style="text-indent:25px">橋架的選擇我們其實是有著很多的要求的，其中防火要求可以說是比較重要的一點了，對于這點，我們一般是有著這些要求的：為了能夠確保橋架的防火性能，我們除了需要它具有基本的防火要求之外，還需要它采用更加安全的材質(zhì)制作，而且防火金屬電纜橋架是比較合適的。其次就是對橋架的各項資料以及證書進行檢查了，要嚴格檢查產(chǎn)品的質(zhì)量合格證書。還有很重要的一點就是施工人員的施工了，我們在施工的時候如果施工不當?shù)脑挘敲匆彩菚蚣艿姆阑鹦阅苡兄^大的影響的，因此我們需要注意到這幾個方面，那么我們就可以選擇到具有不錯防火性能的橋架了。鋁合金槽式電纜橋架敷設走向應短捷，并應盡量沿墻、沿柱或沿梁敷設。靜安區(qū)鋁合金鍍鋅橋架生產(chǎn)銷售</p><p

style="text-indent:25px">橋架被稱為“電纜”的好幫手，實實在在的保護著電纜，可以防止電纜受到嚴重的干擾和腐蝕。同時要注意：不得戶外安裝（畢竟是鍍鋅鐵，遇到水會生銹），不得在高腐蝕環(huán)境安裝。橋架跨接線連接方法：橫平豎直，彎頭處要平緩。當橋架分層時，建議用組合架。由于橋架的金屬支撐懸掛結(jié)構(gòu)不符合國家關于電氣設備的接地標準，所以要用跨接地線連接。鍍鋅橋架可以省略，漆面的橋架必須有跨接地線。電線橋架之間的軟連接一般是通過紫銅編織線和鍍錫銅編織線等來實現(xiàn)的；橋架的接頭的地連接是要用軟銅排連的作用：一防雷。第二對電力線的監(jiān)測。若電力線出現(xiàn)斷路上邊的信號線的電場發(fā)生變化，監(jiān)控室或監(jiān)控設備就能做出相應的動作。定制跨接線首先確定三要素，分別是長度、寬度、孔徑。然后再根據(jù)其需要選擇材質(zhì)，材質(zhì)可分為紫銅和鍍錫銅，紫銅為裸銅表面，鍍錫銅則表面鍍錫，起到耐氧化作用的。黃浦區(qū)鋁合金梯形橋架報價</p></p><br
