The role of copper bonded earthing rods is to provide an effective earthing system for electrical installations. The performance of these rods is influenced by some key factors that further decide conductivity, durability, and efficiency.

1. Soil Resistivity
The resistivity of the soil affects the performance of earthing rods. For low resistivity, soils like moist clay assist conductivity, whereas extremely high resistivity such as in dry sand or rocky terrains would not help in achieving good efficiency.

2. Copper Coating Thickness
Thicker copper coating provides better corrosion resistance and increases the life of earthing rods. Better quality rods normally have at least 250 micron thickness of uniform copper coating.

3. Installation Depth
Deeper installations would allow better contact with earth and thus would be expected to exhibit lower grounding resistance. As far as earthing performance is concerned, a minimum depth of usefully 2-3 m is advisable.

4. Environment
Harsh conditions where high moisture, acidic soils, or industrial pollutants are present cause greater corrosion and thus affect conductivity. Coating or chemical treatments need to be applied in such cases.

5. Connection & Maintenance
Proper clamping, joint connections, and scheduled maintenance ensure that loose fittings do not occur and that grounding continues to be an efficient means.
