NO. 236E-THE THOMPSON "ENHANCER"
REDUCES THE RESISTIVITY OF THE SOIL SURROUNDING THE GROUND ROD. THIS GREATLY
INCREASES THE EFFICIENCY OF THE GROUNDING SYSTEM. REDUCTION OF GROUND
RESISTIVITY IS ESPECIALLY IMPORTANT IN AREAS OF POOR SOIL CONDUCTIVITY
AND/OR SHALLOW DEPTH. UNDER THESE CONDITIONS, REDUCTIONS OF GROUND ELECTRODE
RESISTANCE OF UP TO 80% OR MORE MAY BE EXPECTED. THE "ENHANCER" CAN
ALSO BE USED AS A STAND-ALONE GROUND ELECTRODE WHERE SHALLOW SOIL PRECLUDES
DRIVING GROUND RODS. THE ENHANCER IS MANUFACTURED FROM FOUR INCH
COPPER PIPE. THIS PROVIDES TWICE THE SURFACE CONTACT AREA PER FOOT COMPARED
TO ALTERNATIVE PRODUCTS. THIS DEVICE ALSO OFFERS SIGNIFICANT INSTALLATION
COST SAVINGS SINCE NO MECHANIZED AUGERING IS REQUIRED.
THE TOP CAP IS AT GRADE LEVEL AND IS REMOVABLE FOR INSPECTION, GROUND TESTING, AND REPLENISHMENT OF THE "LOW-OHM," HIGH CONDUCTIVITY FILL MATERIAL. HOLES IN THE CAP ALLOW RAINFALL OR WATER FROM SPRINKLER SYSTEMS TO COLLECT IN THE RESERVOIR AND EACH INTO THE SOIL AS A HIGHLY CONDUCTIVE ELECTROLYTE. UNDER ABNORMALLY DRY CONDITIONS, ADDITIONAL WATER MAY BE POURED INTO THE RESERVOIR IF THE LOWEST POSSIBLE GROUND RESISTANCE VALUES MUST BE MAINTAINED. THIS WILL USUALLY BE UNNECESSARY AS PREVIOUSLY LEACHED "LOW-OHM" MATERIAL IN THE SOIL WILL GREATLY INCREASE ITS CONDUCTIVITY EVEN UNDER DRY CONDITIONS. NON-TOXIC, ENVIRONMENTALLY FRIENDLY MAGNESIUM SULFATE IS USED AS THE ACTIVE ELEMENT. FIFTEEN POUNDS OF "LOW-OHM" ENHANCEMENT MATERIAL ARE INCLUDED WITH EACH "ENHANCER." NO. 237-"LOW-OHM," HIGH CONDUCTIVITY EARTH ENHANCEMENT FILL FOR USE WITH NO. 263E "ENHANCER" UNIT. 100LB. BAG. |
