Copper coated earth rods offer installers the most economical method of achieving a low earth resistance. Each rod has a high tensile strength, low carbon steel core. 99.95% pure copper is applied electrolytically and forms a metallurgical bond between the steel core and the copper. This combination makes the rod ideal for deep driving whilst also provides lasting resistance to corrosion. The threads are formed by a cold rolling process which ensures strength and maintains the molecularly bonded copper covering along the full length of the threads. Cold-rolled threads are stronger than cut-threads. The standard copper thickness is 0.25mm. Greater copper thicknesses are also available.
銅覆鋼接地棒為最經濟的降低接地電阻的手段,接地棒由高強度的低碳鋼和99.95%的純銅組成,銅和鋼之間為分子連接,可具備很好的防腐性能和直接深埋,螺紋由滾絲機擠壓而成,可保證其強度,且保持銅層始終覆蓋在螺紋上。滾絲機擠壓的螺紋遠比車床開的螺紋強度要高。標準銅層厚度為0.25mm,更大銅層厚度可選。
