弱(ruo)(ruo)(ruo)電(dian)(dian)(dian)(dian)(dian)機房也叫弱(ruo)(ruo)(ruo)電(dian)(dian)(dian)(dian)(dian)間(jian)。所謂弱(ruo)(ruo)(ruo)電(dian)(dian)(dian)(dian)(dian)是(shi)針(zhen)對(dui)電(dian)(dian)(dian)(dian)(dian)力、照(zhao)明(ming)(ming)用電(dian)(dian)(dian)(dian)(dian)相(xiang)對(dui)而(er)(er)言(yan)的(de)。通常情況(kuang)下，把電(dian)(dian)(dian)(dian)(dian)力、照(zhao)明(ming)(ming)用的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)稱(cheng)為強(qiang)電(dian)(dian)(dian)(dian)(dian);而(er)(er)把傳播(bo)信(xin)(xin)號、進(jin)行信(xin)(xin)息(xi)交換(huan)的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)稱(cheng)為弱(ruo)(ruo)(ruo)電(dian)(dian)(dian)(dian)(dian)。強(qiang)電(dian)(dian)(dian)(dian)(dian)的(de)處(chu)理對(dui)象(xiang)是(shi)能(neng)源(yuan)(電(dian)(dian)(dian)(dian)(dian)力)，其特點是(shi)電(dian)(dian)(dian)(dian)(dian)壓高、電(dian)(dian)(dian)(dian)(dian)流(liu)大、功耗(hao)大、頻率低，主要考慮(lv)的(de)問題是(shi)減(jian)小損(sun)耗(hao)、提(ti)高效率。

弱電工程包括電視工程、通信工程、消防工程、保安工程、影像工程等等和為上述工程服務的綜合布線工程。弱電是針對強電而言的。強電=(380/220)、高壓不管。 弱電井是用來敷(fu)設弱(ruo)電(dian)(dian)線路(纜(lan)(lan))的一個(應該說(shuo)是)通(tong)道(dao).弱(ruo)電(dian)(dian)井在指定的樓層會設制(zhi)檢(jian)查口,方(fang)便給(gei)專業(ye)工(gong)(gong)作人員檢(jian)查弱(ruo)電(dian)(dian)線路(纜(lan)(lan))用的. 弱(ruo)電(dian)(dian)線路(纜(lan)(lan))在弱(ruo)電(dian)(dian)井里敷(fu)設即可(ke)以保護弱(ruo)電(dian)(dian)線路(纜(lan)(lan))減少人為的破壞,又可(ke)方(fang)便專業(ye)施(shi)工(gong)(gong)人員定時(shi)檢(jian)查維護,而且(qie)線路(纜(lan)(lan))從弱(ruo)電(dian)(dian)井走,不會影響大樓的整體(ti)影響,比(bi)較美觀. 弱(ruo)電(dian)(dian)也(ye)不僅(jin)僅(jin)是指通(tong)訊,其實(shi)有線電(dian)(dian)視線(纜(lan)(lan))、消(xiao)防報(bao)警線(纜(lan)(lan))等等都屬于(yu)弱(ruo)電(dian)(dian).
