NOVELTY - Impact-resistant and flame-retardant cable comprises an insulated core, an insulating layer, an aluminum-plastic composite tape isolation layer, a flame-retardant layer and a protective layer. The gap between the insulated wire cores is provided with a flame retardant filling material, the outside of the insulated wire cores is covered with an insulating layer, and the outer side of the insulating layer is sequentially covered with an aluminum-plastic composite tape isolation layer, a flame retardant layer and a protective layer. The insulating layer is a mineral insulating layer, and the flame-retardant layer is a mica tape with 4-7 layers. USE - Impact-resistant and flame-retardant cable. ADVANTAGE - The cable has flame retardant filling material provided in the space between the insulated wire cores, and the outer side of the insulating layer is sequentially coated with an aluminum-plastic composite tape isolation layer, a flame retardant layer and a protective layer, the insulating layer is a mineral insulating layer, and the flame-retardant layer is a mica tape, and the impact strength and flame-retardant performance are significantly improved, and the service life of the cable is prolonged.
