摘　　要：高海拔区 75 0 k V输电线路在污秽较严重地区若采用电瓷或玻璃绝缘子 ,将导致串长过长 ,杆塔尺寸过大 ,工程造价明显提高。采用复合绝缘子是一个技术先进又切实可行的选择。本文分析了采用复合绝缘子的先进性和可行性问题 ,并提出了应关注的几个问题。There are many choices in the selection of insulators for 750 kV transmission line in high altitude area of China. If porcelain or glass insulators are selected, the insulator string will be too long, the tower of transmission line will be too large and cost for the project of 750 kV transmission line will be too expensive. Composite insulators will be a suitable choice with technological advantage. In this paper the advantage and practicability of composite insulators are analyzed. Several problems deal with the application of composite insulators are discussed.
