誰知道江蘇電線電纜粗好？還是細好？

買電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)的(de)(de)(de)時候，如(ru)果我們買了載(zai)流量(liang)較(jiao)小(xiao)的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)，接(jie)通(tong)功率較(jiao)大(da)(da)的(de)(de)(de)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)時，電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)就會發熱，容易(yi)引(yin)起漏電(dian)(dian)(dian)(dian)、過載(zai)，從而燒(shao)壞(huai)(huai)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)或(huo)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)，引(yin)起電(dian)(dian)(dian)(dian)路損壞(huai)(huai)。于是(shi)有人就說了，既(ji)然粗線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)阻更小(xiao)電(dian)(dian)(dian)(dian)流更大(da)(da)，能避免(mian)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)燒(shao)壞(huai)(huai)、短(duan)路、停電(dian)(dian)(dian)(dian)，那么家(jia)里(li)鋪設電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)時，都(dou)用粗線(xian)(xian)(xian)不就好了？理論(lun)上這是(shi)行(xing)得(de)通(tong)的(de)(de)(de)，但(dan)是(shi)也沒(mei)有這個必要。

一(yi)方面(mian)來(lai)講，電(dian)線越粗(cu)，可能(neng)比(bi)細電(dian)線要更(geng)加(jia)省電(dian)。因為較細的電(dian)線，它的電(dian)阻(zu)值(zhi)也(ye)(ye)會(hui)越大，通電(dian)的狀態(tai)之下，能(neng)夠(gou)產生(sheng)很大的熱(re)量(liang)，可能(neng)就會(hui)比(bi)較耗電(dian)。而粗(cu)的電(dian)線橫截(jie)面(mian)積較大，電(dian)阻(zu)值(zhi)就會(hui)比(bi)較小，負荷也(ye)(ye)會(hui)變小，相比(bi)較就會(hui)比(bi)較省電(dian)。

但(dan)是從(cong)另外一方面來看，電(dian)(dian)線(xian)(xian)越(yue)粗，價(jia)格可能就越(yue)貴。現(xian)在家里(li)常用大(da)功率電(dian)(dian)器(qi)：洗(xi)衣機、空調、冰箱、電(dian)(dian)磁爐……這些電(dian)(dian)器(qi)的瓦數(shu)我們都可以得知，用“功率÷220V”，就可以得出(chu)電(dian)(dian)器(qi)電(dian)(dian)流(liu)大(da)小(xiao)，根據電(dian)(dian)流(liu)選擇電(dian)(dian)線(xian)(xian)，沒有必要(yao)再買(mai)更(geng)(geng)粗、更(geng)(geng)貴的電(dian)(dian)線(xian)(xian)。
