O-calc Pro Line Design ((install)) Jun 2026
A Midwest co-op had a 15-mile line using undersized ACSR conductor. Using O-calc Pro, they modeled a replacement with AAAC 636 kcmil. The software revealed that existing poles (40 ft class 3) would see final ice tensions 15% higher than NESC allowed. By increasing the stringing tension from 18% to 22% RBS and reducing span lengths at three river crossings, clearance was maintained without replacing all poles. Savings: $1.2 million.
The software generates a of the line, overlaying the conductor curve onto the terrain. It instantly flags clearance violations, prompting the user to adjust structure heights or re-tension the line. O-calc Pro Line Design

It is important to distinguish O-Calc Pro from other line design software like . While PLS-CADD is generally considered the industry standard for large-scale transmission line design, O-Calc Pro is specifically optimized for distribution pole plants.
If you want to dive deeper into configuring this software for your specific engineering needs, let me know:
The software features "stringing" capabilities, allowing engineers to run new wires across the entire length of a circuit after defining a new assembly. 3. Advanced Clearance Analysis
