Product Q&A

Q:What are the characteristics and applications of copper-clad steel grounding rods?

They feature independent monitoring, digital communication, and database management. Suitable for humid, saline, acidic soils, and chemical environments. Used in power plants, substations, communication stations, airports, and railways.

Q:Why are copper plated grounding rods used for lightning protection?

They provide a safe pathway for electrical energy dissipation, ensure a stable grounding reference point, and prevent stray voltage. Made of high-strength steel coated with 99.9% pure copper for durability and conductivity.

Q:What are the benefits of pure copper grounding materials compared to copper plated ones?

Pure copper offers 8x better conductivity and 10x corrosion resistance with a 40+ year lifespan. Copper plated materials balance cost and mechanical strength using a steel core, suitable for most engineering scenarios.

Q:How is heat release welding performed?

Prepare materials (powder, mold, igniter), polish surfaces, bake and clamp the mold, add powder, ignite, wait 10 seconds, inspect quality, and clean. Wear safety gear and apply anti-corrosion coating.

Q:What is the service life of the grounding rod?

Copper-clad steel lasts over 30 years. Pure copper lasts over 40 years. Galvanized steel lasts 10-15 years. Lifespan depends on soil corrosiveness and environmental conditions.
