弱電(dian)(dian)(dian)(dian)(dian)機房(fang)也(ye)叫(jiao)弱電(dian)(dian)(dian)(dian)(dian)間。所謂弱電(dian)(dian)(dian)(dian)(dian)是針(zhen)對(dui)電(dian)(dian)(dian)(dian)(dian)力(li)(li)、照(zhao)明用電(dian)(dian)(dian)(dian)(dian)相對(dui)而言(yan)的(de)。通常情況下，把電(dian)(dian)(dian)(dian)(dian)力(li)(li)、照(zhao)明用的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)稱為(wei)強(qiang)電(dian)(dian)(dian)(dian)(dian);而把傳(chuan)播信號、進行信息交換(huan)的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)稱為(wei)弱電(dian)(dian)(dian)(dian)(dian)。強(qiang)電(dian)(dian)(dian)(dian)(dian)的(de)處理對(dui)象(xiang)是能(neng)源(yuan)(電(dian)(dian)(dian)(dian)(dian)力(li)(li))，其特點(dian)是電(dian)(dian)(dian)(dian)(dian)壓高、電(dian)(dian)(dian)(dian)(dian)流大(da)、功耗大(da)、頻率(lv)低，主要考慮(lv)的(de)問題是減小損(sun)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(jing)是用(yong)來(lai)敷設弱(ruo)(ruo)電(dian)線(xian)(xian)路(纜(lan)(lan)(lan))的一個(應該說(shuo)是)通道(dao).弱(ruo)(ruo)電(dian)井(jing)在指定的樓層會設制檢查口,方便給專業工(gong)(gong)作(zuo)人員檢查弱(ruo)(ruo)電(dian)線(xian)(xian)路(纜(lan)(lan)(lan))用(yong)的. 弱(ruo)(ruo)電(dian)線(xian)(xian)路(纜(lan)(lan)(lan))在弱(ruo)(ruo)電(dian)井(jing)里敷設即可以(yi)保護弱(ruo)(ruo)電(dian)線(xian)(xian)路(纜(lan)(lan)(lan))減少人為(wei)的破壞,又可方便專業施工(gong)(gong)人員定時檢查維護,而(er)且(qie)線(xian)(xian)路(纜(lan)(lan)(lan))從弱(ruo)(ruo)電(dian)井(jing)走,不會影響大樓的整體影響,比較(jiao)美觀. 弱(ruo)(ruo)電(dian)也(ye)不僅(jin)僅(jin)是指通訊,其(qi)實有線(xian)(xian)電(dian)視線(xian)(xian)(纜(lan)(lan)(lan))、消防報(bao)警線(xian)(xian)(纜(lan)(lan)(lan))等等都屬于弱(ruo)(ruo)電(dian).
