Ground rods are made by special process, molecular bonding purity electrolytic coating of copper 99.9 % deposited over a layer of nickel onto high tensile and low carbon steel cores to ensure a perfect and even bonding between the steel and copper. Kumwell ground rods has a copper layer whose minimum thickness is 254 micron met IEC 62561-2 and UL standard cause to resistance a severe corrosion to acidic and high concession of salt environment for long lifetime up to 40 years
Copper-Bonded Ground Rod
Copper-Bonded ground rod is made by molecularly bonding pure electrolytic copper onto a low carbon, high tensile steel core with exceeding 0.254 mm (254 micron) thick. The material made of 99.9% pure electrolytic copper with high tensile steel. To ensure in safety and quality, it meets UL and IEC standard for grounding and bonding equipments.
