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 corrosive environments. Used in power plants, substations, airports, railways, and high-rise buildings for lightning and anti-static grounding.

Q:What is the service life of copper-clad steel grounding rods?

Generally more than 30 years. With a thick copper layer and strong corrosion resistance, they are suitable for complex environments. Lifespan can exceed 50 years depending on conditions.

Q:What are the benefits of pure copper vs. copper-plated grounding materials?

Pure copper has 8x better conductivity and 10x better corrosion resistance but is costly and has lower mechanical strength. Copper-plated materials balance cost and performance, offering steel core strength and approaching pure copper conductivity/lifespan.

Q:What is the copper layer thickness specification?

The average thickness is greater than or equal to 0.254mm (approx. 10 mils). This thickness ensures excellent conductivity and strong corrosion resistance.

Q:What are the main advantages of this product?

1. Conductivity equivalent to pure copper due to skin effect. 2. Easy transport in bundles/shafts. 3. Soft, flexible design reduces resistance. 4. Excellent anti-corrosion with 50-year lifespan. 5. Customizable manufacturing processes.
