摘　　要：已建输电线路,由于导线截面已经确定,存在输送容量的极限。随着系统运行方式的变化,对已建线路提高输送容量的需求越来越多。提高已建线路的输送容量,有两种技术方案,一是拆除已建线路,新建使用大截面或多分裂导线的线路;二是保持已建线路铁塔不变,将已有导线更换为耐热导线。由于取得新建输电线路的走廊协议非常困难,而且投资巨大,因此,使用耐热导线,以达到提高输送容量的目的,在线路改造工程中的应用越来越广泛。结合枣庄地区的实际工程,探讨耐热导线,尤其是铝包殷钢芯超耐热铝合金绞线的应用,可为以后的线路扩容工程提供参考。The existing transmission lines ,because the conductor has been determined, the transmission capacity is determined. With the change of system operation mode,improving the transportation capacity of existing line is more and more important.To increase the transmission capacity of the line which has been built, there are two schemes, one is the reconstruction, the new use of large cross-section or multi conductor lines ;the other is the replacement for the heat-resisting wire.Due to the huge investment and Difficulties for obtain the new transmission line corridor agreement,heat-resistant wire is more and more widely used in line reconstruction project.Combined with practical engineering in Zaozhuang,the heat-resisting wire is discussed. The application of aluminum clad steel core super heat-resistant aluminum alloy wire can provide some reference for the future project.
