IEC 60794-3-20:20 16涵盖光学自支撑架空电信电缆。IEC 60794-3对管道、埋地和架空电缆的要求适用于本标准涵盖的电缆。在本文中，自支撑空中电信电缆是指具有足够强度构件的电缆结构，其被设计成在没有另一支撑线或导体的帮助下悬挂在杆和类似装置上。安装在电力线上的ADSS电缆，如果需要特殊的护套材料来跟踪和抗侵蚀，以及其他用于高压应用的结构，本标准不包括在内。详细质量标准可基于该系列质量标准编制。这第三版取消并取代了2009年出版的第二版。它构成技术修订。与上一版相比，此版本包括以下重大技术变更: -通过交叉引用IEC 60794-1-1、IEC 60794-1-2和IEC 60794-3系列，简化了本规范； -删除了载有MICE表的附件； -增加了关于实例的附件。 关键词:自承式架空电信光缆

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
