Multiple ground rods with Copper Coated for anti thunder device 

Technical Specification:                                                                          

1) The purity of the copper which used as cladding is more than 99.95%.

2) The steel core is low carbon steel which the carbon content is about 0.15%.

3) The copper bonded ground rod will be capable of being through 90 at a maximum radius

    of 100mm with no copper fracture and with no ill effect on the bond between the steel and

    the copper cladding.

4) Good in anticorrosion that usage-life is more than 50 years, constant low resistance and good plasticity

    which has the characteristics of the pure copper.

5) The ground rod is fully covered with copper cladding without any cracks, holes, cavities etc. 

    Preventing exposure of the steel core to soil and moisture, so as to form a good corrosion

     resistance.

Characteristics of Copper bonded earthing system:

1. The advanced automatic electroplating production lines and four dimensional continuous speed electroplating processes ensure the uniform coating and stable performance.
 
2.“Accelerate corrosion experiments” are carried by China authority department with different soil types, and the service life is proven more than 40 years.
 
3. The factory lab is equipped with advanced analytical instruments, e.g. atomic absorption spectrophotometer, UV-Vis spectrophotometer, conductivity meter, COD meter, PH meter etc. analyzed instruments. It also includes Metallurgical Microscopy, universal testing machine, Salt Spray test chamber, and thickness tester etc. These instruments can analyze and test dozens of technical parameters during the plating production process, which ensures the reliable electroplating process.
