Медь Таможенный стали Земля Род

Leiying’s Earth rods are made by molecularly bonding process 99.9%purity electrolytic copper onto a low carbon steel cores to ensure a perfect bonding between the steel and copper in accordance with national and international standards such as UL467 and BS7430. The copper layer whose minimum thickness is 254 microns. Standard size diameter being the most popular used 1/2”, 5/8” ,3/4”.Our Earth rodswith high in protection against natural corrosion and electrochemical reaction when rooted deeply in ground. Earth rods and grind wirings are welded by leiying'sExothermic weldingpowderso that the groundsystem are protected by the copper wholly and free of maintenance. The rod length range from 4' up to 10' , Earth rods are also available in the sectional type with the same length and diameters. These sectional rods are threaded on both ends to allow rod-to-rod connection by use the coupling. It has characteristics as below 1) Thickness of the copper layer is more than 0.254mm 2) Our ground rods can be bended through a 30 or 90 or 135 degrees angle, and the rods will be no evidence of cracking or splitting of the steel or the copper cladding 3) The advantages are good tensile strength more than 580N/mm2 4) Good in anticorrosion that usage-life is more than 50 years or more, constant low resistance and good plasticity which had the characteristics of copper as well as steel Part No.diameterLengthWeightPackingLYER580414.2mm(5/8”)1200mm(4’)1.50kgs(10pcs/Bundle LYER580514.2mm(5/8”)1500mm(5’)1.88 kgsLYER580814.2mm(5/8”)2400mm(8’)3.00 kgsLYER1422514.2mm(5/8”)2500mm3.13 kgsLYER581014.2mm(5/8”)3000mm(10’)3.75 kgsLYER161516mm1500mm2.38 kgsLYER162516mm2500mm3.96 kgs(5pcs/Bundle) LYER340517.2mm(3/4”)1500mm(5’)2.75 kgs(10pcs/Bundle LYER340817.2mm(3/4”)2400mm(8’)4.39 kgs(5pcs/Bundle) LYER1722517.2mm(3/4”)2500mm4.58 kgsLYER341017.2mm(3/4”)3000mm(10’)5.49 kgsLYER201520mm1500mm3.70 kgs(10pcs/Bundle LYER202520mm2500mm6.18 kgs5pcs/Bundle LYER203020mm3000mm7.41 kgsLYER251520mm1500mm5.78 kgsLYER252525mm2500mm9.63 kgsNote:1, Diameters with dia.12.7mm, dia.14.2mm & dia.17.2mm, we can supply you earth rod with threads as UNC-2A and metric standard.
