As technology changed, it brought a significant shift in the earthing philosophy. Initially, Chemical Earthing was introduced. Chemical earthing has changed the way earthing system was viewed. Now we have have a range range of rods or electrod electrodes es made made from from various various highly highly conductive materials which are connected to the equipments with strips and other accessories in the chemical grounding process. Special compounds to fill in the earth-pit, around the electrode to conditioning the soil with eco friendly minerals, along with the new types of earth Rods and earth Electrodes, ensure that these earthing systems provide you an incredibly longer working life of 2030 years with high conductive and low resistance path. These are reliable and require minimal to

Underground Earthing Electrode The construction details of the Chemical Earthing Electrode are as bellow: There is a solid conductor (highly galvanized), enclosed inside another highly galvanized Chemical Earthing Electrode. The space in between is filled with anticorrosive & conductive compound. The electrode composite system which is firmly packed / welded & sealed with sealant & is ready to use. The basic purpose of the mineral mineral filling compound compound is to resistance resistance and to create a low resistance resistance zone surrounding the electrode uniform environment so that the electrode output is constant.
Use of of salt & charcoal charcoal is eliminated eliminated in the method method of effective effective earthling earthling & instead a specially developed, developed, natural eco friendly material material with improved improved properties properties is used. This is non corrosive, has capacity to absorb & retain moisture from the surrounding. Being non soluble in water, it stays at the place and in not washed out by the rain water/underground water. This mineral filling compound is highly conductive. •
