Project Information
Client: City of
Barron
Contact: Dave Krause, Krause Power
Engineering, LLC
Site Location: Barron, Wisconsin
Municipal Utility: Barron Water & Light
Parent Utility: XCEL Energy
General Description
Barron Water and Light is the municipal utility for Barron
County, Wisconsin. Barron is home to more than 200
businesses and industries, and surrounded by nearly 45,000
local residents. Barron Water and Light is served by parent
utility XCEL Energy. The utility recognized the need to
replace the old unreliable switchgear without replacing the
incoming cables and termination. A consulting engineer was
hired to write specifications and perform the technical
evaluations of the proposals, from which, Shallbetter was
selected out of the group of qualified suppliers.
Project
Challenges
The existing switchgear incorporated utility metering from
the 1960’s. The new switchgear had to meet XCEL Energy’s
approval and specification without increasing the physical
size of the cubicle. Shallbetter’s engineering department
worked with Krause Construction and XCEL to achieve the
design without delaying the project. Shallbetter overcame
the aggressive shipping schedule. The order was issued in
early 2009 and had to be delivered to the job-site by mid
2009. This project’s overall life cycle was less than 22
weeks. This included drawing approval and component
purchasing. Shallbetter pre-purchased all the long lead-time
components within 2 weeks of order placement. This allowed
Shallbetter to maintain the aggressive shipping schedule.
The Shallbetter engineering staff expedited the drawings for
approval and was approved quickly based on the three
dimensional drawings showing conduit locations and
termination heights.

Sheltered-Aisle / Switchgear Features:
The walk-in sheltered-aisle / switchgear have many
features provided for the comfort of the operator
and the overall performance.
These features include:
• NEMA 3R construction w/ 11 gauge galvanneal steel.
• Heavy duty 6” channel base for added support.
• Base undercoating for added protection
• Interior / exterior paint finish meets or exceeds
ANSI-C57.12.28 paint specifications.
• 120/240V CPT & panel board for aisle power.
• XCEL Energy utility metering.
• Cutler Hammer 15kV, 1200A vacuum circuit breakers.
• Schweitzer protective relaying for the main and
feeders.

“I
couldn’t have wished for anything better, the
Shallbetter service team was very experienced and
well trained. All minor issues recognized during
final installation and testing were addressed
instantly. I would recommend Shallbetter, Inc. for
projects like this one in the future.” |

Shallbetter Inc.
Shallbetter Inc. met and matched existing
footprints, conduit locations, and existing cable
heights without any past drawings to reference.
They overcame installation challenges without
disturbing the overhead power lines, met the
decommission and installation of new gear time-frame
of only one week, and their service team was also
hired to help with installation of the new
switchgear. Shallbetter’s engineering and production
capabilities added value through customization,
quality, and service, successfully delivering the
completion of this project as scheduled.
