山東電纜橋架安裝的三種準(zhǔn)備
1.如果與動力電纜橋架一起使用,則動力電纜和山東電纜橋架應(yīng)通過第二個電纜橋架制造商的一個部門在后面分開.

2.堿基形成
2.Baseformation
(1)負(fù)荷計(jì)算:計(jì)算電纜重量沿電纜干線的長度。
(1)Loadcalculation:calculatethelengthofcableweightalongthemaincableline.
(2)確定方向:根據(jù)建筑布局平面圖確定電纜橋架的更佳路徑,并結(jié)合管道、電氣管線、方便維護(hù)和電纜敷設(shè)位置的設(shè)置。在室內(nèi),其應(yīng)指向長墻、柱,建筑物的橫梁和地板可能。如果有可能使用綜合管道,則應(yīng)將其平行于管道,并考慮將其向下引導(dǎo)和分支,以避免可能發(fā)生交叉。如果沒有用于借用的其他管道框架,則必須自行設(shè)置(支撐)列。
(2)Determinedirection:determinethebestpathofcabletrayaccordingtothebuildinglayoutplan,andcombinewiththesettingofpipeline,electricalpipeline,convenientmaintenanceandcablelayingposition.Indoors,itshouldpointtolongwalls,columns,beamsandfloorsofbuildingswherepossible.Ifitispossibletouseanintegratedpipeline,itshouldbeparalleltothepipelineandconsiderguidingitdownandbranchingittoavoidpossibleintersections.Ifyoudonothaveanotherpipeframeforborrowing,youmustsetthe(support)columnyourself.
(3)確定橋?qū)挘捍_定電纜橋架的型號和規(guī)格、支撐臂的長度、電纜的長度、寬度和層數(shù),根據(jù)電纜的編號、電纜的直徑和電纜之間的距離。
(3)Determinethebridgewidth:determinethemodelandspecificationofthecablebridge,thelengthofthesupportarm,thelength,widthandnumberoflayersofthecable,accordingtothenumberofthecable,thediameterofthecableandthedistancebetweenthecables.
(4)繪制電纜橋架的平面圖和截面圖,并繪制空間圖和部分材料表。
(4)Drawtheplanandsectionofthecabletray,anddrawthespacedrawingandsomematerialtables.
(5)確定安裝方式:根據(jù)橋梁的固定條件確定固定方式,并選擇吊桿式、垂直式、側(cè)壁式、混合式,一般情況下,結(jié)合橋梁結(jié)構(gòu),選擇橋墩結(jié)構(gòu)。
(5)Determinetheinstallationmode:determinethefixedmodeaccordingtothefixedconditionsofthebridge,andselectthesuspendertype,verticaltype,sidewalltypeandhybridtype.Generally,selectthepierstructureincombinationwiththebridgestructure.
3.當(dāng)交流電纜和其他低壓電纜共用電橋時,具有外部屏蔽層的弱電流系統(tǒng)的弱電流電纜應(yīng)選擇更佳,以避免相互干擾。

從行業(yè)的發(fā)展趨勢來看,盡管有紡織工業(yè)、泰豐電纜橋架等行業(yè)的競爭,但通過對電纜橋架的科技創(chuàng)新和技術(shù)攻關(guān),已發(fā)展成為具有較高質(zhì)量和服務(wù)水平的國內(nèi)電纜橋架設(shè)備制造企業(yè),并已在新的電纜行業(yè)中填寫,重新監(jiān)測設(shè)備,并在生產(chǎn)線的電纜設(shè)備欄中填寫投資項(xiàng)目。
