1THE SIS BUS BAR SYSTEM
1.1 SHORT DESCRIPTION
Construction ………….………………….
Fig. 1: Basic illustration of a bus bar
connection in a connection sleeve
The fully insulated bus bars comprise a conductor in the form
of a pipe or round material (E-Al or E-Cu) with solid insulation
made of epoxy resin impregnated paper (RIP).
For reasons of mechanical stability, adherence with transport
dimensions, handling on site and maximum dimensions
dictated by the production facility, bus bar systems typically are
made in sections. In order to ensure a continuous, potential-
free bus bar system, an insulated connection sleeve is installed
over the connection between the non-insulated, controlled bus
bar ends.
1 Contact tube
2Fully insulated bus bar
3 Earth connection
4 Fully insulated indoor connection sleeve
5 Contact spring
6 Flexible connector
Fig. 2: Indoor connection sleeve installed
(example)
The connection of two bus bar elements (Fig. 2/2) inside the
connection sleeve (Fig. 2/1) is established using flexible
connectors (Fig. 2/4) which offset small length tolerances
during installation, and the thermal expansion of the bars
during operation. The contact springs (Fig. 2/3) are installed on
the flexible connectors and touch the inside of the contact tube.
The connection sleeve and the bus bar elements are contact-
proof when operated within the technical specifications.
Fig. 3: Bellows on the outdoor connection
sleeve
Indoor connection sleeves (Fig. 2) are closed with an
aluminium sealing flange (Fig. 2/5) which ensures that the
connection of the connection sleeve on the bar is dust and
splash proof. Outdoor connection sleeves are manufactured
with a stainless steel protective tube. It is secured and sealed
off on the bar with a ring seal unit. A second seal to the bar is
provided by bellows (Fig. 3/2) which are secured to the bus bar
and connection sleeve using hose clamps (Fig. 3/1).

8 / 130
Fig. 4: Fixation unit (example)
Bus bars are installed on floors, ceilings or walls on a fixation
design which is specific to the respective order. An individual
fixation unit comprises, for example, brackets (Fig. 4/1), C-
profiles (Fig. 4/2), fixation clamps (Fig. 4/3) and bolted
connections (with T-bolts, conical spring washers and nuts, Fig.
4/4).
In general, an earthing bar or earthing cable has to be laid
parallel to the bus bar, to which all bars, connection sleeves,
and fixation must be connected and, subsequently, to the earth
potential.
Design …………………...…………………
Dimensions and designs are in line with the valid regulations
and standards. The drawing and serial number of the
respective bus bar is punched in at one end of the long side of
the flange connection, or on the face of round or pipe-shaped
connections. The bus bar elements are shown with an item
number in the assembly drawing. The drawing number is
shown underneath the respective item number in the
