IEC 60071-1:20 06+A1:2010适用于三相交流。设备最高电压高于1 kV的系统。它规定了设备和这些系统安装的相间、相间和纵向绝缘额定耐压的选择程序。它还给出了应从中选择额定耐压的标准耐压列表。本标准建议所选的耐压应与设备的最高电压相关联。该协会仅用于绝缘协调目的。本标准不包括人体安全要求。虽然本标准的原则也适用于输电线路绝缘，但其耐压值可能与标准额定耐压不同。设备委员会负责根据本标准的建议，规定适用于相关设备的额定耐压和测试程序。注:在IEC 60071-2《应用指南》中，详细说明了本标准中给出的所有绝缘协调规则，特别是标准额定耐压与设备最高电压的关联。当一组以上的标准额定耐受电压与设备的相同最高电压相关时，为选择最合适的一组提供指导。根据IEC指南108，该出版物具有水平标准的地位。 本合并版本由第八版（2006年）组成 及其修正案1（2010年）。因此，无须在 本出版物的补充。

IEC 60071-1:2006+A1:2010 applies to three-phase a.c. systems having a highest voltage for equipment above 1 kV. It specifies the procedure for the selection of the rated withstand voltages for the phase-to-earth, phase-to-phase and longitudinal insulation of the equipment and the installations of these systems. It also gives the lists of the standard withstand voltages from which the rated withstand voltages should be selected. This standard recommends that the selected withstand voltages should be associated with the highest voltage for equipment. This association is for insulation co-ordination purposes only. The requirements for human safety are not covered by this standard. Although the principles of this standard also apply to transmission line insulation, the values of their withstand voltages may be different from the standard rated withstand voltages. The apparatus committees are responsible for specifying the rated withstand voltages and the test procedures suitable for the relevant equipment taking into consideration the recommendations of this standard. NOTE In IEC 60071-2, Application Guide, all rules for insulation co ordination given in this standard are justified in detail, in particular the association of the standard rated withstand voltages with the highest voltage for equipment. When more than one set of standard rated withstand voltages is associated with the same highest voltage for equipment, guidance is provided for the selection of the most suitable set. This publication has the status of a horizontal standard in accordance with IEC Guide 108. This consolidated version consists of the eigth edition (2006) and its amendment 1 (2010). Therefore, no need to order amendment in addition to this publication.
