Composite string insulator units for overhead lines with a nominal voltage greater than 1 000 V - Part 2: Dimensional and electrical characteristics
标称电压大于1000V的架空线路用复合绝缘子串第2部分:尺寸和电气特性
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.
