摘　　要：对国外为数不多的特高压OPGW应用经验和我国超高压OPGW的运行经验进行分析可知,特高压OPGW必须具有良好的防雷特性、防振特性和耐电晕特性等技术特点。因此在我国特高压OPGW的系列设计选型中,应采用更大单丝直径的全铝包钢绞合OPGW,同时要深入研究地线(包括OPGW)的配置方式,设计使用新型的内层压缩型耐雷OPGW,开展OPGW选型和系列研究分析工作,为特高压电网提供结构合理、性能优良的新型OPGW。From analyzing limited experiences of foreign UHV OPGW applications and domestic UHV OPGW operating experiences, it is known that UHV OPGW should have such characteristics as good lightning protection, vibration proof and corona resistance, etc. Thus, during UHV OPGW selection, in order to provide OPGW with rational structure and high performance for UHV grid, stranded aluminum-clad steel OPGW with thicker strand should be used; the configttration of earthing cable （including OPGW） should also be studied; lightning proof OPGW with new compressed lining should be designed; OPGW selection and analyses should also be performed.
