常用铝包钢绞线性能参数、短路电流及短路电流容量表（按国网与南网分类汇总）
|转至：输配电线路
在一根中心线芯周围螺旋绞上一层或多层铝包钢丝单线组成的绞线，其相邻层绞向相反，该绞线称为铝包钢绞线 （aluminium-clad steel conductors）。铝包钢绞线一般用于架空地线。▲图 铝包钢绞线结构
铝包钢绞线按导电率组别分为：14AC、20AC、23AC、27AC、30AC、33AC、35AC、40AC。对应的导电率为：14%IACS、20.3%IACS、23%IACS、27%IACS、30%IACS、33%IACS、35%IACS和40%IACS。国家电网有限公司的《导、地线采购标准》与中国南方电网有限责任公司的《35kV~500kV铝包钢绞线技术规范》使用的铝包钢绞线执行的标准有差异，国家电网有限公司的铝包钢绞线参数主要参考行业标准《铝包钢绞线》（YB/T 124-2017），中国南方电网有限责任公司铝包钢绞线参数主要参考国家标准《圆线同心绞架空导线》（GB∕T 1179-2017 ），因为两标准参数有差异，所以使用两家电网公司使用的采购标准或技术规范书时参数存在一定的差异，大家在做不同电网项目时一定要注意标准的差异。现小编根据采购标准或技术规范书中的型号整理编辑，增加计算其短路电流及短路电流容量后与大家分享。
