About ACE Chemrod Earthing Electrode 3 TOSHA has developed its earthing system based on a unique technology known as “Artificial Concept of Earthing by Chemical Rod” (ACE CHEMROD EARTHING ELECTRODE). This concept was developed for Earthing after a consistent R&D and is being Manufactured & Marketed as "ACE Chemrod Earthing Electrode". This concept has revolutionarised the earthing world. www.toshainternational.com September 17, 2018

ACE Chemrod Earthing Electrode Over the years, we have developed an unrivaled expertise in the design, manufacturing, and installation of our revolutionary, state-of-the art corrosion free, eco friendly grounding system ideal for almost all type of soil conditions and environments. www.toshainternational.com September 17, 2018

ACE Chemrod Installation Procedure www.toshainternational.com September 17, 2018

Design and Fabrication On the Basis of Resistance As per IS 3043-1987 and IEEE Green Book The resistance of pipe or electrode is given by where – ρ = soil resistivity (in Ω. m) L = length of pipe/rod (in cm) D = diameter of pipe/rod (in cm) R= 100ρ/2πL X log 4L/D www.toshainternational.com September 17, 2018

Design and Fabrication For example- Take rod/pipe of dimensions length=2500mm dia = 50mm By the above formula to achieve desired value less than 2 ohms will require 32 number of rods/pipes electrode, which is neither possible practically nor commercially. Where as resistance less than 2 ohms can be easily obtained by using one or two ACE Chemrod Earthing Electrodes. www.toshainternational.com September 17, 2018

Design and Fabrication On the basis of Length :- As per IS 3043 & IEEE Green Book It is depicted in fig. resistance Vs length that the resistance diminished slowly at depth greater than 2.4 m in soil, which justifies the length of ACE Chemrod Earthing Electrode. Being concentric pipe technology the overall effective length improves the performance equivalent to multiple rods. www.toshainternational.com September 17, 2018

Design and Fabrication On the basis of artificial treatment of soil As per IS 3043: Multiple rods in large numbers may sometimes fail to produce low resistance to earth. To reduce soil resistivity it is necessary to dissolve moisture contained in soil. This Concept helped us in developing an earthing compound, we call it as Tosha Earthing compound, which has all the qualities of an ideal backfill material for an earthing system. Special absorption capability. Can absorb available moisture in vicinity. Provides low earth resistance. Enhances surrounding soil conductivity. Prolonged Durability and performance. Provides Cathodic Protection. www.toshainternational.com September 17, 2018

Design and Fabrication 12 On the basis of Life Of electrode: As per IS 3043 The average rate of decay of ACE Chemrod Earthing Electrode (2500mmx3mmx50mm) in no case exceeds 0.5% per year. As per this data ACE Chemrod Earthing Electrode (2500mmx3mmx50mm) will loose half of its strength in no less than 35 years, which helps it in retaining results for longer period of time. www.toshainternational.com September 17, 2018

Design and Fabrication Tosha Earthing Compound (T.E.C) contains highly conductive chemical where every particle of T.E.C. works as a separate electrode. The highly conductive chemical increases the overall conductive zone for maximum current dissipation to get stable reference point. Increased current dissipation zone reduces current density which inturn provides low soil resistivity. Seasonal change brings high variation in ground water level providing more fluctuation in ohmic value. ACE Chemrod Earthing Electrode is installed up to 2.5 meters beneath the surface, practically remains unaffected from water level variation and maintains constant result for longer period. Conventional Earthing requires continuous maintenance and needs to be changed frequently in every 3 to 4 years. Where ACE Chemrod Earthing Electrode is a Fit and Forget Formula which practically needs no change. www.toshainternational.com September 17, 2018

Design and Fabrication 14 This is a maintenance free Earthing, no need of extra water pouring at regular interval as in conventional Earthing, because it retains the moisture for longer period. Can be installed indoors or outdoors and in almost all soil condition. For existing or new facilities, requires less space & time. Adequate galvanization makes it Corrosion free. The composition of highely conductive chemicals are non toxic thereby making T.E.C eco friendly. www.toshainternational.com September 17, 2018

Summary All the above arguments undoubtedly proves and solidifies the fact that ACE Chemrod Earthing Electrode is manifold advantageous, reliable, eco friendly, easily installable, maintenance and corrosion free etc. www.toshainternational.com September 17, 2018
