• Conductors with PVC jacketing avoid such stains.
• Plaster may discoloured chemical reactions.
All the internal supports and all internal partition walls
with conductive parts, such steel reinforcement
rods, which not fulfil the conditions for the separa-
tion distance, should connected the air-termina-
tion system and the earthing system suitable points.
General information: non-isolated downconductors/
connection internal supports
Building structures with large area (such typical
industrial plants, trade fair halls, etc.
Fasteners
Fasteners for conductors must tested according to
IEC 62561-4.Building with glass facade
Down-conductors: special considerations
If not possible arrange down-conductors on
one side side part the building, then these
down-conductors should installed the other
sides.
If, for architectural reasons, the down-conductors can-
not routed the surface, then they should in-
stalled gaps the masonry, for example.
