In a grounding system, the ground electrode provides the physical connection to the earth and is the instrument used to dissipate current into it. There are two main types of electrodes.
"Natural"? electrodes are intrinsic to the facility and include metal underground water pipe, the metal frame of the building (if effectively grounded), and reinforcing bar in concrete foundations.
"Made"? electrodes are installed specifically to improve the performance of the grounding system and include wire meshes, metallic plates, buried copper conductor and rods or pipe driven into the ground.
The ground rod is the most widely used grounding electrode. CAHE offers a complete line of rods and accessories to meet the industry needs.
Features
Copper-bonded Ground Rods
- Resist corrosion better than galvanized rods allowing for approximately 30-year service life in most soils
- State of the art manufacturing process helps ensure uniform plating thickness
- Minimum tensile strength of 80,000 psi and straightness tolerance of .010" per linear foot
- Exceed the requirements of ANSI®/UL® 467, CSA, and ANSI/NEMA® GR-1
- Manufactured of high strength 1018 cold drawn steel
- The CAHE preferred ground rod
Compression Couplers for Pointed Rods
- For use when coupling pointed rods
Sectional Copper-bonded Ground Rods
- For use when it is necessary to deep-drive rods
- Cold-rolled threads - stronger than cut threads
Threaded Couplers for Sectional Rods
- For use when coupling sectional rods
Drive Studs for Sectional Rods
- Screws into threaded coupler while rod is being driven
