• NESC Heavy Loading (0.5” ice + 4 psf wind + temp)
• NESC Medium/Light
• Extreme Wind (70–150 mph per ASCE 7)
• Broken Wire (one or two conductors snapped)
• Maintenance/Climbing (100-300 lb point load)
• Construction (stringing tension)

Underground Transition Modules

While primarily an "overhead" tool, the Line Design module handles the transition from pole to underground riser. It analyzes the termination pole for the added weight of arresters, elbows, and the tension from the underground feeder pulling around a bend.

• Increase pole class or switch to steel/concrete.
• Add guy wires or down guys.
• Reduce span length.
• Lower conductor tension (increase sag).
• Move heavy equipment lower on the pole.

Systemic Analysis: Changes made to one pole (like increasing height or moving a guy wire) automatically update the tension and loading on adjacent poles in the line. NESC Heavy Loading (0
