Copper Clad Steel Ground Rod

The copper layer of copper-clad steel grounding rod is strong. Copper clad steel ground rod bending 180° Copper layer does not crack, does not peel. Corrosion resistance of copper-clad steel ground rod and copper-covered steel strand. Using steel with tensile strength of up to 600N/mm2, the copper-clad steel grounding rod can reach deep underground (up to 35m) with the help of a percussion drill. Copper clad steel grounding rod is 99.9% purity of electrolytic copper molecules coated on the steel core. The copper clad steel grounding rod is made of Q235 low carbon steel and made of large reduced cold drawing process, which not only overcomes the defects of poor binding force of the casing coating method, enhances the tensile strength, and maintains toughness. The outer plating of 99.9% pure copper provides customers with copper layer thicknesses of 0.254mm, 0.33mm, 0.5mm, 1.0mm, etc. The copper clad steel grounding rod has passed ISO9001:2000 quality system certification to ensure that all parameters meet the requirements.

When the copper clad steel ground rod is driven into the ground, it should be detected whether the coating tends to separate. The specific method is: clamp the copper-clad steel ground rod to be measured between the jaws, and the distance between the jaws is equal to the diameter of the rod minus 1.2mm. When the copper-covered steel ground rod is squeezed, the vice pliers will cut the coating of the copper-covered steel ground rod in contact with it, and the rest of the surface coating will not peel off, so that the coating can ensure that the copper-covered steel ground rod can be threaded after copper plating.

The thickness of the copper coating can be measured by an electronic thickness micrometer at each point according to the specified number of times, and the thickness must be at least 0.250mm. This thickness ensures that the bottom of the thread made after copper plating is completely covered with copper. The copper coating thickness of the copper clad steel ground bar is 0.250mm, which guarantees that it can be used for 30 years underground.
