Description
Technical field
The utility model relates to a kind of optical cable, and particularly a kind of offshore drilling platforms is used flame-proof cable.
Background technology
The offshore drilling platforms operation area, many high temperature inflammable gas, environment is abominable and dangerous, breaking out of fire easily.When breaking out of fire, require optical cable can continuous firing under 1000 ℃ the condition more than 3 hours, existing offshore drilling platforms optical cable can't satisfy the abominable operating environment of platform, especially under fire condition, can't satisfy the signal transmission demand.
The utility model content
The purpose of the utility model is, overcomes the problem that exists in the prior art, provides the offshore drilling platforms that a kind of intensity is high, fire performance is good to use flame-proof cable.
For solving above technical matters; A kind of offshore drilling platforms that the utility model provided is used flame-proof cable; Cable core comprises three fiber cores, three filled cores and a strengthening core; Said strengthening core is positioned at the center of cable core, and said three fiber cores and three filled cores are distributed in the periphery of said strengthening core, said three adjacent arrangements of fiber cores; The center of said strengthening core is stranded steel wire, and the periphery of said stranded steel wire is extruded with insulation course; The center of said fiber cores is an optical fiber, and the periphery of said optical fiber is with pipe, and the periphery of said pipe is surrounded with the fiber cores fire-resistant isinglass belt; The center of said filled core is a packing material, and the periphery of said packing material is provided with rubber sheath; The periphery of said cable core is surrounded with the cable core fire-resistant isinglass belt; The periphery of said cable core fire-resistant isinglass belt is extruded with the Halogen inner liner; The periphery of said Halogen inner liner is provided with zinc-coated wire braiding armor, and the periphery of said zinc-coated wire braiding armor is extruded with oversheath.
With respect to prior art, the utility model has been obtained following beneficial effect: strengthening core can improve the resistance to tension of whole optical cable, and stranded steel wire periphery realizes insulation through insulation course and fiber cores; Filled core is set makes whole cable core rounding, the rubber sheath of packing material periphery can prevent the packing material distortion; The periphery of optical fiber is with pipe and plays protective action, and three fiber cores are surrounded with the fiber cores fire-resistant isinglass belt respectively and form flame retardant coating separately; The wrapped cable core fire-resistant isinglass belt of whole cable core periphery forms outer flame retardant coating, has guaranteed the refractory ability of optical cable.
