7 Installation, handling and maintenance
7.1 For your safety
-
Take note of the assembly instructions before starting assembly, installation
or other work on the BTS busbar trunking system.
7.1.1 Intended use
The unibar H busbar system is used to set up fixed, enclosed busbar trunking
systems, BTS
-
for energy transport between the transformer station and the low voltage
main distribution board (LVMD)
-
for energy transport between low voltage main distribution boards (LVMD)
-
for energy transport between low voltage main distribution boards (LVMD)
and low voltage sub distribution boards (LVSD)
-
for energy distribution by extending as a line distributor / switchgear
combination system by fitting tap-off units (only for busbar elements with
protection type IP55 / IP65)
Design variants
The unibar H busbar system is available in various IP protection type versions:
-
unibar H with protection type IP55 / IP65
-
unibar H with protection type IP68 (cast resin system)
The busbar elements for the busbar system are available in different versions
-
with inner aluminium conductors and steel housing,
-
with inner copper conductors and steel housing,
-
each in 4-pole versions with N, L1, L2, L3 conductors and the steel housing
serving as the PE protective conductor,
-
each in 5-pole versions with N, L1, L2, L3 conductors and the steel housing
serving as the PE protective conductor and an additional internal conductor
serving as PE2,
-
aluminium housings are available on request.
Busbar elements with different geometric shapes and a different position of the N
conductor are available.
The busbar system can be routed horizontally or vertically in installation position.
The inner conductors can be installed in the upright or flat position. When
installed flat and horizontally, the N conductor is positioned at the bottom.
The unibar H busbar system with protection type IP68 (cast resin system) is used
exclusively for transporting electrical energy over busbar trunking runs without
tap-off units.
