The invention discloses a fireproof polyvinyl chloride sheathed cable. The fireproof polyvinyl chloride sheathed cable comprises a conductor and a sheath, wherein the sheath is prepared from the following components in parts by weight: 60 to 80 parts of polyvinyl chloride, 20 to 30 parts of epoxy resin and 10 to 20 parts of hollow polyurethane nano-fiber. The fireproof polyvinyl chloride sheathed cable has the following advantages and effects that the polyvinyl chloride, the epoxy resin and the hollow polyurethane nano-fibers are added into the sheath of the fireproof polyvinyl chloride sheathed cable so that the sheath has higher thermal decomposition temperature and the heat-resisting performance and flame-retarding performance of the polyvinyl chloride are improved; after a fire disaster occurs, the fireproof polyvinyl chloride sheathed cable can still be electrified for certain time, so that the fireproof polyvinyl chloride sheathed cable is convenient for firefighting rescue and has excellent heat-resist
