Graphene Grounding Electrode Description:
The core of graphene alloy grounding device adopts φ195 round steel is made into a 1.2M long rod core using a CNC machine, and various metal materials such as graphene, silver powder, aluminum powder, zinc powder, and copper powder are used. Made through the process of infiltration hot plating, the combination of various metal materials and steel is a combination of metal molecules, without electrochemical corrosion of the primary battery effect, with good conductivity, fast discharge speed, lightning resistance, and no need for any anti-corrosion treatment. lts anti-corrosion mechanical life can reach 40 years.
Graphene Grounding Electrode Advantages:
1. Anti Corrosion Performance:
According to the standard clause GB/T21698-2008, the inspection method for the corrosion rate test of 69 grounding electrodes after grounding. The measured corrosion rate is 0.0003mm/year, far below the inspection requirement of 0.03mm/year. According to the national standard GB6458-86 Salt Spray Test, the product did not show significant corrosion after 500 hours of face testing, meeting the testing requirements. The service life of other products on the market is far lower than that of graphite thin grounding products
2. Conductivity
According to the DL/T1312-2013 testing standard, tests were conducted on resistivity, relative conductivity, and short-term withstand current. The measured DC resistivity was 403pcm, relative conductivity was42.8%, and short-term withstand current was 1724KA/s.
