1.3.3 Bracing
Incoming SSIS buses are inherently braced by their mechanical
design. Output cables are clamped in place using cable cleats and
vertical section braces.

brackets.
1.3.4 Arc resistant features
The XGIS design is arc resistant and offers designs with attachment
points for arc ducts at the sides or rear of the vertical section. If an
XGIS vertical section is configured for arc resistance, exhaust flaps
to integrate the vertical section into an arc resistant lineup prevent
the use of top-mounted voltage transformers in the vertical section
in which the arc duct attaches to the lineup.
Arc resistant lineups can be designed for arc gas exhaust from the
lineup left end, lineup right end, or the rear of any vertical section.
For more information, refer to IB022019EN.
1.3.5 Optional features
Not every option can be furnished on every vertical section
configuration. Following is a list of options. Whether any option can
be included on a project will depend upon on the vertical section
configuration applied.
3PDS locking features
In addition to the standard locking features that prevent switch
closure or grounding, the 3PDS can be fitted with locking features
to lock the switch in the closed position or lock the switch in the
grounded position. These features include padlock and Kirk lock
mechanisms and are mounted above and below the 3PDS faceplate.
Auxiliary sections
XGIS vertical sections can be equipped with additional sections for
custom equipment such as relays, power supplies, communications
equipment, etc. These sections are bolted to the end of an XGIS
vertical section lineup and are available in two widths: 600 mm and
and
