Busbar Trunking Systems in Action

Busbar trunking systems in the low-voltge range perform the safe and reliable transmission and distribution of electrical power from transformer via main distribution board and sub-distribution board right to the load. Siemens busbar trunking systems are the complete and efficient answer in this area:• The CD system • The BD01 system for 40 A to 160 A • The BD2 system for 160 A to 1250 A The BD 01 system is quick to install and ideally suited for use in workshops and • The PEC system for 800 A to 6000 A trade premises, as here, at a photo- • The LD system for 1100 A to 5000 A • The LX system for 800 A to 6300 A Alle these systems are 'Type-tested LV switch-gear assemblies' (TTA) to IEC 60 439-1 and -2. This ensures that they offer a standard of safety and reliability that meets the particularly high performance expectations of automated pro-duction and for building services provision.
Performance characteristics:• Clear network structure• Unproblematic retrofitting in the event of load • Low operating costs due to uninterrupted ser- • Simple planning and installation The ideal system for production lines needing a great deal of power is the LD system up to 5000 A. Room-covering systems for lighting installa-
tions and small loads
The CD system (up to 40 A) allows you to supply
lighting installations covering the whole expan-
se of, say, furniture showrooms, supermarkets
or greenhouses with power, and also provides
the means to easily fix them in position.
Due to its pleasing appearance, the equipment
is well suited for use in sales rooms visited by
the public. On the other hand, its high degree of
protection, to IP54, allows the CD system to be
used even in harsh environments.
The power source for loads with no fixed
location
The BD01 system is ideally suited for the power
supply (up to 160 A) in workshops and trade
premises. The trunking units are easy and quick
to put together. The anti-rotation feature on the
tap-off units makes sure that the units are
correctly fitted and allows for easy retrofitting
even while the production is running.

Universal power distribution
The BD2 system (up to 1250 A) can supply
power to medium-size loads in buildings and in
all industrial applications. Prefabricated tap-off
units fitted with many differing component
combinations make this equipment universally
applicable. Two standard frame sizes covering
all current ratings simplify stock keeping and
planning.
Safe and reliable power transmission in the
petrochemical industry
The PEC resin-insulated system, up to 6000 A,
has a high degree of insulation protection and
thus an enormous resistance to external interfe-
rence factors. This ensures safe and reliable
transport of power even in rough weather or in
highly dust and dirt and corrosion polluted
industrial environments. Typical applications of
this system is the petrochemical industry, waste
incinerators and power stations.
Siemens offers modular component cabinets for indication, control and monitoring of the flow of power through busbar trunking systems. These cabinets are equipped with bus High system serviceability in production
interfaces, control circuit devices and power meters. The louvred LD busbar trunking system, up to 5000 A, is the system for transporting current in production lines with a large energy require-ment, such as in the automotive industry. A separate PE busbar ensures that the protective device in such a system responds reliably even if the current paths are relatively long. The high short-circuit rating allows medium-voltage switches to be used as protective elements for the transmission of power between transformer and main circuit-breaker. Tap-off units up to 1250 A available as standard.
Flexible power distribution in multi-storey
buildings
The LX sandwich-style system, up to 6300 A, is
used where large quantities of power need to be
transported, uninfluenced by the mounting posi-
tion of the system.

The voltage drop over longer distances must be taken into account.
3 Since the overall short-circuit rating of the complete run is based on the smaller LD system, either the complete run must be limited to this value at the feeder or the short-circuit current must be limited to the lower value upstream of the reduction unit, e.g. by a coupling unit  Protective sleeve, part 1 with a circuit-breaker.
 Protective sleeve, part 2 The smaller LD system must not be loaded with more than its permissible rated current.
The protective sleeve is not a substitute for the fire barrier.
Reduction units are equipped with a fixed point at the factory and are thus to be regarded as engineered fixed points.
With regard to the reduction to a busbar system with a lower rated current, the loop impedance must be calculated using the lowest prospective single-pole earth-fault current.

Parallel connection of LD runs
For economic reasons, it may be worthwhile to lay two runs with aluminium conductors instead of one LD busbar system with copper conductors.
Parallel connection of LD runs allows high currents to be carried. However, the voltage drop must be taken into account.
• Lighter mounting weight than when high currents are transmitted via a single busbar run.
• The option of using the basic components for other configurations, particularly in distribution installations which are modified frequently.
A lateral clearance of  0.1 m is required between the parallel runs in order to allow the single-bolt clamp ter-minal to be tightenend, as well as a lateral clearance from the building structure and other obstructions of When the fire barrier is used, the remaining space between the busbar trunking systems in the wall/ceil-ing cutout must also be filled with fireproof mortar.
The runs should always be positioned along one another.

Phase sequence reversal units
When carrying power over long distances using LDA(C) busbar trunking systems, a voltage drop of variable mag-nitude occurs. The voltage drop is caused by the arrange-ment of the conductors. The impedance values (details in the Technical data section) and the voltage drop resulting from them are determined as a mean value during type testing.
The use of three phase sequence reversal units achieve that the magnitude of the voltage drop in all three phases corresponds to this mean value. In practice, one phase sequence reversal unit is positioned after each third of the total length of the busbar run. Phase sequence reversal units are available on request.
Phase sequence reversal units are used where a low bal-anced voltage drop is to be achieved in a power transmis-sion system and where power is carried over long dis-tances at high load levels. 3 A phase sequence reversal unit is used for each third of the total length of the busbar run. A total of three phase sequence reversal units is therefore required.

We recommend centages of the list prices. Calculation of the surcharges will be therefore that you combine several small orders. Where this is governed by the official Al quotation for aluminum and by the not possible, we unfortunately find it necessary to charge a Cu-DEL quotation applying on the date of receipt of order or of processing supplement of € 20.-- to cover our costs for order processing and invoicing for all orders with a net goods value of less than € 250.--.
For the products in this catalog, aluminum and copper are inclu-ded in the prices on the basis of 150,-- €/100 kg. Aluminum and copper quotations above that amount are calculated on the ba-sis of the month previous to invoicing.
