Abstract
The invention provides a railway digital signal cable comprising a cable core and a sheath. The sheath is provided with a non-moisture absorption insulating tape wrapping layer, a metal protection cover, a polyethylene bonding protection layer, an armor layer welded with steel strips and an outer protection cover which are sequentially arranged from inside to outside. The armor layer seamlessly covers the polyethylene bonding protection layer. According to the arrangement, the armor layer tube shaped is formed by longitudinally welding the steel strips without seams, shielding effect is good, fewer steel strips are required, production efficiency is high, and protection cost is low; the armor layer is provided with an embossing structure, leading to high structural strength and less deformation proneness, and the cable is high in extension strength and bending performance; the non-moisture absorption insulating tape wrapping layer, the aluminum or comprehensive protection cover, the polyethylene bonding protection layer and the outer protection cover are provided outside the cable core, so that the cable is excellent in functions such as shielding, temperature resistance, moisture resistance, extension resistance and animal bites prevention and meets the requirement of the high speed railway.
Description
Technical field
The invention belongs to field of cable technology, especially relate to a kind of railway digital signal cable.
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.In railway digital signal cable production process of the prior art; steel band the coated mode mainly adopting wrapped or vertical bag; adopt the railway digital signal cable that this two kinds of modes are produced; the quality problems causing steel aluminium to mix mutually when often can there is bottom pour ladle, bale breaking or invar band defectiveness; cable is once generation bottom pour ladle, bale breaking or steel aluminium mix mutually; the shielding properties of cable can be had a strong impact on, caused great potential safety hazard to railway transportation.
Summary of the invention
In view of this, the present invention is intended to propose a kind of railway digital signal cable, and shield effectiveness is good, and steel band consumption is little, and production efficiency is high, low cost of manufacture.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of railway digital signal cable, comprises cable core and is coated on the sheath outside cable core; Described sheath set gradually from the inside to the outside non-hygroscopic insulating tape lapping layer, metallic sheath, polyethylene bonding sheath, steel band welding armour and oversheath; Integral coating that described armour is seamless is outside polyethylene bonding sheath.
Further, described cable core forms by several wire group is stranded.
Further, described steel band is high magnetic conduction galvanized steel strip.
Further, described armour is the tubular structure of steel band longitudinal measure, which is provided with embossing.
Further, described metallic sheath is aluminium sheath or composite sheath.
Further, described oversheath is pe sheath.
Relative to prior art, a kind of railway digital signal cable of the present invention has following advantage:
1) become the armour of tubulose with steel band longitudinal measure, seamless, shield effectiveness is good, and steel band consumption is little, and production efficiency is high, low cost of manufacture.
2) armour of steel band welding has boss structure, and structural strength is high, not yielding, and cable has higher tensile strength and bending property.
3) by arranging non-hygroscopic insulating tape lapping layer, aluminium sheath or composite sheath, polyethylene bonding sheath and oversheath outside cable core, make the functions such as cable has superior shielding, heatproof, protection against the tide, resistance to compression, anti-animal tooth are stung, meet the requirement of high-speed railway to cable completely.
Accompanying drawing explanation
The accompanying drawing forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is structural representation of the present invention.
Description of reference numerals:
1-wire group, 2-cable core, 3-non-hygroscopic insulating tape lapping layer, 4-metallic sheath, 5-polyethylene bonding sheath, 6-armour, 7-oversheath.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
A kind of railway digital signal cable, as shown in Figure 1, the sheath comprising cable core 2 and be coated on outside cable core 2; Described sheath set gradually from the inside to the outside non-hygroscopic insulating tape lapping layer 3, metallic sheath 4, polyethylene bonding sheath 5, steel band welding armour 6 and oversheath 7; The seamless integral coating of described armour 6 is outside polyethylene bonding sheath 5.
It should be noted that, oversheath 7 is for extruding the polyethylene layer at the outside one deck of armour 6.
Wherein, described cable core 2 forms by several wire group 1 is stranded.
Wherein, described steel band is high magnetic conduction galvanized steel strip, and have good anticorrosion and shielding properties, structural strength is high, and its inner cable core can be protected to damage from external impacts.
Wherein, described armour 6 is the tubular structure of steel band longitudinal measure, which is provided with embossing, firm in structure, not yielding.
Wherein, described metallic sheath 4 is aluminium sheath or composite sheath, selects the sheath of respective material according to different applying working conditions.
Wherein, described oversheath 7 is pe sheath, and its electrical insulating property is good, and chemical stability is strong, and has very low gas permeability and less water absorption, and proportion is little, and non-toxic, meanwhile, plasticity is good, is easy to machine-shaping.
During making, first make cable core 2 by stranded together for several wire group 1, then at cable core 2 outer cladding non-hygroscopic insulating tape lapping layer 3, metallic sheath 4, polyethylene bonding sheath 5, embossing bonding machine is adopted to utilize argon arc welding continuous welding process, what steel band longitudinal measure is become pipe integral seamless gap is coated on outside polyethylene bonding sheath 5, carry out embossing afterwards, finally outside the armour 6 of steel band welding embossing, extrude layer of polyethylene oversheath 7.
Digital signal cable provided by the invention has good shielding, heatproof, protection against the tide, resistance to compression, anti-animal tooth sting function, and the security reliability of cable is high.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
