Abstract
The utility model discloses a two-core data cable used for a rail haulage motor. The two-core data cable is characterized in that conductors adopt a one-strand soft copper wire, and PE (polyethylene) insulation layers are extruded on the conductors to form insulated wire cores; two insulated wire cores are twisted into a pair of twisted group so as to form a cable core; the cable core is successively provided with a polyester belt layer formed by overlapped coating, a shielding layer formed by embossing and longitudinal coating of a copper belt, a liner layer formed by extrusion of polyethylene plastic, a longitudinal coated or extruded aluminum cover layer, an isolating layer formed by extrusion of polyethylene plastic, an armor layer formed by coating of a double-layer steel belt at interval and an outer sheath layer formed by extrusion of plastic; and a drainage wire is arranged between the polyester belt layer and the shielding layer. The two-core data cable disclosed by the utility model is used for the transmission of analog information, numerical information and electrical energy, has the advantages of electromagnetic interference resistance, good insulating property, high compressive strength, and undistorted high-frequency transmission signal.
Description
Technical field
The utility model relates to a kind of signal and data cable, relates in particular to a kind of rail locomotive with two core data cables, belongs to technical field of electric wires and cables.
Background technology
High-speed rail transportation is the Future Development important directions.Its electrified level requires also increasingly high.Transponder and LEU LEU are one of important components and parts of railway control, and the connecting line between it will have transmitting message data information and electric energy function.According to the requirement of the environment for use of railway engineering, electric properties such as the insulation of its cable, characteristic impedance, attenuation constant, shielding factor are had relatively high expectations, and it is high that proof voltage intensity is also wanted, can be under high-transmission frequency 1.8MHz transmission signals undistorted, do not distort.
Because it has special electric, mechanical and anti-environmental requirement, its structure and material is selected for use also has certain particularity, adopts existing cable of the same type can't satisfy the whole service requirement of engineering.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point; Provide a kind of rail locomotive with two core data cables; Function with transmitting message data information and electric energy; And have anti-electromagnetic interference, insulation property are good, compressive resistance is high, transmission signals is undistorted under high frequency, advantage such as do not distort.
The utility model technical solution problem adopts following technical scheme:
The utility model rail locomotive is that conductor adopts solely strand annealed copper wire with the design feature of two core data cables, on said conductor, extrudes the PE polyethylene layer and constitutes insulated wire cores; Two insulated cores are twisted into the pair twist group and form cable core, on said cable core, set gradually the external sheath layer that overlapping wrapped polyester belt, copper strips embossing is indulged the armour of the screen that wraps formation, the inner covering that extrudes vinyon formation, the vertical alibate that wraps or extrude, the separator that extrudes vinyon formation, the wrapped formation of clad steel band gap, extruded plastics formation; Between said polyester belt and screen, drainage thread is set.
The utility model rail locomotive also is with the design feature of two core data cables:
It is the bare copper wire of 1.14mm or 1.53mm that said conductor adopts diameter.
Said PE polyethylene layer is to adopt the double-layer coextrusion method to extrude the double hyer insulation that forms, and the thickness of said double hyer insulation layer ectomesoderm is 0.05-0.07mm.
The pair twist pitch of said pair twist group is 80-110mm.
Said inner covering, separator and external sheath layer are to adopt LLDPE LLPE or high density polyethylene to extrude to form.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model can be used for the transmission of analog information, digital information and electric energy, has anti-electromagnetic interference, insulation property are good, compressive resistance is high, the distortionless advantage of high-frequency transmission signal.
2, conductor adopts the bare copper wire diameter for for 1.14mm or 1.53mm conductor in the utility model, has guaranteed that electricity function index satisfies the requirement of cable signal transmission parameter;
3, the pair twist pitch of the utility model pair twist group is set to 80-110mm, reduced line between cross-talk and electromagnetic coupled, improved the cable quality;
4, the utility model inner covering, separator and external sheath layer employing LLDPE LLPE or high density polyethylene extrude and form; Make it have waterproof, anticorrosion, environmental protection, characteristic that anti-environment capacity is 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 screens, 6 drainage threads, 7 inner coverings, 8 alibates, 9 separators, 10 armours, 11 external sheath layers.
Embodiment
The utility model rail locomotive with the version of two core data cables is:
Conductor adopts solely strand annealed copper wire, on conductor, extrudes the PE polyethylene layer and constitutes insulated wire cores; Two insulated cores are twisted into the pair twist group and form cable core, on cable core, set gradually the external sheath layer that overlapping wrapped polyester belt, copper strips embossing is indulged the armour of the screen that wraps formation, the inner covering that extrudes vinyon formation, the vertical alibate that wraps or extrude, the separator that extrudes vinyon formation, the wrapped formation of clad steel band gap, extruded plastics formation; Between polyester belt and screen, drainage thread is set.
In the practical implementation, it is the bare copper wire of 1.14mm or 1.53mm that conductor adopts diameter; The PE polyethylene layer is to adopt the double-layer coextrusion method to extrude the double hyer insulation that forms, and the thickness of double hyer insulation layer ectomesoderm is 0.05-0.07mm; The pair twist pitch of pair twist group is 80-110mm; Inner covering, separator and external sheath layer are to adopt LLDPE LLPE or high density polyethylene to extrude to form.
