EARTHING STRAP 927/2

Grounding clamp 2x2.5-25mm˛, Ø17-114mm
When a direct lightning strike hits 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 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.

Internal lightning protection protects the building from dangerous lightning discharge currents and sparking. Dangerous sparking can occur primarily when the lightning discharge current creates large potential differences between the building's metal parts, such as pipes, cable trays, etc., and the potential equalization system components. All electrical and information technology equipment must be well protected, as a direct connection is established between the external lightning protection and the building's electrical installations via the grounding and potential equalization system. To prevent building damage, a lightning and surge protection system according to the EN 62305 (IEC 62305) standard is required.
