Copper clad steel grounding rods, good conductivity, high mechanical strength, good corrosion resistance.
Main technology parameter
1. Copper layer the thin thickness Greater than or equal to 0.3mm
2. Tersile strength intensity greater than or equal to 600N/mm²
3. Flathess error less than or equal to 1mm/m
4. Copper layer plasticity: When the grounding rod bend 30° , Bending angle domestic and foreign no crack phenomenon.
5. Copper layer combined: To come over adhesion test. In addition to inside caliper jaw. Occlusion Now spalling copper layer, The rest of copper steel combination good does not appear is stripped phenomenon.
