電子計算機屏蔽電纜

一，電子計算機屏蔽電纜

是(shi)指(zhi)有(you)金屬絲(si)編織或金屬帶外(wai)包屏(ping)(ping)(ping)(ping)蔽(bi)層(ceng)，具(ju)有(you)電(dian)(dian)(dian)磁(ci)(ci)屏(ping)(ping)(ping)(ping)蔽(bi)性能的(de)(de)(de)電(dian)(dian)(dian)纜(lan)(lan)。適用(yong)于變壓器及類似需要屏(ping)(ping)(ping)(ping)蔽(bi)電(dian)(dian)(dian)磁(ci)(ci)信(xin)號的(de)(de)(de)設備(bei)用(yong)。電(dian)(dian)(dian)纜(lan)(lan)屏(ping)(ping)(ping)(ping)蔽(bi)是(shi)指(zhi)電(dian)(dian)(dian)纜(lan)(lan)外(wai)層(ceng)網狀編織線(xian)(xian)已單端接地,可以(yi)使(shi)外(wai)界電(dian)(dian)(dian)磁(ci)(ci)輻(fu)射(she)及磁(ci)(ci)場輻(fu)射(she)直接入地而對內層(ceng)電(dian)(dian)(dian)線(xian)(xian)不產生(sheng)干(gan)擾。一(yi)般(ban)用(yong)于頻率(lv)較高(gao)、信(xin)號電(dian)(dian)(dian)平比(bi)較低的(de)(de)(de)線(xian)(xian)路，如有(you)線(xian)(xian)電(dian)(dian)(dian)視，變頻器至電(dian)(dian)(dian)機(ji)(ji)引線(xian)(xian)要用(yong)，模擬量引線(xian)(xian)，以(yi)及一(yi)些有(you)干(gan)擾的(de)(de)(de)傳輸線(xian)(xian)路，如計算機(ji)(ji)屏(ping)(ping)(ping)(ping)蔽(bi)電(dian)(dian)(dian)纜(lan)(lan)等。只要是(shi)帶屏(ping)(ping)(ping)(ping)蔽(bi)層(ceng)的(de)(de)(de)電(dian)(dian)(dian)纜(lan)(lan)都稱為(wei)屏(ping)(ping)(ping)(ping)蔽(bi)電(dian)(dian)(dian)纜(lan)(lan)，電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)，控制(zhi)電(dian)(dian)(dian)纜(lan)(lan)都可以(yi)加屏(ping)(ping)(ping)(ping)蔽(bi)層(ceng)。計算機(ji)(ji)和儀表電(dian)(dian)(dian)纜(lan)(lan)一(yi)般(ban)都有(you)屏(ping)(ping)(ping)(ping)蔽(bi)層(ceng)，以(yi)防(fang)止外(wai)界電(dian)(dian)(dian)磁(ci)(ci)信(xin)號的(de)(de)(de)干(gan)擾。

用(yong)途：產(chan)品(pin)適用(yong)于發(fa)電(dian)(dian)、冶金、石化等(deng)工礦集散系統、電(dian)(dian)子記算機系統的信號傳輸及檢測(ce)儀器、儀表等(deng)連接用(yong)多對屏蔽電(dian)(dian)纜(lan)。導體長期允許工作溫(wen)度一般型70℃，型號后加105℃，不超過105℃。額定(ding)(ding)電(dian)(dian)壓：U。/U為300/500V。zui低環(huan)境溫(wen)度：固(gu)定(ding)(ding)敷設-40℃，非(fei)固(gu)定(ding)(ding)敷設-15℃。無(wu)裝鎧層電(dian)(dian)纜(lan)zui小(xiao)彎(wan)曲半徑應不小(xiao)于電(dian)(dian)纜(lan)外徑的6倍；有裝鎧層電(dian)(dian)纜(lan)zui小(xiao)彎(wan)曲半徑不小(xiao)于電(dian)(dian)纜(lan)外徑的12倍。

三，技術參數：

屏蔽層(ceng)接(jie)(jie)地(di)(di)通常(chang)采用以下(xia)兩(liang)種方(fang)式來處理：屏蔽層(ceng)單端接(jie)(jie)地(di)(di)和屏蔽層(ceng)雙端接(jie)(jie)地(di)(di)。??

②?雙(shuang)端(duan)接(jie)(jie)地(di)是(shi)將(jiang)屏蔽電纜的金屬屏蔽層的兩端(duan)均連接(jie)(jie)接(jie)(jie)地(di)。
