Abstract：The design requirements for fire resistance parameters of power supply cable for fire protection，the existing differences between domestic and foreign fire‑resistant test standard parameters and the deviations of some designers in the understanding of cable selection are analyzed，the industry is suggested to develop national fire test standards with strong credibility and the designers are also suggested to make design based on current specifications，standards and products.

Key words：power distribution line for fire protection； mineral‑insulated cable；fire‑resistant cable；fire test standard；organic insulated cables；flexible mineral‑insulated cable；fire resistance temperature；fire resistance time

摘　要：分析设计对消防供电电缆耐火类参数的要求与目前国内外耐火试验标准参数值的差别，以及部分设计人员在电缆选择认识上的偏差，建议行业尽快编制公信力强的国家级耐火试验标准，也建议设计人员应该基于现行规范、标准和产品，做到设计有据。
