Using this calculator
Inputs and method
Choose the location and conductor category, define the span and check-area geometry, then enter a governing sag or calculate it from horizontal tension and conductor weight. Optional elevations place the complete profile on a common datum.
Design use
Confirm the location classification, attachment elevations, surface elevations, allowances, and governing project condition. The result is only as reliable as the entered profile data.
