電纜橋架在生(sheng)活(huo)中主(zhu)要是用(yong)于電力(li)系統(tong)，保(bao)證(zheng)日常的(de)電力(li)使用(yong)，先(xian)了解(jie)下電纜(lan)橋架的(de)品種(zhong)吧(ba)！

1、需屏蔽(bi)電氣(qi)干擾的(de)電纜網(wang)路或(huo)有(you)防護外(wai)部（如：有(you)腐蝕液休，易燃粉塵等(deng)環境）影響的(de)要(yao)求時，應選用復合類槽式復合型防腐屏蔽(bi)電纜橋架（帶(dai)蓋）

2、強(qiang)腐(fu)蝕性環(huan)境(jing)應(ying)采用(yong)類復(fu)合環(huan)氧樹(shu)脂防腐(fu)阻(zu)燃型(xing)電纜(lan)橋(qiao)架。托臂、支架也(ye)要選用(yong)同樣材料，提(ti)高橋(qiao)架及(ji)附件(jian)的(de)使用(yong)壽命，電纜(lan)橋(qiao)架。在容易(yi)積(ji)灰和其它需遮蓋(gai)的(de)環(huan)境(jing)或戶外場所宜加(jia)蓋(gai)板。

3、除上述情況外，可(ke)根據現場還環境(jing)及技術(shu)要(yao)求選用托盤式(shi)、槽式(shi)、梯(ti)級式(shi)、玻(bo)璃(li)防腐(fu)阻燃電纜橋架(jia)(jia)或(huo)鋼質普通型橋架(jia)(jia)。在容易積灰和其它需遮蓋(gai)的環境(jing)或(huo)戶外場所宜加蓋(gai)板。

4、在(zai)公(gong)共(gong)通道或(huo)戶外跨越道路段，底層梯級的底部宜(yi)加墊(dian)板或(huo)在(zai)該段使(shi)用(yong)托盤。大跨距跨越公(gong)共(gong)通道時，可根據(ju)用(yong)戶要求提(ti)高橋(qiao)架(jia)的載荷(he)能力或(huo)選用(yong)行架(jia)。

5、大跨距（>3m）要選用復合型橋架。

6、戶外要選(xuan)用復合環氧(yang)樹指橋架。

橋架的(de)(de)(de)(de)安裝(zhuang)方法(fa)如下(xia)：橋架安裝(zhuang)適用(yong)于(yu)正常環境的(de)(de)(de)(de)室內(nei)(nei)干燥和不(bu)(bu)易受機(ji)械損傷的(de)(de)(de)(de)場所明(ming)敷，但對(dui)橋架有嚴重腐蝕的(de)(de)(de)(de)場所不(bu)(bu)應(ying)(ying)采(cai)(cai)用(yong)。金屬線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)應(ying)(ying)平整(zheng)、無扭曲(qu)變形，內(nei)(nei)壁(bi)應(ying)(ying)光滑(hua)、無毛刺。橋架垂(chui)直或(huo)(huo)傾斜安裝(zhuang)時(shi)，應(ying)(ying)采(cai)(cai)取措施防止電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)或(huo)(huo)電(dian)(dian)(dian)纜(lan)在(zai)線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)內(nei)(nei)移動(dong)。同(tong)一回路的(de)(de)(de)(de)所有相(xiang)線(xian)(xian)(xian)(xian)(xian)(xian)和中(zhong)性(xing)線(xian)(xian)(xian)(xian)(xian)(xian)，應(ying)(ying)敷設(she)(she)在(zai)同(tong)一金屬線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)內(nei)(nei)。同(tong)一路徑無防干擾要(yao)求的(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)路，可(ke)敷設(she)(she)于(yu)同(tong)一橋架內(nei)(nei)，線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)內(nei)(nei)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)或(huo)(huo)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)總截面(mian)（包括外護(hu)層）不(bu)(bu)應(ying)(ying)超過線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)內(nei)(nei)截面(mian)的(de)(de)(de)(de)20％，載流導(dao)線(xian)(xian)(xian)(xian)(xian)(xian)不(bu)(bu)宜超過30根(gen)。控制、信號或(huo)(huo)與其相(xiang)類似的(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)路，電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)或(huo)(huo)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)總截向下(xia)應(ying)(ying)超過線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)內(nei)(nei)截面(mian)的(de)(de)(de)(de)50％，電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)或(huo)(huo)電(dian)(dian)(dian)纜(lan)根(gen)數下(xia)限。橋架應(ying)(ying)可(ke)靠接地(di)或(huo)(huo)接零，但不(bu)(bu)應(ying)(ying)作為設(she)(she)備的(de)(de)(de)(de)接地(di)導(dao)體(ti)。由金屬線(xian)(xian)(xian)(xian)(xian)(xian)槽(cao)引出的(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)路，可(ke)采(cai)(cai)用(yong)金屬管，硬質(zhi)塑(su)(su)料管、半硬塑(su)(su)料管、金屬軟(ruan)管或(huo)(huo)電(dian)(dian)(dian)纜(lan)等布線(xian)(xian)(xian)(xian)(xian)(xian)方式。電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)(xian)或(huo)(huo)電(dian)(dian)(dian)纜(lan)在(zai)引出部(bu)分(fen)不(bu)(bu)得遭受損傷。
