STRAP CONDUCTOR 303/DIN

The grounding conductor 5052 DIN grounding system is part of an external lightning protection system that conducts the lightning current to earth and distributes it there. The most important criteria for the even distribution of the lightning current without the formation of dangerous overvoltages are the shape and dimensions of the grounding electrode. Standard EN 62305-3 (IEC 62305-3) recommends as low a grounding resistance as possible <lt/> 10 ohms. The grounding system can be constructed using one of the following three systems. It is possible to connect different grounding systems together, but potential corrosion risks must be taken into account. Important guideline: Grounding systems must be connected to potential equalization!<return/><return/> When a direct lightning strike hits a building protected by an external lightning protection system, 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 at a distance of up to 2 km can generate dangerous overvoltages in the building's electrical equipment. OBO offers all necessary products for implementing reliable lightning protection: lightning rods, surge protectors, potential equalization and grounding accessories.
