is the correct mounting the appropriate holder, with
the matching mounting material for different wall and
ceiling materials.
General information: non-isolated downconductors/
connection internal supports
Building structures with large area (such typical
industrial plants, trade fair halls, etc.
• 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.
The following should noted this regard:
• Plaster can damaged heat expansion.
If, for architectural reasons, the down-conductors can-
not routed the surface, then they should in-
stalled gaps the masonry, for example.
Here, only the fastener tested.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. The artificial aging metallic fasteners
is tested the artificial weathering plastic hold-
ers, and mechanical load tests are also carried out.22.
Fasteners
Fasteners for conductors must tested according to
IEC 62561-4. The distances between these down-conductors
should not smaller than 1/3 the distances in
Table 2.
• Conductors with PVC jacketing avoid such stains.) with dimensions
larger than the quadruple down-conductor distance
should equipped with additional internal down-con-
ductors with spacing far possible
