保障電(dian)纜(lan)設(she)備(bei)安全的(de)重(zhong)要(yao)性(xing)(xing)電(dian)纜(lan)設(she)備(bei)具有傳(chuan)輸容量大、損耗小、靈活性(xing)(xing)高、占地空間(jian)小、無污染等(deng)顯著優(you)點，近年來(lai)隨著我國國民經濟的(de)高速(su)發(fa)展，電(dian)纜(lan)設(she)備(bei)需求急(ji)劇增長，特別(bie)是(shi)迅猛發(fa)展的(de)大城市(shi)和城市(shi)密集居住(zhu)地區(qu)。電(dian)纜(lan)設(she)備(bei)的(de)安全性(xing)(xing)是(shi)保證電(dian)纜(lan)設(she)備(bei)運行安全的(de)重(zhong)要(yao)手段，也是(shi)電(dian)纜(lan)設(she)備(bei)實用化過程中需要(yao)重(zhong)點解決(jue)的(de)關鍵問題。因此(ci)，如何保障電(dian)纜(lan)設(she)備(bei)的(de)安全性(xing)(xing)具有十(shi)分重(zhong)要(yao)的(de)理論和現實意義(yi)。

冬(dong)季電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)損(sun)傷的(de)原因(yin)及預防(fang)措(cuo)施冬(dong)季嚴寒(han)，許多施工(gong)人(ren)員在敷設安裝電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)時候會(hui)發現，平時質量(liang)良好(hao)的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)產(chan)品(pin)，經常會(hui)出(chu)(chu)現一些線體發硬、絕(jue)緣外皮脫落(luo)受損(sun)等現象(xiang)，高溫(wen)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)廠，很多施工(gong)人(ren)員以為是(shi)(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)產(chan)品(pin)本身出(chu)(chu)現了質量(liang)問題(ti)，電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)多少錢，而(er)電(dian)(dian)(dian)(dian)纜(lan)廠家也堅持產(chan)品(pin)在出(chu)(chu)廠時已經經過(guo)檢驗，是(shi)(shi)合格的(de)產(chan)品(pin)，常常導致(zhi)雙方之(zhi)間的(de)誤會(hui)。其實，不(bu)是(shi)(shi)產(chan)品(pin)本身質量(liang)出(chu)(chu)了什么(me)問題(ti)，而(er)是(shi)(shi)由于(yu)冬(dong)季嚴寒(han)所致(zhi)。

購(gou)買電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)時(shi)怎樣鑒別(bie)優劣呢(ni)？一要看：看有無質(zhi)(zhi)(zhi)量體系認1證(zheng)(zheng)書(shu)；看合(he)格(ge)證(zheng)(zheng)是否(fou)規范；看有無廠(chang)名、廠(chang)址(zhi)、檢驗章、生產(chan)日(ri)期(qi)；看電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)上是否(fou)印有商標、規格(ge)、電(dian)(dian)(dian)(dian)壓等(deng)。還(huan)要看電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)銅芯的(de)(de)橫斷面，優等(deng)品(pin)紫銅顏色(se)光亮、色(se)澤柔和，否(fou)則便(bian)是次(ci)品(pin)。二(er)要試：可取一根電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)頭(tou)用(yong)(yong)手(shou)反復彎(wan)曲，安徽電(dian)(dian)(dian)(dian)線(xian)，凡是手(shou)感柔軟(ruan)、抗(kang)1疲勞強度好、塑料(liao)或橡膠手(shou)感彈性大(da)且電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)絕(jue)緣體上無裂痕的(de)(de)就(jiu)是優等(deng)品(pin)。電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)是用(yong)(yong)戶在用(yong)(yong)電(dian)(dian)(dian)(dian)過程中(zhong)的(de)(de)材料(liao)，其質(zhi)(zhi)(zhi)量的(de)(de)好壞，直接關系到千家(jia)萬戶的(de)(de)用(yong)(yong)電(dian)(dian)(dian)(dian)安全。因(yin)此(ci)，電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)，在購(gou)買或選用(yong)(yong)時(shi)，如何快速、準確檢查電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)質(zhi)(zhi)(zhi)量的(de)(de)好壞，是廣大(da)電(dian)(dian)(dian)(dian)工必須掌握的(de)(de)技能。
