Electrical Power Distribution Systems


You are always open for business when you purchase power distribution units from our company based in Alta, Iowa. For more than 35 years, Gull Wing Industries, Inc. has proudly been an industry leader in custom designed and manufactured portable power sources for operations big and small. Our custom units meet NEC requirements and contain lockable doors, connected cables, and square D breakers.


Our GFlex System Series

This compact, lightweight portable power distributor is designed with portability and durability in mind. Available in G4, G6, G8, and G10 models, this system is UL and CUL listed. We welcome you to review our internal cut-away, side, back, front, and top view schematics.

Constructed from aluminum to reduce weight, connections, and wires, it is rainproof with lockable doors and features common copper buss systems and flexible in- and output configurations. It is designed with a 400 or 600 amp capability and configured to SQD QO, QOB, and QB breakers.

GW Series 

Our GW series portable power distribution system is rugged job after job, easy to handle, and brings the power unit to the job rather than taking the job site to the power pole.  Applications include job sites, plant maintenance, festivals, special events, and carnivals.  Built in 50 or 100 amp, 1 or 3 phase.

MGW Series

The MGW is our mini Gull Wing distribution system that is UL listed with modules that can be easily changed in the field for flexibility in the field.
