正確選擇(ze)電(dian)(dian)線電(dian)(dian)纜(lan)非常重(zhong)要，怎樣選擇(ze)電(dian)(dian)線電(dian)(dian)纜(lan)是很(hen)多(duo)客戶咨詢的(de)問題，一起來學習(xi)一下：

首(shou)先，選(xuan)用(yong)(yong)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)產品(pin)時，最好請教有(you)經驗的(de)(de)專業電(dian)(dian)(dian)工，根據(ju)自己(ji)的(de)(de)用(yong)(yong)電(dian)(dian)(dian)負荷來采(cai)用(yong)(yong)合適截面大小和電(dian)(dian)(dian)壓等(deng)級的(de)(de)電(dian)(dian)(dian)纜(lan)。長(chang)度和截面是(shi)一(yi)個重要(yao)(yao)因(yin)素，合格證(zheng)上(shang)都(dou)有(you)長(chang)度標識，可先估算一(yi)下(xia)(xia)成品(pin)包裝的(de)(de)一(yi)圈線的(de)(de)長(chang)度，再(zai)數一(yi)下(xia)(xia)線盤的(de)(de)圈數，估出(chu)整卷線的(de)(de)大概長(chang)度，此外(wai)還要(yao)(yao)注意導體的(de)(de)直徑，看(kan)(kan)電(dian)(dian)(dian)纜(lan)的(de)(de)長(chang)度和截面。還要(yao)(yao)看(kan)(kan)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)外(wai)觀和材質，電(dian)(dian)(dian)線外(wai)層(ceng)塑料(liao)皮色澤鮮(xian)亮、質地細密(mi)，表(biao)面是(shi)否有(you)毛刺或(huo)突起(qi)，外(wai)觀是(shi)否光滑、圓整、色澤均勻，導體使用(yong)(yong)電(dian)(dian)(dian)解(jie)銅，外(wai)層(ceng)光亮而稍(shao)軟。再(zai)看(kan)(kan)一(yi)下(xia)(xia)電(dian)(dian)(dian)纜(lan)的(de)(de)截面，銅（鋁）芯(xin)應處于中(zhong)間(jian)，塑料(liao)層(ceng)厚薄應均勻。

產(chan)(chan)品(pin)(pin)(pin)的(de)標(biao)識也(ye)是(shi)重要的(de)一(yi)點，選(xuan)購(gou)電(dian)(dian)線電(dian)(dian)纜產(chan)(chan)品(pin)(pin)(pin)時應(ying)觀察(cha)產(chan)(chan)品(pin)(pin)(pin)的(de)合格證對于產(chan)(chan)品(pin)(pin)(pin)型號、規格、額定(ding)(ding)電(dian)(dian)壓、芯數、生產(chan)(chan)日期、執行標(biao)準、許(xu)可證編號等相(xiang)關(guan)信息是(shi)否(fou)標(biao)注(zhu)齊全，產(chan)(chan)品(pin)(pin)(pin)實物(wu)表面應(ying)印有廠名、產(chan)(chan)品(pin)(pin)(pin)型號和(he)額定(ding)(ding)電(dian)(dian)壓的(de)連續(xu)性標(biao)志，核實兩者相(xiang)關(guan)的(de)信息是(shi)否(fou)一(yi)致。
