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.
