Sag‐Tension Calculations Valid for Any Line Geometry
Publication: Journal of Structural Engineering
Volume 116, Issue 9
Abstract
A new method for determining transmission line sags and tensions is proposed. The algorithm is based upon new elements developed explicitly for transmission line systems. These elements make it possible to analyze lines of any geometry under general loading, temperature, and creep history either clamped in the service condition or suspended in the construction sheaves. Because the elements are derived from true catenary components, the results, including exact clipping offsets and sag corrections, remain valid in any terrain. Examples are included that provide comparisons to traditional analysis methods.
