Sag of Transmission Line Calculator
Calculate the sag of a transmission line with supports at the same height.
Using the formula:
\[
S = \sqrt{\frac{L \,(L_c - L)}{8}}
\]
where \(L\) is the horizontal span and \(L_c\) is the cable length.
* Enter span (m) and cable length (m); cable length must be greater than span.
Step 1: Enter Parameters
Example: 200 m
Example: 210 m (must be greater than span)
