Description
Technical field
This utility model relates to a kind of signal and data cable, particularly relates to a kind of beacon for rail transportation cable, belongs to
In technical field of electric wires and cables.
Background technology
Beacon for rail transportation cable, for surface beacon transponder and line side electronic device unit connecting line, constitutes independent
Control system, the data-transformation facility between train and track can be realized, play the run location that can be accurately positioned train
And traffic direction, measure the speed of service etc. of train, it is achieved the transmission of various message informations.The quality of beacon for rail transportation cable
Directly influence the quality of signal transmission.Such cable is to be laid between two guide rails, when train is through out-of-date, due to strong
Vibration, there is the fracture of conductor part generation a part or whole part in the like product of existing market.Cable is in construction and installation process simultaneously
In, cable connector processes inconvenience, and dielectric layer easily bonds with insulating barrier, causes easily hindering conductor when processing end.
Utility model content
This utility model is for avoiding the weak point existing for above-mentioned prior art, it is provided that a kind of beacon for rail transportation electricity
Cable so that it is not only there is the function of data message and signal, and can effectively electromagnetism interference, anti-vibration, meet track traffic letter
The equipment connecting line requirement of number system electrical.
This utility model solves technical problem and adopts the following technical scheme that
Being structurally characterized in that of this utility model beacon for rail transportation cable: in described cable, conductor is to use multiply annealed copper wire
Stranded form, described conductor extrudes cross-linked type polyethylene insulating barrier and constitutes insulated wire cores；Two insulated wire cores twisted synthesizing cables
Core, sets gradually on described cable core and extrudes the dielectric layer of formation, metal composite screen layer, extrudes plastics and constitute inner cushion layer, no
Rust steel wire braid and extrude plastics constitute outer jacket.
The construction features of this utility model beacon for rail transportation cable lies also in: described conductor is seven a diameter of 0.20mm
Copper wire " 1+6 " structure stranded form, the elongation at break of copper wire is 22%～25%；
The construction features of this utility model beacon for rail transportation cable lies also in: the appearance at described insulating barrier applies organic
Silicone oil.
The construction features of this utility model beacon for rail transportation cable lies also in: described dielectric layer is linear low density polyethylene
The tubular structure that alkene material extrudes.
The construction features of this utility model beacon for rail transportation cable lies also in: metal composite screen layer is by tinned copper wire
Being knitted to form as weaving internal layer, the appearance at braiding internal layer indulges bag embossing copper strips.

Low Density Polyethylene or HDPE high density polyethylene (HDPE) are that material extrudes and forms.
Compared with the prior art, this utility model has the beneficial effect that:
This utility model not only has the function of data message and signal, and has good electromagnetism interference, anti-purple
Outside line and anti-shake performance；It fully meets rail traffic signal system electrical equipment even in bending property and electric property
Wiring requirement.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Label in figure: 1 conductor, 2 insulating barriers, 3 dielectric layers, 4 metal composite screen layers, 5 inner cushion layers, 6 stainless steel silk braidings
Layer, 7 outer jackets.
Detailed description of the invention
Seeing Fig. 1, the version of the present embodiment middle orbit traffic beacon cable is:
In cable, conductor 1 is to use that multiply annealed copper wire is stranded forms, and extrudes cross-linked type polyethylene insulating barrier 2 on conductor 1
Constitute insulated wire cores；Two insulated wire cores are twisted into cable core, set gradually that to extrude the dielectric layer 3 of formation, metal multiple on cable core
Close screen layer 4, extrude plastics composition inner cushion layer 5, stainless steel silk braid 6 and extrude plastics composition outer jacket 7.
In being embodied as, corresponding setting also includes:
Conductor 1 is that the copper wire of seven a diameter of 0.20mm is stranded to be formed, and uses the regular lay configuration of " 1+6 ", Ke Yiyou
Effect improves flexibility and the stability of conductor structure, and the elongation at break selecting copper wire is 22%～25%, increases conductor antivibration
Cutting capacity.
Appearance at insulating barrier 2 applies organic silicone oil, can be prevented effectively from insulating barrier 2 and mutually bond with dielectric layer 3, it is simple to
The process of cable construction joint.
The tubular structure that dielectric layer 3 extrudes for linear low density polyethylene material, the tubulose rigid structure formed is entered
One step enhances the antivibration cutting capacity of conductor, protects insulated wire cores, and is avoided that between insulating barrier 2 generation bonding, the most also
Play longitudinal water-proof function.
Metal composite screen layer 4 is to be knitted to form as weaving internal layer by tinned copper wire, and the appearance at braiding internal layer is indulged bag and rolled
Stricture of vagina copper strips, the anti-electromagnetic interference performance of this version is strong, does not affect the bending property of cable, screening factor under its 50Hz simultaneously
It is not less than 0.9.
Outer jacket 7 is to extrude with black LLPE linear low density polyethylene or HDPE high density polyethylene (HDPE) for material to form,
It is waterproof, anticorrosion, anti-ultraviolet, and accommodative ability of environment is strong, can meet the requirement of product adaptation complex environment.
