Abstract
The synthesis cable is suitable to digital signal transmission and communication at railway stations, section main line, electrization railway or non electrization railway. The core of cable is composed of digital shielded four-wire group and insulated core. There are liner layer, aluminum sheath, inner sheath, armour layer, outer sheath from inner to outer in sequence outside core of cable. Characters are that an optical fiber is included inside core of cable. The fiber is arranged in vacant space among digital shielded four wire groups. Thus, optical fiber is not needed to construct all alone. Advantages are: economical efficiency, easy managing, protecting and troubleproof shooting.
Description
Technical field
The present invention relates to a kind of railway numeral inner shield optoelectrical cable, be applicable to the digital data transmission and the communication of railway station, interval main line, electrification/non-electrified circuit.
Background technology
Continuous development along with China Railway, the needs of railway signal transmission line and railway communication circuit are also in continuous increase, original circuit can not satisfy the demands, but on original basis, set up new line, both set up the restriction in space, and set up the restriction of requirement again and can bring adverse effect safeguard, overhaul in the future.In the railway signal transmission course, especially in forceful electric power gasification railroad section, the transmission of signal always is subjected to electromagnetic influence, has reduced transmission quality, influences the normal operation of railway transportation.In order to address this problem, generally be stranded, thereby reach the purpose of improving transmission quality, but effect not very remarkable by adopting different twisting pitch that digital quad is carried out.
Chinese patent application 94108245.8 discloses a kind of cable with shielding construction that is used for the transmission differential logical signal and Chinese patent application 99805738.X and discloses family cable under a kind of non-woven shielding that is easy to be connected on the standard connector and Chinese patent application 99207571.8 and disclose the railway signal cable that a kind of shielding protection layer is continuously extruded aluminum pipe; more than these patent application technical schemes are solved is to coming from the interference of electromagnetic field of cable outside, and do not reach the function that cable also has optical fiber communication.
Deficiency at aforementioned these patented technology schemes, Chinese patent application 03236668.X has introduced a kind of Unit Shielding Rail Road Digital Signal Cable, its technical problem to be solved is the crosstalk attenuation problem of railway signal cable high frequency quad between the forceful electric power gasification zone, promptly prevents phase mutual interference between each line group of inside of railway digital signal cable.Equally disclose and how to make this cable both have a digital data transmission, have the technical pattern enlightenment of optical fiber communication again concurrently.So, present situation is: in order to satisfy the requirement of ever-increasing railway signal transmission line and railway communication circuit, have to still adopt separately that the fiber plant communication line adapts to, thus bring space when setting up whether to permit, cost is high and uneconomical, manage and protect big, the problem being unfavorable for overhauling of difficulty.
Summary of the invention
Be to solve foregoing problems, the object of the present invention is to provide a kind of need not by separately separately erecting optical cables and can satisfy railway signal transmission line and railway communication circuit with the incompatible requirement of actual needs, can embody economy, alleviate the digital inner shield optoelectrical cable of the railway of managing and protecting difficulty and being beneficial to maintenance.
For achieving the above object, technical scheme provided by the present invention is: a kind of railway numeral inner shield optoelectrical cable, it comprises the cable core that is made of numeral shielding quad 8 and insulated wire cores 1, the inner covering 3 outside cable core, the aluminium sheath 4 outside inner covering 3, the inner sheath 5 outside aluminium sheath 4, the armour 6 outside inner sheath 5, the oversheath 7 outside armour 6, be characterized in: described cable core also includes an optical cable unit 2, and this optical cable unit 2 is arranged in the digital spatial domain that shields between the quad 8.
Optical cable of the present invention unit 2 comprises the loose tube fiber 13 of a reinforcement 17 and at least 4 groups 2～4 cores, every group of loose tube fiber 13 is contained in respectively in each loose sleeve pipe 16, be filled with in the hole between loose tube fiber 13 and loose sleeve pipe 16 and fill fine cream 14, and, each the loose sleeve pipe 16 that holds respectively behind the loose tube fiber 13 is stranded on the reinforcement 17, and silk ribbon 15 is pricked around being covered with in its outside.
The internal diameter of each loose sleeve pipe 16 of the present invention respectively is 1.95～2.05mm, and wall thickness respectively is 0.25～0.35mm.
Each loose sleeve pipe 16 of the present invention has different colors each other.
Each loose sleeve pipe 16 stranded twisting pitch on reinforcement 17 of the present invention are 74.5～75.5mm.
Reinforcement 17 of the present invention is a wire.
Wire of the present invention is the phosphatization steel wire, and this phosphatization steel wire outer surface squeezes and is covered with the thick high density PE of 0.2mm.
The layer structure of numeral shielding quad 8 of the present invention is followed successively by polyester twining package tape 13, embossing copper strips screen 12, PE sheath 11.
Each loose sleeve pipe 16 of the present invention has color, and the color between each loose sleeve pipe 16 is different.
The present invention has been owing to constituted optoelectrical cable to adding optical cable unit 2 in original cable core that is made of numeral shielding quad 8, insulated wire cores 1, thereby leans on separately erecting optical cables to solve railway signal transmission line and railway communication circuit with the incompatible problem of actual needs need not resemble in the past; Have economy, because no matter independent erecting optical cables is the cost that is brought from the requirement of optical cable self structure, it is all much higher more than optoelectrical cable provided by the invention still to set up the annex cost; Help concentrating and manage and protect and make things convenient for maintenance.
