标准范围

IEC 63248:2022规定了直径范围为但不限于1.25 mm至5.50 mm的电线的特性。本文件适用于用于电力传输目的的同心层架空绞合导体或用于制造同心层架空绞合导体芯的绞合前的涂覆或包覆金属线。表A.1列出了各种导线类型及其名称。出于计算目的，使用附录B中列出的值。本第一版取消并取代了1993年出版的IEC 61232第一版和1997年出版的IEC 60888第一版。本版构成技术修订版。与IEC 61232和IEC 60888之前版本相比，本版本包括以下重大技术变更:a)导线名称已被修改和分组；b)去除2级镀锌线；c)添加了新的导线名称；d)添加了铝包FeNi36线；e)增加了先进的锌铝合金涂层钢丝。

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.
