  1. Hello Sir
    Thank you for your useful and simple topics.
    in “Sample Calculation of Sag and Tension of Transmission Line – Even Elevation” there is a mistake in
    H1 = 25% RTS = 58, 900 * 0.25 = 15,450 N Mistake
    H1= 25% RTS = 81,800 * 0.25 = 20,450 N Correct
    The further calculations should be corrected based on above correction.
    I can not transfer 2 USD ,due to not having foreign accounts(sanctions over my country Iran)
    would you please do me a favor, post the :
    Conductor Sag and Tension Calculator – Even and Uneven Elevation
