绝缘电缆的导体

[中文适用范围]： IEC 60228:2023 规定了各种类型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途的导体。本文件对特定类型电缆的适用性在该类型电缆的标准中指定。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，而不是包含在电缆中制造或提供的导体。本文档中描述的导体均按公制尺寸指定。资料性附录提供了补充信息，涵盖电阻测量的温度校正系数（附录 B）和圆形导体尺寸限制指南（附录 C）。根据 IEC 指南 108，本文件具有水平出版物的地位。 [外文原描述]： 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 .
