Universal power distribution<br />
The BD2 system (up to 1250 A) supplies power<br />
to medium-size loads in buildings and all<br />
sectors of industry. Pre-assembled tap-off units<br />
with the most diverse equipment enable universal<br />
use. Two standard frame sizes covering all<br />
current ratings simplify stock keeping and<br />
planning.<br />
Siemens offers modular ancillary equipment units for indication, control and monitoring<br />
of the flow of power through busbar trunking systems. These units are equipped with bus<br />
interfaces, control circuit devices and power meters.<br />
The LX busbar trunking system is the perfect equipment for multi-storey buildings where<br />
large quantities of power need to be transported, uninfluenced by the mounting position<br />
of the system.<br />
High availability in production<br />
The louvred LD busbar trunking system, up to<br />
5000 A, is the system for transporting current in<br />
production lines with a large energy requirement,<br />
such as in the automotive industry. A<br />
separate PE bar enables the assured response<br />
of the protective device over long conducting<br />
paths. The high short-circuit resistance permits<br />
protection by medium-voltage circuit-breakers<br />
for the conveyance of power between the<br />
transformer and the main infeed. Tap-off units<br />
up to 1250 A can be plugged in without causing<br />
any problems.<br />
Flexible power distribution for multi-storey<br />
buildings<br />
The LX sandwich-style system, up to 6300 A, is<br />
used where large quantities of power need to be<br />
transported, uninfluenced by the mounting position<br />
of the system. Be it for radio broadcasting<br />
stations, computer centers or Internet providers<br />
– conductor configurations with an insulated<br />
PE/ground conductor and double neutral conductor<br />
cross-section guarantee an interferencefree<br />
power supply. Tap-off units up to 1250 A<br />
are available as standard.<br />
Safe power conveyance for petrochemicals<br />
The encapsulated LR system (up to 6300 A) is<br />
extremely resistant to external interference<br />
thanks to its high degree of protection. This<br />
ensures safe and reliable transport of power<br />
even in rough weather or in highly dust and dirt<br />
and corrosion polluted industrial environments.<br />
Typical applications of this system is the petrochemical<br />
industry, waste incinerators and power<br />
stations.<br />
