電(dian)(dian)纜(lan)(lan)橋(qiao)架(jia)(jia)的電(dian)(dian)纜(lan)(lan)敷(fu)設(she)方(fang)(fang)式具有明顯的優點(dian),不(bu)論(lun)廠區主(zhu)干(gan)線路或某個裝(zhuang)置內(nei)的配線,均可采用電(dian)(dian)纜(lan)(lan)橋(qiao)架(jia)(jia)敷(fu)設(she)方(fang)(fang)式。電(dian)(dian)纜(lan)(lan)直埋雖然土建造價(jia)較低，但(dan)其占(zhan)地面積(ji)大(da)，裝(zhuang)置擴建時增加(jia)電(dian)(dian)纜(lan)(lan)要(yao)重新(xin)開(kai)挖，常因(yin)擴建施工等損壞電(dian)(dian)纜(lan)(lan)，造成停電(dian)(dian)事故，且事故處(chu)理困難，恢(hui)復供電(dian)(dian)所(suo)需時間較長，電(dian)(dian)纜(lan)(lan)直埋時需選(xuan)用鎧裝(zhuang)電(dian)(dian)纜(lan)(lan)，其價(jia)格(ge)比(bi)一般電(dian)(dian)纜(lan)(lan)貴，彎曲(qu)不(bu)便。
電(dian)(dian)纜溝(gou)(gou)(gou)方(fang)(fang)案雖然和電(dian)(dian)纜直(zhi)(zhi)埋(mai)相比(bi)，具有一(yi)定(ding)的(de)靈(ling)活性，但(dan)石化(hua)(hua)企業(ye)大多都是(shi)易(yi)燃易(yi)爆場所，電(dian)(dian)纜溝(gou)(gou)(gou)易(yi)聚集危(wei)險氣體，造(zao)成(cheng)隱(yin)患，并且化(hua)(hua)工地(di)表水(shui)大多含有化(hua)(hua)工物料(liao)，時(shi)間長了，必然會對電(dian)(dian)纜溝(gou)(gou)(gou)造(zao)成(cheng)污染。電(dian)(dian)纜溝(gou)(gou)(gou)一(yi)般深一(yi)米(mi)左右，上有蓋板，人員巡檢多有不(bu)便。電(dian)(dian)纜隧道雖然具有維修，增加電(dian)(dian)纜方(fang)(fang)便的(de)特點，但(dan)因它(ta)處在(zai)地(di)下，電(dian)(dian)纜多散(san)熱條件(jian)差，一(yi)般需強(qiang)制通風，時(shi)時(shi)還受(shou)到(dao)滲(shen)漏的(de)困擾，需定(ding)期排(pai)水(shui)，運行費用(yong)(yong)高。電(dian)(dian)纜隧道只能在(zai)電(dian)(dian)纜集中地(di)段使用(yong)(yong)，電(dian)(dian)纜引(yin)出(chu)后，仍需采用(yong)(yong)直(zhi)(zhi)埋(mai)或(huo)電(dian)(dian)纜溝(gou)(gou)(gou)方(fang)(fang)式，不(bu)可避免地(di)又出(chu)現了該(gai)方(fang)(fang)式的(de)缺點。
