IEC 60794-1-119:2025 applies to aerial optical fibre cables such as all-dielectric self-supporting (ADSS) cables, optical ground wire (OPGW) cables, and optical phase conductor (OPPC) cables that can be exposed to aeolian vibrations. This document defines the test procedures to establish uniform mechanical performance requirements relating to aeolian vibrations.全文を表示する
See IEC 60794 1 2 for general requirements and definitions and for a complete reference guide to test methods of all types.
This first edition cancels and replaces test method E19 of the first edition of IEC 60794 1 21 published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60794 1 21:
a) addition of a system to maintain a constant cable tension during the test as well as means to measure the free loop antinode amplitude;
b) definition of the cable load which is now fixed to 25 % of the rated tensile strength for OPGW/OPPC, or to the maximum installation tension (MIT) for ADSS cables;
c) addition of the target free loop peak-to-peak antinode amplitude to the procedure. The quality of the aeolian vibration motion is done through the average antinode
d) addition of fatigue damage and ovality changes of the optical core to 4.5.
