Grounding and Earthing Products
Grounding or Earthing, as the word suggests, is the connection of any object to earth, and this is the most important safety procedure from electrical shocks and fires. Alltec provides the following range to enhance effectiveness of grounding systems:
- TerraDyne Electrolytic Grounding System is a multipurpose grounding system. It has been designed to provide long term protection from lightning, electrical transients, static discharges, electro-magnetic interference and other electrical hazards. The system may be used for virtually any application where the protection of machinery, electronics, and personnel is important.
- TerraFill Ground Enhancement Material provides a simple method to substantially lower the earth resistance of grounding systems. When used with copper grounding equipment, this advanced backfill lowers the contact resistance to earth by up to 63%. It is permanent, effective, and environmentally friendly. It performs in all soil conditions, requires no maintenance, and will not dissolve or decay over time.
- TerraWeld Exothermic Welding System provides ultimate permanent molecular bonding and is the universally preferred method for making copper-to-copper and copper-to-steel electrical connections. It is a simple, cost-effective, everlasting connection using a high-temperature exothermic reaction that does not require an outside heat or power source. TerraWeld works when others won't!
- TerraBar Bus Bar Series is manufactured by Alltec and offers a wide variety of hole patterns and sizes. Plated versions are available for use in corrosive environments, and these products are UL listed. Alltec purchases its materials in high volumes, ensuring customers value pricing and fast turnaround time for custom bus bar configurations.
The three-tier Alltec
Protection Pyramid begins with the installation of a stable, low resistance, and low impedance grounding system to bond all electrically conductive surfaces together. As the first tier of Alltec's
Protection Pyramid, harmful electrical currents are safely redirected to earth and away from power, telephone lines, or data equipment with these grounding products. Beginning with the project's initial conception, and continuing throughout its life cycle, Alltec remains dedicated to providing the best possible solution to each project's specific needs.
Electrolytic Grounding Systems
TerraDyne
TerraDyne EGS is a multipurpose grounding system. It has been designed to provide long term protection from lightning, electrical transients, static discharges, electro-magnetic interference and other electrical hazards. The system may be used for virtually any application where the protection of machinery, electronics, and personnel is important. Read more »
Exothermic Welding
TerraWeld
The TerraWeld Exothermic Welding System provides the ultimate in permanent molecular bonding. The process of exothermic welding, in which no outside source of heat or power is required, is the universally preferred method of making electrical connections of copper-to-copper or copper-to-steel.

Low-Resistivity Grounding Backfill
TerraFill
TerraFill is an easily applied product which produces lower steady state and stable grounding impedance. It produces lower surge impedance resulting in faster transient dissipation. Manufactured from environmentally safe and stable products, TerraFill has an excellent shelf life and long term storage has no performance effects. Read more »
Grounding Bars
TerraBar
Terrabar copper buss bars available in a full line of hole patterns and sizes along with all of the associated mounting hardware and insulators. Also offered is the option for tin or nickel plating and the capability of having the ground leads exothermically welded to it. Read more »
