The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
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.
