摘　　要：通过简要总结国外为数不多的特高压架空输电线路光纤复合架空地线(OPGW)应用经验和我国超高压OPGW的运行经验,指出特高压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,在此基础上分析及提出特高压OPGW的系列设计选型建议:如采用更大单丝直径的全铝包钢绞合OPGW;深入研究地线(包括OPGW)的配置方式;设计使用新型的紧压型耐雷的OPGW;对OPGW选型和系列进行研究、分析,为特高压电网提供结构合理和性能优良的新型OPGW。By summarizing the operation experiences in a few ultra-high voltage OPGW＇s in foreign countries and those in the UHV OPGW in China, this paper indicates that UHV OPGW should have excellent lightning resistance, vibration prevention and corona resistance. Based on this conelusion, the author puts forward the recommendations in terms of the type selection of OPGW as follows： the use of all Al-elad steel conductors with larger diameters to make OPGW; deep study of the arrangement of ground wires including OPGW; design and use of new type of lightning resistant OPGW; investigation and analysis of the type selection and product series of OPGW to provide UHV power grid with new type of OPGW with reasonable eOllStructiou arid excellent performance.
