光缆.第4部分:分规范.沿电力线的架空光缆

[中文适用范围]： This part of IEC 60794 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. [外文原描述]： 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.
