摘　　要：防火与耐火电缆主要用于超高层建筑、大型公共建筑、一类建筑等有较高消防要求的场所,在火灾时为消防电气设备设施提供电力,执行控制、通讯等功能。在设计选型时,应根据建筑耐火极限、物品的火灾危险等级和火灾持续时间等因素综合考虑并选择对应耐火等级的电缆。对当下主流防火耐火电缆的种类、结构和试验方法进行对比分析,结合电缆在建筑消防领域和消防用电设备中的应用,对选型进行优化分析。Fire-proof and fire-resistant cables are mainly used in super high-rise buildings,large public buildings,first-class buildings and other places with high fire protection requirements.In the event of fire,they provide power for fire-fighting electrical equipment and facilities,and perform functions such as control and communication.In the design and selection,the cable with the corresponding fire resistance level should be comprehensively considered and selected according to factors such as the fire resistance limit of the building,the fire hazard level of the item,and the fire duration.This paper compares and analyzes the types,structures and test methods of the current mainstream fire-resistant and fire-resistant cables,and optimizes the selection based on the application of cables in the field of building fire protection and fire-fighting electrical equipment.
