Abstract：Five combustion tests are conducted to compare the integrity of general power cables,organic insulated fire‑resistant cables with the same mica tape and different numbers of insulating layers,magnesium oxide insulated fire‑resistant cables,flexible mineral insulation fire‑resistant cables,and cables with the same structure and different specifications and models under temperature rise condition in case of fire,the cable type,the law of power supply time and operating data of power supply line for firefighting equipment in buildings under actual load fire condition are analyzed and discussed.

Key words：fire distribution line;line integrity;fire‑resistant cable;combustion test;organic insulated fire‑resistant cable;magnesium oxide insulated fire‑resistant cable;flexible mineral insulation fire‑resistant cable;fire‑resistant cable tray

摘　要：通过5次燃烧试验，将普通电力电缆、相同云母带不同层数绝缘的有机绝缘类耐火电缆、氧化镁绝缘耐火电缆、柔性矿物绝缘类耐火电缆和同结构不同规格型号的电缆等在火灾升温条件下对比试验后的线路完整性，分析、探讨建筑物中消防设备供电线路在带实载受火条件下电缆类型与供电时间的规律及运行数据。
