Each single insulating wire is composed of a cooper conductor, an inner insulating layer wrapping the periphery of the copper conductor, a copper wire weaving shielding layer wrapping the inner insulating layer, and an outer insulating layer wrapping the periphery of the copper wire weaving shielding layer.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of signal cable of new structure.
Background technology
In prior art, the mode of cable shield mainly contains three kinds, and a kind of is to be undertaken individually shielded by all quads in cable core; A kind of is vertical bag or wrapped aluminium-plastic tape outside cable core; Another kind is welded tube aluminium sheath outside cable core.Nowadays, along with the again and again speed-raising of Line for Passenger Transportation and existing railway, more strict to the cross-talk of cable and the performance requirement such as anti-interference.These three kinds of shielding modes of the prior art, though can reach certain anti-cross-talk and antijamming capability, cable core center line pair and line pair, the cross-talk problem between single line and single line still exists constantly.
The serious place in some interference of electromagnetic field, existing shielding mode can not mask all interference sources fully, and in such situation, the coefficient of safety of train will be subject to great threat.Therefore, a kind of anti-cross-talk and antijamming capability is strong, shielding properties is superior signal cable will become what the trend requires.
Summary of the invention
Purpose of the present invention is exactly the deficiency in order to overcome existing signal cable technology and a kind of anti-cross-talk and antijamming capability is strong, shielding properties is superior signal cable are provided.
For achieving the above object, the present invention solves the scheme that its technical problem takes and is:
The sort signal cable, comprise cable core and be coated on the outer oversheath of cable core, described cable core is outside equipped with the non-hygroscopic insulating barrier, described non-hygroscopic insulating barrier is the vertical integrated sheath that is surrounded by outward, described integrated sheath is outside equipped with the welded tube aluminium sheath, described welded tube aluminium sheath is outside equipped with the polyethylene bonding sheath, between described polyethylene bonding sheath and oversheath, is provided with the double-tape armor layer.
Further, be provided with severally to line group or quad in described cable core, described the line group formed by the insulated single wire of two different colours is stranded, described quad forms by the insulated single wire of four different colours is stranded.Described insulated single wire is comprised of copper conductor, the inner insulating layer that is coated on the copper conductor periphery, the external insulation layer that is coated on the outer copper wire woven screen of inner insulating layer and is coated on copper wire woven screen periphery.
Further, described copper wire woven screen braiding tightness is not less than 85%, and the braided wires diameter is not less than 0.1 mm.
Further, described inner insulating layer and external insulation layer are polyolefin insulation layer.
Further, by soft copper band embossing layer and extrusion molding, pe sheath outside the vertical covering of embossing forms described integrated sheath.
Further, the vertical cladding thickness of described embossing is not less than 0.09 mm.
Compared with prior art, usefulness of the present invention is: the sort signal cable adopts the copper wire woven screen to carry out individually shielded to insulated single wire, solved in the prior art can only to the line group screen cover and the line group center line that causes pair and line to the cross-talk problem between, single line and single line, and adopt the screen of copper wire woven shielding as insulated single wire, the light softness of cable, shielding properties is strong; Select polyolefine material to be used as the insulated single wire insulating barrier, make cable there is excellent ageing-resistant performance and mechanical strength.In addition, select polyolefine material to be used as the insulated single wire insulating barrier, can make insulating barrier and conductor be bonded together better, guarantee electric stability and the moisture resistance of insulation system.
the accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is signal cable structural representation of the present invention.
In figure: 1, cable core; 2, insulated single wire; 3, copper conductor; 4, inner insulating layer; 5, copper wire woven screen; 6, external insulation layer; 7, non-hygroscopic insulating barrier; 8, integrated sheath; 9, aluminium sheath; 10, polyethylene bonding sheath; 11, double-tape armor layer; 12, oversheath.
Embodiment
Below in conjunction with the drawings and the specific embodiments, describe the present invention:
A kind of signal cable shown in Fig. 1, comprise cable core 1 and be coated on the outer oversheath 12 of cable core 1, described cable core 1 is outside equipped with non-hygroscopic insulating barrier 7, the outer vertical integrated sheath 8 that is surrounded by of described non-hygroscopic insulating barrier 7, described integrated sheath 8 is outside equipped with welded tube aluminium sheath 9, described welded tube aluminium sheath 9 is outside equipped with polyethylene bonding sheath 10, between described polyethylene bonding sheath 10 and oversheath 12, is provided with double-tape armor layer 11.
In described cable core 1, be provided with several to line group or quad, described to the line group stranded the forming of insulated single wire 2 by two different colours, described quad is by stranded the forming of insulated single wire 2 of four different colours.Described insulated single wire 2 is comprised of copper conductor 3, the inner insulating layer 4 that is coated on copper conductor 3 peripheries, the external insulation layer 6 that is coated on the outer copper wire woven screen 5 of inner insulating layer 4 and is coated on copper wire woven screen 5 peripheries.
Described copper wire woven screen 5 braiding tightnesss are not less than 85%, and the braided wires diameter is not less than 0.1 mm.
Described inner insulating layer 4 and external insulation layer 6 are polyolefin insulation layer.
By soft copper band embossing layer and extrusion molding, pe sheath outside the vertical covering of embossing forms described integrated sheath 8.
The vertical cladding thickness of described embossing is not less than 0.09 mm.
The sort signal cable adopts the copper wire woven screen to carry out individually shielded to insulated single wire, solved in the prior art can only to the line group screen cover and the line group center line that causes pair and line to the cross-talk problem between, single line and single line, and adopt the screen of copper wire woven shielding as insulated single wire, the light softness of cable, shielding properties is strong; Select polyolefine material to be used as the insulated single wire insulating barrier, make cable there is excellent ageing-resistant performance and mechanical strength.In addition, select polyolefine material to be used as the insulated single wire insulating barrier, can make insulating barrier and conductor be bonded together better, guarantee electric stability and the moisture resistance of insulation system;
