A common definition of ruling spän is a level dead-end span that gives the same change in tension from changes in loading, creep, and/or temperature as that in a series of suspension spans between two dead-end structures [2].
An Actual Ruling Span is an equivalent span length based on the total length and average tension of the conductor in a series of spans which is being pulled ... |
Abstract—The ruling span concept is widely used to calculate sags and tensions for new overhead transmission lines and for up- grading existing lines. |
The ruling span concept is widely used to calculate sags and tensions for new overhead transmission lines and for upgrading existing lines. It provides ... |
