弱電(dian)(dian)機房也叫(jiao)弱電(dian)(dian)間。所謂弱電(dian)(dian)是(shi)針(zhen)對(dui)電(dian)(dian)力(li)、照(zhao)(zhao)明用(yong)電(dian)(dian)相對(dui)而言的(de)。通常(chang)情況下，把(ba)電(dian)(dian)力(li)、照(zhao)(zhao)明用(yong)的(de)電(dian)(dian)能(neng)稱為(wei)(wei)強電(dian)(dian);而把(ba)傳(chuan)播信(xin)號、進行信(xin)息交換(huan)的(de)電(dian)(dian)能(neng)稱為(wei)(wei)弱電(dian)(dian)。強電(dian)(dian)的(de)處(chu)理對(dui)象是(shi)能(neng)源(電(dian)(dian)力(li))，其特點是(shi)電(dian)(dian)壓高、電(dian)(dian)流(liu)大(da)、功耗大(da)、頻率低，主(zhu)要(yao)考(kao)慮的(de)問題(ti)是(shi)減小損耗、提高效率。

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(shi)用(yong)來敷設弱(ruo)(ruo)電(dian)(dian)(dian)線(xian)(xian)路(纜(lan)(lan)(lan))的(de)(de)一個(ge)(應該說是(shi))通道.弱(ruo)(ruo)電(dian)(dian)(dian)井在(zai)指定的(de)(de)樓(lou)層會設制檢(jian)查口,方(fang)便給專業(ye)工作人員檢(jian)查弱(ruo)(ruo)電(dian)(dian)(dian)線(xian)(xian)路(纜(lan)(lan)(lan))用(yong)的(de)(de). 弱(ruo)(ruo)電(dian)(dian)(dian)線(xian)(xian)路(纜(lan)(lan)(lan))在(zai)弱(ruo)(ruo)電(dian)(dian)(dian)井里敷設即可以保護弱(ruo)(ruo)電(dian)(dian)(dian)線(xian)(xian)路(纜(lan)(lan)(lan))減少人為(wei)的(de)(de)破壞,又可方(fang)便專業(ye)施工人員定時檢(jian)查維護,而且(qie)線(xian)(xian)路(纜(lan)(lan)(lan))從弱(ruo)(ruo)電(dian)(dian)(dian)井走,不(bu)會影(ying)響(xiang)(xiang)大樓(lou)的(de)(de)整體影(ying)響(xiang)(xiang),比(bi)較(jiao)美觀. 弱(ruo)(ruo)電(dian)(dian)(dian)也不(bu)僅(jin)僅(jin)是(shi)指通訊,其實(shi)有線(xian)(xian)電(dian)(dian)(dian)視線(xian)(xian)(纜(lan)(lan)(lan))、消防(fang)報(bao)警線(xian)(xian)(纜(lan)(lan)(lan))等(deng)等(deng)都(dou)屬(shu)于弱(ruo)(ruo)電(dian)(dian)(dian).
