Summary:A halogen-free low-smoke fireproof power cable comprises metal bare wires (1). The metal bare wires (1) are wrapped by a fireproof mica tape (2) in an overlapped and wound way. The fireproof mica tape (2) is wrapped by a crosslinking polyethylene insulating layer (3). The crosslinking polyethylene insulating layer (3) is wrapped by a glass fiber (4) in a wound way. The glass fiber (4) is further wrapped by a halogen-free low-smoke polyolefin sheath (5). The power cable which has good fireproof performance can protect life safety of trapped persons on a fire hazard site and increase the escape probability of the trapped ones on the fire hazard site.
