It is important to remember that when you select Earthing Electrodes,M.O.C.(Metal of Conductor) is play a big role. Specially for new era earthing electrode which is Known as Chemical Earthing Gel Earthing, Maintanance Free Earthing, when you are selecting it you are not selecting product, you are selecting a Solution. the quality of Gel earthing which is used to drive your valuabels, Doesit mean the diffrence between HD-HOT Dip Galvanized iron and Galvanized iron? Major diffrence will occur in Electrode's life,in HDG and NON-HDG Electrodes.Even in copper electrodes diffrence will occur in conductivity also
Recent industry research has revealed that there are many products in the market that do not provide the HD (Hot-Dip Galvanizing) which is very much affect to your earthing life and result in ohms value as well as for them to perform properly. This is a result of poor manufacturing and the use of sub-standard components to save on production costs. The quality of your HD Electrodes also mean the diffrence between a safe and long life earthing system.
Hot-Dip Galvanizing is the process of coating fabricated steel by immersing it in a bath of molten zinc. there are three fundamental steps in the hot-dip Galvanizing process;Galvanizing and inspection
