Abstract
The utility model relates to the technical field of cable industry, in particular to an aluminum sheath extruded type railway signal cable comprising a cable core. The cable core is formed by stranding a plurality of guide wire groups, and the guide wire groups are formed by stranding two or four guide wires; a cable core coating tape layer, a heat insulating layer, an internal padding layer, a double-steel-tape armored layer and an external sheath coats the cable core sequentially from interior to exterior; an aluminum sheath shielding layer is arranged between the heat insulating layer and the internal padding layer. When the cable is used, owing to the reasonable design of the cable shielding layer in an entirely coated manner without gaps, electromagnetic leakage is avoided, external interference is avoided during signal transmission, and train operation safety can be guaranteed effectively. In addition, the coating aluminum sheath shielding layer formed by extruding is solid and not prone to deformation, and the cable has high tensile strength and bending properties.
Description
Technical field
The utility model relates to cable industry technical field, and particularly a kind of aluminium sheath extrudes the railway signal cable of type.
Background technology
In prior art, for the mode of production of its aluminium sheath of aluminium sheath signal cable of railway signal system, being mainly to adopt argon arc welding continuous welding process, is that a kind of argon gas that utilizes is as a kind of electrogas arc welding method of protective gas.In Practical manufacturing process, due to a variety of causes such as aluminium plate oxidation, corrosion or forming frock die debugging be bad, often occur aluminium sheath weld seam partially weldering, solder skip, there are the various serious quality problems such as trachoma, non-conductive gap due to the discontinuous of shield and the formation of shield different piece junction, capital produces electromagnetic leakage, have a strong impact on the shielding properties of cable, to railway transportation, caused great potential safety hazard.Therefore, existing railway signal cable structure is carried out to further technological innovation and become what the trend requires.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides aluminium sheath a kind of simple in structure, reasonable in design, easy to use to extrude the railway signal cable of type.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of aluminium sheath described in the utility model extrudes the railway signal cable of type, comprise cable core, described cable core is by stranded the forming of several wire groups, wire group is formed by two or four wire strandings, cable core is outer by interior cable core belting layer, thermal insulation layer, inner cushion layer, double-tape armor layer and the oversheath of being coated with successively outward, is provided with aluminium sheath screen between described thermal insulation layer and inner cushion layer.
Above-mentioned a kind of aluminium cover extrudes the railway signal cable of type, and the cable core described in it at least comprises that a wire group forms.
Above-mentioned a kind of aluminium cover extrudes the railway signal cable of type, and the wire described in it comprises conductor and is arranged on the insulating barrier composition outside conductor.
Above-mentioned a kind of aluminium cover extrudes the railway signal cable of type, and the aluminium sheath screen described in it is the coated aluminium sheath screen of extrusion molding.
Adopt after said structure, the utility model beneficial effect is: when using the utility model, by the appropriate design to cable shield, screen integral coating, does not have gap, can not produce electromagnetic leakage, shield effectiveness is good, in signals transmission, be not subject to other external interference, can effectively guarantee train operating safety.In addition, the coated aluminium sheath screen of extrusion molding is firm, not yielding, and cable has higher tensile strength and bending property.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of aluminium sheath described in the utility model extrudes the railway signal cable of type, comprise cable core 3, described cable core 3 is by stranded the forming of several wire groups 2, wire group 2 is by two or four stranded forming of wire 1, wire 1 comprises conductor and is arranged on the insulating barrier outside conductor, cable core 3 is outer by interior cable core belting layer 4, thermal insulation layer 5, inner cushion layer 7, double-tape armor layer 8 and the oversheath 9 of being coated with successively outward, is provided with the coated aluminium sheath screen 6 of extrusion molding between described thermal insulation layer 5 and inner cushion layer 7.Said structure forms main body of the present utility model.
This aluminium sheath screen 6 utilizes extruder to adopt to extrude the mode of production of type, thereby screen do not have weld seam, and screen there will not be solder skip, quality problems such as weldering and weld seam trachoma partially, and shield effectiveness is very good.
When using the utility model, by the appropriate design to cable shield, screen integral coating, does not have gap, can not produce electromagnetic leakage, and shield effectiveness is good, in signals transmission, is not subject to other external interference, can effectively guarantee train operating safety.In addition, the coated aluminium sheath screen of extrusion molding is firm, not yielding, and cable has higher tensile strength and bending property.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
