Difference Between Copper Bonded and Galvanized Earthing Rods
Blog Article
When establishing a good grounding system, one of the most important choices is selecting the appropriate earthing rod type. Two of the most common types are copper bonded earthing rods and galvanized earthing rods, which have gained immense popularity due to their high-performance capabilities, long lifespan, and affordability. Let's know about the differences to make the best choice.
Major Differences Between Copper Bonded and Galvanized Earthing Rods:
1. Composition of Materials:
Copper Bonded Rods:
These rods consist of a steel core having a layer of pure copper electroplated over the surface. Copper thickness is different according to application requirements.
Galvanized Rods:
These rods consist of steel having a layer of zinc coating. The zinc is a sacrificial layer that corrodes with time to safeguard the steel.
2. Corrosion Resistance:
Copper Bonded Rods:
High corrosion resistance, particularly in corrosive or acid soil conditions, with a longer service life.
Galvanized Rods:
Ideal for dry or non-corrosive soils, but corrode more quickly in wet or contaminated environments, shortening their life.
3. Electrical Conductivity:
Copper Bonded Rods:
Offer superior electrical conductivity because of the presence of copper, which facilitates efficient fault current dissipation.
Galvanized Rods:
Lower conductance than copper, which can impact earthing system performance.
4. Cost Factor:
Copper Bonded Rods:
Somewhat higher initial cost but provide better life and lower replacement expense in the long run.
Galvanized Rods:
Less costly initially but could be subject to earlier replacement because of corrosion at a greater lifetime cost.
5. Applications:
Copper Bonded Rods:
Best suited for mission-critical installations such as data centers, hospitals, power plants, and alternative energy projects.
Galvanized Rods:
Optimized for low-cost, short-term, or less demanding earthing systems.
Conclusion:
Though galvanized rods appear to be economical at first, copper bonded earthing rods offer better performance, strength, and long-term cost savings, and are the best choice for permanent and sensitive applications.
