Copper-bonded rods are grounding electrodes used to provide an effective path to dissipate electrical energy into the earth. They consist of a core made of either steel or copper-coated steel, which is then surrounded by a layer of high conductivity copper. This construction combines the strength of steel with the conductivity of copper, offering both durability and efficient grounding capability.

The primary function of copper-bonded rods is to create a low impedance path for the dissipation of electrical currents, particularly in the event of a fault or lightning strike. They are commonly used in various applications such as telecommunication towers, power distribution systems, industrial facilities, and residential buildings.

The copper layer on the rod ensures high conductivity, which is essential for effective grounding. It helps to reduce resistance and impedance, allowing for the efficient dissipation of electrical energy into the surrounding soil. This is crucial for maintaining electrical safety and preventing damage to equipment and structures.

When installing copper-bonded rods, it's essential to consider factors such as soil resistivity, rod length, and spacing to ensure optimal performance. Proper installation and maintenance are key to ensuring the effectiveness of the grounding system over time.
