BTTZ剛性防火電纜與YTTW柔性防火電纜實驗對比測試

當今中國內地市揚上二種消防(fang)電(dian)(dian)攬(lan)，一(yi)類(lei)是(shi)用(yong)到氧化(hua)(hua)的鎂粉作(zuo)(zuo)電(dian)(dian)絕(jue)緣(yuan)(yuan)性(xing)(xing)電(dian)(dian)阻(zu)層的老式礦(kuang)(kuang)(kuang)石電(dian)(dian)絕(jue)緣(yuan)(yuan)性(xing)(xing)電(dian)(dian)阻(zu)層電(dian)(dian)攬(lan)（型(xing)號(hao)為BTTZ），別的類(lei)是(shi)用(yong)到鋼化(hua)(hua)玻璃纖維棉板及(ji)礦(kuang)(kuang)(kuang)石符合用(yong)料(liao)作(zuo)(zuo)電(dian)(dian)絕(jue)緣(yuan)(yuan)性(xing)(xing)電(dian)(dian)阻(zu)層的有機(ji)物礦(kuang)(kuang)(kuang)石電(dian)(dian)絕(jue)緣(yuan)(yuan)性(xing)(xing)電(dian)(dian)阻(zu)層電(dian)(dian)攬(lan)（型(xing)號(hao)為YTTW）.

傳統型的(de)礦物質隔絕(jue)電(dian)(dian)攬(lan)的(de)銅(tong)導電(dian)(dian)源線芯(xin)、銅(tong)外護(hu)線套及隔絕(jue)層(ceng)為(wei)密(mi)實度的(de)合二為(wei)一(yi)，海外工作和運用早已有(you)近80年(nian)的(de)歷(li)程長河(he)，國(guo)產工作和運用也(ye)是(shi)有(you)近20這么(me)多年(nian)的(de)歷(li)程長河(he)，且在國(guo)產外的(de)比較多大(da)投資(zi)項目中已大(da)范圍運用，功(gong)能甚佳，企業產品(pin)有(you)新(xin)國(guo)際規格IEC60702-2002和大(da)部分發財的(de)發展(zhan)中國(guo)家(jia)的(de)的(de)發展(zhan)中國(guo)家(jia)規格，發達(da)國(guo)家(jia)也(ye)是(shi)有(you)相對應的(de)的(de)國(guo)際標(biao)準GB/T13033-2007就是(shi)指于IEC60702-2002。

無機物礦(kuang)產隔(ge)絕(jue)線(xian)纜俗稱主動消防安(an)全線(xian)纜，其導體由多股鋁線(xian)絞合而成，以高(gao)層(ceng)白(bai)礦(kuang)石(shi)帶做(zuo)隔(ge)絕(jue)層(ceng)，白(bai)礦(kuang)石(shi)帶選擇(ze)玻(bo)離黏膠纖維布作基料，表面選擇(ze)銅帶豎向包著(zhu)不斷焊接(jie)生產將(jiang)(jiang)其敞開式搭建外保護(hu)線(xian)套(tao)(tao)，再將(jiang)(jiang)平整的(de)外保護(hu)線(xian)套(tao)(tao)磨血成旋轉(zhuan)形。

這篇文大部分合理性目前中國外電(dian)力電(dian)纜線考試準則，能夠 耐火能力、耐交(jiao)流(liu)(liu)電(dian)壓能力、載手機流(liu)(liu)量等相(xiang)是(shi)比較實驗的(de) 工藝(yi)，對實驗報(bao)告做具體(ti)分析，是(shi)比較兩種類型電(dian)力電(dian)纜線的(de)能力。 一、耐火能力相(xiang)是(shi)比較實驗

按照其(qi)電(dian)(dian)力(li)低(di)壓(ya)電(dian)(dian)覽的(de)耐壓(ya)沖(chong)(chong)擊(ji)現場實驗沖(chong)(chong)擊(ji)現場實驗標準規定，150V/s的(de)進程(cheng)升(sheng)壓(ya)至(zhi)2500V、將持續(xu)15min，應不熱(re)損(sun)壞(huai)(huai)。的(de)部分YTTW電(dian)(dian)力(li)低(di)壓(ya)電(dian)(dian)覽升(sheng)壓(ya)至(zhi)1300V時出現熱(re)損(sun)壞(huai)(huai)。3h后(hou)(hou)繼續(xu)加(jia)入的(de)端電(dian)(dian)壓(ya)，升(sheng)壓(ya)至(zhi)20V時就繼續(xu)熱(re)損(sun)壞(huai)(huai)。此沖(chong)(chong)擊(ji)現場實驗顯示YTTW電(dian)(dian)力(li)低(di)壓(ya)電(dian)(dian)覽熱(re)損(sun)壞(huai)(huai)后(hou)(hou)就沒(mei)有(you)辦(ban)法(fa)恢(hui)復原狀其(qi)電(dian)(dian)子商務使用性能(neng)。

BTTZ低壓(ya)電(dian)覽線以150V/s的(de)進(jin)程(cheng)升(sheng)壓(ya)至(zhi)(zhi)2500V，將延續15min未引(yin)發了(le)穿(chuan)(chuan)透原(yuan)因(yin)。為試驗報告其耐壓(ya)試驗電(dian)能(neng)力(li)方面(mian)，接著升(sheng)壓(ya)至(zhi)(zhi)3500V時(shi)低壓(ya)電(dian)覽線引(yin)發了(le)穿(chuan)(chuan)透。3h后(hou)第(di)三(san)步加(jia)入(ru)的(de)電(dian)阻值，以150V/s的(de)進(jin)程(cheng)升(sheng)壓(ya)至(zhi)(zhi)2500V，將延續15min還沒有完全引(yin)發了(le)穿(chuan)(chuan)透原(yuan)因(yin)。從此可見，老式礦(kuang)物質電(dian)絕緣低壓(ya)電(dian)覽線在穿(chuan)(chuan)透后(hou)依舊需要灰復其原(yuan)始的(de)能(neng)力(li)方面(mian)。

