Annotation of standard text IEC 63248-ed.1.0 :
IEC 63248:2022 specifies the properties of wires in the diameter range of, but not limited to, 1,25 mm to 5,50 mm. This document is applicable to coated or cladded metallic wires before stranding used either as concentric lay overhead stranded conductors, or in the manufacture of cores for concentric lay overhead stranded conductors, for power transmission purposes. The various wire types and their designations are listed in Table A.1. For calculation purposes the values listed in Annex B are used. This first edition cancels and replaces the first edition of IEC 61232 published in 1993 and the first edition of IEC 60888 published in 1997. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions of IEC 61232 and IEC 60888: a) wire designations have been modified and grouped; b) wires with zinc coating class 2 were removed; c) new wire designations have been added; d) aluminium-clad FeNi36 wires have been added; e) advanced zinc-aluminium alloy coated steel wires have been added. IEC 63248:2022 specifie les proprietes des fils dont le diametre est compris, entre autres, dans la plage de 1,25 mm a 5,50 mm. Le present document s’applique aux fils metalliques revetus ou recouverts avant toronnage utilises soit comme conducteurs aeriens toronnes a couches concentriques, soit dans la fabrication d’ames pour conducteurs aeriens toronnes a couches concentriques, a des fins de transport d’energie electrique. Les differents types de fils et leurs designations sont enumeres dans le Tableau A.1 . Pour les calculs, les valeurs enumerees dans l’Annexe B sont utilisees. Cette premiere edition annule et remplace la premiere edition de l’IEC 61232 parue en 1993 et la premiere edition de l’IEC 60888 parue en 1997. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport aux editions precedentes de l’IEC 61232 et de l’IEC 60888: les designations des fils ont ete modifiees et regroupees; les fils revetus de zinc de classe 2 ont ete supprimes; de nouvelles designations des fils ont ete ajoutees; les fils FeNi36 recouverts d’aluminium ont ete ajoutes; les fils d’acier revetus d’un alliage zinc-aluminium avance ont ete ajoutes.
