5.2成型线

本标准认可三种生产工艺。一是单线在一个工艺过程中被成型，绞合是在另一工艺过程中进行。

第二种方法是单线成型和单线绞合在一次操作中完成。第三种方法是先绞合一层圆单线，然后将此层

紧压成圆形截面圆形单线的其他层可被绞合和紧压或成型单线的其他层可被纹合在紧压的芯线上

在任何情况下，材料都应符合GB/T17048或JB/T8134要求。

在第一种情况下，试验应在纹合前的成型单线上进行，并且其性能应基于等效线径进行计算。在其

GB/T20141-2006/IEC62219:2002

他情况下，试验应在成型和绞合前的圆形单线上进行，并且其性能应基于成型之前的圆形单线直径进行

计算。

在绞合后如果要求对个别的单线进行试验，供需双方应在合同签订之前约定