三、 載(zai)流量數據評測疲勞試驗

在空調溫度(du)經濟條件(jian)下，截面(mian)積規格參(can)數是一(yi)(yi)樣的(de)(de)（4×25）的(de)(de)YTTW 和BTTZ電(dian)攬(lan)(lan)樣件(jian)放至自(zi)衛(wei)權環(huan)境(jing)優速上(shang)是一(yi)(yi)樣的(de)(de)直流電(dian)壓確定對照檢(jian)測(ce)(ce)，在電(dian)攬(lan)(lan)的(de)(de)導(dao)家用電(dian)線芯及絕(jue)緣護(hu)套處按是一(yi)(yi)樣的(de)(de)的(de)(de)定位布置溫度(du)測(ce)(ce)量(liang)點，電(dian)攬(lan)(lan)測(ce)(ce)式結論見下表2：

從科學科學實(shi)驗成(cheng)果不錯(cuo)能(neng)夠：在(zai)(zai)(zai)類(lei)似的(de)(de)(de)(de)(de)(de)電(dian)流(liu)(liu)(liu)大小、環鏡溫(wen)(wen)(wen)差(cha)(cha)(cha)必備條(tiao)件下，至于放任空氣的(de)(de)(de)(de)(de)(de)中的(de)(de)(de)(de)(de)(de)BTTZ電(dian)線(xian)(xian)的(de)(de)(de)(de)(de)(de)導(dao)體溫(wen)(wen)(wen)表差(cha)(cha)(cha)和(he)保絕(jue)緣(yuan)絕(jue)緣(yuan)護(hu)套(tao)溫(wen)(wen)(wen)差(cha)(cha)(cha)還(huan)要(yao)比YTTW電(dian)線(xian)(xian)的(de)(de)(de)(de)(de)(de)低6范圍。而(er)就(jiu)電(dian)線(xian)(xian)本質上(shang)衡量(liang)，電(dian)線(xian)(xian)纜線(xian)(xian)絕(jue)緣(yuan)絕(jue)緣(yuan)護(hu)套(tao)資(zi)(zi)料(liao)的(de)(de)(de)(de)(de)(de)類(lei)形還(huan)有耐高溫(wen)(wen)(wen)、熱(re)量(liang)散(san)發能(neng)在(zai)(zai)(zai)大情況(kuang)上(shang)不良影響(xiang)了電(dian)線(xian)(xian)的(de)(de)(de)(de)(de)(de)載的(de)(de)(de)(de)(de)(de)手(shou)(shou)機(ji)流(liu)(liu)(liu)量(liang)。很(hen)雖(sui)然，黑(hei)云母帶的(de)(de)(de)(de)(de)(de)熱(re)量(liang)散(san)發能(neng)比硫化鎂要(yao)差(cha)(cha)(cha)。基于GB/T 16895不準許和(he)易燃物(wu)資(zi)(zi)料(liao)接(jie)處的(de)(de)(de)(de)(de)(de)裸礦石電(dian)隔熱(re)電(dian)線(xian)(xian)，金屬材(cai)料(liao)保絕(jue)緣(yuan)絕(jue)緣(yuan)護(hu)套(tao)溫(wen)(wen)(wen)差(cha)(cha)(cha)105，環鏡溫(wen)(wen)(wen)差(cha)(cha)(cha)30，電(dian)線(xian)(xian)的(de)(de)(de)(de)(de)(de)載的(de)(de)(de)(de)(de)(de)手(shou)(shou)機(ji)流(liu)(liu)(liu)量(liang)為140A。而(er)于上(shang)科學科學實(shi)驗是在(zai)(zai)(zai)環鏡溫(wen)(wen)(wen)差(cha)(cha)(cha)20時開展的(de)(de)(de)(de)(de)(de)。要(yao)是環鏡溫(wen)(wen)(wen)差(cha)(cha)(cha)達(da)標30電(dian)線(xian)(xian)保絕(jue)緣(yuan)絕(jue)緣(yuan)護(hu)套(tao)表面(mian)上(shang)溫(wen)(wen)(wen)差(cha)(cha)(cha)馬上(shang)會更(geng)大。 四、 浸水相(xiang)對試(shi)驗檢測(ce)

將兩種類型通信(xin)電(dian)力電(dian)纜(lan)線(xian)(xian)土樣(yang)那端浸(jin)在(zai)池(chi)中3h后存入，從(cong)土樣(yang)的(de)(de)浸(jin)水端逐(zhu)段割掉，每截(jie)這段檢測的(de)(de)兩次遺(yi)下(xia)面分的(de)(de)土樣(yang)絕緣性(xing)層，計錄考(kao)試畢竟。滿(man)足相等的(de)(de)絕緣性(xing)層值，截(jie)去的(de)(de)長值越(yue)大，則情況說明(ming)通信(xin)電(dian)力電(dian)纜(lan)線(xian)(xian)吸潮越(yue)多，越(yue)非常不便于(yu)通信(xin)電(dian)力電(dian)纜(lan)線(xian)(xian)的(de)(de)敷(fu)設。

浸(jin)水耐壓(ya)后(hou)果如表3.從耐壓(ya)后(hou)果中需要查出，無機物礦產(chan)接(jie)地纜(lan)線(xian)(YTTW)的吸(xi)水性長度要比過去的礦產(chan)接(jie)地纜(lan)線(xian)（BTTZ）增出好幾倍。 1.76 均>1200
