HEX makes the components of an earthing system: earth rods (also called grounding rods) in copper bonded, solid copper, mechanically copper clad and stainless steel, with couplers, driving studs and heads; polymer and concrete earth pit chambers; earth rod seals; and earth bars for earth pits. HEX also offers ground enhancing chemical compounds, and the catalogue lists ESE air terminals for lightning protection. The 250 micron copper bonded rods in 14.2 mm and 17.2 mm are compliant with IEC 62561-2, and the catalogue marks the UL listed sizes. For the clamps, bonds, tapes and holders that connect the system, see the accessories.
An earth pit chamber is the housing over the point where the conductor connects to the earth rod. HEX makes square and round chambers in polymer (3 to 5 ton load-bearing capacity) and concrete (3 to 5 ton).
What are copper bonded and solid copper earth rods?
Copper bonded rods are low carbon steel rods bonded with 99.9% pure electrolytic copper (250 micron or 25 micron). Solid copper rods are 99.9% pure electrolytic copper throughout, and suit aggressive soil such as soil with a high salt content.
What is the ground enhancing chemical compound used for?
The compounds are engineered to lower the resistivity of the soil around the earth electrode. They can be used on their own or blended, and HEX recommends a blend from the site’s soil resistivity and the equipment to be earthed.
Which rods and clamps are UL listed?
The catalogue marks the UL listed copper bonded, solid copper and stainless steel rod sizes, and UL listed ground clamps. UL listed copper bonded rods have a minimum copper bonding of 254 microns under UL 467.
