電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)在(zai)工作(zuo)的(de)時候電(dian)(dian)阻會產生(sheng)熱量這是大(da)家(jia)都(dou)知道的(de)事實。電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)導(dao)(dao)線(xian)(xian)功率都(dou)非常小，發(fa)熱功率也有(you)專業(ye)公式可以計算出來：q=I^2R。Q=I^2R表(biao)示通過導(dao)(dao)體的(de)電(dian)(dian)流(liu)越(yue)大(da)，它(ta)的(de)加熱功率越(yue)大(da)（R基本上是恒定的(de)）;如果電(dian)(dian)流(liu)恒定，則導(dao)(dao)線(xian)(xian)的(de)發(fa)...

冬季嚴(yan)寒(han)，許(xu)多施工(gong)人員(yuan)在敷設安裝(zhuang)電(dian)(dian)線電(dian)(dian)纜(lan)的時候會發現，平時質量良好(hao)的電(dian)(dian)線電(dian)(dian)纜(lan)產(chan)品(pin)(pin)(pin)，經常(chang)(chang)(chang)會出(chu)現一些線體發硬、絕緣外皮脫落受損(sun)等現象(xiang)，很多施工(gong)人員(yuan)以為是(shi)電(dian)(dian)線電(dian)(dian)纜(lan)產(chan)品(pin)(pin)(pin)本(ben)身出(chu)現了質量問題，而電(dian)(dian)纜(lan)廠家也堅持產(chan)品(pin)(pin)(pin)在出(chu)廠時已經經過檢(jian)驗，是(shi)合格的產(chan)品(pin)(pin)(pin)，常(chang)(chang)(chang)常(chang)(chang)(chang)...
