铝包钢绞线（YB/T124-1997）发表评论(0)编辑词条

(1)分类见表7-230。表7-230铝包钢绞线按断面结构分断面
  
 
 
结构1×31×71×191×37注：1.铝包钢绞线按导电率分为：20AC、23AC、27AC、30AC、33AC、40AC六个组别，其相应的导电率为20.3％、23％、27％、30％、33％和40％IACS。     2.铝包钢绞线的代号为：LBGJ        ┬ ┬ ┬ ┬ ┬ ┬
        │ │ │ │ │ └导电率(%IACS)
        │ │ │ │ └──标称截面(mm2)
        │ │ │ └───绞线
        │ │ └─────芯线为钢芯
        │ └──────包覆
        └────────铝
