Brief：. So that it can promote slow release and resistance reduction outside the conductor and make sure resistance values are http://www.chinagroundrod.com/

High carbon Ionic compound Crystal is filled inside the tube of Electrolytic Ion Grounding electrode with copper and steel on surface so as to make sure the best conducting performance and long life span . The filler inside the conductor includes special electro-ionic compound so it can absorbs water in the air and release the active electro-ionic into soils through deliquescence functions and combines with water in soil and air.
