橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)是由托盤、梯架(jia)(jia)(jia)(jia)的(de)(de)直線(xian)(xian)(xian)段、彎通(tong)、附件(jian)以(yi)及支(zhi)、吊架(jia)(jia)(jia)(jia)等構(gou)成，用(yong)(yong)以(yi)支(zhi)承電(dian)(dian)纜(lan)(lan)的(de)(de)具有(you)連(lian)續的(de)(de)剛性結構(gou)系統(tong)(tong)的(de)(de)總稱。是應(ying)用(yong)(yong)在水(shui)平布線(xian)(xian)(xian)和(he)垂直布線(xian)(xian)(xian)系統(tong)(tong)的(de)(de)安(an)裝(zhuang)通(tong)道。電(dian)(dian)纜(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)是使電(dian)(dian)線(xian)(xian)(xian)、電(dian)(dian)纜(lan)(lan)、管纜(lan)(lan)鋪(pu)設(she)(she)達到標準化(hua)(hua)(hua)、系列化(hua)(hua)(hua)、通(tong)用(yong)(yong)化(hua)(hua)(hua)的(de)(de)電(dian)(dian)纜(lan)(lan)鋪(pu)設(she)(she)裝(zhuang)置(zhi)。這(zhe)里(li)需(xu)要提到一個托盤的(de)(de)概念，很多人把橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)與托盤混為(wei)一體，認為(wei)功(gong)能大(da)體相(xiang)同，其實不(bu)然。橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)與線(xian)(xian)(xian)槽(cao)存在很大(da)的(de)(de)區別，主(zhu)要有(you)：橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)主(zhu)要用(yong)(yong)于敷設(she)(she)電(dian)(dian)力電(dian)(dian)纜(lan)(lan)和(he)控制電(dian)(dian)纜(lan)(lan)，線(xian)(xian)(xian)槽(cao)用(yong)(yong)于敷設(she)(she)導線(xian)(xian)(xian)和(he)通(tong)訊線(xian)(xian)(xian)纜(lan)(lan)；橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)相(xiang)對大(da)（200×100到600×200)，線(xian)(xian)(xian)槽(cao)相(xiang)對較小；橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)拐彎半徑比(bi)較大(da)，線(xian)(xian)(xian)槽(cao)大(da)部分(fen)拐直角彎；橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)跨(kua)距比(bi)較大(da)，線(xian)(xian)(xian)槽(cao)比(bi)較小；固定(ding)、安(an)裝(zhuang)方式不(bu)同；在某些場所，橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)沒蓋(gai)，線(xian)(xian)(xian)槽(cao)通(tong)常全是帶蓋(gai)封(feng)閉的(de)(de)線(xian)(xian)(xian)槽(cao)來走線(xian)(xian)(xian)，橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)則(ze)是用(yong)(yong)來走電(dian)(dian)纜(lan)(lan)的(de)(de)。因此，大(da)家在選用(yong)(yong)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)時應(ying)注意，以(yi)免選錯而沒有(you)達到自己預期的(de)(de)目的(de)(de)。
