Abstract
The invention relates to the technical field of wires and cables, and particularly discloses a moisture-proof, fire-proof and scratch-resistant wire and cable with a three-layer protection structure, which comprises an insulating outer layer, a heat-resistant middle layer is arranged in the insulating outer layer, a waterproof inner layer is arranged in the heat-resistant middle layer, and a plurality of sleeves are movably connected in the waterproof inner layer in a penetrating manner. A plurality of optical fibers are arranged in the sleeves, reinforcing cores are movably connected among the sleeves in a penetrating manner, a filling layer is arranged between the waterproof inner layer and the sleeves, the insulating outer layer comprises an outer sheath, an insulating coating and a polyamide film, the insulating coating is arranged on the outer surface of the polyamide film in a sleeving manner, and the outer sheath is arranged between the outer sheath and the insulating coating. The outer surface of the insulating coating is sleeved with the outer sheath, and the outer surface of the heat-resistant middle layer is sleeved with the polyamide film. The problems that a traditional wire is large in threading resistance, an insulating layer is damaged, moisture and water are not prevented, and short circuit tripping is likely to happen can be solved, and the insulating performance of the wire can be greatly improved.
