IEC 60794-3-20 Ed. 3.0 b:2016

IEC 60794-3-20:2016 covers optical self-supporting aerial telecommunication cables. Requirements of the sectional specification IEC 60794-3 for duct, buried and aerial cables are applicable to cables covered by this standard. Self-supporting aerial telecommunication cable in this context means a cable construction with sufficient strength members designed to be suspended on poles and similar devices without the aid of another supporting wire or conductor. ADSS cables installed on power lines which require special sheath material for tracking and erosion resistance and other constructions intended for high-voltage applications are not covered by this standard. Detail specifications may be prepared based on this family specification. This third edition cancels and replaces the second edition published in 2009. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

– the specification has been streamlined by cross-referencing IEC 60794-1-1, IEC 60794-1-2 and the IEC 60794-3 series;

– an annex containing the MICE table has been deleted;

– an annex on examples has been added. Keywords: optical self-supporting aerial telecommunication cables
