– Manually enter each span length and elevation difference, or import a structure list. The software calculates the ruling span.
– Choose primary conductor and overhead shield wire from library, or import new. O-calc Pro Line Design
– Define units (Imperial or Metric), global temperature range, and design code (NESC, IEC, etc.). – Manually enter each span length and elevation
This article provides a comprehensive deep dive into O-calc Pro Line Design, exploring its core functionalities, workflow integration, advanced features, and why it remains the indispensable tool for transmission and distribution engineers worldwide. O-calc Pro is a powerful software application developed by Onyx Power , specifically engineered for the mechanical analysis of overhead power lines. The "Line Design" module is the heart of the platform, enabling engineers to model conductor and overhead shield wire (static wire) systems under diverse environmental and loading conditions. – Define units (Imperial or Metric), global temperature
– Set stringing temperature (often 60°F) and desired initial tension (e.g., 20% RBS). O-calc Pro back-calculates the required sag and slack.
