Abstract：This paper briefly introduces the classification,production process,and cable construction of aluminum alloy fire‑resistant cables. Based on an analysis of the fire resistance test reports and test bases of aluminum alloy fire‑resistant cables,the characteristics of aluminum alloy fire‑resistant cables are compared with those of copper‑core fire‑resistant cables,and the possibility of the application of aluminum alloy fire‑resistant cables in civil building engineering is discussed and studied.

Key words：wire and cable;aluminum alloy fire‑resistant cable;aluminum alloy flexible mineral‑insulated power cable;fire resistance;firefighting equipment;line integrity test;burning behavior grading;fire‑resistance duration
