CanBrass software
PD202428
CanBrass software can be used to design the busbar trunking line.
The easy-to-use program creates a graphic model of the line, determines the
length and draws up the list of Canalis KT parts to order.
The Canalis KT line is easy to specify simply by indicating the required dimensions.
However, it is strongly advised to use the shortest and simplest path possible
between the transformer and the switchboard.
It is important to carefully plan the layout of the transformer and switchboard in
order to use:
b the maximum number of standard components rather than made-to-measure
components,
b the minimum number of components for changing direction,
b straight made-to-measure components rather than made-to-measure
components for changing direction.
Advice
Before defining your busbar trunking run, it is recommended you pay particular
attention to the various parameters which could be detrimental to the installation.

the top.
Reserve a space between the busbar trunking and the ceiling equal to 2 times the
busbar trunking height (variable depending on the rating, see “Catalogue numbers

Modification of the busbar trunking height
By slightly increasing dimension “Z”, replace a made to measure elbow feed
connector with a standard feed connector and standard elbow section.
When choosing the layout of the electrical installation, it is important care is taken
when positioning the neutral between the transformer and the switchboard.
If the neutral position is different to that planned, it is recommended the transformer
is moved, if possible, to align the neutral with respect to the switchboard’s neutral.
When it is not possible to move the transformer, it is recommended the phase order
in the switchboard is inversed.
If this cannot be done, use the phase and neutral transposition section.

A support point as close as possible to the connections is needed because
transformers, generator sets and switchboards must not support the weight of the
busbar trunking.
In some industries, for service continuity reasons, transformers may be replaced
quickly. The busbar trunking must be able to support itself.
Edgewise horizontal installation

The maximum recommended distance between supports is 3 metres.
In all cases, provide for 2 supports for 4 metre sections.
For clamping busbar trunking to support brackets, see page K9AE41000/16.
Flat horizontal installation

Layout advice
Anticipate unexpected worksite
problems
Installation guide
Canalis KTA
In order to cope with dimensional differences between the drawings and actual
dimensions, it is desirable to provide an adjustable section or to leave a section
undecided for each partial run.
Adjustable section
DD202483
It has an initial length of 1300 mm and can be reduced or extended by the
installation contractor at the worksite (± 200 mm).
By planning the use of an adjustable section when producing the drawings, it can
be ordered with the rest of the material, without needing to wait until the job is
finished. It therefore allows the overall project completion time to be reduced.
DD210908
Allow a nominal dimension of 1300 mm on the drawing to guarantee an adjustment
of ± 200 mm on-site.
This section will be ordered after the gap to be filled has been measured at the end
of the job. To optimise its delivery to site, prefer a straight section with a length of
less than 2 metres rather than made to measure elbows.

Layout recommendations for adjustable
or undecided sections
In order to provide for the place needed for an adjustable or undecided section,
install the elbows and the sections attached to the elbows in each angle (support
each assembly using 2 supports on each straight section).
DD210994
Design and
installation guide
DD210908
On the drawing, provide a minimum dimension of 700 mm to guarantee an
adjustment of ± 200 mm on-site. The minimum length of straight sections being
equal to 500 mm.
And then complete the layout with standard and made to measure straight
sections.

DD202446
Expansion poses a problem when:
b the runs are made up of long straight sections,
b when the busbar trunking passes through an expansion joint between two
buildings.
Long part runs
Electrical busbar trunking can be subjected to a multitude of load variations during
its service life (e.g. day / night, summer / winter) which cause temperature rise
differences and thus variable expansions.
To absorb expansion in a Canalis KT busbar trunking, a specific section must be
used: the expansion section.
Horizontal runs without tap-off units
If the busbar trunking length is greater than 30 metres, provide for expansion
sections and appropriate blocking means. The ends and, in some cases, the
centre of part runs must be blocked in order to direct the extensions towards the
expansion sections.

For correct system operation, the expansion of the part run in question must be
directed towards the expansion section.
This implies:
b the busbar trunking must be free from all longitudinal movement on its supports,
b the expansion section must be blocked on the opposite side to that by which it is
pushed.

