CHEMICAL GROUNDING ( CHEM-ROD) Brand : HITACHI

CHEM - ROD Low - Impedance Chemical Grounding Electrode EFFICIENT : Lower resistance/ impedance achieved with fewer rods CONSISTENT : Maintains low resistance in changing temperature an soil condition ECONOMICAL : Cost-effective for reaching target resistance at large sites or where space is limited RELIABLE : Service life of over 30 years with no increase in resistance when properly maintained LOW - MAINTENANCE : Designed for easy inspection and refill The Chem-Rod solves problems found with conventional ground rods by requiring less real estate and fewer electrodes to meet specified resistance. Each Chem-Rod creates an optimal electrical connection to earth with a large conductive surface. The earth/ electrode interface is further enhanced by conductive backfill and electrolytic salts, ensuring a consistent path to ground. Engineered to meet applicable design and safety standards, the Chem-Rod is uniquely suited for both general grounding and as the foundation of a complete lightning protection system. APPLICATIONS Efficient grounding systems reduce the risk of electrical arcing and fires. The Chem-Rod improves reliability for many applications, including: • Lightning protection systems • Prevention of accidents caused by static charge and stray currents • Protection of central communications, electronics, and AC power systems • Meeting grounding safety requirements for electrical substations • Ground fault neutralization • Safeguarding critical instrumentation and process control equipment INDUSTRIES : • Petrochemical, LNG, and nuclear facilities • Data centers, telecoms, and roadcasters • Process control and automation • Corrections, hospitals, and 911 centers • Government, military, and defense installations • T& D operations, substations, and wind turbines INSTALLATION The Chem-Rod achieves superior results wherever it can be buried in the earth: indoors or outdoors, in sandy soil or permafrost, even in or beneath concrete slabs. The vertical Chem-Rod is installed in an augured hole. Where augering deep holes is impractical, such as in rocky soil, the horizontal configuration is installed in a shallow trench. Both configurations come filled with electrolytic salts and, as a final step, are backfilled with a mixture of GAF and native soil to achieve the maximum electrical connection to earth.
