The Importance Of Corrosion Resistance Of Copper-clad Grounding Rods To Grounding Systems

Most copper rod for earthing steels adopt a structure that combines a copper layer with a steel core. This design allows the outer copper layer to play a protective role when the steel is buried in the soil for a long time and exposed to various corrosive factors (such as humidity, pH changes, and microbial activity), unlike the performance of a single bare metal. When the 8ft copper ground rod copper layer comes into contact with soil, it will naturally form an oxide film. This passivation phenomenon helps to slow down the further oxidation process and improve the material's long-term performance.

The corrosion mechanism in underground environments is influenced by various factors, including the soil's chemical composition, electrolyte concentration, and current flow. 333 The thickness and uniformity of the copper layer directly affect the surface stability of copper bonded rod under complex soil conditions, while the metallurgical bonding process relates to the interface integrity between the copper layer and the steel core, thus affecting copper rod for earthing price's corrosion resistance.
