弱電(dian)(dian)(dian)(dian)機房也叫弱電(dian)(dian)(dian)(dian)間(jian)。所謂弱電(dian)(dian)(dian)(dian)是針對電(dian)(dian)(dian)(dian)力(li)、照明用電(dian)(dian)(dian)(dian)相對而言的(de)。通常情況下，把(ba)電(dian)(dian)(dian)(dian)力(li)、照明用的(de)電(dian)(dian)(dian)(dian)能(neng)稱為(wei)強(qiang)電(dian)(dian)(dian)(dian);而把(ba)傳播信號、進行(xing)信息交換的(de)電(dian)(dian)(dian)(dian)能(neng)稱為(wei)弱電(dian)(dian)(dian)(dian)。強(qiang)電(dian)(dian)(dian)(dian)的(de)處理對象是能(neng)源(電(dian)(dian)(dian)(dian)力(li))，其特(te)點(dian)是電(dian)(dian)(dian)(dian)壓高、電(dian)(dian)(dian)(dian)流(liu)大(da)、功耗大(da)、頻率(lv)低，主要考慮的(de)問(wen)題是減小(xiao)損耗、提高效率(lv)。

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(yong)來(lai)敷(fu)設(she)弱(ruo)(ruo)電線(xian)(xian)(xian)路(lu)(纜(lan)(lan)(lan))的(de)(de)一個(ge)(應該說是)通道.弱(ruo)(ruo)電井在指(zhi)定的(de)(de)樓層會設(she)制檢(jian)查(cha)口(kou),方便給專(zhuan)業工(gong)作(zuo)人(ren)員檢(jian)查(cha)弱(ruo)(ruo)電線(xian)(xian)(xian)路(lu)(纜(lan)(lan)(lan))用(yong)的(de)(de). 弱(ruo)(ruo)電線(xian)(xian)(xian)路(lu)(纜(lan)(lan)(lan))在弱(ruo)(ruo)電井里敷(fu)設(she)即可(ke)以保護(hu)弱(ruo)(ruo)電線(xian)(xian)(xian)路(lu)(纜(lan)(lan)(lan))減少人(ren)為的(de)(de)破壞,又可(ke)方便專(zhuan)業施工(gong)人(ren)員定時檢(jian)查(cha)維護(hu),而且線(xian)(xian)(xian)路(lu)(纜(lan)(lan)(lan))從弱(ruo)(ruo)電井走,不(bu)會影(ying)響大樓的(de)(de)整體(ti)影(ying)響,比較美觀. 弱(ruo)(ruo)電也(ye)不(bu)僅僅是指(zhi)通訊,其實(shi)有線(xian)(xian)(xian)電視線(xian)(xian)(xian)(纜(lan)(lan)(lan))、消防報(bao)警線(xian)(xian)(xian)(纜(lan)(lan)(lan))等等都屬于弱(ruo)(ruo)電.
