Mechanical load of cables
12.2 Mechanical load of cables
According to DIN VDE 0298, specific values for strain relief and bend radii may not be undershot dur-
ing the routing of heavy current cables and data cables. The standard also describes the permitted
types of fastenings of cables using clips and their strain reliefs.
12.3 Separation of different services
DIN VDE 0100-520 states that cables of different voltage classes may only be installed together in
a routing system if all the cables have protective insulation against the highest occurring voltage.
Separating webs can be used to separate the different cables, as can the guarantee of a sufficient
spacing.
12.4 Fire protection
The avoidance of fires, particularly in public buildings, is the main aim of fire protection. The spread of
fire and particularly of smoke into other fire sections must be prevented with all the means available for
a sufficiently long period of time. This provides the opportunity to take escape, rescue and extinguish-
ing measures.
Fire protection measures should be taken on duct systems connecting/crossing fire sections, escape
and rescue routes. The directives for cable systems (M)LAR system floors (M)SysBör regulate this in
more detail.
The main causes for a fire on heavy current cables are:
– Incomplete short circuits or ground faults, e.g. on mechanically or thermally damaged cables
– Incorrect electrical connections, e.g. through a loose contact
– Heat build-ups
