The invention discloses a waterproof and reinforced low-voltage fireproof cable. Several fan-shaped tinned copper wire conductors are symmetrically arranged around the periphery of a galvanized steel wire central conductor to form a circular inner conductor. The galvanized steel wire central conductor is coated with a first EVA. Adhesive layer, the inner conductor is covered with high temperature fireproof tape wrapping inner layer, aramid fiber twist wrapping layer, high temperature fireproof tape longitudinal wrapping outer layer, second EVA adhesive layer, XLPE insulating layer, iron powder polyethylene compound Resin wrapping, metal shielding layer, third EVA adhesive layer, butyl rubber moisture barrier, high temperature glass fiber tape wrapping, nylon anti-corrosion layer and low smoke halogen free polyolefin sheath. The cable has excellent waterproof and fireproof performance, better fire resistance and flame retardancy, excellent insulation performance, stable electrical shielding performance, better adaptability to the laying environment, and improves the safety and reliability of the cable. |
