Abstract
The utility model provides a railway signal cable. The cladding has the cable core in signal cable's the stainless steel inoxidizing coating, and the outside cladding of stainless steel inoxidizing coating has fire -retardant oversheath, the at least a set of star quad of cladding or pair twist group or insulated conductors in the cable core. The cable core cladding is by conductor and the insulated conductors that forms at the outside wrap -around insulating layer of conductor, is equipped with the outward flange in close contact with of many nylon wires, nylon wire and insulating layer at the center of cable core. The stainless steel inoxidizing coating prick the nonrust steel pipe of line for the annealing type. Can divide formula star quad tied in a bundle in the cable core of this cable for rotatory extruding simultaneously, for one whole, difficult by extrusion deformation for the cable electric property is more superior, has guaranteed railway transmission signal's stability, safety, and owing to be the quad of extruding simultaneously, saved the process of one stranded conductor, has reduced manufacturing cost.
Description
Technical field
The utility model relates to electric wire field, is related specifically to a kind of railway signal cable.
Background technology
In China railways industry, railway signal system is generally used, and signal cable is applicable to rated voltage and exchanges fixedly laying of 500V or direct current 1000V and following transmission railway signal, audio signal or some automatics purposes.
Existing railway signal cable comprises cable core, the restrictive coating be coated on outside cable core.There is quad in usual cable core, sometimes also comprise pair twist group or single line; Because in cable core, quad, pair twist group are all form by single line is stranded, structure is very unstable, and the general tied silk band that adopts is fixed, and affects, is easily extruded distortion, thus affect the quality safety of Signal transmissions in the production and site operation of cable by external force.And restrictive coating comprises alibate, sheath, steel-tape armouring layer and outer jacket successively; Because restrictive coating is too much, cause production process too much, production cost strengthens, and the wasting of resources is also just same to be increased.
Summary of the invention
The purpose of this utility model is to provide a kind of railway signal cable adopting annealing type to prick line stainless steel tube and nylon wire, its objective is the effect making cable not only have shielding external signal, when cable can be made to be squeezed, not yielding simultaneously.
For achieving the above object, the technical solution of the utility model is:
A kind of railway signal cable, comprise cable core, stainless steel protective cover, fire-retardant oversheath, conductor, insulating barrier and nylon wire, cable core is coated with in the stainless steel protective cover of described signal cable, the outside of stainless steel protective cover is coated with fire-retardant oversheath, coated at least one group of star quad or twisted pair wire group or insulated single wire in cable core.
Described cable core is coated with by conductor and the insulated single wire that forms at the outside coated insulating barrier of conductor, at the center of cable core, many nylon wires is housed, the outward flange close contact of nylon wire and insulating barrier.
The rotary extrusion while that the insulating barrier of described quad being, and insulating barrier is solid construction.
Described star quad forms by four insulated single wires are stranded.
Described stainless steel protective cover is that line stainless steel tube pricked by annealing type.
Good effect of the present utility model is:
Cluster type star quad can be divided for rotary extrusion simultaneously in the cable core of 1, this cable, be an entirety, more a lot of than general cable conductor Stability Analysis of Structures, not easily be extruded distortion, make cable electrical performance more superior, ensure that stable, the safety of railway signal transmission, and owing to being the quad extruded simultaneously, save the operation of one twisted wire, reduce production cost;
2, oversheath adopt a kind of annealing type to prick line is stainless steel welded forms, make cable not only have the effect of shielding external signal, and can cable core be protected, also can save material simultaneously, reduce costs;
3, the solid construction that adopts of the insulation of this cable, makes the anti-compression properties of cable more superior, solves railway cable and lay middle cable insulation and easily damage by pressure, and cause the shortcoming of short circuit between the lines;
4, the outermost layer employing LSOH anti-flaming plastic sheath of this cable can be effectively fire-retardant, environmental protection.
Accompanying drawing explanation
Fig. 1, railway signal cable cross section structure schematic diagram;
Fig. 2, star quad cable core cross-section structural representation.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with attached Fig. 1 and 2.
See Fig. 1 and Fig. 2; conductor 4 coated in cluster type star quad cable core 1 can be divided for signal transmission; the outside coated insulating barrier 5 of conductor 4 plays insulating effect for the protection of conductor 3 simultaneously; when the nylon wire 6 that cable core 1 center fills is for laying wiring or inspection time; separation can divide cluster type star quad; the stainless steel protective cover 2 being enclosed within star quad cable core 1 outside, for the effect of the shielding to cable core 1, protection against the tide, anticorrosion and protection cable core 1, is coated on the fire-retardant oversheath 3 of stainless steel protective cover 2 outside for the fire-retardant of signal cable and waterproof.
