Reliable Grounding Performance for Various Soil Conditions

1. Stable Grounding in Complex Environments

Saint Ni Lightning Protection Copper Bonded Grounding Rod Threaded Type is developed for projects where stable grounding resistance is difficult to achieve. The threaded extension design allows multiple rods to be connected vertically, helping the grounding electrode reach deeper soil layers with lower resistance.

It is suitable for challenging environments such as dry areas, rocky soil, mountainous regions, and locations with limited construction space, providing a practical solution for improving grounding effectiveness.

2. Long-Term Corrosion Resistance Underground

The grounding rod adopts a low-carbon steel core combined with a high-purity electrolytic copper layer. This copper bonded structure combines the mechanical strength of steel with the corrosion resistance of copper.

The dense copper layer helps protect the rod from moisture, salt, acidic soil, and alkaline soil conditions, ensuring reliable underground performance and reducing maintenance requirements during long-term operation.

Durable Copper Bonded Structure with High Performance

1. Strong Steel Core for Installation Reliability

The internal steel core provides excellent strength and impact resistance, allowing the grounding rod to maintain structural stability during installation in hard soil or gravel layers.

This design reduces the risk of bending or deformation and supports reliable deep grounding applications.

2. Efficient Conductivity for Lightning Protection

The high-purity copper outer layer provides excellent electrical conductivity and supports fast current transmission during lightning strikes or electrical faults.

Compared with traditional galvanized steel grounding electrodes, copper bonded grounding rods offer better conductivity and corrosion protection, making them suitable for long-term grounding systems.

Threaded Design for Faster Installation

1. Easy Extension Without Welding

The threaded connection structure allows multiple grounding rods to be connected through matching copper bonded couplers without welding equipment.

This simplifies installation procedures, improves construction efficiency, and provides greater flexibility for different grounding depths.

2. Cost-Effective Solution for Grounding Projects

The easy connection method helps reduce installation difficulty and labor requirements. By minimizing excavation work and simplifying construction processes, the threaded copper bonded grounding rod provides an economical solution for small and medium-sized grounding projects.

Applications of Copper Bonded Grounding Rod Threaded Type

1. Power and Electrical Infrastructure

This grounding electrode is widely used in substations, power distribution systems, transmission towers, and other electrical facilities where stable grounding performance is required to protect equipment and improve operational safety.

2. Communication, Industrial, and Renewable Energy Projects

The product is suitable for communication towers, data centers, factories, solar farms, and wind power projects. Its corrosion-resistant structure and flexible installation design allow reliable performance in outdoor and long-term infrastructure applications.

Engineering Application Case

1. Project Name

35kV Mountain Substation Deep Well Grounding Project

2. Project Background and Geological Challenges

This 35kV substation is located on a hillside, with the site primarily consisting of hard rock strata. The strata have high resistivity, and the surface dry sand and gravel have poor conductivity. Furthermore, the excavable space on the hillside is limited; using a large-area shallow grounding grid would significantly increase land acquisition and earthwork construction costs.

3. Reasons for Initial Solution Failure

The initial shallow grounding rod laying scheme consistently failed to meet grounding resistance standards, resulting in failure to pass power acceptance. In addition, the hot-dip galvanized grounding rods had insufficient corrosion resistance, developing severe corrosion after only a few years of operation, requiring frequent excavation and rectification, leading to high maintenance costs.

4. Core Design Objectives

The project clearly requires that the grounding resistance be stably controlled within 4Ω, the grounding system's design life be 30 years, and subsequent maintenance costs be minimized.

5. Optimized Technical Approach

To address the challenges of high-resistivity rock formations and confined site conditions, threaded copper-clad steel grounding rods were used as the primary material for deep-well vertical grounding, forming a complete ring-shaped grounding network with matching copper-clad steel flat bars. Vertical drilling using an impact drilling rig penetrated the high-resistivity rock and dry gravel layers, reaching the moist, low-resistivity soil layer underground, achieving efficient resistance reduction.

The entire system utilizes molecular metallurgical electrolytic copper-clad steel of the same material, eliminating electrolytic corrosion between dissimilar metals. Anti-corrosion conductive grease is applied to the threaded joints, forming a double-sealed barrier to effectively isolate the soil from corrosive media.

6. Comprehensive Benefits

This solution eliminates the need for large-scale excavation of shallow trenches, reducing earthwork and resistance-reducing agent consumption by 50% compared to traditional methods, significantly compressing construction costs and time. The copper layer and steel core are molecularly bonded, resistant to salt and alkali corrosion. Over ten years of operation, annual grounding resistance measurements have consistently remained below 4Ω, with no rust requiring repair, fully meeting the project requirements for 30-year long-term use and low maintenance investment.
