Fireproof water-stopping armoured cable for offshore petroleum platform

The utility model provides a fireproof water-stopping armoured cable for an offshore petroleum platform, belonging to the technical field of cables. The fireproof water-stopping armoured cable comprises a cable core and an external protective layer. The fireproof water-stopping armoured cable is characterized in that the cable core is formed by stranding 5 insulating wire cores; the circumference of the insulating wire cores is filled with a non-moisture-absorbing filling rope; the cable core is wrapped by a flame-retarding layer with high-flame-retarding fiberglass; the flame-retarding layer is wrapped by a water-stopping layer with a water-stopping cloth belt; the water-stopping layer is extruded and wrapped by a flame-retarding cross-linked polyalkenes internal protective layer; the internal protective layer is weaved by a galvanized copper wire sheath layer; and the sheath layer is extruded and wrapped by a flame-retarding polyalkenes external protective layer. The section areas of 3 insulating wire cores of the 5 insulating wire cores of the cable core are more than those of the other 2 insulating wire cores. The cable core is formed that a tinning copper conductor is wrapped by a mica tape, and the mica tape is extruded and wrapped by a flame-retarding cross-linked polyethylene inulating layer. The fireproof water-stopping armoured cable has reasonable and simple structure, can be produced and manufactured easily, has stable transmission performance, and good insulating performance, good shielding performance, good water-stopping performance and good flame-retarding performance.
