摘　　要：分析广州电网线路外绝缘现状,结合广州气候特点和线路安全稳定运行需要,根据全生命周期成本理论,对架空线路悬垂串型进行技术经济分析,并按照综合考虑输电线路防风偏、防污和防雷的性能要求,提出适于广州电网线路绝缘子选型及外绝缘优化的建议。According to the life cycle cost theory, the technical and economic analysis of suspension insulator selection is carried out by analyzing the external insulation status of electric transmission lines in Guangzhou and combining with the climate characteristics and safety and steady operation needs of electric transmission lines. And based on the comprehensive consideration on the Wind deviation, antipollution and prevention of lightning fauhs requirements, adviees and measures are put forward in the paper which are suitable to the type selection of insulators and optimization of external insulation for transmission lines in Guangzhou.

关 键 词：全生命周期成本(LCC) 绝缘子选型 外绝缘优化
