母(mu)線(xian)(xian)(xian)是(shi)(shi)在高(gao)低(di)壓變配(pei)電(dian)(dian)裝置中(zhong)(zhong)作為(wei)配(pei)電(dian)(dian)母(mu)線(xian)(xian)(xian)的，是(shi)(shi)在電(dian)(dian)鍍(du)車間中(zhong)(zhong)作為(wei)低(di)壓載流母(mu)線(xian)(xian)(xian)的，是(shi)(shi)在大(da)型車間中(zhong)(zhong)作為(wei)配(pei)電(dian)(dian)干線(xian)(xian)(xian)的，可說是(shi)(shi)電(dian)(dian)流的匯集(ji)線(xian)(xian)(xian)，軟母(mu)線(xian)(xian)(xian)的外徑用(yong)導(dao)線(xian)(xian)(xian)直徑的組合號(hao)表示(shi)，則組合號(hao)與D的關(guan)系(xi).

MDG母(mu)線(xian)固(gu)定金具宣(xuan)稱電廠金具或(huo)是大電流母(mu)線(xian)金具，它即是固定或(huo)連接于配電裝置中的各(ge)種硬母(mu)線(xian)或(huo)軟母(mu)線(xian)與支柱絕緣子等.

大(da)部分固定金具(ju)不(bu)作為導電體，僅起固定、支持、懸(xuan)吊的作用(yong)，但由于(yu)這些金具(ju)是(shi)用(yong)于(yu)大(da)電流，故所有(you)元件均應無磁滯(zhi)損失。
