Abstract

The invention discloses a flame-retardant cable, which comprises a core material, wherein the core material is formed by twisting an iron-based alloy wire, a copper-based alloy wire and an aluminum-based alloy wire; a flame-retardant filler coats the outside of the core material; a damp-proof layer is arranged on the outer side of the flame-retardant filler; a lightweight woven mesh coats the outside of the damp-proof layer; and an insulating layer is arranged on the outer side of the lightweight woven mesh. By means ofthe iron-based alloy wire, the copper-based alloy wire and the aluminum-based alloy wire in the flame-retardant cable, the strength requirement and the conductivity requirement of the core material are met; the flame-retardant filler can ensure fire-resistant and flame-retardant characteristics in the working process; and the product cost can also be reduced.
