(Main)Conductors of insulated cables (IEC 60228:2023)
Conductors of insulated cables (IEC 60228:2023)
This document specifies the nominal cross-sectional areas, in the range 0,5 mm2 to 3 500 mm2,
for conductors in electric power cables and cords of a wide range of types. Requirements for
numbers and sizes of wires and resistance values are also included. These conductors include
solid, stranded and Milliken, copper, aluminium and aluminium alloy conductors in cables for
fixed installations and flexible copper conductors.
This document does not apply to conductors for telecommunication purposes.
The applicability of this document to a particular type of cable is as specified in the standard
for the type of cable.
Unless specified otherwise in a particular clause, this document relates to the conductors in
the finished cable and not to the conductor as made or supplied for inclusion into a cable.
Conductors described in this document are specified in metric sizes.
Informative annexes provide supplementary information covering temperature correction
factors for resistance measurement (Annex B) and guidance on dimensional limits of circular
conductors (Annex C).
Leiter für Kabel und isolierte Leitungen (IEC 60228:2023)
Ames des câbles isolés (IEC 60228:2023)
L'IEC 60228:2023 spécifie les sections nominales, dans la plage de 0,5 mm2 à 3 500 mm2, des âmes d’un large éventail de types de câbles et de cordons électriques. Des exigences relatives au nombre et au diamètre des fils sont également spécifiées, ainsi que des valeurs de résistance. Les âmes concernées sont les âmes massives, câblées et segmentées, en cuivre, aluminium et alliage d’aluminium, destinées aux câbles pour installations fixes, ainsi que les âmes souples en cuivre. Le présent document ne s’applique pas aux âmes utilisées à des fins de télécommunication. L’applicabilité du présent document à un type de câble particulier est précisée dans la norme relative à ce type de câble. Sauf indication contraire dans un article particulier, le présent document porte sur les âmes des câbles terminés, et non sur les âmes seules ou fournies en vue d’une intégration dans un câble. Les âmes décrites dans le présent document sont spécifiées en tailles métriques. Des annexes informatives donnent des informations complémentaires sur les facteurs de correction de température à utiliser pour les mesures de résistance (Annexe B) et des recommandations sur les limites dimensionnelles des âmes circulaires (Annexe C).
Vodniki izoliranih kablov (IEC 60228:2023)
Ta dokument določa nazivne prereze vodnikov v električnih napajalnih kablih in vrvicah različnih vrst, v razponu od 0,5 mm2 do 3500 mm2. Vključene so tudi zahteve glede števila in velikosti žic ter vrednosti upornosti. Ti vodniki zajemajo trdne, pletene in segmentne vodnike iz bakra, aluminija in aluminijeve zlitine v kablih za stalno napeljavo ter gibke bakrene vodnike.
Ta dokument se ne uporablja za vodnike za telekomunikacijske namene.
Uporabnost tega dokumenta za določeno vrsto kabla je določena v standardu za zadevno vrsto kabla.
Ta dokument se navezuje na vodnike v dokončanem kablu in ne na vodnike, izdelane ali dobavljene za vključitev v kabel, razen če je v določeni točki navedeno drugače.
Vodniki, opisani v tem dokumentu, so podani v metričnih velikostih.
V informativnih dodatkih so podane dodatne informacije o korekcijskih faktorjih temperature za merjenje upornosti (dodatek B) in smernice za omejitve glede mer okroglih vodnikov (dodatek C).

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
