電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜產(chan)(chan)(chan)(chan)品(pin)的(de)(de)(de)外(wai)皮多為(wei)普通塑料（PVC）或橡膠，當(dang)他們處于零度以下的(de)(de)(de)環境時(shi)(shi)，就(jiu)會變(bian)(bian)硬，整個電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜產(chan)(chan)(chan)(chan)品(pin)線(xian)(xian)體都會發(fa)硬、變(bian)(bian)脆，合肥電(dian)(dian)(dian)纜，導致外(wai)皮可能在(zai)輕(qing)微外(wai)力的(de)(de)(de)情(qing)況下都會出現脫落受損。在(zai)寒冷的(de)(de)(de)冬季，電(dian)(dian)(dian)纜廠(chang)(chang)家排(pai)名，產(chan)(chan)(chan)(chan)品(pin)出廠(chang)(chang)裝(zhuang)載到運(yun)輸工具(ju)上(shang)時(shi)(shi)，需要(yao)保暖(nuan)及保護(hu)措施。比如使用封閉的(de)(de)(de)運(yun)輸工具(ju)，防(fang)止產(chan)(chan)(chan)(chan)品(pin)直接(jie)暴露在(zai)外(wai)；給產(chan)(chan)(chan)(chan)品(pin)墊上(shang)一層軟墊子，如被褥或者其它較軟的(de)(de)(de)泡(pao)沫(mo)等(deng)；裝(zhuang)載時(shi)(shi)輕(qing)拿(na)輕(qing)放(fang)(fang)，切勿粗暴裝(zhuang)貨，同時(shi)(shi)避免產(chan)(chan)(chan)(chan)品(pin)出現彎曲(qu)過(guo)大。存(cun)(cun)放(fang)(fang)時(shi)(shi)建議將(jiang)產(chan)(chan)(chan)(chan)品(pin)置于室內存(cun)(cun)放(fang)(fang)，同時(shi)(shi)在(zai)存(cun)(cun)放(fang)(fang)的(de)(de)(de)地表上(shang)鋪上(shang)一層隔離層，電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜制造(zao)廠(chang)(chang)家，如木板、被褥、泡(pao)沫(mo)等(deng)等(deng)，防(fang)止產(chan)(chan)(chan)(chan)品(pin)受凍(dong)受潮，注意防(fang)止產(chan)(chan)(chan)(chan)品(pin)與(yu)地面直接(jie)接(jie)觸將(jiang)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜外(wai)皮刮傷(shang)的(de)(de)(de)現象，輕(qing)拿(na)輕(qing)放(fang)(fang)。

而(er)劣質電線(xian)(xian)用(yong)手能撕下或(huo)掐下來一塊(kuai)；5。看燃燒。按規定電線(xian)(xian)電纜的(de)(de)(de)絕(jue)緣層(ceng)(ceng)都具有(you)(you)一定的(de)(de)(de)阻(zu)燃性。剝下一段(duan)絕(jue)緣層(ceng)(ceng)，用(yong)打火機進(jin)行點燃，離開(kai)明(ming)火后能繼續自燃的(de)(de)(de)是(shi)劣質線(xian)(xian)。6。驗厚度。截取(qu)一段(duan)絕(jue)緣層(ceng)(ceng)，看絕(jue)緣層(ceng)(ceng)的(de)(de)(de)斷(duan)面是(shi)否有(you)(you)肉眼(yan)可見的(de)(de)(de)氣孔，其線(xian)(xian)芯是(shi)否位于絕(jue)緣層(ceng)(ceng)的(de)(de)(de)正(zheng)中。不居中的(de)(de)(de)是(shi)因為工藝不高而(er)造(zao)成的(de)(de)(de)偏芯現(xian)象，有(you)(you)氣孔說明(ming)使用(yong)的(de)(de)(de)絕(jue)緣料(liao)不合格。
