Abstract
The utility model discloses a quadded data transmission cable of a transponder, which is characterized in that a conductor of the cable adopts a single-strand soft copper wire; an insulated wire core formed by extruding XLPE (crosslinked polyethylene) insulating layer is formed on the conductor; four insulated wire cores are twisted to be a quad star shape set to form a cable core; a polyester strap wrapped in an overlapping manner, a tinned copper wire braid, a general shielding layer formed by a composite aluminium-plastic tape, and an external protective layer formed by the extruded polyethylene plastic are sequentially arranged on the cable core; and a current guiding wire is arranged in the tinned copper wire braid. The quadded data transmission cable has the function of transmitting message, data information and electric energy and has the advantages of electromagnetic interference resistance, high insulation resistance and high voltage withstanding strength, the signals transmitted by the cable under high frequency do not distort or deform 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 four-core data cable, 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 four-core data cable 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 four-core data cable is 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 technical solution problem adopts following technical scheme:
The design feature of the utility model transponder four-core data cable 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; Four insulated cores are twisted into the star quad stranding group and form cable core; 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 crosslinked polyetylene insulated layer of said XLPE extrudes the double hyer insulation layer of formation for the double-layer coextrusion method.
The design feature of the utility model transponder four-core data cable also is:
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;
2, conductor employing diameter is the bare copper wire of 1.14mm in the utility model, and its electricity function index satisfies the requirement of cable signal transmission parameter;
3, 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;
4, the tincopper fuse wire braided armor count is not less than 90% in the utility model, and anti-electromagnetic interference performance is strong;
5, 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 star quad stranding 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 four-core data cable 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 star quad stranding group 3 with four insulated cores and form cable core; 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).
