電(dian)線電(dian)纜(lan)產品的外(wai)皮(pi)(pi)多為普通塑料(PVC)或(huo)橡膠，當他們處于零(ling)度以(yi)下(xia)的環境(jing)時，就(jiu)會變硬(ying)，整個電(dian)線電(dian)纜(lan)產品線體都(dou)會發硬(ying)、變脆(cui)，導致(zhi)外(wai)皮(pi)(pi)可能在輕微外(wai)力的情況下(xia)都(dou)會出現脫(tuo)落受損(sun)，在冬(dong)季，尤其是北(bei)方地(di)區，室(shi)(shi)外(wai)的溫度往往處于零(ling)度以(yi)下(xia)，地(di)表溫度可能會更低，所以(yi)，如果將電(dian)線電(dian)纜(lan)產品置于室(shi)(shi)外(wai)或(huo)直(zhi)接置于地(di)表，很可能就(jiu)會出現產品外(wai)皮(pi)(pi)脫(tuo)落的現象(xiang)。

而且也(ye)要看(kan)(kan)電(dian)(dian)(dian)(dian)纜本(ben)身是(shi)否有商標、規(gui)格、電(dian)(dian)(dian)(dian)壓等。還要看(kan)(kan)電(dian)(dian)(dian)(dian)線(xian)(xian)銅(tong)芯(xin)的(de)(de)(de)橫截面，的(de)(de)(de)紫(zi)銅(tong)顏色光亮、色澤(ze)柔和。2、稱(cheng)重(zhong)量(liang)(liang)(liang)。質量(liang)(liang)(liang)好的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)，一(yi)般都在規(gui)定的(de)(de)(de)重(zhong)量(liang)(liang)(liang)范(fan)圍內(nei)。比(bi)如常用的(de)(de)(de)截面積為(wei)1。5平方的(de)(de)(de)塑(su)料(liao)(liao)絕(jue)緣(yuan)(yuan)單股(gu)銅(tong)芯(xin)線(xian)(xian)，每(mei)100m重(zhong)量(liang)(liang)(liang)為(wei)1。8~1。9KG，2。5平方的(de)(de)(de)塑(su)料(liao)(liao)絕(jue)緣(yuan)(yuan)單股(gu)銅(tong)芯(xin)線(xian)(xian)，每(mei)100m的(de)(de)(de)重(zhong)量(liang)(liang)(liang)為(wei)3~3。1kg。質量(liang)(liang)(liang)差的(de)(de)(de)電(dian)(dian)(dian)(dian)纜重(zhong)量(liang)(liang)(liang)不足，要么長度不夠，要么電(dian)(dian)(dian)(dian)線(xian)(xian)的(de)(de)(de)銅(tong)芯(xin)雜質太多。

電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)防(fang)(fang)火(huo)(huo)措(cuo)施在(zai)日常生(sheng)活中，電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)是(shi)(shi)我們所必備的用(yong)品，家里的電(dian)(dian)(dian)(dian)器，綠寶(bao)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)(lan)，高壓電(dian)(dian)(dian)(dian)線(xian)等等，但(dan)是(shi)(shi)有一個很重要的問(wen)題(ti)，就是(shi)(shi)如何(he)防(fang)(fang)范電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的漏(lou)電(dian)(dian)(dian)(dian)，比(bi)如在(zai)火(huo)(huo)災中，電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)被(bei)火(huo)(huo)勢燒壞了外層(ceng)，那么線(xian)芯就直接裸2露在(zai)外，很可能(neng)會引(yin)發二次災害，所以電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的防(fang)(fang)火(huo)(huo)措(cuo)施必須要做好。電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)防(fang)(fang)火(huo)(huo)有哪些措(cuo)施?(1)采用(yong)阻燃電(dian)(dian)(dian)(dian)纜(lan)(lan);(2)采用(yong)防(fang)(fang)火(huo)(huo)電(dian)(dian)(dian)(dian)纜(lan)(lan)托架(jia)(jia);(3)采用(yong)防(fang)(fang)火(huo)(huo)涂料;(4)電(dian)(dian)(dian)(dian)纜(lan)(lan)隧(sui)道(dao)、夾(jia)層(ceng)出(chu)口(kou)等處(chu)設置防(fang)(fang)火(huo)(huo)隔(ge)墻(qiang)、防(fang)(fang)火(huo)(huo)擋(dang)板;(5)架(jia)(jia)空電(dian)(dian)(dian)(dian)纜(lan)(lan)應避開油管(guan)道(dao)、防(fang)(fang)爆門，否則(ze)應有要取部分穿管(guan)或隔(ge)熱防(fang)(fang)火(huo)(huo)措(cuo)施。
