電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)材質(zhi)選擇，電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)的(de)材質(zhi)是電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)工(gong)程(cheng)(cheng)設計常見的(de)另(ling)外一個問題。按照材料劃分，電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)主要(yao)有鋼(gang)(gang)(gang)制、玻璃鋼(gang)(gang)(gang)和鋁(lv)(lv)(lv)合(he)(he)金(jin)幾種。玻璃鋼(gang)(gang)(gang)電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)的(de)特(te)點是質(zhi)量輕，比(bi)(bi)(bi)重只為碳鋼(gang)(gang)(gang)的(de)1/4;耐水(shui)性和耐腐蝕性好，適(shi)合(he)(he)化(hua)工(gong)廠。不易燃(ran)燒，難燃(ran)型玻璃鋼(gang)(gang)(gang)電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)的(de)氧(yang)指數≥32。使用壽(shou)(shou)命(ming)長，一般設計壽(shou)(shou)命(ming)為20年(nian)，但價格是鋼(gang)(gang)(gang)制電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)的(de)3倍。施工(gong)的(de)優越性在于切割方便、組裝靈活，安(an)裝無需(xu)動火，這對于爆裂危險環境(jing)并(bing)且工(gong)程(cheng)(cheng)工(gong)期(qi)緊張的(de)化(hua)工(gong)廠工(gong)程(cheng)(cheng)意義尤其重大，因為在爆裂危險環境(jing)，工(gong)程(cheng)(cheng)動火安(an)裝時化(hua)工(gong)廠必須停產(chan)，經濟效(xiao)益必受影(ying)響。鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)重量也很輕，由于鋁(lv)(lv)(lv)、鋼(gang)(gang)(gang)比(bi)(bi)(bi)重不同(Al=2.7，Fe=7.86)，按重量計算，鋁(lv)(lv)(lv)鋼(gang)(gang)(gang)之比(bi)(bi)(bi)約為1:3。鋁(lv)(lv)(lv)合(he)(he)金(jin)電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)外形尺(chi)寸、荷載特(te)性均與鋼(gang)(gang)(gang)質(zhi)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)基(ji)本相近。就費用而言，鋁(lv)(lv)(lv)合(he)(he)金(jin)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)的(de)造(zao)價比(bi)(bi)(bi)鍍鋅鋼(gang)(gang)(gang)制電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)要(yao)高20%，使用壽(shou)(shou)命(ming)是鋼(gang)(gang)(gang)制電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)的(de)5倍以上。電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)可以提(ti)供電(dian)纜(lan)(lan)(lan)的(de)安(an)全通道和路徑。江蘇封閉(bi)式電(dian)纜(lan)(lan)(lan)橋(qiao)(qiao)(qiao)(qiao)架(jia)(jia)(jia)(jia)工(gong)作原理
