• Plaster may discoloured chemical reactions. The distances between these down-conductors
should not smaller than 1/3 the distances in
Table 2.22.

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.
The following should noted this regard:
• Plaster can damaged heat expansion.
Fasteners
Fasteners for conductors must tested according to
IEC 62561-4.
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.
If, for architectural reasons, the down-conductors can-
not routed the surface, then they should in-
stalled gaps the masonry, for example. equal importance
is the correct mounting the appropriate holder, with
the matching mounting material for different wall and
ceiling materials. The artificial aging metallic fasteners
is tested the artificial weathering plastic hold-
ers, and mechanical load tests are also carried out.) with dimensions
larger than the quadruple down-conductor distance
should equipped with additional internal down-con-
ductors with spacing far possible.
General information: non-isolated downconductors/
connection internal supports
Building structures with large area (such typical
industrial plants, trade fair halls, etc.
Here, only the fastener tested.
• Conductors with PVC jacketing avoid such stains
