Description
Technical field
The utility model relates to a kind of optoelectronic composite cable that is used for the air-blown installation fiber unit, and this cable is applicable to the compound transmission field of photoelectricity.
Background technology
Along with the fast development of electric power energy demand, power department is wished by using transducer, gauge table, digital control and analysis tool to reach the purpose of automatic monitoring electrical network, optimization electric network performance; Also wish simultaneously intelligent electric meter as internet router, based on its terminal use, communicate, broadband services or propagation TV signal etc.Thereby cable also proposed in electric energy transmitting the requirement of transmission information that can high-efficiency large capacity, optoelectronic composite cable produces thus.
Existing optoelectronic composite cable is to process compound stranding together by lead and fiber unit to form, and such processing mode easily makes fiber unit stressed and cause the remarkable decline of its transmission performance, therefore production technology is had higher requirement; Simultaneously because the plain conductor Heavy Weight, needed pulling force becomes greatly thereupon in laid processes, because it is bigger to lay pulling force, Chang Yi causes fiber unit stressed excessive and impaired, thereby have a strong impact on the useful life of the transmission quality and the composite rope of light signal, even cause composite rope to be scrapped.
On the other hand; with regard to fibre junction; in the practical wiring engineering; no matter be to adopt the welding mode or by the flange ways of connecting; the fiber optic protection layer that need open stripping is all long; and usually if only shelling length at continuing out of cable is much smaller, existing optoelectronic composite cable causes the waste of plain conductor easily when jointed fiber.In addition, when propping up wire routing, need usually from the main line cable, to divide inconsistent subsequent transmissions unit, if the transmission branch line is more, splicing point also can increase accordingly, this has not only increased later maintaining cost, and fibre junction can cause the decay of transmission signals simultaneously, during the length Distance Transmission, if splicing point is too much, the signal attenuation meeting is very big, and needed relay station is also just many more, and this will increase the cost of cable laying operation.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and proposes a kind of optoelectronic composite cable that is used for the air-blown installation fiber unit, it can not only avoid making fiber unit stressed in stranding and laid processes, and can effectively reduce the splicing point of fiber unit in the difference handshaking procedure, reduce connecting loss, reduce the cost of cable laying operation.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: the oversheath that includes cable core and coating cable core, be laid with insulated conductor in the cable core, its difference is to include in the described cable core air-blowing microtubule, to be used for the air-blown installation to fiber unit.
Press such scheme, be installed on the centre junction member in the described cable core, insulated conductor and fiber unit are uniform along centre junction member periphery.
Press such scheme, described insulated conductor is provided with 1～8, and insulated conductor is made of the plain conductor of coated insulation sleeve pipe; Described air-blowing microtubule is provided with 1～8, and air-blowing microtubule diameter of bore D and fiber unit external diameter (or width) d meet the following conditions: d＜0.95D.
Press such scheme, described air-blowing microtubule endoporus edge circumferentially is provided with the straight trough that axially runs through, and is covered with lubricating layer at air-blowing microtubule bore area, and lubricating layer is made of solid lubricant (for example silicon core), in order to reduce the resistance of air-blown installation.
Press such scheme, between cable core and oversheath, can hold strapping or coat water blocking layer.
Press such scheme, described fiber unit is optical fiber, fibre ribbon or fiber bundle.
Press such scheme, described insulated conductor and air-blowing microtubule be straight laying or stranded laying in oversheath.
The beneficial effects of the utility model are: 1, the mode that is blown into by compressed air after composite rope lays of fiber unit is laid in the cable, therefore be that external force can not have influence on fiber unit in composite rope production process or laid processes, fiber unit lays the back and be in relaxed state in the air-blowing microtubule, no external force effect, information transmission performance and the useful life that can improve composite rope to greatest extent; 2, owing to the fiber unit of air-blown installation can directly be drawn at the branch line parting, thereby can reduce the splicing point of fiber unit in the optoelectronic composite cable laid processes, the signal attenuation that reduction causes because of fiber unit continues, also avoided simultaneously the waste of plain conductor, reduce laid down cost, also be convenient to later maintenance; 3, reduce the processing technology requirement of optoelectronic composite cable, improved the rate of finished products and the production efficiency of product processing.
