style="text-indent:25px">廣義的電線電纜亦簡稱為電纜。狹義的電纜是指絕緣電纜。它可定義為：由下列部分組成的**體，一根或多根絕緣線芯，以及它們各自可能具有的包覆層，總保護層及外護層。電纜亦可有附加的沒有絕緣的導體。我國的電線電纜產(chǎn)品按其用途分成下列五大類： 1.裸電線； 2.繞組線； 3.電力電纜； 4.通信電纜和通信光纜； 5.電氣裝備用電線電纜。電線電纜的基本結(jié)構(gòu)： 1.導體：傳導電流的物體,電線電纜的規(guī)格都以導體的截面表示。 2.絕緣：外層絕緣材料按其耐受電壓程度。</p><p style="text-indent:25px">超負荷運行，由于電流的熱效應(yīng)，負載電流通過電纜時必然導致導體發(fā)熱，同時電荷的集膚效應(yīng)以及鋼鎧的渦流損耗、絕緣介質(zhì)損耗也會產(chǎn)乍附加熱量，從而使電纜溫度升高。長期超負荷運行時，過高的溫度會加速絕緣的老化，以至絕緣被擊穿。尤其在炎熱的夏季，電纜的溫升常常導致電纜絕緣薄弱處首先被擊穿，因此在夏季，電纜的故障也就特別多。電纜接頭是電纜線路中蕞薄弱的環(huán)節(jié)，由人員直接過失(施工不良)引發(fā)的電纜接頭故障時常發(fā)生。施工人員在制作電纜接頭過程中，如果有接頭壓接不緊、加熱不充分等原網(wǎng)，都會導致電纜頭絕緣降低，從而引發(fā)事故。</p><div

style="text-indent:25px">例如鋁芯絕緣線，環(huán)境溫度為不大于25℃時的載流量的計算：當截面為6平方毫米時，算得載流量為30安；當截面為150平方毫米時，算得載流量為300安；當截面為70平方毫米時，算得載流量為175安；從上面的排列還可以看出：倍數(shù)隨截面的增大而減小，在倍數(shù)轉(zhuǎn)變的交界處，誤差稍大些。比如截面25與35是四倍與三倍的分界處，25屬四倍的范圍，它按口訣算為100安，但按手冊為97安；而35則相反，按口訣算為105安，但查表為117安。不過這對使用的影響并不大。當然，若能“胸中有數(shù)”，在選擇導線截面時，25的不讓它滿到100安，35的則可略為超過105安便更準確了。同樣，2.5平方毫米的導線位置在五倍的始端，實際便不止五倍（比較大可達到20安以上），不過為了減少導線內(nèi)的電能損耗，通常電流都不用到這么大，手冊中一般只標12安。德陽電線電纜銷售</p><p
