Nearby lightning strikes generate strong magnetic fields that can damage electrical equipment. But even lightning strikes up to 2 km away can generate dangerous overvoltages in the building's electrical equipment. OBO provides all necessary products for reliable lightning protection: lightning arresters, surge protective devices, potential equalization and grounding accessories.
