Abstract
The utility model discloses a high-permeability steel tape armored signal cable. The cable comprises a plurality of cable cores, each cable core conductor contains a fiber bundle reinforced core, the cable cores are wrapped by a polypropylene belting, the polypropylene belting is sequentially coated with an aluminum-plastic composite belt PE cushion layer, a high-permeability steel tape armored layer and an outer sheath, and two high-strength steel wires which are arranged along the longitudinal direction of the cable in parallel are arranged in the center of wall thickness of the outer sheath. In the aluminum-plastic composite belt PE cushion layer, an aluminum-plastic composite belt is 0.5mm thick and a PE cushion layer is 1.5mm thick. Compared with the prior art, the cable has a simpler overall structure and has two fewer production processes than an aluminum-sheathed cable, and the cost of the cable is greatly reduced; a high-permeability steel tape is used as the armored layer, which greatly improves the shielding performance of the cable; and the two high-strength steel wires are arranged in parallel in the center of wall thickness of the outer sheath to form a tensile member, which can help improve the strength of the cable and can protect the cable when the cable is under great tension.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of high magnetic conduction steel-tape armouring signal cable.
Background technology
At present, the integrated sheath railway signal cable of domestic production, when induced electromotive force is 35-200 V, desirable shielding factor is between 0.5～O.8, be not suitable for the electrified section that electromagnetic interference is stronger, but composite-sheathed cable has the characteristics that bending radius is little (15 times that minimum bending radius is cable size), can be used for the special location of laying.The desirable shielding factor of aluminium sheath railway signal cable is below 0.3, and bending radius must be greater than 20 times of cable size, the stronger special electrified section in some electromagnetic interference, although can meet the requirement of shielding properties, can not meet the requirement of laying environment.Simultaneously, the intensity of most of signal cable is poor, thereby has affected useful life.
The utility model content
The purpose of this utility model is to provide a kind of high magnetic conduction steel-tape armouring signal cable of new construction, its desirable shielding factor≤O.2, and also intensity is better.
For realizing this purpose, the technical solution of the utility model is: a kind of high magnetic conduction steel-tape armouring signal cable, comprise many group cable cores, described cable core conductor contains the fibre bundle strengthening core, described cable core is coated with the polypropylene band, described polypropylene band is provided with aluminium-plastic tape PE bed course, high magnetic conduction steel-tape armouring layer, oversheath outward successively, and described oversheath wall thickness middle position is provided with two high-tensile steel wires that are parallel to each other and arrange along the cable longitudinal direction.
As preferably, in described aluminium-plastic tape PE bed course, plastic-aluminum combined tape thickness is 0.5mm, and the PE cushion thickness is 1.5mm.
As preferably, described oversheath is termite-proof sheath.
As preferably, described cable core is comprised of the many stranded conductors that form of plain conductor and the insulating barrier that is coated on described conductor.
As preferably, described oversheath inboard also is provided with the webbed skeleton resistance to compression of circle braided steel wire layer.
Compared with prior art, the utility model has selected high magnetic conduction steel band as armour, and its relative permeability is 3000-4000, is 10-20 times of common low carbon steel band, greatly improves the shielding properties of cable.Overall structure is simpler, production process than aluminum-sheathed cable few twice (aluminium sheaths welding and bed course) again, greatly shortened production cycle and production cost, reduced 10%-20% than the material cost of aluminum-sheathed cable under equal performance.In addition, at the central high-tensile steel wires that arrange by two parallel placements of the wall thickness of sheath, form tension member, contribute to promote cable intensity, can play a protective role to cable when cable bears larger pulling force.Simultaneously, be provided with the webbed skeleton resistance to compression of circle braided steel wire layer in described inner sheath inboard, further promoted the tensile and compressive property of cable.The of the present utility model research and development successfully, further expanded the range of application of composite-sheathed cable.
The accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Wherein: 1. cable core, 2. polypropylene band, 3. aluminium-plastic tape PE bed course, 4. high magnetic conduction steel-tape armouring layer, 5. oversheath.
embodiment
The utility model is further illustrated with reference to the accompanying drawings in conjunction with the embodiments.
As shown in Figure 1, a kind of high magnetic conduction steel-tape armouring signal cable, comprise three groups of cable cores 1, and every group of cable core is comprised of the many stranded conductors that form of plain conductor and the insulating barrier that is coated on described conductor, and the cable core conductor contains the fibre bundle strengthening core.Cable core is coated with polypropylene band 2, its integrated sheath adopts the aluminum plastic composite belt longitudinal bag cable core that thickness is 0.5mm, and welded with hot air welding gun, the PE bed course that to extrude a layer thickness be 1.5mm simultaneously, and left-hand is asked the structure of the wrapped two floor height magnetic conduction steel bands 4 of gap as armour.Described oversheath 5 is termite-proof sheath; Described oversheath inboard also is provided with the webbed skeleton resistance to compression of circle braided steel wire layer.
The improvement that the utility model carries out mainly for the signal cable structure, the foregoing is only the utility model preferred embodiment, non-so limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as doing by the utility model specification and graphic content, all should be contained in the scope of the claims of the present utility model.
