Abstract

The invention relates to the field of wires and cables and particularly relates to a fire-resistant cable. The fire-resistant cable comprises conductor cores, wherein the number of the wire cores is multiple, a plurality of wire cores are wound together around a heat conduction rod, heat conduction fins are arranged on the heat conduction rods, the number of heat conduction fins is consistent withthe number of the wire cores, the heat conduction fins are arranged between two adjacent wire cores, a mica wrapping tape wraps the wire cores, the other end of each heat conduction fin is tightly attached to the mica wrapping tape, a glass fiber wrapping tape wraps the mica wrapping tape, an insulating layer is arranged outside the glass fiber wrapping tape, an oxygen isolation layer is arrangedoutside the insulating layer, and a waterproof layer is arranged outside the oxygen isolation layer. The cable is good in fireproof performance and simple in structure.
