
Both GI (Galvanized Iron) earthing electrodes and copper-bonded electrodes have their own advantages and applications, and the choice between them depends on various factors. Let's compare them:
In summary, if you require a highly conductive and durable grounding system in environments with high moisture or corrosive conditions, copper-bonded electrodes are recommended. However, if budget is a concern and the soil resistivity is moderate, GI electrodes can be a viable option.
Pure copper electrodes are preferable to GI earthing electrodes because of their superior conductivity. Hope this helps!

Copper Bonded electrode is the best as it has durability, anticorrosive and improved properties.

GI Earthing electrodes are cost-effective and corrosion resistant but they do have a shorter life span.
Both GI (Galvanized Iron) earthing electrodes and copper bonded electrodes have their own advantages and disadvantages.
GI Earthing Electrode:
1. Cost-effective: GI electrodes are generally cheaper compared to copper bonded electrodes.
2. Suitable for normal soil conditions: GI electrodes are suitable for most soil conditions, except in areas with highly corrosive soil.
3. Durable: GI electrodes have a long lifespan and can withstand harsh weather conditions.
1. Corrosion: GI electrodes are prone to corrosion over time, especially in areas with highly corrosive soil.
2. High resistance: GI electrodes have higher resistance compared to copper bonded electrodes, which can affect the overall effectiveness of the earthing system.
Copper Bonded Electrode:
1. Low resistance: Copper bonded electrodes offer lower resistance, providing better electrical conductivity and reducing the chances of voltage fluctuations.
2. Corrosion resistance: The copper bonding on the electrode prevents corrosion, making it suitable for all types of soil conditions.
3. Longer lifespan: Copper bonded electrodes have a longer lifespan compared to GI electrodes.
1. Higher cost: Copper bonded electrodes are generally more expensive compared to GI electrodes.
2. Vulnerable to theft: Copper has a higher resale value, which makes copper bonded electrodes more susceptible to theft.
Ultimately, the choice between GI and copper bonded electrodes depends on factors such as the soil conditions, budget, and specific requirements of the earthing system. It is recommended to consult with a professional electrical engineer or earthing specialist to determine the best option for a specific application.
Copper earthing is where copper, which is known to be a good electrode due to its high conductivity, is used. The copper pipes are installed in the earth pit which can maintain the resistivity in high resistivity soil or rock conditions.
G.I earthing uses mild steel pipes with Galvanized Iron coating to complete the earthing system. Steel is also a very good conductor of electricity and allows any dangerous electricity to flow to the ground, taking the danger away from you.
The myth talks about the two materials, Copper used in Copper earthing and Galvanized Iron used in G.I. earthing. It is also believed due to this myth that copper earthing must be used in locations that demand less resistivity like factories.
Hence, another myth that sprouts through this myth is that the application of G.I. and Copper earthing differs. G.I. earthing is preferred to be used in households while is used copper earthing is usually installed in factories and industrial spaces due to very low resistivity requirements.
The Resistivity Formula
Now that we know that one is pipe earthing and the other is plate earthing. Here are two formulas for calculating the resistivity of both. Have a look:
Resistance formula for pipe earthing
(R) = (100r/2πL) X loge (4L/d)
L= Length of Pipe/Rod in cm
d=Diameter of Pipe/Rod in cm
r = Resistivity of Soil Ohm-meter.
Conclusion: Myth vs Truth
If you notice these formulas, you can see the two major factors that come into play are; resistivity of the soil and the physical dimensions of the electrode, not the material resistivity.
Hence, it does matter if the location is household or industrial, the type of soil and the size and number of the electrode will define whether the resistivity achieved is high or low.
The copper electrode used in copper earthing may result in longevity of the earthing and hence it may be preferred, but not because of its resistivity.
copper bonded electrode is considered best as it has properties such as anti-corrosion, durability,etc
