ROD 1801/KL3

Potential equalization
When lightning strikes a building protected by external lightning protection, large potential differences can arise between the building and installed systems (electrical, telecommunications cables), leading to dangerous fires and damage. Nearby lightning strikes generate strong magnetic fields that can damage electrical equipment. But even lightning strikes up to 2 km away can create dangerous overvoltages in the building's electrical equipment. OBO provides all the necessary products for implementing reliable lightning protection: lightning rods, surge protectors, potential equalization and grounding accessories.
