For multiple conductors per phase (bundled), define the bundle configuration.

O-Calc Pro is widely considered the industry standard for overhead electric utility structural analysis. Developed by chance encounters (and later acquired by ), it fills a specific niche: the detailed, physics-based analysis of wood, steel, and concrete poles under the strain of conductor loading. For multiple conductors per phase (bundled), define the

A utility needed to increase line ampacity from 650A to 900A using ACSS/TW conductor. O-calc Pro Line Design modeled the new conductor at 200°C emergency rating. It showed that sag would increase 3.5 feet in the longest crossing span. The solution: raise two tower arms and use larger insulator strings. The report was submitted to the state siting board for approval—granted 30 days earlier than typical. A utility needed to increase line ampacity from

Unlike generic structural tools, O-Calc Pro is pre-loaded with industry databases: standard pole classes, soil types, hardware libraries, and regional weather loading maps (NESC, ASCE, and Canadian standards).

He started by importing the LIDAR terrain data. The 3D model rendered the valley in stark grayscale: the creek bed, the tilted oak trees, the narrow gap where the old poles had been too short. Jeremy clicked . The algorithm ran for ninety seconds, then suggested a new path—creeping up the eastern ridge to avoid a known landslide zone, then dropping back down at a less severe angle. It added 0.7 miles of line but reduced the maximum wind load by 31%.
