Pfronten
Substation
The territory of Elektriziti:i.tswerke Reutte
GmbH utility includes what used to be
Fussen county, A 110 kV overhead transmission line transports the powel' (most
of it generated in hydro-electric facilities)
over the pass from the valley of the river
Inn to Fussen,
Since this line is at risk from avalanches
and falling rocks, a coupling point was
set up back in 1971 between the utilities
Allgi:i.uer Uberlandwerk (AUW) and the
Elektriziti:i.tswerke Reutte GmbH (EWR),
This facility was no longer up to presentday requirements, and couldn't be
expanded either,
So to ensure a continuingly dependable
supply of electricity, a new station had to
be built in Pfronten,
High-voltage

new 110/25 kV substation, a project
shared between AUW and the EW Reutte,
Environmental and landscaping concerns, togethel' with the need to ensure
reliable power supply into the future,
wel'8 crucial in the decision to opt for a
110 kV substation in SF6 gas insulated
design, The ground area requirement for
the substation was thus reduced to onetenth of what would have been needed
for an outdoor installation,
(
For the Pfronten transformer substation,
ABB supplied the SF6 gas insulated
110 kV switchgear, The ELK-0 range of
shockproof 3-phase metal enclosed
switchgear is dimensioned for rated voltages up to 170 kV. The resultant insulation reserve constitute a particular operational advantage in view of the high
lightning risk in this area,
The compact dimensions of the ELK-O
range meant the constl'uction volume
was 40 % less than originally planned,
even though space for 3 more 110 kV
feeders has all'8ady been provided, The
modular design of ELK-O switchgear
also offers an option for subsequent
expansion to fit the substation for changing requirements, For example, the existing installation can be expanded to form
a single-busbar system with double sectionalization, or a double-busbar system
if desired,
The buildings were constructed in the
style of local farmhouses - with lots of
wood and minimized asphalting, to
ensure that the new structure blended in
harmoniously with the surrounding countlyside, And a natural dip in the landscape was utilized as well,
After carefuly checking of potentiallocations, a suitable site was found for the

General Remarks
(
Beside the 25 kV switchgard further
important equipment for operation, control, protection and metering (accountig
AUW-EWR) are located in the groundfloor. The basement essentially contains
the battery, the remote control equipment, and the cable distribution and
cable outlet. All premises are fitted with
automatic fire alarm facilities.
A new service depot for the equipment
of the utilitie's operation Pfronten is
placed on the same site (store room,
tools depot, transport fleet, workshop,
etc.).

formet' substation went on line as early
as April 1994; the service depot on the
same site has been operational since
September.
Thanks to systematic use of the possibilities and advantages offered by modernday SF6 gas insulated switchgear, and
supportive cooperation between all participants, an optimum solution was found
for design and construction of the
Pfronten project, not only satisfying the
need fm a dependable power supply,
but addressing environmental and landscaping requirements as well.
Construction work on this project kicked
off in early May 1993. Since the high-voltage system was delivered in complete,
faCtorY-tested bays, erection and commissioning times were cut substantially.
Thanks to excellent input and commitment from everyone involved, the trans-
