The classification and test standards for fire resistance of different wires and cables are analyzed and compared,and existing problems about and suggestions for the selection of fire resistance category in design standards are proposed.The severity of fire in buildings is closely related with the scale,function and purpose of buildings.The continuous power supply time of firefighting electrical equipment varies with buildings,the distribution and control lines of firefighting equipment shall meet the requirements for continuous power supply for buildings within the duration of fire,and the selection of fire resistance of wires and cables shall match the firefighting equipment.
