6、用(yong)(yong)途:應用(yong)(yong)于樓(lou)宇自動(dong)化控制(zhi)系(xi)(xi)統(tong)、防盜報(bao)警(jing)系(xi)(xi)統(tong)、消防系(xi)(xi)統(tong)、三表自抄系(xi)(xi)統(tong)、通信、音(yin)頻、音(yin)響(xiang)系(xi)(xi)統(tong)、儀表、電(dian)子(zi)設備(bei)及自動(dong)化裝(zhuang)置(zhi)等需防干(gan)擾線(xian)路(lu)的(de)連接(jie)。
二、RVV線使用特性:(1)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)額定(ding)電(dian)(dian)(dian)壓(ya)(ya)(ya)Uo/U(相(xiang)電(dian)(dian)(dian)壓(ya)(ya)(ya)/線電(dian)(dian)(dian)壓(ya)(ya)(ya))為300/300V。當用于直流系(xi)統(tong)時(shi),該系(xi)統(tong)的(de)(de)標稱(cheng)電(dian)(dian)(dian)壓(ya)(ya)(ya)應不(bu)大于電(dian)(dian)(dian)纜(lan)(lan)額定(ding)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)1.5倍(bei)。注意,系(xi)統(tong)的(de)(de)工作電(dian)(dian)(dian)壓(ya)(ya)(ya)允(yun)許長(chang)時(shi)間(jian)的(de)(de)超過(guo)該系(xi)統(tong)標稱(cheng)電(dian)(dian)(dian)壓(ya)(ya)(ya)的(de)(de)10%,如果電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)額定(ding)電(dian)(dian)(dian)壓(ya)(ya)(ya)至少(shao)等于該系(xi)統(tong)的(de)(de)標稱(cheng)電(dian)(dian)(dian)壓(ya)(ya)(ya),則電(dian)(dian)(dian)纜(lan)(lan)可在高于額定(ding)電(dian)(dian)(dian)壓(ya)(ya)(ya)10%的(de)(de)工作電(dian)(dian)(dian)壓(ya)(ya)(ya)下使用。(2)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)長(chang)期允(yun)許工作溫(wen)度(du)應不(bu)超過(guo)70℃。
三(san)、網(wang)線(xian)(xian)采用了(le)一(yi)(yi)對(dui)互(hu)相絕緣(yuan)的(de)(de)(de)金屬導線(xian)(xian)互(hu)相絞(jiao)(jiao)(jiao)(jiao)合的(de)(de)(de)方(fang)(fang)式來(lai)抵御一(yi)(yi)部分外界電磁波干擾(rao)。把兩(liang)根(gen)絕緣(yuan)的(de)(de)(de)銅導線(xian)(xian)按一(yi)(yi)定(ding)密度(du)互(hu)相絞(jiao)(jiao)(jiao)(jiao)在一(yi)(yi)起,可以(yi)降低(di)信(xin)(xin)號干擾(rao)的(de)(de)(de)程度(du),每(mei)一(yi)(yi)根(gen)導線(xian)(xian)在傳(chuan)輸(shu)(shu)中輻射(she)的(de)(de)(de)電波會被另一(yi)(yi)根(gen)線(xian)(xian)上發出的(de)(de)(de)電波抵消。“雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)”的(de)(de)(de)名字也(ye)是(shi)由(you)此而來(lai)。雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)一(yi)(yi)般由(you)兩(liang)根(gen)22-26號絕緣(yuan)銅導線(xian)(xian)相互(hu)纏繞(rao)而成,實際使用時(shi),雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)是(shi)由(you)多對(dui)雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)一(yi)(yi)起包在一(yi)(yi)個(ge)絕緣(yuan)電纜(lan)套管里的(de)(de)(de)。典型(xing)的(de)(de)(de)雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)有四(si)對(dui)的(de)(de)(de),也(ye)有更多對(dui)雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)放在一(yi)(yi)個(ge)電纜(lan)套管里的(de)(de)(de)。這些我們稱(cheng)之為(wei)雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)電纜(lan)。在雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)電纜(lan)(也(ye)稱(cheng)雙(shuang)(shuang)(shuang)扭(niu)線(xian)(xian)電纜(lan))內(nei),不(bu)同(tong)(tong)線(xian)(xian)對(dui)具有不(bu)同(tong)(tong)的(de)(de)(de)扭(niu)絞(jiao)(jiao)(jiao)(jiao)長度(du),一(yi)(yi)般地說,扭(niu)絞(jiao)(jiao)(jiao)(jiao)長度(du)在38.1cm至14cm內(nei),按逆時(shi)針方(fang)(fang)向扭(niu)絞(jiao)(jiao)(jiao)(jiao)。相臨線(xian)(xian)對(dui)的(de)(de)(de)扭(niu)絞(jiao)(jiao)(jiao)(jiao)長度(du)在12.7cm以(yi)上,一(yi)(yi)般扭(niu)線(xian)(xian)的(de)(de)(de)越密其(qi)抗(kang)干擾(rao)能力就越強,與其(qi)他(ta)傳(chuan)輸(shu)(shu)介(jie)質相比(bi),雙(shuang)(shuang)(shuang)絞(jiao)(jiao)(jiao)(jiao)線(xian)(xian)在傳(chuan)輸(shu)(shu)距離,信(xin)(xin)道(dao)寬度(du)和數(shu)據傳(chuan)輸(shu)(shu)速度(du)等方(fang)(fang)面均(jun)受(shou)到一(yi)(yi)定(ding)限制(zhi),但價(jia)格較為(wei)低(di)廉。
