Level 3 Lightning Protection for Communication Power Systems

This Recommendation provides guidance on protecting indoor distribution systems for mobile communication in large-scale buildings from lightning and safety risks. It emphasizes compliance with standards like IEC 62305-3, IEC 62305-4, IEC 60364 series, and ITU-T K. 21 for effective. What are lightning protection levels (LPL)? The different Lightning Protection Levels (LPL), only refer to the type I arrester and its impulse current 10/350 µs. This classification is based on the level of lightning protection required. The current edition is IEC. The motto in the picture – BLITZSCHUTZ GIBT SICHERHEIT (“LIGHTNING PROTECTION PROVIDES SAFETY”) – is as relevant today as it ever was, with external lightning protection still providing valuable passive fire protec-tion in the event of a direct lightning strike.
