标准摘要
[中文适用范围]： 本部分 IEC 60502 规定了额定交流电压为 1 kV (Um=1.2 kV) 和 3 kV (Um=3.6 kV) 的挤包固体绝缘电力电缆的结构、尺寸和试验要求，适用于固定安装，如配电网络或工业设施。 额定交流电压 1 kV (Um=1.2 kV) 的电缆如果制造商声明，也可以用于直流配电系统，其标称电压 ≤750 V DC (最大 900 V DC) 在带电导体与中性/地之间，或 ≤1500 V DC (最大 1800 V DC) 在两个带电导体之间。直流系统的适用芯线标识应符合当地安装规定。 注 1：IEC 60445 给出了直流系统线路导体首选芯线颜色的建议。然而，直流系统的当地安装规定可能已经包含特定的标识要求。 本文件包括在火灾情况下具有低火焰蔓延、低烟雾排放和无卤气体排放特性的电缆。 不包括特殊安装和使用条件的电缆，例如架空网络电缆、采矿工业电缆、核电站电缆（在安全壳区域内外）、海底或船舶应用电缆，或直接连接到光伏系统的电缆。 注 2：光伏系统电缆由 IEC 62930 涵盖。 [外文原描述]： IEC 60502-1:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60502-1:2021 specifies the construction, dimensions and test requirements of power cables with extruded solid insulation for rated AC voltages of 1 kV (Um = 1,2 kV) and 3 kV (Um = 3,6 kV) for fixed installations such as distribution networks or industrial installations. Cables of rated AC voltage 1 kV (Um = 1,2 kV) designed and tested in accordance with this document can also be used, if declared by the manufacturer, in DC distribution systems having their nominal voltage ≤ 750 V DC (with a maximum of 900 V DC) between a live conductor and neutral/earth, or ≤ 1 500 V DC (with a maximum 1 800 V DC) between two live conductors. Applicable core identification for DC systems are considered in accordance with local installation regulations.
