常用阻燃電線電纜非金屬材料容量計算及參考表

1、附錄B常用阻燃電線電纜非金屬材料容量計算及參考表阻燃電纜設計時宜按照垂直安裝的成束電線或電纜的火焰垂直蔓延試驗（GB/T18380.31-200818380.36-2008 ）的計算方法確定同一環(huán)境中敷設的每米成束電纜所含非金屬材料的總體積，以求得阻燃類別。單根電線電纜每米所含非金屬材料的容量，可按下列近似公式計算：V=（S i-S2）/1000式中V 電線電纜所含非金屬材料容量之和，L/m ;51 不同阻燃級別規(guī)定每米電線電纜所含非金屬材料容量，L/m ;52 電線電纜金屬截面積之和，m不同阻燃級別相應的電纜電線根數；N = Vs/V式中N 不同阻燃級別相應的電纜電線根數；Vs 不同阻燃級別

2、規(guī)定每米電線電纜所含非金屬材料容量，L/m ;V 每米電線電纜所含非金屬材料容量之和，L/m。常用額定電壓0.6/1 kV 阻燃電線電纜每米非金屬材料容量及不同阻燃類別/電線電纜根數，參見表 。表電力電纜非金屬容量和不同阻燃類別/根數參考表1C （單芯）2C （2等芯）截面mr2外徑mm非金屬含量L/mA類 （根）B類 （根）C類 （根）截面mr2外徑mm非金屬含量L/mA類 （根）B類 （根）46.40.028224812453411.60.097772361567.00.032521510846612.70.1147613113108.20.042816482351015.20.16154
