Background technology
Along with the high speed development of railway traffic cause, traffic safety has become the problem that the whole society pays close attention to.The speed goes of railway traffic is fast, and traffic administration is more and more concentrated, and data-signal transmission means presents variation.For ensureing that railway signal transmission system safely and steadily runs, day by day vigorous to the railway digital signal cable demand of high-performance, high strength.Railway digital signal cable of the prior art, due to design existing defects, the environmental-protecting performance of cable shield and resistance to chemical corrosion, bending property, mechanical strength, shield effectiveness etc. all can not meet the growth requirement of current high-speed railway, certain pollution is all existed to the earth, air, great threat is caused to the security reliability of train.
Utility model content
In view of this, the utility model is intended to propose a kind of railway digital signal cable, and structure is simple, reasonable in design, has good mechanical strength and bending property, and shield effectiveness is good.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of railway digital signal cable, comprises by the stranded cable core of at least two wire groups; Each described wire group is formed by two or four wire strandings; Cable core belting layer, thermal insulation layer, alloy sleeve screen, inner cushion layer, armour and oversheath is coated with from the inside to the outside successively outward at described cable core; Described alloy sleeve screen integral seamless gap is coated between thermal insulation layer and inner cushion layer.
Further, described wire comprises the insulating barrier outside conductor and conductor.
Further, described armour is double-tape armor layer.
Further, described alloy sleeve screen is ormolu layer.
Further, described alloy sleeve screen outer surface has passivation layer.
Relative to prior art, a kind of railway digital signal cable described in the utility model has following advantage:
1) construction of cable is simple, reasonable in design, and environmental-protecting performance is superior, good bending property, mechanical strength are high, and shield effectiveness is good, effectively can ensure train operating safety.
2) alloy sleeve screen outer surface has passivation layer, and the long-term direct-burried of cable is when underground, and cable shield can not can not be oxidized by burn into, and environmental-protecting performance is superior.
3) armour is double-tape armor layer, and structural strength is high, can be good at protecting its inside and does not damage by external impacts, and useful life improves, and reduces fault and occurs.
4) alloy sleeve screen integral seamless gap is coated between thermal insulation layer and inner cushion layer, and shield effectiveness is good, anti-oxidant, anticorrosion ability good.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-wire; 2-wire group; 3-cable core; 4-cable core belting layer; 5-thermal insulation layer; 6-alloy sleeve screen; 7-inner cushion layer; 8-armour; 9-oversheath.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of railway digital signal cable, as shown in Figure 1, comprises by the stranded cable core 3 of at least two wire groups 2; Each described wire group 2 is by two or four wires 1 are stranded forms; Cable core belting layer 4, thermal insulation layer 5, alloy sleeve screen 6, inner cushion layer 7, armour 8 and oversheath 9 is coated with from the inside to the outside successively outside described cable core 3; Described alloy sleeve screen 6 integral seamless gap is coated between thermal insulation layer 6 and inner cushion layer 7.
Need to illustrate time, alloy sleeve screen 6 integral seamless gap is coated between thermal insulation layer 5 and inner cushion layer 7, and shield effectiveness is good, anti-oxidant, anticorrosion ability good.
Alloy sleeve screen 6 can adopt the production technology extruding or weld to be coated on outside thermal insulation layer 5.For improving environmental protection and the decay resistance of cable, after alloy sleeve screen 6 has been produced, pickling and Passivation Treatment need be carried out, such design, the long-term direct-burried of cable is when underground, and cable shield can not can not be oxidized by burn into, environmental-protecting performance is superior, resistance to chemical corrosion is strong, good bending property, mechanical strength are high, shield effectiveness is good, effectively can ensure train operating safety, extends the useful life of cable.
In addition, thermal insulation layer 6 and inner cushion layer 7 can be the material that polyethylene layer or employing have fire resistance.
Wherein, described wire 1 comprises the insulating barrier outside conductor and conductor.Insulation effect is good, and fail safe is high, conductor propagation signal stabilization.
Wherein, described armour 8 is double-tape armor layer.Structural strength is high, can be good at protecting its inside and does not damage by external impacts, and useful life improves, and reduces fault and occurs.
Wherein, described alloy sleeve screen 6 is ormolu layer, and structural strength is high, advantages of good shielding performance.
Wherein, described alloy sleeve screen 6 outer surface has passivation layer.Like this, the long-term direct-burried of cable is when underground, and cable shield can not can not be oxidized by burn into, and environmental-protecting performance is superior.
The construction of cable that the utility model provides is simple, reasonable in design, and environmental-protecting performance is superior, good bending property, mechanical strength are high, and shield effectiveness is good, effectively can ensure train operating safety.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
