It is well known that the copper layer thickness of copper clad steel earth rod
is 0.127mm, 0.254mm, 0.33mm, 0.50mm and other specifications. The thicker the copper layer, the higher the price, many customers may feel that the lower the price of the thin copper layer grounding rod is OK, but the thicker the copper layer of the copper clad steel earth rod, the better resistance reduction. So when choosing the copper clad steel grounding rod, we should not only pay attention to the price, but also look at the thickness and quality of the copper layer of the copper clad steel earth rod. Only high quality copper clad steel earth rod products can bring ideal drag reduction effect.
The diameter, length and copper layer of copper clad steel earth rod can be customized according to customers' needs. It is also explained that the copper layer of the copper clad steel earth rod is also related to the resistance reduction effect of the copper clad steel earth rod when grounding. Many customers buy copper-clad steel earth rods with the price of copper-clad steel grounding rods as the dominant factor. If the copper clad steel earth rod is grounded, we recommend that you choose the copper clad steel grounding rod standard to purchase. When the copper layer of the copper clad steel earth rod reaches 0.254 mm, the copper clad steel earth rod bends 180 degrees without falling off or cracking, and the copper layer is firm and has strong corrosion resistance. The thread is processed by special wire mould. The copper layer is uniform and firm, and the greatest feature of the grounding rod is that both ends are covered with copper layer, and the whole rod is not exposed to iron, which greatly enhances the service life of the grounding rod.
That is to say, if you buy cheap copper clad steel earth rod with copper layer less than 0.254 mm, the performance of the copper clad steel grounding rod you buy may be greatly reduced. The copper layer on the surface of the copper clad steel grounding rod (average thickness is more than 0.25mm), has strong corrosion resistance, long service life (more than 30 years), reduces the overhaul labor intensity, and has better electrical performance. The surface copper material has excellent electrical conductivity, which makes its resistance far lower than that of conventional material. The copper clad steel earth rod with 0.254 mm copper layer is safe and reliable when connected. Using special connection pipe or exothermic welding, the joint is firm and stable.
