A Copper Bonded Earthing Rod (Unthreaded) is a solid steel core electrode with a permanent molecularly bonded copper coating, designed to provide a low-resistance path to earth in grounding and lightning protection systems. Unlike threaded rods, the unthreaded type has a smooth surface, making it ideal for applications where couplers are not required, or a single-length rod is sufficient.

• Material: High tensile strength low-carbon steel core.

• Copper Bonding: Electrolytic copper molecularly bonded to steel (thickness typically 250–300 microns).

• Design: Smooth, unthreaded surface with a pointed driving end.

• Function: Dissipates fault current or lightning surge safely into the ground.

• Corrosion Resistance: Copper coating resists rust and extends service life.

• Electrical Earthing – Domestic, commercial, and industrial installations.

• Lightning Protection Systems – As grounding electrodes for down conductors.

• Telecommunication Towers – Prevents equipment damage from voltage surges.

• Renewable Energy Systems – Solar and wind farm grounding.

• Solid Single-Length Rods – For standard installations.

• Heavy-Duty Copper Bonding – Thicker copper layer for aggressive soil environments.

• Special Tip Designs – Hardened steel tips for rocky terrain.

1. Tools & Materials Required

• Copper Bonded Earthing Rod (Unthreaded)

• Driving head / driving stud (to protect rod tip during installation)

• Sledgehammer or mechanical rod driver (jackhammer with adaptor)

• Earth conductor and approved earthing clamp

• Measuring tape

• Earth resistance tester

• PPE (safety helmet, gloves, boots, eye protection)

2. Site Preparation

1. Location Selection – Choose a location away from underground services, fuel lines, and building foundations.

2. Soil Check – Prefer moist soil for better conductivity; avoid rocky, dry areas unless necessary.

3. Mark Installation Point – Clearly mark the spot where the rod will be driven.

3. Installation Procedure

1. Position the Rod – Place the rod vertically over the chosen spot.

2. Attach Driving Head – Fit the driving head onto the top of the rod to prevent mushrooming or deformation during hammering.

3. Drive the Rod –

   • Manual Method: Strike the driving head with a sledgehammer until the rod is fully driven.

   • Mechanical Method: Use a powered rod driver for faster penetration in hard soils.

4. Achieve Target Depth – Drive the rod to the required depth (commonly 2–3 meters) or until desired resistance is achieved.

5. Remove Driving Head – Once at depth, remove the driving head carefully.

4. Electrical Connection

1. Clean Rod Surface – Remove any dirt or debris from the rod where the clamp will be fitted.

2. Attach Earthing Clamp – Use a copper or bimetallic clamp to connect the earth conductor to the rod securely.

3. Tighten Connection – Ensure firm mechanical grip and good electrical contact.

5. Testing

• Measure earth resistance using a 3-point or 4-point earth tester.

• Target resistance should be within local standards (often < 1–5 ohms).

• Record test results for compliance documentation.

6. Safety Notes

• Always confirm there are no buried utilities before driving.

• Use PPE to avoid injuries from flying debris or vibration.

• In rocky terrain, pre-drill a pilot hole if necessary.

• High corrosion resistance and long service life.

• Superior conductivity due to copper surface.

• Strong steel core allows deep driving without bending.

• No threads — ideal for single-section installations and cost efficiency.
