電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)識別的(de)(de)小(xiao)(xiao)技巧1。電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)絕緣(yuan)層不是(shi)采(cai)用(yong)(yong)絕緣(yuan)塑料(liao)所制，而是(shi)用(yong)(yong)回收塑料(liao)制成(cheng)，電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)一米多(duo)少錢(qian)，輕輕一剝就能將絕緣(yuan)層剝開(kai)，這(zhe)樣極易造(zao)成(cheng)絕緣(yuan)層被電(dian)(dian)(dian)(dian)(dian)流(liu)擊(ji)而穿漏電(dian)(dian)(dian)(dian)(dian)，對使(shi)用(yong)(yong)者的(de)(de)生命財產安全造(zao)成(cheng)極大(da)威(wei)脅。2。導(dao)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)芯(xin)直流(liu)電(dian)(dian)(dian)(dian)(dian)阻(zu)不合格。電(dian)(dian)(dian)(dian)(dian)線(xian)導(dao)體的(de)(de)粗細、優(you)劣(lie)決定(ding)了電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)對電(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)負(fu)載量，如(ru)果電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)線(xian)芯(xin)采(cai)用(yong)(yong)劣(lie)質的(de)(de)材料(liao)、實際截面遠(yuan)遠(yuan)小(xiao)(xiao)于其所標(biao)明的(de)(de)規格，什么牌子的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)好，長(chang)期使(shi)用(yong)(yong)因導(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)過大(da)會造(zao)成(cheng)發熱，引(yin)起電(dian)(dian)(dian)(dian)(dian)器火災的(de)(de)危險。

我們知道現(xian)在生活(huo)離(li)不開電(dian)(dian)(dian)(dian)(dian)(dian)(dian)當(dang)然就(jiu)離(li)不開電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，由于(yu)使用(yong)場(chang)合的(de)不同對于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)選(xuan)用(yong)也(ye)是有區別的(de)，高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，變頻電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)，阻燃電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)等等，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan).價錢，這些不同特性(xing)(xing)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)應用(yong)場(chang)所(suo)有所(suo)不同。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)品(pin)種(zhong)非(fei)常多，性(xing)(xing)能要(yao)求(qiu)特別高(gao)，如導體用(yong)銅，要(yao)求(qiu)銅的(de)純度要(yao)在99。95%以(yi)上，有的(de)產(chan)品(pin)要(yao)采用(yong)無氧高(gao)純銅。我們對于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)挑(tiao)選(xuan)非(fei)常的(de)嚴(yan)謹，因為如果稍微(wei)不慎可能會造(zao)成安全事故(gu)。所(suo)以(yi)一旦電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)出(chu)現(xian)什么異常，蕪湖電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線，一定要(yao)及時的(de)找出(chu)原因并解決(jue)。

購(gou)買(mai)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)時(shi)怎樣鑒別優(you)劣呢？一(yi)要看(kan)：看(kan)有無(wu)質量體系認(ren)1證書；看(kan)合格證是(shi)否規(gui)范；看(kan)有無(wu)廠(chang)名、廠(chang)址、檢驗(yan)章、生產日(ri)期；看(kan)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)上(shang)是(shi)否印(yin)有商(shang)標、規(gui)格、電(dian)(dian)(dian)(dian)壓等(deng)。還(huan)要看(kan)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)銅(tong)芯的(de)橫斷面，優(you)等(deng)品(pin)紫銅(tong)顏色光亮(liang)、色澤柔和，否則便是(shi)次品(pin)。二要試：可取一(yi)根電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)頭用(yong)手(shou)反(fan)復彎曲，凡(fan)是(shi)手(shou)感柔軟、抗(kang)1疲勞強(qiang)度好(hao)、塑(su)料或橡膠手(shou)感彈性大且電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)絕緣體上(shang)無(wu)裂痕的(de)就是(shi)優(you)等(deng)品(pin)。電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)是(shi)用(yong)戶在用(yong)電(dian)(dian)(dian)(dian)過程中的(de)材料，其(qi)質量的(de)好(hao)壞(huai)，直接關系到千家萬戶的(de)用(yong)電(dian)(dian)(dian)(dian)安全。因(yin)此，在購(gou)買(mai)或選(xuan)用(yong)時(shi)，如何快速、準確檢查電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)質量的(de)好(hao)壞(huai)，是(shi)廣大電(dian)(dian)(dian)(dian)工必須掌握(wo)的(de)技能。
