6.2.2.3 Planning in the case of vertical busbar runs
General procedure
The following applies when considering the layout of the busbar run:
●
Recording of the determining busbar elements of the run: Feeder units, junction units and
end cap
● Calculation of the run lengths between feeder units, junction units and end cap
● Providinig feeder units with fixed points
● Dividing run lengths into sub-lengths using fixed points.
● Configuring expansion compensation
● Configuring fixing bracket per storey.
Maximum permissible sub-lengths L1
After recording the infeeds, junction units and end cap within a run, the following run layouts
can result:
●
Busbar run layout between two junction units (Case 1)
● Busbar run layout between junction unit and end cap (Case 2)
● Busbar run layout between infeed and junction unit (Case 3)
● Busbar run layout between infeed and end cap (Case 4).
Subdivision into the maximum permissible number of sub-lengths L1 then takes place.
Sub-length L1 depends on the conductor material of the busbar trunking system as well as
the purpose of use (power transmission or distribution):
Conductor material Power transmission Power distribution
1)
Cu (LXC....) L1 ≤ 40 m L1 ≤ 60 m
Al (LXA....) L1 ≤ 25 m L1 ≤ 50 m
1)
At least one tap-off unit per storey
These sub-lengths are
●
between two fixed points with expansion compensation
● between fixed point and end cap without expansion compensation.
For sub-lengths between infeed and fixed point with expansion compensation, sub-length L1
is halved.
