金環宇電線電纜分享電線穿管要點

    并不是所有電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)都要穿管你知道嗎(ma)，電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)型號有很多種，但是只有四種可以(yi)用(yong)于家庭——BV線(xian)(xian)(xian)(xian)(xian)(xian)、BVR線(xian)(xian)(xian)(xian)(xian)(xian)、BVVB線(xian)(xian)(xian)(xian)(xian)(xian)和(he)(he)RVV線(xian)(xian)(xian)(xian)(xian)(xian)。其(qi)中需要穿管的(de)(de)，一(yi)般只有暗裝(zhuang)的(de)(de)BV線(xian)(xian)(xian)(xian)(xian)(xian)和(he)(he)BVR線(xian)(xian)(xian)(xian)(xian)(xian)，也就(jiu)(jiu)是我們常說的(de)(de)硬線(xian)(xian)(xian)(xian)(xian)(xian)和(he)(he)軟線(xian)(xian)(xian)(xian)(xian)(xian)——沒錯BV線(xian)(xian)(xian)(xian)(xian)(xian)和(he)(he)BVR線(xian)(xian)(xian)(xian)(xian)(xian)還可以(yi)明裝(zhuang)使(shi)用(yong)，除了這兩種線(xian)(xian)(xian)(xian)(xian)(xian)，在辦公(gong)室中一(yi)般的(de)(de)弱(ruo)電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)也需要穿管的(de)(de)，不過現在金環宇電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)電(dian)(dian)纜(lan)就(jiu)(jiu)先說說日常中更為常見的(de)(de)強電(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)吧(ba)。

　　明裝(zhuang)使用時，這兩(liang)種線(xian)(xian)不需(xu)要(yao)(yao)穿管，但是需(xu)要(yao)(yao)使用明裝(zhuang)線(xian)(xian)槽——沒錯是明裝(zhuang)線(xian)(xian)槽，不是線(xian)(xian)卡。金環(huan)宇電線(xian)(xian)電纜小編認為明裝(zhuang)還是影響美觀，但對(dui)于(yu)維修或更換還是十分方便，要(yao)(yao)怎么裝(zhuang)還是個人決(jue)定吧。

　　BVVB線(xian)(xian)和(he)RVV線(xian)(xian)是明裝電(dian)(dian)線(xian)(xian)，BVVB全(quan)稱(cheng)叫銅芯聚(ju)氯(lv)乙(yi)烯絕緣(yuan)聚(ju)氯(lv)乙(yi)烯護(hu)(hu)(hu)(hu)套(tao)(tao)扁形電(dian)(dian)纜(lan)(lan)(lan)，是護(hu)(hu)(hu)(hu)套(tao)(tao)電(dian)(dian)纜(lan)(lan)(lan)中常用(yong)(yong)的(de)(de)一(yi)種型號(hao)。以金(jin)環宇電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)護(hu)(hu)(hu)(hu)套(tao)(tao)電(dian)(dian)纜(lan)(lan)(lan)為(wei)例，護(hu)(hu)(hu)(hu)套(tao)(tao)電(dian)(dian)纜(lan)(lan)(lan)是有護(hu)(hu)(hu)(hu)套(tao)(tao)層的(de)(de)單芯或(huo)多芯電(dian)(dian)線(xian)(xian)：根據性能的(de)(de)不(bu)同，該產品(pin)可分(fen)(fen)為(wei)絕緣(yuan)、阻燃(ran)、耐(nai)火三(san)種分(fen)(fen)類，不(bu)同的(de)(de)分(fen)(fen)類用(yong)(yong)途不(bu)一(yi)樣，不(bu)能埋在墻內、地下(xia)，且安裝時(shi)不(bu)需要使(shi)用(yong)(yong)線(xian)(xian)槽(cao)(cao)，只用(yong)(yong)線(xian)(xian)卡槽(cao)(cao)進行固(gu)定即(ji)可。作為(wei)明裝電(dian)(dian)線(xian)(xian)既安全(quan)實用(yong)(yong)又不(bu)影(ying)響美觀。

　　BVVB電線的絕緣材質和護套材質都是聚氯乙烯，因此，需要穿管的只有明裝BV線和明裝BVR線，其它電線和其它敷設方法，均不需要穿管。

　　對穿(chuan)管的(de)規定，嚴(yan)格來說只有兩點：

　　1、管(guan)內(nei)電(dian)線(xian)(xian)(xian)數(shu)量問題——管(guan)內(nei)電(dian)線(xian)(xian)(xian)的(de)截(jie)(jie)面積(含絕緣層(ceng))所(suo)占(zhan)電(dian)管(guan)內(nei)部(bu)空(kong)間截(jie)(jie)面積的(de)比例，不得超過40%。剩下的(de)60%，要供電(dian)線(xian)(xian)(xian)在(zai)工作時散(san)熱用(yong)。如(ru)果用(yong)16線(xian)(xian)(xian)管(guan)來算的(de)話，能(neng)夠穿(chuan)入2.5平方(fang)的(de)電(dian)線(xian)(xian)(xian)6根或(huo)4平方(fang)的(de)電(dian)線(xian)(xian)(xian)3根。

　　當然(ran)，現在許(xu)多(duo)人(ren)在施工時(shi)一(yi)般不(bu)(bu)計算了，無論(lun)2.5平(ping)(ping)方(fang)還是4平(ping)(ping)方(fang)，無論(lun)線管(guan)(guan)多(duo)粗(但肯定(ding)要比(bi)16管(guan)(guan)粗，16管(guan)(guan)只(zhi)是家用(yong)低(di)標準的(de)穿(chuan)線管(guan)(guan))，一(yi)律只(zhi)穿(chuan)入3根——裝(zhuang)修公司做的(de)類似的(de)事情不(bu)(bu)少(shao)呢，比(bi)如沒必要使用(yong)4平(ping)(ping)方(fang)電線的(de)空(kong)調掛機也一(yi)律用(yong)上(shang)4平(ping)(ping)方(fang)電線。不(bu)(bu)過(guo)用(yong)就(jiu)用(yong)吧，反正對安全(quan)性方(fang)面(mian)有益(yi)無害。（以上(shang)數據僅(jin)供參(can)考）

    2、回路(lu)穿(chuan)管問(wen)題——有的(de)(de)(de)人想法比較(jiao)另類，聽(ting)說電(dian)線(xian)數(shu)量不能超過3根(gen)(gen)，那就干脆(cui)每(mei)根(gen)(gen)電(dian)線(xian)都穿(chuan)一(yi)個(ge)管!然(ran)而這樣也不行。同一(yi)個(ge)回路(lu)內的(de)(de)(de)電(dian)線(xian)，必須穿(chuan)入同一(yi)根(gen)(gen)穿(chuan)線(xian)管內——比如(ru)一(yi)個(ge)插(cha)座(zuo)有零火地三根(gen)(gen)線(xian)，這三根(gen)(gen)線(xian)就必須在同一(yi)根(gen)(gen)管內。如(ru)果(guo)電(dian)線(xian)的(de)(de)(de)線(xian)方增加了，只能考慮增加穿(chuan)線(xian)管的(de)(de)(de)管徑，而不是(shi)把電(dian)線(xian)分開穿(chuan)管。
