Sunlight Grounding supplies premium earthing materials and lightning protection products, delivering advanced and complete electrical solutions for global infrastructure projects, receiving high reputation and competitiveness from EPC Contractors.
Grounding round conductors—also known as copper bonded steel round wire coil or copper clad steel round conductor supplied by Sunlight Grounding combines excellent electrical conductivity with superior mechanical strength and long-term corrosion resistance, which have emerged as the industry's preferred solution for large‑scale grounding grids.
Sunlight Grounding copper bonded round conductors manufactured via continuous electro‑plating process creates a permanent molecular bond between the copper layer and the steel core—guaranteeing that the copper layer will not peel, crack or separate during bending, installation or long‑term use.
Key Features and Advantages of Sunlight Grounding Copper Clad Steel Round Wire Conductors (Customized Available)

| Bondability Test | Copper layer cannot be visibly peeled from steel core under extreme clamping |
| Electrical-corrosion Performance | Resistance growth ≤50% after full cycle test; growth per step ≤15%; surface without cracks, pits or bubbling |
| Bonding Method | Continuous electro‑plating (permanent molecular bond) |
| Installation | Easier to pull through conduits and trenche |
| Connection Method | Supports compression lugs, bolted and exothermic welding |
| Applications | Long‑distance horizontal grids: Photovoltaic & Solar projects, tower grounding, solar farms, etc,... |
⚫Reduce the risk of later maintenance and maintain the reliability of the grounding grid.
⚫Meet the requirements of grounding resistance and potential difference in the grounding system when used in large-scale grounding grid.
⚫Reduce direct material cost of the connection joint by 90% and labor cost (eg: The grounding material is laid in a grounding groove with a length of 100 meters, if a single 100-meter copper bonded coil is used, only one connection joint is required, while using a copper bonded steel earth rod with a length of 6 meters, 16 joints(not including both ends) should be required).
