Sheltered Aisle
35kV Switchgear
|
|

Data center comprising 13 megawatts of critical load and 44,000 square feet of raised-floor space.
Walk-in Sheltered Aisle
Shallbetter Inc. designed and
constructed the 35kV outdoor metal-clad switchgear
line-up
along with the walk-in, sheltered aisle for Power
Distribution Systems.
The 35kV metal-clad switchgear is
directly connected to the power company utility incoming
service and provides distribution electrical power to a Data
Center having in excess of 13mW of computer loads.
The Walk-in Sheltered Aisle
is a fully constructed
outdoor enclosure that
supports either metal-enclosed or metal-clad switchgear and
MCC. They can be
lined up to incorporate MV and LV controls or paralleling
systems for co-gen or renewable energy. The
Walk-in Sheltered Aisle provides an
innovative new approach to the traditional ‘open air’ or
‘lattice structure’ substation and an economical alternative
to traditional metal-clad switchgear. By putting equipment
inside, the Walk-in Sheltered Aisle offers increased
reliability for power distribution and turns outages from
weather or animal intruders into a thing of the past.
