1250mm^2大截面导线压接施工技术

Compression construction technology of 1250mm^2 large section conductor

随着特高压电网建设的发展,特高压输电线路工程中应用1 250 mm^2大截面架空导线,对于大截面导线耐张管的压接施工工艺也发生着变化,通过改变压接顺序、压接预留长度、额定工作压力及压接工艺等影响因素进行了剖析,解决了大截面导线压接施工中出现松散、起灯笼、握着力及对边距超标等问题,说明1 250 mm^2大截面导线施工技术能满足特高压大截面导线施工质量和工程管理的要求。

With the development of UHV power grid construction,in the UHV transmission line project,the application of 1250 mm^2 large section overhead conductor to the pressure-connecting construction technology of large section conductor is also changed,by changing the order of the crimping,the length of the crimping,the rated working pressure and the crimping technology,it solves the problems of loose,lanterns,grip and exceeding the standard in the construction of large cross section conductor,and explains that the construction technology of 1 250 mm2 large section conductor can meet the requirements of construction quality and engineering management of UHV large section conductor.
