摘要
耐热铝合金导线(NRLHGJ)是一种在发达国家应用比较多的新型架空导线,具有耐高温、强度高、载流量大的特点,但也有线损较大、高温运行时弧垂较大、配套产品不齐、运行经验不足的缺点。分析了城市送电线路的特点并对城区新建、改造送电线路中,使用相应截面的耐热铝合金导线和普通钢芯铝绞线(LGJ)的工程投资进行了比较。对耐热铝合金导线在城市送电线路中的应用进行了探讨。
The high-temperature aluminium alloy conductor(NRLHGJ) is a new type of overhead conductor that is largely used in developed countries,which possesses the features of high-temperature,high strength,large amount of current-carrying capacity and has defects such as large curve in high temperature operation,lack of fittings,lack of operation-experience etc.The author analyzes the characteristics of city zone transmission-line,compares the investment of newly-built with rebuilt transmission-line in city zone when using corresponding NRLHGJ and normal steel-cored aluminium conductor(LGJ), and inquires into the application of the NRLHGJ to city zone transmissionline.
