Abstract

The utility model discloses a cable having an AC rated voltage of 1kV and below used for civil and architectural engineering. The cable comprises a group of power cable cores, a zero line, an earth wire, flame retardant fillers, and a flame retardant wrapping tape. The flame retardant fillers are disposed among the power cable cores, the zero line, and the earth wire. During the cable forming process, the flame retardant wrapping tape is wrapped by a corrugated-shaped coiled pipe protective layer, an outer side of which is provided with a corrugated-shaped elastic sheath. The elastic sheath is a metal sheath formed by stainless steel bands made of non-magnetic materials. According to the utility model, the stainless steel corrugated-shaped coiled pipe and the elastic sheath are adopted, the cable can bear a high-intensity mechanical bearing force and an instantaneous impact force, therefore the flexibility of the cable is better than that of the cable adopting the steel band armoring way, and the anti-mechanical pressure of the pipe-shaped structure is better than the mechanical bearing force of the band gap winding structure. By using the incombustibility of the stainless steel material, even when the cable is under an overload operation condition, a short circuit condition, or a spontaneous combustion, the combustion of the surrounding media cannot occur.
