摘　　要：特高压交流试验示范工程扩建工程的软母线安装具有跨距大、跨越物多、导线截面大等特点,施工难度较大。提出了单导线展放、四导线同时展放2种软母线施工方案,经过技术论证,选择了四导线同时展放施工方案,现场施工全过程安全、顺利。In the expansion project of the UHV AC demonstration project, the installation of flexible busbar has great difficulty, which has the characteristics of large span, many spanned objects and big wire section. Therefore, two kinds of construction schemes are provided, including single-wire stringing and four-wire simultaneous stringing. According to technical argumentation, four-wire simultaneous stringing is optimal, of which the site operation is safety and successful.
