标准摘要
[中文适用范围]： 本文档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、尺寸和测试要求，适用于固定安装，如配电网络或工业安装。额定交流电压为1 kV (Um = 1.2 kV)的电缆，如果由制造商声明，也可用于直流配电系统，其标称电压≤750 V DC（最大900 V DC）（带电导体与中性/地之间），或≤1500 V DC（最大1800 V DC）（两个带电导体之间）。直流系统的导体识别依据当地安装规范。本文件包括具有低火焰蔓延、低烟雾排放和无卤气体排放特性的电缆。不包含用于特殊安装和服务条件的电缆，例如用于架空网络、采矿行业、核电厂（围阻区内及周围）、海底使用或船舶应用，或直接连接光伏系统的电缆。 [外文原描述]： 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.
