style="text-indent:25px">電纜橋架結(jié)構(gòu)形式及選用原則：托盤式電纜橋架（簡(jiǎn)稱：托盤）。托盤式電纜橋架在工業(yè)與民用建筑中應(yīng)用較普遍的一種。它具有重量輕、載荷大、造型美觀、結(jié)構(gòu)簡(jiǎn)單、安裝方便等優(yōu)點(diǎn)。既適用于較小直徑的強(qiáng)電電纜的安裝，也適合于弱電電纜的敷設(shè)。工程中托盤有帶蓋和不帶蓋兩種敷設(shè)方式，無(wú)蓋托盤散熱性能好，但落灰塵清掃麻煩，通常用于無(wú)塵或少塵場(chǎng)所，否則應(yīng)采用帶蓋托盤。托盤選用原則如下：（1）普通電力電纜、通信電纜布線可采用托盤布線，但無(wú)蓋托盤不允許在悶頂或吊頂內(nèi)敷設(shè)；（2）750℃、1.5h的耐火電纜可采用有蓋托盤布線，但外殼要采取防火措施。天津熱鍍鋅電纜橋架參考價(jià)電纜橋架可以根據(jù)需要進(jìn)行不同形式的安裝，包括吊裝、壁掛、地面安裝等。</p><p

style="text-indent:25px">一般情況下，控制電纜在橋架內(nèi)既可以水平排列，也可以堆放。以其橋架內(nèi)控制電纜總截面s不超過(guò)電纜橋架總截面s。的40%為原則?？刂齐娎|的總截面s為:其中:s1、s2、s3……為橋架內(nèi)各種控制電纜的截面積(包括護(hù)層部分)單位為mm，d3……為橋架內(nèi)各種控制電纜的外徑，單位為mm;nnn……為上述同種型號(hào)規(guī)格電纜的根數(shù)。相應(yīng)的控制電纜橋架的寬度為b:式中h為電纜橋架的高度，單位為mm。當(dāng)電纜橋架在室內(nèi)安裝時(shí)，為保證橋架平直美觀，整齊一致，它的水平方向載荷形變一般應(yīng)控制在4.0mm以內(nèi)。根據(jù)所選取的電纜橋架寬度和所要求的橋架水平方向載荷形變的大小，查對(duì)相應(yīng)結(jié)構(gòu)形式的橋架載荷特性曲線，當(dāng)不能滿足形變要求時(shí)，可以適當(dāng)增大橋架側(cè)高或者減小支撐間距，以便滿足要求。</p><p style="text-indent:25px">橋架的分類：如果按照橋架生產(chǎn)原材料分，大致有：鋼制橋架、鋁合金橋架、PVC材質(zhì)橋架、玻璃鋼橋架等。如果按照樣式或者應(yīng)用場(chǎng)景的不同，電纜橋架又可以分為：槽式橋架、梯式橋架、托盤式橋架、網(wǎng)格橋架、走線架、線槽、光纖槽、玻璃鋼橋架等等。如果按照加工工藝，電纜橋架又可以有：熱浸鍍鋅橋架、電鍍鋅橋架、防火噴塑橋架等等。橋架的主要作用及功能，橋架的主要功能有三方面：支撐線纜、保護(hù)線纜、管理線纜。在大眾印象中，橋架較主要的功能就是支撐線纜，以防止電纜下垂導(dǎo)致?lián)p壞。但是除此以外，用橋架敷設(shè)的線纜，在后期維修線路以及增加線纜方面，都可以很方便，快速地完成。這是傳統(tǒng)埋管方式無(wú)法相比的。電纜橋架可以應(yīng)用于室內(nèi)和室外的電纜布線。</p><p
