(4)在平行圖上繪出橋架的路由,要注明橋架起點(diǎn)、終點(diǎn)、拐彎點(diǎn)、分支點(diǎn)及升降點(diǎn)的坐標(biāo)或定位尺寸、標(biāo)高,如能繪制橋架敷設(shè)軸側(cè)圖,則對(duì)材料統(tǒng)計(jì)將更精確。 </p> <p> <br /> </p> <p> <br /> </p> <p> 直線段：注明全長、橋架層數(shù)、標(biāo)高、型號(hào)及規(guī)格。拐彎點(diǎn)和分支點(diǎn):注明所用轉(zhuǎn)彎接板的型號(hào)及規(guī)格，龍巖批發(fā)電纜橋架哪里好，龍巖批發(fā)電纜橋架哪里好，龍巖批發(fā)電纜橋架哪里好。升降段：注明標(biāo)高變化,也可用局部大樣圖或剖面圖表示。托臂、支架也要選用同樣材料，提高橋架及附件的使用壽命，電纜橋架。龍巖批發(fā)電纜橋架哪里好</p><div

3若金屬電纜橋架內(nèi)敷設(shè)的電纜為四芯電纜，且未設(shè)置**接地銅排或扁鋼，則系統(tǒng)應(yīng)設(shè)置PE干線，PE干線的截面應(yīng)按熱穩(wěn)定性要求進(jìn)行選擇，即按表4一1進(jìn)行選擇，并應(yīng)滿足機(jī)械強(qiáng)度的要求，金屬電纜橋架與PE干線間用等電位聯(lián)結(jié)線相連。所選截面對(duì)應(yīng)的電阻值必須不大于表中相應(yīng)材質(zhì)截面對(duì)應(yīng)的電阻值。 </p> <p> 若金屬電纜橋架內(nèi)敷設(shè)的電纜為五芯電纜或各回路配有PE線，且未設(shè)置**接地銅排或扁鋼，其接地保護(hù)線可參照表4一1進(jìn)行選擇，但應(yīng)同時(shí)滿足總等電位連結(jié)線的截面要求，即不超過25 m擴(kuò)，以節(jié)約有色金屬。若相線小于4mmZ，則按4. 1機(jī)械強(qiáng)度的要求進(jìn)行選擇，也就是說當(dāng)相線為1. 5m擴(kuò),PE線的截面也要選擇2. SmmZ(有機(jī)械保護(hù))或4mmZ(無機(jī)械保護(hù))。龍巖批發(fā)電纜橋架哪里好橋架水平敷設(shè)時(shí)距地面的高度一般不低于于2.5m，垂直敷設(shè)時(shí)距地面1.8m以下部分應(yīng)加金屬蓋板保護(hù)；</p><div style="width:100%;text-align: center;"><img

