Ruling Span of Transmission Line Calculator

Calculate the ruling span using:
\[ L = \sqrt{\frac{8\,T\,S}{w}} \] where \(T\) is the maximum tension, \(S\) is the sag, and \(w\) is the weight per unit length.

* Enter values in SI units.

Maximum Tension, \( T \) (N):

Example: 10000 N

Maximum Sag, \( S \) (m):

Example: 5 m

Weight per Unit Length, \( w \) (N/m):

Example: 1 N/m
