Transformer Cabinets
Custom transformer cabinets and NEMA-rated metal enclosures — fabricated and powder-coated entirely in-house.
Custom transformer cabinets and NEMA-rated metal enclosures — fabricated and powder-coated entirely in-house.
FabTek manufactures metal transformer cabinets at hundreds per month on a single shift — and everything is done in-house, no exceptions, including paint.
For utilities, transformer OEMs, EPC contractors, and data center builders, single-source control means tighter tolerances, consistent finishes, and schedules you can plan around. Every cabinet is a domestic build under an ISO 9001:2015 quality system at our facilities in Hazlehurst, Mississippi.
High-volume metal transformer cabinets, fabricated, welded, and finished in-house.
Enclosures built to custom NEMA ratings for indoor and outdoor service.
Sealed, weather-rated housings and pad-mount enclosures for field durability.
Send drawings or a spec — we fabricate to print, welded and bolted.
FabTek transformer cabinets and enclosures house and protect the electrical apparatus at the heart of the grid.
Utilities and transformer OEMs rely on them to enclose pad-mounted and substation transformers, switchgear, metering, and control equipment — shielding energized components from weather, wildlife, and tampering while keeping them accessible for service. Across investor-owned utilities, public power, EPC substation builds, and hyperscale data centers, these NEMA-rated, powder-coated enclosures stand up to decades of outdoor duty in the field.
