摘要
随着我国经济的快速发展,电气引起的火灾逐年增多,其中因电力线缆阻燃等级偏低引发的火灾占相当大的比例,电力线缆在火灾时具有蔓延快、扑救难、产生二次危害以及恢复时间长等特点,会给国民经济及人民群众的生命财产带来巨大的损失.通过民用建筑中具体工程设计实例,拟建计算表格对线缆非金属含量计算及阻燃等级选择问题进行探讨,可为电气设计人员提供参考.
Abstract
With the rapid development of economy in our country,the fire caused by electricity increases year by year,in which the fire caused by low flame-retardant grade of power cable accounts for a considerable proportion,the characteristics of power cable in fire,such as rapid spread,fire fighting,secondary damage and long recovery time,will bring huge loss to national economy and People's life and property.The paper discusses the calculation of non-metal content of cable and the selection of flame-retardant grade through the concrete engineering design examples in civil buildings.
