标准摘要
[中文适用范围]： 本部分IEC 61466适用于额定电压大于1000V且频率不超过100Hz的交流架空配电线路中，机械负载（SML）为40 kN和70 kN至600 kN的复合绝缘子串单元。它也适用于变电站或铁路应用中类似设计的绝缘子。本标准适用于符合IEC 61466-1的复合型绝缘子串单元。本标准规定了用于架空配电线路的复合绝缘子串单元的电气和尺寸特性的指定值，最高最小雷电冲击耐受电压（BIL）水平为325 kV至3100 kV，机械负载（SML）为40 kN和70 kN至600 kN。 [外文原描述]： IEC 61466-2:1998+A1:2002+A2:2018 is applicable to composite string insulators with a specified mechanical load (SML) of 40 kN and 70 kN for a.c. overhead distribution lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators of similar design used in substations or on electric traction lines. This consolidated version consists of the first edition (1998), its amendment 1 (2002) and its amendment 2 (2018). Therefore, no need to order amendment in addition to this publication.
