Abstract
The utility model relates to a medium-voltage fire-resisting armored cable, which comprises three conductors with insulation layers. Each insulation layer is the cross-linked polyethylene insulation layer; a conductor shielding layer is arranged between each conductor and the insulation layer; the insulation layer of each conductor is externally provided with an insulation shielding layer; the insulation shielding layer is externally wrapped with a copper belt; the three conductors are sequentially and externally wrapped with coating belts, an oxygen-separation layer, an armored layer and a sheath; an inorganic paper filling rope is arranged between the three conductors and the coating belts; the steel belt wrapped with non-woven fabrics is arranged between the armored layer and the sheath; the coating belts comprises a mica belt and a ceramic composite silicone rubber belt; the oxygen-separation layer is the low-smoke halogen-free polyolefin oxygen-separation layer; the armored layer is either a galvanized steel wire armored layer or a stainless steel wire armored layer; and the sheath is the low-smoke halogen-free polyolefin sheath. The medium-voltage fire-resisting armored cable has the advantages that the fire-resisting performances are good; the mechanical strength of the cable is high; and the service life is long.
