IEC 60794-4:20 18 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 60794-4:20 18涵盖了架空光缆和电缆元件的电缆结构、测试方法、光学、机械、环境和电气性能要求，这些光缆和电缆元件旨在沿着电力线(OCEPL)用作通信和控制光信号的高带宽传输介质，包括光地线(OPGW)、光相位导体(OPPC)、金属架空自-支撑电缆(MASS)、全介质自支撑电缆(ADSS)和光纤连接电缆(OPAC)。本文件不包括用于电话电线杆的图8光缆。IEC TR 62839-1建议根据要求向客户提供环境声明。这第二版取消并取代了2003年出版的第一版。此版本构成技术修订。？与上一版相比，此版本包括以下重大技术变更: a)通过交叉引用IEC 60794-1-1简化了规范； b)已删除型式试验或常规试验的分类； c)删除了电缆扭结试验； d)ADSS的蠕变试验参考IEC 60794-4-20。 关键词:架空光缆

IEC 60794-4:2018 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 60794-4:2018 covers cable construction, test methods, optical, mechanical, environmental and electrical performance requirements for aerial optical fibre cables and cable elements which are intended to be used along power lines (OCEPL) as a high bandwidth transport media for communications and control optical signals, including optical ground wires (OPGW), optical phase conductors (OPPC), metallic aerial self-supported cables (MASS), all-dielectric self-supporting cables (ADSS) and optical attached cables (OPAC). This document excludes figure-8 optical cables to be used on telephone utility poles. The IEC TR 62839-1 gives recommendations to provide the customer with the environmental declaration on request. This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision.？ This edition includes the following significant technical changes with respect to the previous edition:
a) the specification has been streamlined by cross-referencing IEC 60794-1-1;
b) the classification as type tests or routine tests has been deleted;
c) cable kink test has been deleted;
d) creep test for ADSS is referred to IEC 60794-4-20.
