Conductors for overhead lines - Aluminium and aluminium alloy wires for concentric lay stranded conductors

IEC 62641:2022 specifies the mechanical and electrical properties of round and formed wires for equivalent diameters up to the values according to Table 3 for aluminium and aluminium alloys and according to Table 4 for thermal resistant alloys. This document is applicable to aluminium and aluminium alloy wires for the manufacture of concentric lay overhead electrical stranded conductors with or without gap(s) for power transmission purposes. The various materials and their designations are listed in Table 1. For calculation purposes, the values listed in Table 1 are used. This first edition cancels and replaces the second edition of IEC 60104 published in 1987, the first edition of IEC 60121 published in 1960, the first edition of IEC 60889 published in 1987, and the first edition of IEC 62004 published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous editions of IEC 60104, IEC 60121, IEC 60889 and IEC 62004:
designations of aluminium alloys are modified;
aluminium alloys A4, AL4 and AL5 are added;
wire diameter ranges for indicating mechanical properties are modified and extended;
test methods are merged.

Conducteurs pour lignes aériennes - Fils d’aluminium et en alliage d’aluminium pour conducteurs toronnés à couches concentriques

La CEI 62641:2022 spécifie les propriétés mécaniques et électriques des fils ronds et de forme pour des diamètres équivalents jusqu’aux valeurs indiquées dans le Tableau 3 pour l’aluminium et les alliages d’aluminium et dans le Tableau 4 pour les alliages résistants à la chaleur. Le présent document s’applique aux fils d’aluminium et en alliage d’aluminium destinés à la fabrication de conducteurs toronnés à couches concentriques pour lignes électriques aériennes, avec ou sans espace(s) pour le transport d’énergie. Les différents matériaux et leurs désignations sont énumérés dans le Tableau 1. Les valeurs indiquées dans ce Tableau 1 sont utilisées pour les calculsCette première édition annule et remplace la deuxième édition de l’IEC 60104 parue en 1987, la première édition de l’IEC 60121 parue en 1960, la première édition de l’IEC 60889 parue en 1987 et la première édition de l’IEC 62004 parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport aux éditions précédentes de l’IEC 60104, l’IEC 60121, l’IEC 60889 et l’IEC 62004:
les désignations des alliages d’aluminium sont modifiées;
les alliages d’aluminium A4, AL4 et AL5 sont ajoutés;
les plages de diamètre du fil qui indiquent les propriétés mécaniques sont modifiées et étendues;
les méthodes d’essai sont fusionnées.

Vodniki za nadzemne vode - Aluminijaste žice in žice iz aluminijeve zlitine za koncentrične pletene vodnike (IEC 62641:2022)

Ta dokument določa mehanske in električne lastnosti okroglih oziroma oblikovanih žic za enakovredne premere do vrednosti, navedenih v preglednici 3 za aluminij in aluminijeve zlitine ter v preglednici 4 za toplotno odporne zlitine.
