Over time, aluminum strands stretch plastically under tension (creep). O-calc Pro includes built-in creep models based on conductor type and operating temperature. Result: more accurate "final" sag values after 10, 20, or 50 years. Without accounting for creep, lines may sag into vegetation midway through their lifespan.
However, if you are:
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. O-calc Pro Line Design
O-Calc Pro is not merely a mobile app or a simple voltage drop calculator. It is a suite of geospatially enabled engineering analysis tools designed specifically for the design, mapping, and structural analysis of overhead and underground utility lines. Without accounting for creep, lines may sag into
