![]() The Chem-Rod can reduce these risks more effectively than other ground rods by providing the most efficient earth interface. The damage caused by a single lightning strike or stray current can cost millions in equipment losses, downtime, and personnel injury. This larger surface area helps create the low-impedance connection required to safely channel high-frequency lightning currents to earth. In these events, electrodes with more surface area have less impedance.Ī copper Chem-Rod has about four times more surface area than a traditional ground rod. High-frequency transient events like lightning force current flow to the surface of an object. Optimized pigtail: The 2-foot long, 4/0 AWG stranded pigtail is exothermically welded to the body of the Chem-Rod.Easy refills: Every Chem-Rod comes with a standard removable cap and access cover for easy maintenance of the ground salt charge. ![]() Increasing the amount of GAF can decrease the overall system resistance, increasing the system efficiency. Soil augmentation: Ground Augmentation Fill (GAF) is a combination of organic soil materials which optimize the conductivity of the soil around the Chem-Rod.The salts continually increase the soil’s conductivity, further reducing impedance and resistance. Electrolytic salts: In the presence of moisture, these salts dissolve and seep out of leach holes along the electrode.Large surface area: The wider 25/8 inch diameter provides a larger surface area for a better connection to the earth.The Chem-Rod uses advanced engineering to achieve a consistent, low-impedance electrical connection with the earth, even in unfavorable and varying ground conditions (like permafrost). The Chem-Rod is an ultra-efficient grounding electrode designed to provide the optimal low-resistance, low-impedance interface with earth. The earth/electrode interface is further enhanced by conductive backfill and electrolytic salts, ensuring a consistent path to ground.Įngineered to meet applicable design and safety standards, the Chem-Rod is uniquely suited for both general grounding and as the foundation of a complete lightning protection system. The Chem-Rod solves problems found with conventional ground rods by requiring less real estate and fewer electrodes to meet specified resistance.Įach Chem-Rod creates an optimal electrical connection to earth with a large conductive surface. But conventional ground rods are typically insufficient for industrial uses where target resistance can be less than 1 ohm. Low-MaintenanceĪn efficient grounding system is critical to personnel safety and uninterrupted operations. Service life of over 30 years with no increase in resistance when properly maintained. EconomicalĬost-effective for reaching target resistance at large sites or where space is limited. ![]() Maintains low resistance in changing temperature and soil conditions. Lower resistance/impedance achieved with fewer rods. ![]()
