由于線纜(lan)機械(xie)電(dian)力(li)電(dian)纜(lan)外徑較大，運輸、敷(fu)設較為困難，電(dian)力(li)電(dian)纜(lan)對(dui)轉彎半徑的要求也比較嚴(yan)格。電(dian)力(li)電(dian)纜(lan)在施(shi)工(gong)中，如(ru)果轉彎角(jiao)度過大，可能使導體內部受到(dao)機械(xie)損(sun)傷，而機械(xie)損(sun)傷因被電(dian)纜(lan)絕緣強度下降，直到(dao)出現故(gu)(gu)障(zhang)，施(shi)工(gong)中發(fa)現一次電(dian)纜(lan)頭故(gu)(gu)障(zhang)，在電(dian)纜(lan)頭制(zhi)作時，...
