Description
Technical field
The utility model relates to a kind of track answering machine data transmission cable.
Background technology
In recent years, be widely used in main busy trunk lines, obtain good effect, receive user's welcome and affirming of authorities from the different kinds of railways signal new equipment of external introduction and domestic development, new equipment.The practical demand that signal system develops has been satisfied in the exploitation of dot-mode transponder data transmission cable, has broad application prospects at railway, subway.Point type equipment provides the train control system information transfer channel; It is the advanced technology of external train control system; Study external dot-mode transponder data transmission cable; Exploitation is fit to the dot-mode transponder data transmission cable of China's national situation, and to improving China's technical equipment, improving the transport power capacity has realistic meaning preferably.
Dot-mode transponder data transmission cable is applied to track circuit point type responder system; Be used for the connection between dot-mode transponder and surface units (LEU) the signal controlling equipment; The data message information and the electric energy of transmission automatic block system, train protection system are a kind of enhanced signal copper core cables along track laying.It can use with non-electrified different sections in railway electrification.The insulation resistance of dot-mode transponder data transmission cable is high, dielectric voltage withstand intensity is high; Has under high frequency transmission (high-transmission frequency can reach 1.8MHz) undistorted, the undistorted characteristic of signal; Product adopts the aluminium sheath structure; Have good capability of electromagnetic shielding, can be used for the strong section of electric railway or electromagnetic interference.Along with the continuous increase of railway traffic flow, track transponder cable plays an important role aspect the tight security keeping.
Existing track answering machine data transmission cable (LEU-BSYL, LEU-BSYA type), it is added by cable core and the wrapped band (layer 2-3), the aluminium-plastic tape that are coated on the cable core periphery, and polyethylene insulating barrier, aluminium sheath add the polyethylene bed course, two steel band is wrapped and the linea low density outer jacket is formed.In its cable core stranding; Owing to want wrapped multi-layer tapes; Cause speed of production and equipment to be restricted, and wrapped band increased the external diameter and the cost of whole cable core, especially LEU-BSYA type cable is when using aluminium-plastic tape; Its anti-pressure ability is relatively poor, and its antijamming capability under high-frequency does not have the effective of low resistivity material shielding.Because execution conditions such as railway, subway are abominable, high to the cable shield performance requirement, institute thinks the anti-pressure ability and the shield effectiveness of raising cable, improves necessary to the structure of track answering machine data transmission cable satisfying on the basis of electric index.
Summary of the invention
The purpose of the utility model provides a kind of novel track answering machine data transmission cable that improves anti-external interference and influence, raising shield effectiveness.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of track answering machine data transmission cable; Comprise cable core, coat described cable core composite sheath, be coated on the outer outer jacket of described composite sheath, described composite sheath comprises the vertical outer belting layer of described cable core, vertical described belting layer outer copper shield, the wrapped lapping layer outside described copper shield of being wrapped in of being wrapped in.
Preferably, described belting layer is one deck PE belting layer.
Preferably, described copper shield is an embossing copper strips screen.
Preferably, described lapping layer is the polyester belt lapping layer.
Preferably, described cable core comprises many stranded single lines.
Preferably, described single line comprises the insulating barrier of copper conductor, the described copper conductor of coating.
Preferably, described outer jacket comprises aluminium sheath, bed course, dress armour layer, the oversheath that sets gradually from inside to outside.
Because technique scheme utilization; The utility model compared with prior art has advantage: the track answering machine data transmission cable of the utility model has the ability of anti-preferably external interference and influence; Its performance is higher, is applicable to than in the severe construction conditions.
Description of drawings
Accompanying drawing 1 is the structural representation of the track answering machine data transmission cable of the utility model.
In the above accompanying drawing: 1, cable core; 11, single line; 111, copper conductor; 112, insulating barrier; 2, composite sheath; 21, belting layer; 22, copper shield; 23, lapping layer; 3, outer jacket; 31, aluminium sheath; 32, bed course; 33, dress armour layer; 34, oversheath.
Embodiment
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Embodiment one: shown in accompanying drawing 1.
A kind of track answering machine data transmission cable, comprise cable core 1, coat cable core 1 composite sheath 2, be coated on the outer outer jacket 3 of composite sheath 2.
Composite sheath 2 comprises the vertical belting layer 21 outside the cable core 1, vertical copper shield 22, the wrapped lapping layer 23 outside copper shield 22 that is wrapped in outside the belting layer 21 of being wrapped in.Belting layer 21 is one deck PE belting layer 21.Copper shield 22 is an embossing copper strips screen, and this embossing copper strips screen can improve the anti-external interference ability of cable.Lapping layer 23 is a polyester belt lapping layer 23.When in the cable production process, processing composite sheath 2; Because cable core 1 is thinner; General is 9.00mm, indulges bag PE belting layer 21, vertical bag embossing copper strips screen, wrapped polyester belt lapping layer 23 so adopt little shield machine that cable core 1 is once accomplished, and has reduced the extrusion process of composite sheath 2 in the past; Practice thrift the material that uses in the extrusion process, reduced the physical dimension of cable core 1 simultaneously.So not only can not influence the electric property of cable; And practiced thrift material; In cable core 1 band process, also can not receive simultaneously the influence of stranding device rate; Accomplish the production of two procedures (stranding, extrusion molding) in the past at shield machine, and the resistance to compression of cable core 1, shielding properties have all obtained very high improvement.
The foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the utility model.
