一、銅(tong)(tong)絲(si)：這是采用的最(zui)為(wei)多的原料(liao)，沒有(you)之一。采用電(dian)(dian)解銅(tong)(tong)作(zuo)為(wei)原料(liao)，經連(lian)鑄連(lian)軋工藝制(zhi)成的的銅(tong)(tong)線(xian)(xian)稱(cheng)為(wei)低氧銅(tong)(tong)線(xian)(xian)；經上引法制(zhi)成的銅(tong)(tong)線(xian)(xian)稱(cheng)為(wei)無氧銅(tong)(tong)線(xian)(xian)。二、鋁線(xian)(xian)：這是由于(yu)銅(tong)(tong)價逐年上升，銅(tong)(tong)電(dian)(dian)纜(lan)制(zhi)造(zao)成本用作(zuo)電(dian)(dian)線(xian)(xian)用的鋁線(xian)(xian)都要進行退火軟化過(guo)。用作(zuo)電(dian)(dian)纜(lan)用的鋁線(xian)(xian)一般不(bu)...

一、在(zai)(zai)對線纜(lan)(lan)進行存放(fang)的時候，嚴禁與酸、堿及礦物油(you)類接觸,要與這些有(you)腐蝕(shi)性(xing)的物質隔離存放(fang)；二、貯存電(dian)(dian)纜(lan)(lan)的庫房內不(bu)得有(you)破壞絕緣及腐蝕(shi)金(jin)屬的有(you)害(hai)氣(qi)體(ti)存在(zai)(zai)；三、盡可能避(bi)免在(zai)(zai)露(lu)(lu)天以裸露(lu)(lu)方(fang)式存放(fang)電(dian)(dian)纜(lan)(lan)，電(dian)(dian)纜(lan)(lan)盤不(bu)允許平放(fang)；四、電(dian)(dian)纜(lan)(lan)在(zai)(zai)保管期...

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜在(zai)工作的(de)時候電(dian)(dian)(dian)阻(zu)會產生熱量這(zhe)是大家都知(zhi)道的(de)事實。電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)導線功率都非常小(xiao)，發熱功率也有專業(ye)公式(shi)可(ke)以計算出來：q=I^2R。Q=I^2R表示通(tong)過導體(ti)的(de)電(dian)(dian)(dian)流(liu)越(yue)大，它的(de)加熱功率越(yue)大（R基本(ben)上是恒定(ding)的(de)）;如果電(dian)(dian)(dian)流(liu)恒定(ding)，則導線的(de)發...