靜電噴涂。噴涂材料一般為聚氯乙烯粉末，聚脂粉末或防腐粉末。涂層厚度在100左右。靜電噴涂具有外表美觀、防化學(xué)腐蝕性能好的特點(diǎn)。但與金屬鍍層相比較附著強(qiáng)度低，耐沖刷和顆粒磨損能力差。使用過程中有變質(zhì)問題，易造成局部涂層脫落，從而使鋼鐵基體銹蝕，導(dǎo)致涂層大面積鼓泡剝落。另外涂層的抗紫外線能力差，一般不適合于室外使用，現(xiàn)代橋架廠生產(chǎn)的如：“靜電噴涂電纜橋架”。 </p> <p> 4．涂防銹漆。對(duì)于結(jié)構(gòu)尺寸較大的構(gòu)件，由于受鋅鍋、鍍槽、烘箱等的限制，一般只能采用涂防銹漆的方法來處理。它雖然具有成本低、使用方便等特點(diǎn)；但防腐蝕能力較差。使用壽命短，維護(hù)工作量大，一般不宜采用。（產(chǎn)品如“防銹漆電纜橋架”） </p> <p> <br /> </p><p> <p> 電纜橋架在我國的應(yīng)用只有十多年,在歐美發(fā)達(dá)國家也不過是幾十年。在一個(gè)機(jī)房項(xiàng)目中，比起造價(jià)昂貴、高科技的硬件和軟件，橋架顯的很不起眼，也很少為人關(guān)注，但它卻也是整個(gè)布線工程中不可缺少的部分。那么在施工中電纜橋架安裝施工要求及規(guī)范怎么樣？ </p> <p> <br /> </p> <p> <br /> </p> 設(shè)計(jì)要求 </p> <p> <br /> </p> <p> <br /> </p> <p> 1、橋架系統(tǒng)的路徑平面布置圖； </p> <p> <br /> </p> <p> <br /> </p> <p> 2、橋架系統(tǒng)的有關(guān)斷面圖。 </p> <p> <br /> </p> <p> <br /> </p> <p> 3、橋架系統(tǒng)所用防腐材質(zhì)及所需直通、彎通、支（吊）架等的規(guī)格和數(shù)量明細(xì)表以及必要的說明，連接板及螺絲、防護(hù)帽按以上要求由生產(chǎn)廠家配齊。4、有特殊要求的非標(biāo)準(zhǔn)技術(shù)說明或示圖。 </p> <p> <br /> </p> <p> <br /> 根據(jù)現(xiàn)場還環(huán)境及技術(shù)要求選用托盤式、槽式、梯級(jí)式、玻璃防腐阻燃電纜橋架或鋼質(zhì)普通型橋架。</p> <span style="display:none;"></span><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

按機(jī)械強(qiáng)度的要求:IEC標(biāo)準(zhǔn)對(duì)電纜橋架接地保護(hù)線的選擇規(guī)定了應(yīng)有足夠的機(jī)械強(qiáng)度，當(dāng)PE線是不與相線在同一電纜中的芯線或是不與相線在同一外保護(hù)物(例如鋼管、線槽、橋架等)內(nèi)的絕緣線時(shí)，其截面必須不小于:有機(jī)械保護(hù)的為2. 5

若電纜橋架垂直敷設(shè)在電氣豎井內(nèi)，豎井內(nèi)設(shè)有一條垂直的銅排(或鍍鋅扁鋼)作為PE干線，此時(shí)各段電纜橋架*需作等電位聯(lián)結(jié)，因?yàn)榇藭r(shí)用于電氣安全的聯(lián)結(jié)線只傳導(dǎo)電位，不傳送電流或只傳導(dǎo)少部分的電流，所以電纜橋架接地保護(hù)線截面可按4. 1要求進(jìn)行選擇電纜橋架水平敷設(shè)在設(shè)備夾層或上人馬道且低于2．5m，應(yīng)采取保護(hù)接地措施。福建批發(fā)電纜橋架供貨廠</p><p style="text-indent:25px">在公共通道或室外跨越道路段．底層橋架上宜加墊板或使用無孔托盤。龍巖批發(fā)電纜橋架哪里好</p><p> 電氣工程中經(jīng)常會(huì)碰到“防火槽盒”或“耐火槽盒”，尤其是涉及到與消防工程有關(guān)的線路。其實(shí)，“防火槽盒”只是一種通常的叫法，在相關(guān)標(biāo)準(zhǔn)中并沒有專門的術(shù)語。但從消防角度理解，它應(yīng)是具有一定耐火性能的槽盒，在火災(zāi)情況下，應(yīng)能維持一定的時(shí)間，而不致使其內(nèi)部的線路受到損壞。 </p> <p> <br /> </p> <p> <br /> </p> <p> 在實(shí)際工程中，電氣設(shè)計(jì)對(duì)槽盒的耐火性能所提的要求差別也很大。有的設(shè)計(jì)圖紙只要求槽盒外殼刷防火涂料，對(duì)于防火涂料的性能及涂刷的厚度都不提要求；有的設(shè)計(jì)圖紙要求得比較規(guī)范，明確提出了火災(zāi)情況下的維持工作時(shí)間。龍巖批發(fā)電纜橋架哪里好</p><p
