Abstract

The utility model relates to a fire resistance photoelectric composite cable which comprises an outer sheath and a photoelectric composite cable core. The cable is characterized in that the photoelectric composite cable core is coated with a water blocking layer and a fire resistance layer; and the fire resistance layer is coated with a steel plastic composite tape armor layer and a low smoke halogen-free outer sheath. According to the utility model, the cable has the advantage of strong fire resistance, and can ensure that luminous flux and power transmission of the composite cable core are remained during the periods of high temperature burning and fire stopping cooling; when the ceramic sulfuration silicone rubber fire resistance layer burns, the ceramic sulfuration silicone rubber fire resistance layer changes into a hard ceramic casing in a very short period of time to form a great heat insulating layer to prevent flame from continuing to burn; the longer the burning time is, the more obvious ceramizationceramizationceramization is; the fire resistance temperature is up to 1200 DEG C; the steel tape enables the composite cable after burning to remain quite high strength and stiffness; and the fire resistance photoelectric composite cable has the advantages of reasonable structure arrangement, convenient laying and use, small laying space and low cost, and is especially suitable for being used by a complicated environment in a subway tunnel or an important public place with a fire resistance requirement.

Description

A kind of fire-resistant optoelectronic composite cable
Technical field
The utility model relates to a kind of fire-resistant optoelectronic composite cable that can be used for the subway base station, belongs to the optical communication transmission technique field.
Background technology
Existing city underground indoor wireless soverlay technique mostly adopts full optical cable transmission, two kinds of mains-supplied patterns that the remote equipment electricity consumption is generally adopted power taking nearby or by an other private cable, powered.Because environment in subway tunnel is more complicated, adopt mains-supplied to have problems,, in order addressing the above problem, to adopt private cable to carry out direct current and far supply the confession electrical transmission of base station.For this reason, need to carry out laying of optical cable and two cables of cable in subway tunnel, not only laid down cost is high for this, lays institute and takes up space greatly, and, due to the fire resistant flame retardant poor performance of cable, brings very large potential safety hazard for the operation of subway.
Summary of the invention
The technical problems to be solved in the utility model is to provide the optoelectronic integration that a kind of structure arranges rationally, fire resistance is strong fire-resistant optoelectronic composite cable for the deficiency that above-mentioned prior art exists.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include oversheath and optoelectronic composite cable core, it is characterized in that at optoelectronic composite cable core outer cladding water blocking layer and flame retardant coating flame retardant coating outer cladding composite steel-plastic belt armour and low smoke and zero halogen oversheath.
Press such scheme, be laid with non-metal reinforcement member between flame retardant coating and composite steel-plastic belt armour.
Press such scheme, described optoelectronic composite cable core is the layer stranded optical/electrical composite cable core.
Press such scheme, described layer stranded optical/electrical composite cable core includes central reinforce member, and stranded jacket insulation feed line and the loose sleeve pipe of having or not of central reinforce member periphery, be laid with fiber unit in loose sleeve pipe.
Press such scheme, described have three strands without the jacket insulation feed line, and wherein one is ground wire, and two strands is power line, without the core conductor of jacket insulation feed line by the coated insulation layer, forms, and described insulating barrier is the low smoke and zero halogen insulating barrier.
Press such scheme, described loose sleeve pipe contains water-blocking component, and described water-blocking component is fine cream, water blocking yarn, waterproofing rope or the water-proofing powder of blocking water.
Press such scheme, described flame retardant coating is formed by ceramic sulphurated siliastic composite band voluble wrapping.
Press such scheme, described low smoke and zero halogen oversheath and insulating barrier are made by low-smoke halogen-free polyolefin or other macromolecular material with anti-flaming function.
Press such scheme, described non-metal reinforcement member is glass fiber yarn, glass fiber tape, aramid yarn or aramid belt.
Press such scheme, described central reinforce member is nonmetal central reinforce member.
The beneficial effects of the utility model are: 1, fire-resistant optoelectronic composite cable not only arranges ceramic sulphurated siliastic flame retardant coating, and be provided with the low smoke and zero halogen oversheath, make and the utlity model has very strong fire resistance, guarantee compound cable core during high-temp combustion and the cooling period of ceasing fire still keeps light transmittance and electric power transfer; When 2, ceramic sulphurated siliastic flame retardant coating burns, change into the hard ceramic package of one deck within very short time, form the good thermal insulation layer of one deck, stop burning away of flame, and burning time is longer, temperature is higher, ceramic is more obvious, can fire-resistantly reach more than 1200 ℃; Simultaneously, steel band makes composite rope keep afterwards quite high strength and stiffness in burning; Above-mentioned 2 light transmittance and electric power transfer of effectively having guaranteed composite rope, block and delay the burning of composite rope ecto-entad, further strengthened the fire resistance of composite rope; 3, structure arranges rationally, lays with easy to use, lays space little, and cost is low, is particularly useful for the use of complex environment in subway tunnel.
Description of drawings
Fig. 1 is the radial section figure of an embodiment of the utility model.
Embodiment
Further describe embodiment of the present utility model below in conjunction with accompanying drawing.
embodiment as shown in Figure 1, for the fire-resistant optoelectronic composite cable of a kind of layer-twisted type list sheath list armouring, comprise the layer stranded optical/electrical composite cable core that is positioned at the composite rope center, there is nonmetal central reinforce member 7 at described layer stranded optical/electrical composite cable core center, nonmetal central reinforce member is the glass fibre central reinforce member, glass fibre central reinforce member periphery is stranded has three without jacket insulation feed line and a loose sleeve pipe, form without the core conductor 5 of jacket insulation feed line by coated insulation layer 6, described insulating barrier is the low smoke and zero halogen insulating barrier, made by low-smoke halogen-free polyolefin, three without in the jacket insulation feed line, one is ground wire, two strands is power line, be provided with fiber unit 9 in pine sleeve pipe 8, described fiber unit is optical fiber, fiber bundle or fibre ribbon, and described loose sleeve pipe contains water-blocking component 10, and described water-blocking component is the fine cream that blocks water, and forms half dry type layer-twisted type cable core.Optoelectronic composite cable core outer cladding water blocking layer 11, water blocking layer consists of water blocking yarn or waterstop; At water blocking layer outer cladding flame retardant coating 4, described flame retardant coating is formed by ceramic sulphurated siliastic composite band voluble wrapping; Be outside equipped with one deck non-metal reinforcement member 3 at flame retardant coating, non-metal reinforcement member is glass fiber yarn, glass fiber tape, aramid yarn or aramid belt; At non-metal reinforced layer outer cladding one deck composite steel-plastic belt armour 2; Extrusion molding one deck low smoke and zero halogen oversheath 1 outside composite steel-plastic belt, the low smoke and zero halogen oversheath is made by low-smoke halogen-free polyolefin.
