Abstract
The utility model discloses an anti-impact fire-resistant power cable, which comprises a cable core, the cable core comprises a wire core and a filling layer, the wire core and the filling layer are formed through extrusion, the outside of the cable core is provided with a wrapping layer, the outside of the wrapping layer is provided with an inner sheath, the outside of the inner sheath is provided with an armor layer, and the outside of the armor layer is provided with an outer sheath. The power cable comprises an armor layer, a composite protection layer is arranged outside the armor layer, an outer sheath is arranged outside the composite protection layer, the armor layer, the composite protection layer and the outer sheath are formed through extrusion, the composite protection layer of the power cable is of a double-layer structure composed of ceramic silicone rubber and nitrile rubber, the ceramic silicone rubber has good fire-resistant and flame-retardant performance, and the nitrile rubber has good fire-resistant and flame-retardant performance. The nitrile rubber has good buffering performance and plays a role in protection when the cable is impacted by external force, the arch-shaped sheets are embedded in the nitrile rubber and deform when being impacted by the external force, the impact force is buffered and released, and the impact resistance of the cable is further improved.
