帽式和针式绝缘子组串的特性

[中文适用范围]： 适用于标称电压大于 1 000 V、频率不大于 100 Hz 的交流架空线路、带有陶瓷材料或玻璃绝缘部件的帽针式串绝缘子单元，以及用于变电站。指定帽和销类型的串绝缘子单元的机械和尺寸特性值： 1) 带有球窝联轴器名称 U 40 BS 至 U 530 BL 2) 带有 U 形接头和舌形联轴器名称 U 60 C 至 U 210 CL。注： - 对于在严重污染区域使用以及在直流系统上使用的绝缘体，请参见 IEC 438。 [外文原描述]： Applies to string insulator units of the cap and pin type with insulating parts of ceramic material or glass, intended for a.c. overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz and to insulators of similar design used in substations. Specifies values of mechanical and dimensional characteristics for string insulator units of the cap and pin type: 1) with ball and socket couplings designations U 40 BS to U 530 BL 2) with clevis and tongue couplings designations U 60 C to U 210 CL. Note: - For use in heavily polluted areas and for insulators for use on direct current systems, see IEC 438.