Canalis KT enables power distribution to each floor of multi-storey buildings (office
buildings, hotels, hospitals, etc).
In this application, Canalis KT retains all its construction principles:
Vertically mounted, the protection degree of the KT busbar trunking is IP55 as
standard.
Installing a rising main
1 Installation principle
Installation at each floor of:
b a 2 metre distribution section,
b a made to measure transport section to go through the floor slab,
b a busbar trunking support,
b up to 3 x 160 A tap-off units or a 250 or 400 A tap-off unit and a 160 A tap-off unit.
2 Installation feed
The installation feed is achieved using either a cable box or by direct connection to
an electrical distribution switchboard.
3 Busbar trunking supports
The supports fix the vertical run section to the building structure. a floor slab
support. It can be fixed to either the wall, to a wall bracket or directly to the floor,
This type of fixing support has the following advantages:
b fitting to either the wall, to a wall bracket or directly to the floor,
b height adjustment to make up for positioning errors,
b depth adjustment from 50 to100 mm,
b spring adjustment to ensure distribution of the load at each floor,
b absorption of building stresses with respect to the busbar trunking (expansion,
vibration, etc) thanks to the springs.

This guide may be used to:
v select the connection best suited to your installation (incoming direction, trunking
installed flat or edgewise, different phase order),
v check the total height of the connection with respect to the ceiling, i.e.
dimension Z0 + Z2 (100 mm minimum clearance required between top of
connection and ceiling),
v optimise the connection by ensuring that (Z0 + Z1)switchboard = (Z0 + Z1)transformer to
avoid having to use elbows and zed units,
v position the fixing devices used to support the trunking.

Connection to Okken and
Prisma Plus LV switchboards
By Canalis interface
Installation guide
Canalis KTA
PD202328
Switchboards can be equipped with connections for Canalis KT. Jointing with the
switchboard is via a standard run component (straight length, elbow, etc.) and a
jointing unit (identical to those used between line components). The trunking enters
the switchboard via the top (roof).
Switchboard connections are available from 800 to 4000 A.

Connections are tested and qualified under normal operating conditions in
terms of temperature rise (∆θ) and short-circuit currents (Isc).
The panel builder receives and connects the Canalis KT interface in the workshop.
The phase order at the interface output can be adapted if necessary (this
information must be forwarded to the panel builder).
The switchboard is then delivered to the site and the trunking can be rapidly
connected using a simple jointing unit with torque nuts to ensure the correct
tightening torque.

PD202434
The Trihal dry-type transformers are supplied with a specific interface tested to
receive the Canalis KT busbar trunking. Jointing with the switchboard is achieved
using a standard run section (straight, elbow section, etc) and a joint block identical
to that for connecting run elements.
The Canalis KT/ dry type transformer interface, which is fitted to the transformer,
is designed to accept the transformer’s 25 % overload in the case of forced
ventilation.
The connections are tested and qualified in normal operating conditions with
respect to temperature rise (∆θ) and short-circuits (Isc).
The busbar trunking is quickly connected to the dry-type transformer using a simple
joint block with torque nuts, guaranteeing tightening torque.

If the phase order of
the busbar trunking is
different to that of the
switchboard’s busbars, it
is recommended a phase
inversion is carried out
in the switchboard. If
this cannot be done, use
the phase and neutral
transposition section.
For more information,
see the “Description”
section, page

Installation guide
Canalis KTA
PD202330
Canalis KT can be connected to cast resin transformers using a universal feed.
The connection is made using a flexible busbar (connection plates or braids) to
avoid transmitting vibrations and expansions. The connection plates are made up
of either insulated or non-insulated flexible copper bars, drilled at one or both ends.
A nut and bolt kit allows connection to the feed.
The connections use torque-head bolts which provide both ease of installation and
visual inspection of correct tightening before energising.
If the transformer is supplied with panels, provide for an additional cover to
maintain the protection degree.
