高压架空送电线路的导线选型

Conductor Selection of High Voltage Overhead Transmission Lines

通过对ＬＧＪ—４００／３５与ＬＧＪ—４００／５０两种钢芯铝绞线在同一气象条件，相同塔高在完全平地上施放档距不同的情况下，进行线路主要项目的分析对比及技术经济比较。说明了ＬＧＪ—４００／３５导线运行可靠、安全并降低了送电线路的造价。

Under the same meteorological condition,same height of tower,and stringing in different spans between towers in plan area,analysis and comparison were made technologically and economically with the major indexes of two types of LGJ—400/35 and LGJ—400/50 steel core aluminum stranded conductors.The result indicates that LGJ—400/35 can operate more reliably,securely and reduce the construction cost of the transmission line.
