Routing cables
When filling the fire protection duct system with cables, we recommend
laying them and not pulling them in.
If it is not possible to lay the cables, then you should observe the follow-
ing information when pulling in the cables:
• Use suitable pulling apparatus to pull the cables into the duct system
in a straight direction. Use an appropriate aid at the start of the cable
(e.g. cable hose, drawbar eye).
• Use suitable steering rollers to pull the cables round bends and
T branch pieces, in order to avoid damage to the duct system and
cable insulation.
• Never pull cables over sharp edges to exclude the risk of insulation
errors.
• Comply with the tensile forces and minimum bend radii specified by
the cable manufacturer.
