Apstrakt

IEC 60794-1-126: 2026 defines the test procedures used to establish uniform requirements for mechanical performance – galloping. It applies to optical fibre cables like ADSS, OPGW or OPPC that can be exposed to galloping phenomena. 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 Method E26 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 the previous edition:
a) Addition of "for ADSS" and "for OPGW and OPPC" in 4.7, a);
b) Addition of "L4" in Figure 1 and in 4.7, b);
c) Change of the specified static sag angle to ≤ 1,5±0,5°;
d) Improvement of Figure 1;
