Copper Coated Steel Ground Rod Supplied by Sunlightweld is Manufactured Through a Continuous Electro-plating Process of Copper Over Steel Core, Resulting in a Permanent Molecular Bond Between The Two Materials.
Copper coated steel grounding rod also known as copper clad bonded steel earth rod can be divided into vertical and horizontal grounding electrode, with its high current-carrying ability, good conductivity, and low-cost, making Sunlightweld copper bonded steel earth rod a preferred choice for grounding projects.
Copper Coated Steel Ground Rod Specifications/Feature/Advantages(Customize Available) Supplied by Sunlight Grounding
Technical parameter of copper bonded/clad steel earth rod(IEC,UL listed)
1.Tensile strength:350-770Mpa(for vertical grounding)；60-510MPa（for horizontal grounding）
2.Copper thickness: 0.254mm-0.8mm(customized available)
3. Plasticity of copper layer: When the product is bent at 90° for three times continuously, there's no crack in the inner and outer edge copper layer.
4. Copper layer bondability
When the product is placed between the clamp or the vise jaws, the spacing is smaller than the diameter of the sample steel core(W=d-0.1), hammer the end of the sample, cut off enough copper layer, fully expose the steel core, the exfoliated copper layer is allowed at the jaws of vise, however, the remaining part of rod, exfoliated copper and steel is not allowed to be visible to the naked eye.
5. Electrical-corrosion performance
Simulated fault current releasing, after the electrical-corrosion cycle test, the final resistance value growth rate does not exceed 50% of the initial resistance value, Morever, the resistance growth rate of each test step does not exceed 15% during the testing process, And the surface of the copper bonded ground rod sample is completed, without cracks, pits, bubbling defects after the test.
Performance testing and matching requirements
In terms of copper coated steel product application technology, by analyzing IEEE837, IEC62561-2, UL467 and other standards, Sunlight experimental center is equipped with test equipments for all testing, including mechanical testing ,electrical testing, corrosion testing ,ect., for product development and production quality control.
