Our free-standing self-supporting low-profile padmount switchgear can be customized to meet every switching and isolation configuration requirement for medium voltage distribution. Dead Front or Live Front padmount air-insulated and vacuum switchgear can be designed for a voltage class of 15kV – 35kV, with a current ranging from 200A – 600A and a fault closed of 40kA. An array of single-phase and three-phase styles can be fabricated for industrial, commercial, residential, or renewable energy applications.

Metal Enclosure Design


The metal enclosure is welded to a 3-inch galvanized channel base to reduce flexing and racking during installation.


The metal enclosure’s galvanized channel base, roof and walls are MIG welded throughout and grounded smooth to make the metal enclosure structure sturdy and water infiltration resistant.


Media blasting the metal enclosure removes metal impurities resulting in a rough surface that firmly adheres to the primer and finishing coat.


Once the metal enclosure has been primed, a sealant is applied to the seams to prevent water infiltration.


The metal enclosure is coated with 3 millimeters of epoxy primer and 3 millimeters of finishing to reduce the effect of corrosion. The epoxy coat is graffiti-resistant; use and adhesive remover to clean the defacement.

Metal Enclosure Benefits


When standardized metal enclosures do not meet your specifications due to site footprint requirements and limitations, Scott Manufacturing Solutions customizes metal enclosures to meet your specific requirements. Our 3-D modeling allows for erase in the visualization of the product, making customization seamless.


Metal enclosures are customized to comply with IEEE, NEMA, ANSI and Western Underground Committee.


Designed to withstand the test of time. The metal enclosure 3-inch galvanized channel base, welded throughout construction and 3 millimeters of primer and finish coat contribute to the metal enclosure longevity. Resulting in a long-term, cost-effective solution that can endure harsh environments.
