弱電(dian)(dian)(dian)(dian)機(ji)房也叫弱電(dian)(dian)(dian)(dian)間(jian)。所謂弱電(dian)(dian)(dian)(dian)是(shi)針對(dui)(dui)電(dian)(dian)(dian)(dian)力、照明用(yong)電(dian)(dian)(dian)(dian)相對(dui)(dui)而言的(de)(de)(de)。通常情況下，把電(dian)(dian)(dian)(dian)力、照明用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)能(neng)(neng)稱為強(qiang)電(dian)(dian)(dian)(dian);而把傳(chuan)播信(xin)號、進行(xing)信(xin)息交換的(de)(de)(de)電(dian)(dian)(dian)(dian)能(neng)(neng)稱為弱電(dian)(dian)(dian)(dian)。強(qiang)電(dian)(dian)(dian)(dian)的(de)(de)(de)處理(li)對(dui)(dui)象(xiang)是(shi)能(neng)(neng)源(電(dian)(dian)(dian)(dian)力)，其特點(dian)是(shi)電(dian)(dian)(dian)(dian)壓(ya)高、電(dian)(dian)(dian)(dian)流大、功耗大、頻率(lv)低，主(zhu)要考慮(lv)的(de)(de)(de)問(wen)題是(shi)減(jian)小損耗、提(ti)高效(xiao)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(shi)(shi)用來敷設(she)弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)線(xian)(xian)路(纜(lan))的(de)(de)一個(應該說是(shi)(shi))通道.弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)井(jing)在指定的(de)(de)樓(lou)層(ceng)會設(she)制檢查(cha)口,方(fang)便給專(zhuan)業工作人員檢查(cha)弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)線(xian)(xian)路(纜(lan))用的(de)(de). 弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)線(xian)(xian)路(纜(lan))在弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)井(jing)里(li)敷設(she)即(ji)可以保護(hu)弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)線(xian)(xian)路(纜(lan))減少人為的(de)(de)破壞(huai),又可方(fang)便專(zhuan)業施工人員定時檢查(cha)維護(hu),而(er)且線(xian)(xian)路(纜(lan))從(cong)弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)井(jing)走,不會影響大樓(lou)的(de)(de)整體影響,比較美觀. 弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian)也不僅(jin)僅(jin)是(shi)(shi)指通訊(xun),其實有線(xian)(xian)電(dian)(dian)視線(xian)(xian)(纜(lan))、消(xiao)防報警線(xian)(xian)(纜(lan))等(deng)等(deng)都屬于(yu)弱(ruo)(ruo)(ruo)(ruo)(ruo)(ruo)電(dian)(dian).
