Excel Earthings

This UL Listed ground rod features a high-tensile, low-carbon steel core bonded with pure electrolytic copper for excellent durability and conductivity. A nickel layer seals the bond to prevent separation, and the copper coating is applied after fabrication to fully cover the steel. With a crack-resistant, 254-micron thick copper layer, it offers superior corrosion resistance and long-term performance.

  • Superior Electrical, Mechanical and Thermal Properties (IEEE 837).
  • Fast Dissipation of Fault Current.
  • No joints beneath the soil as in Plate Electrodes.
  • Good Corrosion Resistance than Cast Iron/ Hot Dip GI Electrodes
