Why Choose Cangzhou Hongxin’s U-Bolt Ground Rod Clamp?
① Superior Conductivity & Low Resistance
– Made from 99.9% pure copper (C11000) or hot-dip galvanized steel for optimal current flow.
– Ensures < 0.25 milliohm resistance, meeting UL 467 and IEEE 80 standards.
② Corrosion-Resistant for Harsh Environments
Zinc-plated or tin-coated** for protection against moisture, salt, and chemical exposure.
– Ideal for coastal areas, industrial sites, and underground installations.
③ Secure & Vibration-Proof Design
Serrated U-bolt teeth grip the rod tightly, preventing loosening over time.
Withstands extreme weather, thermal expansion, and mechanical stress.
④ Easy Installation – No Special Tools Needed
– Simply tighten the nuts to 25 ft-lbs torque for a permanent connection.
– No welding required, reducing labor costs.
⑤ Trusted Manufacturer – Cangzhou Hongxin
Over 10+ years of experience in producing high-quality grounding clamps.
Strict ISO 9001-certified manufacturing process.
Global exports to the USA, Europe, Middle East, and Asia.
Step-by-Step Installation Guide
1. Prepare the Ground Rod & Conductor – Clean surfaces with a wire brush.
2. Position the Clamp – Slide the U-bolt around the ground rod.
3. Insert the Conductor – Place the cable between the clamp body and pressure plate.
4. Tighten the Nuts – Use a torque wrench (25 ft-lbs recommended).
5. Test the Connection – Verify resistance with a ground multimeter (< 5Ω is ideal).
Safety Tip: Always de-energize the system before installation!

Common Mistakes to Avoid
Using mismatched metals (e.g., steel clamp on copper rod → galvanic corrosion).
Overtightening nuts (can crack the clamp and reduce conductivity).
Skipping antioxidant gel (increases resistance over time).
Ignoring regular inspections (check for corrosion every 1-2 years).
