橋(qiao)(qiao)架(jia)是(shi)由托(tuo)盤、梯(ti)架(jia)的(de)直(zhi)(zhi)線(xian)(xian)段(duan)、彎(wan)通(tong)(tong)(tong)、附件以及支、吊(diao)架(jia)等(deng)構(gou)成，用(yong)(yong)以支承電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)具有連續的(de)剛(gang)性結構(gou)系統(tong)的(de)總稱。是(shi)應用(yong)(yong)在水(shui)平(ping)布(bu)線(xian)(xian)和垂直(zhi)(zhi)布(bu)線(xian)(xian)系統(tong)的(de)安裝通(tong)(tong)(tong)道。電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)橋(qiao)(qiao)架(jia)是(shi)使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)、電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)、管纜(lan)(lan)鋪設達到標準化、系列化、通(tong)(tong)(tong)用(yong)(yong)化的(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)鋪設裝置(zhi)。這里需要提到一(yi)(yi)個托(tuo)盤的(de)概念，很多人(ren)把(ba)橋(qiao)(qiao)架(jia)與托(tuo)盤混為一(yi)(yi)體，認為功能大(da)(da)(da)體相(xiang)同，其實不然。橋(qiao)(qiao)架(jia)與線(xian)(xian)槽(cao)存(cun)在很大(da)(da)(da)的(de)區(qu)別(bie)，主要有：橋(qiao)(qiao)架(jia)主要用(yong)(yong)于敷(fu)設電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)和控制電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)，線(xian)(xian)槽(cao)用(yong)(yong)于敷(fu)設導線(xian)(xian)和通(tong)(tong)(tong)訊線(xian)(xian)纜(lan)(lan)；橋(qiao)(qiao)架(jia)相(xiang)對(dui)大(da)(da)(da)（200×100到600×200)，線(xian)(xian)槽(cao)相(xiang)對(dui)較(jiao)小(xiao)；橋(qiao)(qiao)架(jia)拐彎(wan)半徑比(bi)較(jiao)大(da)(da)(da)，線(xian)(xian)槽(cao)大(da)(da)(da)部分拐直(zhi)(zhi)角彎(wan)；橋(qiao)(qiao)架(jia)跨距比(bi)較(jiao)大(da)(da)(da)，線(xian)(xian)槽(cao)比(bi)較(jiao)小(xiao)；固(gu)定、安裝方式不同；在某些場所，橋(qiao)(qiao)架(jia)沒蓋(gai)，線(xian)(xian)槽(cao)通(tong)(tong)(tong)常全(quan)是(shi)帶蓋(gai)封閉的(de)線(xian)(xian)槽(cao)來走線(xian)(xian)，橋(qiao)(qiao)架(jia)則是(shi)用(yong)(yong)來走電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)。因此，大(da)(da)(da)家在選用(yong)(yong)橋(qiao)(qiao)架(jia)時(shi)應注意，以免選錯而沒有達到自己預期的(de)目的(de)。
