礦物(wu)絕(jue)緣(yuan)電纜的四大優點

礦物絕緣電纜從結構上看不含(han)有(you)機材(cai)料，都(dou)是礦物化合物構成的絕緣層，因此具有(you)不燃(ran)燒(shao)、無yan、無危(wei)害、耐火等幾(ji)大(da)優點

一、耐火

一般來說，民(min)用建(jian)筑(zhu)火災(zai)現場(chang)(chang)溫度一般為1萬℃銅熔(rong)點為1083℃，礦(kuang)(kuang)物絕(jue)緣的熔(rong)點也是1萬℃，因此礦(kuang)(kuang)物絕(jue)緣電纜(lan)能夠火災(zai)現場(chang)(chang)高溫

二、耐高溫(wen)：礦物(wu)絕緣電纜連續(xu)工作溫(wen)度可(ke)達(da)250℃，當溫(wen)度達(da)到銅護套熔點時(shi)，仍然(ran)可(ke)以(yi)在(zai)短時(shi)間內維持工作，因此比較適合于冶(ye)金、鍋爐、玻璃爐窯、敷設高爐等場所

三(san)、穩定性好(hao)：礦物絕緣電纜用(yong)的是(shi)無機材料制成的絕緣層(ceng)，護套層(ceng)具(ju)有穩定性和使用(yong)壽命長的特點

四、高(gao)工藝更耐(nai)(nai)用：礦(kuang)物絕緣電纜絕緣層(ceng)采用高(gao)密度壓實(shi)工藝，外層(ceng)無縫銅護(hu)套層(ceng)保護(hu)，耐(nai)(nai)火(huo)、抗噴(pen)淋、抗機械沖擊，更耐(nai)(nai)用

確(que)測出電(dian)線電(dian)纜斷點(dian)的測量方(fang)法有哪些呢

1，萬用表檢測法：

    首先是(shi)把不通的(de)整根線(xian)纜(lan)(lan)(lan)一(yi)端接到強(qiang)電(dian)的(de)火(huo)線(xian)上，雙(shuang)橋礦(kuang)物絕緣電(dian)纜(lan)(lan)(lan)，另一(yi)端置空。把萬用表撥到AC2V檔上，礦(kuang)物絕緣電(dian)纜(lan)(lan)(lan)規范(fan)，從線(xian)纜(lan)(lan)(lan)接電(dian)端開始，一(yi)邊(bian)捏(nie)住(zhu)黑色(se)筆(bi)筆(bi)尖，一(yi)邊(bian)將紅色(se)筆(bi)沿著(zhu)導線(xian)的(de)絕緣皮(pi)慢慢移動，此(ci)時顯示(shi)屏顯示(shi)的(de)電(dian)壓值大約為0.445V左右(you)。

當紅表(biao)筆移(yi)動(dong)到(dao)某處時，顯示屏顯示的(de)(de)電壓突(tu)然下(xia)降到(dao)0.0幾伏，大(da)約是原來電壓的(de)(de)十分(fen)之一，從該位置向前（火線接入端）的(de)(de)大(da)約15cm處即是斷(duan)點(dian)所在。

2，感應(ying)式電筆檢測(ce)檢測(ce)法(fa)

    感應試(shi)電(dian)(dian)(dian)筆(bi)，就是(shi)帶著一個電(dian)(dian)(dian)子(zi)屏幕，可(ke)以檢測(ce)電(dian)(dian)(dian)壓和通斷(duan)的(de)設備。首先排除斷(duan)點(dian)電(dian)(dian)(dian)纜(lan)周圍的(de)電(dian)(dian)(dian)纜(lan)有電(dian)(dian)(dian)源，然(ran)后(hou)將(jiang)有斷(duan)點(dian)的(de)電(dian)(dian)(dian)纜(lan)接在火線(xian)上，將(jiang)電(dian)(dian)(dian)筆(bi)垂直于導線(xian)，按住“感應斷(duan)點(dian)測(ce)試(shi)”按鈕在導線(xian)上向前緩慢移動，等試(shi)電(dian)(dian)(dian)筆(bi)檢測(ce)的(de)交流信號出(chu)現突然(ran)消(xiao)失時，即可(ke)判(pan)斷(duan)斷(duan)點(dian)在該檢測(ce)點(dian)處，礦物絕緣電(dian)(dian)(dian)纜(lan)分支，誤差較多不超(chao)過10cm。

需(xu)要注意的是：斷(duan)點(dian)電(dian)(dian)(dian)線周圍的電(dian)(dian)(dian)纜(lan)不能帶有電(dian)(dian)(dian)源(yuan)。另外要提醒的是，短電(dian)(dian)(dian)纜(lan)效(xiao)果(guo)明顯，電(dian)(dian)(dian)纜(lan)越長效(xiao)果(guo)越不好。

3，使用音頻探測儀

    音頻探測儀是一種利用單頻或復頻信號，可測試線路的連續性，來識別線路故障的儀器。能在連接任何交換機、路由器、PC終端的情況下直接找線。在電纜線路時，無需剝開線路外皮，簡單、快捷，并可以判別線路斷點的位置。
