Spec-Fab Inc. carries on a tradition of over 60 years of continuous service to the Power Generating Industry in both the supplying and servicing of Isolated Phase Bus equipment.

A direct lineage of the transference of technical and manufacturing expertise, along with fabricating plant can be traced to the development of the IPB concept of 1937 when the IPB was introduced by I.T.E.

Since 1987 (when Spec-Fab started producing IPB equipment), Spec-Fab’s production has spanned the globe in new installations, retro-fits, and in the supply of service parts for plants that were originally built by Spec-Fab’s predecessors. Our IPB Division is responsible for the design, manufacture and adaptation of:

  • IPB - Isolated Phase Bus installations
  • Telescopic Disconnect Switches
  • Replacement components
  • Flexible Connectors
  • Custom Electrical
  • Non-electrical products
  • Custom Products and Design
