摘　　要：介绍西班牙UnionFenosa电力公司将1条66kV输电线路升级改造为220kV紧凑型输电线路工程,涉及建设背景、改造前后的线路参数、机械特性及施工方法。实践证明,这种改造技术可使原有线路输电能力提高233%,比新建1条同样的220kV输电线路节省成本40%,环境影响小,并大大缩短工期。Spanish Union Fenosa Utility has completed a new 220kV compact superstructure transmission line by up-grading the existing structures for 66kV. This paper gives in detail the background of the retrofit, parameters and mechani-cal characteristics for the existing 66kV and the new 220kV lines, as well as constructing techniques. The most importantand significant benefits from this type of projects are 233% incresase in the power transfer capability of the existing line,40% cost saving with respect to the construction of a new line, environment impact reduction and considerable reduction inthe construction time.
