摘　　要：国家电网公司关于"交流系统用盘形瓷或玻璃复合伞裙绝缘电子元件"企业标准,于2008年1月7日起正式颁布与实施。玻璃芯复合伞裙绝缘子自爆后不易被发现,存在安全隐患,应摒弃应用。瓷芯复合伞裙绝缘子应用于耐张双串,需要重新考虑耐张双串的结构、电气尺寸和绝缘、防雷配合,视情况确定是否需要安装高、低压端的均压环。瓷芯复合伞裙绝缘子在110,220kV线路上应用效果良好,说明瓷芯复合伞裙绝缘子可应用于耐张双串。SGCC＇ s enterprise standard, ＂Ceramic or Glass Composite Disk Insulation Electronic Components for AC System,＂ was issued and taken effect on Jan. 7, 2008. Because it is hard to be found when glass-core composite insulators burst, resulting in hidden trouble for safety, it should be abandoned. When ceramic-core composite insulator is used in strain insulator double string, however, the structure, as well as electric size and insulation and lightning prevention matching of the string must be reconsidered. The decision of installation of high and low voltage side grading rings should be determined by actual circumstances. The outcome of ceramic insulator used in 110 and 220 kV lines are satisfactory, meaning that it is suitable for strain insulator double strings.
