Cable Termination Structures

Support steel for cable terminations, risers, and underground-to-overhead circuit transitions.

What It Is

Underground to Overhead

Cable termination structures support outdoor cable terminations—sometimes called potheads—along with riser pipes, clamps, cable bus, and related connection hardware where an underground circuit transitions to overhead conductor or substation bus. The arrangement must preserve the specified phase spacing, cable bend and support requirements, access, and electrical clearances.

These structures are typically developed around approved cable-system and termination-hardware information. SteelCon fabricates the drawing-defined racks, mounting plates, platforms, riser supports, grounding attachments, and anchorage, then match-marks and packages the project-specific assembly for delivery.
