Grounding Rods provide an easy path for electricity to flow to earth should any problem occur like a lightning strike, power surge, short circuit, etc. If properly installed, grounding rods can prevent fire, shock, danger to human lives, and damage to electrical and electronic equipment.
In order to perform its protective function for buildings and other objects, grounding rod must have a robust path to a good ground. This means that multiple welded heavy copper ground conductors must be used. This lowers the electrical resistance and inductance along the path while providing the mechanical strength to withstand the huge magnetic forces created by the high lightning strike’s peak current.
In addition, the entire lightning protection system must be connected to an extensive network of copper grounding rods and a conductive steel building framework. The grounding system is distributed over a wide surface area in order to create a low-resistance electrical path to Earth's ground. In general, the lower the grounding system resistance, the better will be the performance of the lightning protection system.
Benefits of copper earthing rods by LEC:
- Conductivity
- Ductility and malleability
- Flexibility
- Reliability
- Durability
- Commercial use
- Corrosion resistant
- Consistent
- Low maintenance
Our patented grounding rod is called Chem-Rod. It uses advanced engineering to achieve a consistent, low-impedance electrical connection with the earth, even in unfavourable and varying ground conditions (like permafrost).
- Large surface area: The wider 25/8 inch diameter provides a larger surface area for a better connection to the earth.
- Electrolytic salts: In the presence of moisture, these salts dissolve and seep out of leach holes along the electrode. The salts continually increase the soil’s conductivity, further reducing impedance and resistance.
- Soil augmentation: Ground Augmentation Fill (GAF) is a combination of organic soil materials that optimize the conductivity of the soil around the Chem-Rod. Increasing the amount of GAF can decrease the overall system resistance, increasing the system efficiency.
- Easy refills: Every Chem-Rod comes with a standard removable cap and access cover for easy maintenance of the ground salt charge.
- Optimized pigtail: The 2-foot long, 4/0 AWG stranded pigtail is exothermically welded to the body of the Chem-Rod.
