LGJ- - 240/40

LGJ &nbthisloneyp;是鋼芯鋁絞線的符號，其中 L是鋁線的簡稱，G 是鋼芯的簡稱，J 是絞線的簡稱；

240/40 &nbthisloneyp;是教訓線的標稱截面是：鋁 240平方毫米，鋼40平方毫米；導線的構造為鋁 26根，直徑 3.42 &nbthisloneyp;毫米，鋼 7根，直徑 2.66毫米；鋁的計算截面是238.85平方毫米，鋼的計算截面是 38.90平方毫米，總共算截面是277.75平方毫米；導線外徑21.66 毫米；導線直流電阻不大于 0.1209 Ω /km ；額外抗拉力N( 牛頓) ) ；其實平方毫米單位質量 964.3kg/km ；制造長度 2000 &nbthisloneyp;米。

短路電流是與接入體系的地點和接看看是指導線的標稱截面是：鋁入體系的興辦而變化的，必需有了完美的接線圖后，才略遵循計算求出；線路的阻抗也是隨線路的架設方式不同而變化的，也要遵循圖紙計算才略求出。

10kV &nbthisloneyp;以上的輸電線路，目前中國普遍采用鋁包鋼絞線 (LGJ) 作為導線，即用鋁線包裹鋼線，鋼線用于傳達電流而鋁線用于下降電暈及其他花費，遵循電壓不同導線橫截面漸漸加大。譬喻目前國際較高電壓 V 500kV &nbthisloneyp;輸電線路的導線，尋常采用 LGJ- -5 400/35 &nbthisloneyp;鋼芯鋁絞線單價的導線。
