Abstract In this paper，continuous power supply time requirements to different kinds of fire control electrical equipments are cited from the related codes；fire-resistant properties of cables in different laying modes are analyzed. It is proposed that different fire-resistant classes of cables and the relevant laying modes shall be respectively adopted for different buildings and various fire control electrical equipments，which shall be determined in the revision of related codes. 

Key words Fire control electrical equipments  Continuous power supply time Line laying Fire-resistant properties Cables with different fire-resistant classes

摘 要 列举有关规范对各类消防用电设备火灾时的连续供电时间要求，分析了各种敷设方式下电缆的耐火特性，提出应根据不同建筑物和各类消防用电设备分别选用不同耐火等级的电缆并确定其敷设方式，建议在相关规范修订时予以明确。
