They are one of the best choices for Earth Electrodes. They can be used in areas with high corrosion or in applications where an exceptionally long life is needed. They are also used in installations with high fault currents. These Solid Copper Rods are manufactured from Solid Copper bars and are then processed to enable jointing. These Solid Copper Rods however are not suitable for deep driving into the ground because of the possibility of bending and are additionally significantly more expensive than the other Rod options.
They are made using an electroplating process where a layer of Copper is deposited on a steel core. Copper Bonded products offer an advantage over copper-clad products because they are molecularly bonded with the steel core and will thus not slip or tear when they are driven into the ground. Copper Bonded Rods are also significantly more cost-effective than Solid Copper Rods while still providing corrosion resistance and low electrical resistance. Additionally, the steel core makes these Copper Bonded Rods more favourable to be driven into the ground.
Thus, Copper Bonded Rods provide high tensile strength using low carbon steel with molecularly bonded 99.9% pure electrolytic copper. This makes Copper Bonded Rods the most economically efficient and popular choice for Earth Rods around the world. Axis has more than 25 years of experience manufacturing and selling Copper Bonded Rods to utilities and other customers in more than 80 countries. Contact us to find out more about our products!
Stainless Steel Earth Rods offer functionality akin to our Solid Copper Rods but come with the added advantage of being more anodic. This feature makes them a preferred choice in environments where different types of metals are buried close to one another, minimizing the risk of galvanic corrosion. Though they tend to be on the pricier side compared to other options, their unique anti-corrosion properties make them a valuable choice for specialized applications.
Galvanized Steel Earth Rods are constructed from high-strength, low-carbon steel and undergo a hot-dip galvanizing process. While they are the most cost-effective option available, it’s important to note that they offer limited corrosion resistance and possess lower electrical conductivity and current-carrying abilities.
Earth Rods and their accessories provide high fault current capacity for LV, MV and HV substations, towers and other distribution applications. They can be used for both overhead and underground networks to achieve optimum earthing for distribution and transmission.
Earth Rods are one of the most popular Earth Electrodes used globally because:
