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.
铜覆钢接地棒为最经济的降低接地电阻的手段,接地棒由高强度的低碳钢和99.95%的纯铜组成,铜和钢之间为分子连接,可具备很好的防腐性能和直接深埋,螺纹由滚丝机挤压而成,可保证其强度,且保持铜层始终覆盖在螺纹上。滚丝机挤压的螺纹远比车床开的螺纹强度要高。标准铜层厚度为0.25mm,更大铜层厚度可选。
