Advantages Of A Chemical Grounding Rod

An efficient grounding system is critical to personnel safety and uninterrupted operations but conventional ground rods are typically insufficient for industrial uses where target resistance can be less than 1 ohm.

The Chem-Rod solves problems found with conventional ground rods by requiring less real estate and fewer electrodes to meet specified resistance.


Do you know the advantages of installing Chem grounding rod manufactured by LEC?

  • 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 which 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 grounding rod.
  • Improved Safety: The Chem-Rod can reduce these risks more effectively than other ground rods by providing the most efficient earth interface. In addition, it meets or exceeds relevant design codes and safety standards for protection of personnel, property, and sensitive equipment.
  • Outperforming competition: A recent NEGRP study tested 15 different types of grounding electrodes including the horizontal Chem-Rod and vertical Chem-Rod. The test included 8 years of analysis at five U.S. sites with results verifying that the Chem-Rod consistently provided the lowest resistance of all models tested.

How does a grounding system work?

Complete grounding system carries unexpected electrical charges safely to the ground without harming any other source. For example, a lightning strike can easily send an extra voltage of electricity to different electrical components thereby damaging them. With a grounding system in place, this damage can be easily avoided.


Efficient grounding systems reduce the risk of electrical arcing and fires. The chemical grounding rod by LEC improves reliability for many applications, including:

  • Lightning Protection System
  • Prevention of accidents caused by static charge and stray currents
  • Protection of central communications, electronics, and AC power systems
  • Meeting grounding safety requirements for electrical substations
  • Ground fault neutralization
  • Safeguarding critical instrumentation and process-control equipment

Our grounding rod has proven to be the best and most economical grounding solution.
