Summary

The Technical Brochure deals with Modelling of Aeolian vibrations of High-Temperature Low-Sag (HTLS) conductors, and includes recommendations for laboratory tests on conductors and fitting clamps. It was found that, mainly at low frequency, self-damping values of HTLS conductors at ambient temperature does not substantially differ from those of standard ACSR conductors (Aluminium Conductor Steel Reinforced), thus requiring a correct investigation about the need of additional damping to safely control the aeolian vibration level and, therefore, de-claiming that HTLS conductors are self-damping conductors.
