  • 本站编辑:杭州晨诺机械科技有限公司发布日期:2018-10-08 13:52 浏览次数:
铜包钢接地棒的好坏判断除了钢芯之外,就是铜镀层了,铜镀层影响到铜包钢接地棒很多方面的性能,下面晨诺机械整理了一下为大家解答。
 
Copper clad steel grounding rod is good or bad judgment in addition to the steel core, copper coating, copper clad steel grounding rod affects many aspects of performance, the following Chennuo electrical finishing for everyone to answer.
 
铜包钢接地棒铜镀层厚度可以用电子厚度测微仪在各点按规定的次数丈量,厚度至少要达到0.250mm此厚度保证了镀铜后制作的螺纹底部全部被铜覆盖。
 
The thickness of copper coating on copper clad steel grounding rod can be measured by electronic thickness micrometer at each point according to the prescribed number of times. The thickness should reach at least 0.250mm. This thickness ensures that the bottom of the thread made after copper plating is covered with copper.
 
 
接地棒铜镀层厚度最薄为0.250mm保证在地下理论使用寿命达到30年。
 
The copper coating thickness of the grounding rod is thinnest to 0.250mm, which ensures that the service life of the underground theory reaches 30 years.
 
 
 
镀层的可塑性:
 
The plasticity of coating:
 
 
 
将铜包钢接地棒弯曲180°后进行测试,不得出现裂缝和剥落,铜镀层的粘合度—当接地棒打入地下时,应检测镀层是否趋向分离。
 
The copper clad steel grounding rod is bent 180 degrees and tested. Cracks and spalling are not allowed. The adhesion of the copper coating - when the grounding rod penetrates the ground, it should be checked whether the coating tends to separate.
 
 
 
具体方法为:把待测的接地棒夹在虎口钳之间,钳口之间的距离等于棒的直径减去1.2mm当棒被挤压时,虎口钳会切下与之接触的棒的镀层,而表面的其余局部镀层不会剥落,这样的镀层可以保证接地棒在镀铜后可加上螺纹。
 
The specific method is: clamp the grounding rod between the pliers, the distance between the pliers is equal to the diameter of the rod minus 1.2 mm. When the rod is extruded, the pliers will cut off the coating of the contact rod, and the rest of the coating on the surface will not peel off.
