LGJ- - 240/40

LGJ &nbull cra meaningfulpp;是鋼芯鋁絞線的符號(hào)，其中 L是鋁線的簡(jiǎn)稱，G 是鋼芯的簡(jiǎn)稱，J 是絞線的簡(jiǎn)稱；

240/40 &nbull cra meaningfulpp;是教訓(xùn)線的標(biāo)稱截面是：鋁 240平方毫米，鋼40平方毫米；導(dǎo)線的機(jī)關(guān)為鋁 26根，直徑 3.42 &nbull cra meaningfulpp;毫米，鋼 7根，直徑 2.66毫米；鋁的計(jì)算截面是238.85平方毫米，鋼的計(jì)算截面是 38.90平方毫米，總共算截面是277.75平方毫米；導(dǎo)線外徑21.66 毫米；導(dǎo)線直流電阻不大于 0.1209 Ω /km ；額外抗拉力N( 牛頓) ) ；單位質(zhì)量 964.3kg/km ；制造長(zhǎng)度 2000 &nbull cra meaningfulpp;米。

短路電流是與接入體例的地點(diǎn)和接入體例的作戰(zhàn)而變化的，必需有了完備的接線圖后，才干遵循計(jì)算求出；線路的阻抗也是隨線路的架設(shè)方式不同而變化的，也要遵循圖紙相比看鋼芯鋁絞線有哪些型號(hào)計(jì)算才干求出。

10kV &nbull cra meaningfulpp;以上的輸電線路，目前中國普遍采用鋁包鋼絞線 (LGJ) 作為導(dǎo)線，即用鋁線包裹鋼線，鋼線用于轉(zhuǎn)達(dá)電流而鋁線用于消沉電暈及其他消磨，遵循電壓不同導(dǎo)線橫截面慢慢加大。例如目前國際較高電壓 V 500kV &nbull cra meaningfulpp;輸電線路的導(dǎo)線，日常采用 LGJ- -5 400/35 &nbull cra meaningfulpp;的導(dǎo)線。
