The defects of traditional fireproof cable, the mineral insulation copper metal jacket structure of generally use, this cable are fatal be Production installation over long distances can not be completed, flexibility is poor.
Utility model content
The shortcomings that in above-mentioned existing production technology, the utility model provide a kind of fire prevention open armoring optical fiber compound electric Cable, it has good fire protecting performance, environmental protection and economy, can realize the characteristics of producing over long distances.
One kind fire prevention open armoring optical fiber composite cable, including at least two insulated wire cores, light unit, inorganic fire layer, high resistant Fire band and fireproof metal sheath;The light unit is arranged on cable center, the insulated wire cores and the light unit twisted synthesizing cable Core;The inorganic fire layer is extruded in the outside of the insulated wire cores and the light unit;
The wrapped high fire-retardance band outside the inorganic fire layer;
The fireproof metal sheath formed outside the high fire-retardance band using armouring;
Described insulated wire cores set gradually conductor, inorganic compounding insulating barrier from inside to outside.
Further, the conductor is twisted by copper or aluminium alloy molded line.
Further, the inorganic compounding insulating barrier includes the wrapped fire-resistant isinglass belt outside conductor and is extruded in fire resisting Ceramic silicon rubber material outside mica tape.
Further, described inorganic fire layer is extruded by inorganic fire mud forms.
Further, the fireproof metal sheath buckles armouring through interlocking for 5154 aluminum alloy strips of high intensity and formed.
Further, the light unit quantity is 1~2.
Further, described light unit sets gradually optical cable and optical fibres, sheath, enhancement layer, outer jacket from inside to outside.
Further, the enhancement layer is made up of aramid fiber.
Further, the insulated wire cores quantity is 2~5.
The beneficial effect that the utility model is reached:The utility model is twisted using copper or aluminium alloy type cable architecture, conductor External diameter reduces, and saves various material costs outside conductor;Design wrapped fire-resistant isinglass belt outside the conductor used and extrude ceramic SiClx Elastomeric material, the flexibility of the structure is good, heat resistance is high;And inorganic fire mud is extruded outside cable core gap and cable core, it is this Material drastically solidifies in the case of preheating or heating, into stone-like lump and do not burn, outside flame can not be burnt to cable Inside, there is good flame-retardant performance;The outside of the cable uses interlocking open armoring structure, and first is easy to cable radiating, Second saves copper resource and cable cost, and the aluminium alloy of the 3rd this interlocking sheathed structure, intensity is high, can play good protection The effect of cable core, due to being metallic article, outside is without nonmetal object, more difficult burning, while light unit in this armouring knot In structure, other armouring materials can be reduced, reach the effect for avoiding mechanical damage.
