A method to define subspan lengths for transmission line bundled conductors in view of subspan oscillations, aeolian vibration and torsional instabilities consideration. Part 1. mathematical model of subspan oscillations

摘要

A modification of the wind-induced subspan oscillations mathematical model is proposed which gives way to carry out multi-variant calculations of subspan oscillation amplitudes, aimed to choose optimal spacers location along the Transmission Linespans with bundled conductors. The problem of subspan lengths choice is solved to fit the project engineers approach.
