ROUND CONTUCTOR RD8/ALU-T

Rotary conductor RD 8-ALU-T 50mm˛ The grounding system is part of external lightning protection that conducts the lightning current to the ground 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 < 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 the potential equalization system! 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 at a distance of up to 2 km can generate dangerous overvoltages in the building's electrical equipment. OBO provides all necessary products for implementing reliable lightning protection: lightning rods, surge protectors, potential equalization and grounding accessories.
