Nano Carbon Grounding Round Wire

Unlike grounding materials that rely mainly on a single protective layer, this construction combines the mechanical strength and conductivity of galvanized steel with the corrosion-resistant properties of the nano-carbon coating. The circular cross-section also provides uniform mechanical stress distribution, making the wire easier to route around equipment, grounding grids, and irregular installation areas.

The Nano Carbon Grounding Round Wire can be supplied in 6 m straight lengths or large coils for different project requirements. It is suitable for horizontal grounding conductors, equipment grounding branches, lightning protection systems, and equipotential grounding networks. Saint Ni Lightning Protection supports customized dimensions and project-based supply for renewable energy, power, chemical, and infrastructure projects.

Electrical and Structural Design

Galvanized Steel Conductive Core

The solid galvanized steel core serves as the main current-carrying path. Lightning currents, fault currents, and other grounding currents are transmitted through the steel core rather than relying on the outer coating as the primary conductor.

The galvanized steel substrate also provides good tensile strength and resistance to bending, compression, and mechanical impact, making it suitable for underground installation and large-scale grounding grid construction.

Nano-Carbon Protective Layer

The outer nano-carbon coating forms a protective barrier between the galvanized steel core and the surrounding soil. It helps reduce direct exposure to acidic, alkaline, saline, and chloride-containing environments.

The coating is manufactured with strong adhesion to the substrate and is designed to remain stable during normal handling, bending, underground installation, and soil backfilling. Its conductive characteristics also contribute to the electrical interface between the grounding conductor and surrounding soil.

Circular Cross-Section

The round profile provides more flexible routing than rigid flat conductors in certain grounding layouts. It can be positioned around equipment foundations, connected to vertical grounding electrodes, and arranged along radial branch lines.

For large projects, coil supply can reduce the number of intermediate joints and simplify material handling, while 6 m straight sections are suitable for projects requiring standardized lengths.

Key Product Benefits

Stable Current Transmission

The galvanized steel core provides the primary electrical conduction path for lightning and fault currents. Its solid construction supports stable current transmission throughout the grounding network.

Protection for Corrosive Soil

The combination of galvanized steel and a nano-carbon outer coating provides two levels of protection. This makes the material suitable for soil environments containing salt, moisture, chloride ions, or chemical contaminants.

Flexible Installation

The Nano Carbon Grounding Round Wire can be routed around equipment and connected to different grounding components. It supports exothermic welding and grounding clamps, allowing contractors to select connection methods according to project requirements.

Reduced Grounding Grid Joints

Large-coil supply can reduce the number of connection points compared with short individual sections. Fewer joints can simplify installation and reduce potential weak points within extensive grounding networks.

Project-Oriented Supply

Saint Ni Lightning Protection can provide different diameters, lengths, packaging methods, and customized cutting according to project drawings. Complete test documentation can also be supplied for project inspection and acceptance.

Project Application Case

42 MW Energy Storage Project in Medina, Saudi Arabia

Located in a saline-alkali desert environment, the 42 MW energy storage project required a grounding system with long-term corrosion resistance and stable grounding performance.

Saint Ni Lightning Protection supplied Φ12 mm Nano Carbon Grounding Round Wire for equipment radial grounding, combined with nano-carbon flat strips, angle steel, and grounding rods to form the complete grounding network.

After three years of operation, inspections showed no obvious coating peeling or steel-core corrosion. Grounding resistance remained stable during different seasons. The solution reduced grounding material costs by 39% and shortened construction time by approximately 30%, while successfully passing the project's lightning protection acceptance inspection.

Chemical and Industrial Sites

Suitable for industrial facilities where soil may contain acidic, alkaline, saline, or chemically contaminated media and conventional grounding materials may require frequent maintenance.

Installation Requirements

Connection Treatment

Before connection, the nano-carbon coating should be removed from the designated connection area to expose the galvanized steel substrate. Exothermic welding or suitable grounding clamps can then be used according to the project design.

For welded connections, remove welding slag after the joint has cooled and apply suitable corrosion-protection treatment to the exposed area where required.

Trench Backfilling

Grounding trenches should preferably be backfilled with screened fine soil. Stones, construction debris, and sharp objects should be removed before backfilling to prevent mechanical damage to the protective coating.

Backfilling should be performed in layers and compacted according to the project construction specification.

Installation Inspection

After installation, grounding resistance should be tested by an appropriate method specified by the project design or applicable local standard. Test results should be recorded as part of the concealed-work inspection documentation.
