IEC 60228:2023规定了各种类型的电力电缆和电线中导体的标称横截面积，范围为0.5 mm2至3 500 mm2。还包括对电线数量和尺寸以及电阻值的要求。这些导体包括用于固定安装的电缆中的实心、绞合和美利肯、铜、铝和铝合金导体以及柔性铜导体。本文件不适用于电信用导线。本文件对特定类型电缆的适用性如电缆类型标准中所规定。除非在特定条款中另有规定，否则IEC 60028 ED4涉及成品电缆中的导体，而不涉及制造或供应用于包含在电缆中的导体。本文件中描述的导体以公制尺寸指定。资料性附件提供了补充信息，涵盖电阻测量的温度校正系数（附件B）和圆形导体尺寸限制指南（附件C）。根据IEC指南108，本文件具有横向出版物的地位。

IEC 60228:2023 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, IEC 60028 ED4 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). This document has the status of a horizontal publication in accordance with IEC Guide 108.
