Gem Rod

Technical Survey of GEM-Rode

GEM-Rod Grounding System maintains the most efficient and stable low resistance, low impedance grounding regardless of the installation site’s environmental situation such as geological condition, moisture, or seasonal changes. It is a new generation grounding system devised to stably manage various info-communication facilities and other electric equipments. It uses a “high conductance environment-friendly grounding rod” that contains electrolytes for grounding. It shows high grounding performance even in rocky and sand soil areas where installation is difficult, and thus ensures better grounding environment than any other grounding methods.

High Performance
Low grounding resistance (below 1 ohms) & low grounding impedance
Stable quality regardless of climate, weather or soil conditions
Ensures minimum resistance value with minimum area and minimum cost
Providing of control environment to maintain optimum quality

Grounding Enhancement Grounding Method maximizes the contact area with the earth to realize minimum grounding resistance, and it also maintains optimal grounding system through use of environmentfriendly GEM powder. It also has low grounding impedance, which allows it to suppress GPR and discharge lighting and AC fault current quickly to the ground.
