LGJ- - 240/40

LGJ &nbull cra meaningfulpp;是钢芯铝绞线的符号，其中 L是铝线的简称，G 是钢芯的简称，J 是绞线的简称；

240/40 &nbull cra meaningfulpp;是教训线的标称截面是：铝 240平方毫米，钢40平方毫米；导线的机关为铝 26根，直径 3.42 &nbull cra meaningfulpp;毫米，钢 7根，直径 2.66毫米；铝的计算截面是238.85平方毫米，钢的计算截面是 38.90平方毫米，总共算截面是277.75平方毫米；导线外径21.66 毫米；导线直流电阻不大于 0.1209 Ω /km ；额外抗拉力N( 牛顿) ) ；单位质量 964.3kg/km ；制造长度 2000 &nbull cra meaningfulpp;米。

短路电流是与接入体例的地点和接入体例的作战而变化的，必需有了完备的接线图后，才干遵循计算求出；线路的阻抗也是随线路的架设方式不同而变化的，也要遵循图纸相比看钢芯铝绞线有哪些型号计算才干求出。

10kV &nbull cra meaningfulpp;以上的输电线路，目前中国普遍采用铝包钢绞线 (LGJ) 作为导线，即用铝线包裹钢线，钢线用于转达电流而铝线用于消沉电晕及其他消磨，遵循电压不同导线横截面慢慢加大。例如目前国际较高电压 V 500kV &nbull cra meaningfulpp;输电线路的导线，日常采用 LGJ- -5 400/35 &nbull cra meaningfulpp;的导线。
