Abstract
The utility model discloses a two-core data transmission cable of a responser, and the two-core data transmission cable is characterized in that a conductor adopts a single strand flexible copper wire, and a cross linked polyethylene (XLPE) insulation layer is extruded on the conductor to form insulation wire core; two insulation wire cores are twisted to a pair-twist group, the cable cores are sequentially provided with a polyester ribbon, a tinned copper wire braided layer and a total shielded layer which is formed by longitudinally wrapping an aluminum-plastic composite ribbon, which are overlapped and wound as well as an outer jacket layer which is formed by extruded polyethylene plastic, and a drain wire is arranged inside the tinned copper wire braided layer. The two-core data transmission cable has a function for transmitting message data information and electric power, and has advantages of electromagnetic interference resistance, high insulation resistance, high pressure resistant strength, non-distortion of transmission signals under high frequency, non-falsification and the like.
Description
Technical field
The utility model relates to a kind of signal and data cable, relates in particular to a kind of transponder two core data cables, belongs to technical field of electric wires and cables.
Background technology
The fast development of electrified track traffic, the great development that has brought the traffic technique engineering.Transponder and LEU LEU are one of components and parts important in the track traffic control system, and connection lead therebetween need have the function of transmitting message data information and electric energy.According to the requirement of environment for use, require the insulation resistance of cable high, proof voltage intensity is high, under the high frequency transmission signals undistorted, do not distort, high-transmission frequency can reach 1.8MHz.Existing transponder two core data cables can not satisfy the demand of the use of control system.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point; A kind of transponder two core data cables are provided; Make it not only have the function of transmitting message data information and electric energy; And can resist that electromagnetic interference, insulation resistance are high, compressive resistance is high, under high frequency transmission signals undistorted, do not distort.
The utility model adopts following technical scheme for the technical solution problem:
The design feature of the utility model transponder two core data cables is that conductor adopts solely strand annealed copper wire, on said conductor, extrudes the crosslinked polyetylene insulated layer of XLPE and constitutes insulated wire cores; Two insulated cores are twisted into the pair twist group; What on said cable core, set gradually is: total screen that overlapping wrapped polyester belt, tincopper fuse wire braided armor, aluminum plastic composite belt longitudinal bag constitutes; And extrude vinyon formation outer jacket, in said tincopper fuse wire braided armor, be provided with drainage thread; Said conductor is that diameter is the bare copper wire of 1.14mm.
The design feature of the utility model transponder two core data cables also is:
The crosslinked polyetylene insulated layer of said XLPE extrudes the double hyer insulation layer of formation for the double-layer coextrusion method, and the thickness of double hyer insulation layer ectomesoderm is 0.05-0.07mm.
The count of said tincopper fuse wire braided armor is not less than 90%.
Said outer jacket is to be that material extrudes and forms with LLPE LLDPE or HDPE high density polyethylene (HDPE).
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model not only has the function of transmitting message data information and electric energy, and can resist that electromagnetic interference, insulation resistance are high, compressive resistance is high, under high frequency transmission signals undistorted, do not distort; It is the bare copper wire of 1.14mm that conductor adopts diameter, and its electricity function index satisfies the requirement of cable signal transmission parameter;
2, insulating barrier has adopted the crosslinked polyethylene of excellent electrical properties, superior in the utility model, and has adopted double-layer coextrusion technology, and insulation resistance is high;
3, the tincopper fuse wire braided armor count is not less than 90% in the utility model, and anti-electromagnetic interference performance is strong;
4, external sheath layer is that material extrudes and forms with LLDPE LLPE or high density polyethylene in the utility model, and waterproof, anticorrosion, environmental protection, accommodative ability of environment are strong, can satisfy the requirement of product adaptation complex environment.
Description of drawings
Fig. 1 is the utility model structural representation;
Label among the figure: 1 conductor, 2 insulating barriers, 3 pair twist groups, 4 polyester belts, 5 tincopper fuse wire braided armors, 6 drainage threads, 7 total screens, 8 external sheath layers.
Embodiment
Referring to Fig. 1, the version of transponder two core data cables is that conductor 1 adopts solely strand annealed copper wire in the present embodiment, on conductor 1, extrudes the crosslinked polyetylene insulated layer 2 of XLPE and constitutes insulated wire cores; Be twisted into pair twist group 3 with two insulated cores; What on cable core, set gradually is: total screen 7 that overlapping wrapped polyester belt 4, tincopper fuse wire braided armor 5, aluminum plastic composite belt longitudinal bag constitutes; And extrude vinyon formation outer jacket 8, in tincopper fuse wire braided armor 5, be provided with drainage thread 6.
In the practical implementation, conductor 1 is that diameter is the bare copper wire of 1.14mm; The crosslinked polyetylene insulated layer of XLPE 2 extrudes the double hyer insulation layer of formation for the double-layer coextrusion method, and the thickness of double hyer insulation layer ectomesoderm is 0.05-0.07mm; The count of tincopper fuse wire braided armor 5 is not less than 90%; Outer jacket 8 is to be that material extrudes and forms with LLPE LLDPE or HDPE high density polyethylene (HDPE).
