As a leading manufacturer based in Wuxi, China, Wuxi Yansheng Technology Co., Ltd. proudly presents our Standard Diameter Solid Copper High Conductivity Copper Ground Rod, designed specifically for power grid earthing systems. With a factory spanning 1,000–3,000 square meters and a dedicated team of 101–200 employees, we have been delivering reliable grounding solutions since 2017. Our annual export value of US$50–100 million underscores our global reach and commitment to quality. This ground rod is crafted from high-purity solid copper, ensuring exceptional electrical conductivity and long-term durability—essential for safe and efficient earthing in electrical infrastructure.
Our copper ground rods are engineered to meet the rigorous demands of modern power grids. The standard diameter design allows for easy installation with common clamps and connectors, while the solid copper construction eliminates the risk of corrosion and mechanical failure often associated with copper-clad or steel alternatives. Whether used in substations, transmission towers, or industrial facilities, this product provides a stable, low-resistance path to earth, protecting equipment and personnel from electrical faults and lightning strikes.
Key Features & Technical Specifications
High Purity Solid Copper: 99.9% copper content ensures maximum conductivity and minimal resistance.
Standard Diameter Options: Available in 14mm, 16mm, 18mm, 20mm, and other common sizes—customizable upon request.
Superior Corrosion Resistance: Solid copper naturally resists rust and chemical attack, extending service life in harsh environments.
High Mechanical Strength: Tensile strength ≥ 200 MPa, suitable for driving into various soil types without bending.
Easy Installation: Threaded top accepts standard driving studs and connectors; smooth surface reduces friction during driving.
Versatile Applications: Ideal for power grid earthing, substation grounding, lightning protection, telecommunications, and industrial plants.

Frequently Asked Questions (FAQ)
What is the standard diameter for this ground rod?
Common diameters include 14mm, 16mm, 18mm, and 20mm. Custom diameters are available upon request to match your specific needs.How does solid copper compare to copper-clad steel rods?
Solid copper offers higher conductivity (99% IACS vs. 30-40% for clad) and superior corrosion resistance. It is a one-time investment with no risk of cladding peeling or rusting.Can this rod be used in rocky or hard soil?
Yes, the high tensile strength (≥200 MPa) allows it to be driven with standard driving tools. For extremely hard conditions, we recommend pre-drilling or using a driving head.What certifications do your products have?
Our factory is ISO9001, ISO14000, OHSAS18001, SA8000, TL900 certified, among others. We can provide compliance documentation upon request.What is the typical lead time for an order?
Lead time depends on quantity and customization. Standard sizes are usually shipped within 15-20 days after order confirmation. Bulk or custom orders may take 25-30 days.Do you offer packaging for export?
Yes, we provide sturdy wooden crates, pallets, or bundles with waterproof wrapping to ensure safe transit. Packaging can be customized per your requirements.Can I get a sample before placing a bulk order?
Absolutely. We offer samples for evaluation. Please contact our sales team for sample availability and shipping costs.How do I install this ground rod?
Installation is typically done by driving the rod vertically into the ground using a hammer or mechanical driver. A threaded top allows attachment of a driving stud. For deep installations, multiple rods can be coupled with threaded connectors.
