Lyncole XPT products for Latina America are for high performance grounding applications. Where space is small, soil resistivity is high, the required resistance-to-ground is low (10 Ohms or less) and the application is of high or strategic value (such as airports, military installations, heavy industry) there are no alternatives to electrolytic tubes. Lyncole is the owner of the original patent. The guarantee for our electrolytic tubes is 30-40 years. Tubes are available in both horizontal (for installation in a trench) as well as vertical. Standard length is 3m; we have other lengths as well as available in sections that can be combined to reach dozens of meters of depth.
