橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)是(shi)由(you)托(tuo)盤(pan)(pan)、梯架(jia)(jia)(jia)的(de)(de)(de)直(zhi)線(xian)段、彎(wan)通(tong)(tong)、附件以及支、吊架(jia)(jia)(jia)等構成，用以支承電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)具有連續的(de)(de)(de)剛(gang)性結構系統的(de)(de)(de)總稱。是(shi)應用在(zai)(zai)水平布線(xian)和垂直(zhi)布線(xian)系統的(de)(de)(de)安(an)裝通(tong)(tong)道。電(dian)(dian)(dian)(dian)纜(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)是(shi)使電(dian)(dian)(dian)(dian)線(xian)、電(dian)(dian)(dian)(dian)纜(lan)、管纜(lan)鋪設(she)(she)達到(dao)標準化、系列化、通(tong)(tong)用化的(de)(de)(de)電(dian)(dian)(dian)(dian)纜(lan)鋪設(she)(she)裝置(zhi)。這(zhe)里需要(yao)(yao)提到(dao)一個托(tuo)盤(pan)(pan)的(de)(de)(de)概念，很多人(ren)把橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)與托(tuo)盤(pan)(pan)混為(wei)一體，認為(wei)功能(neng)大(da)(da)體相(xiang)同，其實不然。橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)與線(xian)槽(cao)(cao)(cao)(cao)(cao)存在(zai)(zai)很大(da)(da)的(de)(de)(de)區別，主要(yao)(yao)有：橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)主要(yao)(yao)用于敷設(she)(she)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)和控制(zhi)電(dian)(dian)(dian)(dian)纜(lan)，線(xian)槽(cao)(cao)(cao)(cao)(cao)用于敷設(she)(she)導(dao)線(xian)和通(tong)(tong)訊線(xian)纜(lan)；橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)相(xiang)對大(da)(da)（200×100到(dao)600×200)，線(xian)槽(cao)(cao)(cao)(cao)(cao)相(xiang)對較小；橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)拐彎(wan)半徑比較大(da)(da)，線(xian)槽(cao)(cao)(cao)(cao)(cao)大(da)(da)部分拐直(zhi)角彎(wan)；橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)跨距(ju)比較大(da)(da)，線(xian)槽(cao)(cao)(cao)(cao)(cao)比較小；固(gu)定、安(an)裝方式不同；在(zai)(zai)某(mou)些場所，橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)沒(mei)蓋，線(xian)槽(cao)(cao)(cao)(cao)(cao)通(tong)(tong)常全是(shi)帶蓋封閉(bi)的(de)(de)(de)線(xian)槽(cao)(cao)(cao)(cao)(cao)來走線(xian)，橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)則是(shi)用來走電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)。因此(ci)，大(da)(da)家在(zai)(zai)選用橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)時應注意，以免(mian)選錯而(er)沒(mei)有達到(dao)自己預期的(de)(de)(de)目的(de)(de)(de)。
