Anotation

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 LIEC 60794-3-20:2016 sapplique aux cables optiques de telecommunication aeriens autoporteurs. Les exigences de la specification intermediaire IEC 60794-3 pour les cables installes dans des conduites, enterres et aeriens sont applicables aux cables relevant de la presente norme. Dans ce contexte, on entend par cable de telecommunication aerien autoporteur un cable dont la construction integre suffisamment delements de renfort pour quil puisse etre suspendu a des poteaux et des dispositifs analogues sans laide dun autre fil ou conducteur de support. Les cables ADSS installes sur des lignes dalimentation qui necessitent un materiau de gainage special pour la resistance au cheminement et a lerosion, et dautres constructions prevues pour des applications a haute tension ne sont pas couverts par la presente norme. Des specifications particulieres peuvent etre etablies en se fondant sur la presente specification de famille. Cette troisieme edition annule et remplace la deuxieme edition parue en 2009. Elle constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - la specification a ete simplifiee en sappuyant sur les references a lIEC 60794-1-1, lIEC 60794-1-2 et la serie IEC 60794-3; - lannexe contenant le tableau MICE a ete supprimee; - une annexe donnant des exemples a ete ajoutee.
