About this app

Catenary Cables revolutionizes the sagging process for overhead transmission line conductors, making it more accurate, precise, and efficient. Traditional methods in the IEEE Guide to the Installation of Overhead Transmission Line Conductors rely on approximate parabolic equations, leading to time-consuming calculations and guaranteed inaccuracies. Catenary Cables, however, leverages the more precise catenary expressions to deliver accurate results right from the start. Experience the benefits of flexible transit setup locations and unmatched sag accuracy while saving countless hours!
