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]. This span "rules" the conductor's sag and tension behaviour for the line section.
The ruling span concept is widely used to calculate sags and tensions for new overhead transmission lines and for upgrading existing lines. It provides ... |

conductor tension is increased until the sag in one or more suspension spans reaches the appropriate stringing sags based on the ruling span for the line ... |
Abstract—The ruling span concept is widely used to calculate sags and tensions for new overhead transmission lines and for up- grading existing lines. |
Оценка 5,0  (1) The document discusses the key components and design considerations for overhead transmission lines, including: 1. Conductors - the different types used ... |
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. |
