Description
Technical field
The present invention relates to a kind of signal cable, particularly a kind of copper strips welding embossing internal screening railway digital signal cable.
Background technology
The both direction of current railway locomotive development, the one, passenger traffic adopts high speed motor car, and the 2nd, shipping adopts the heavy traction of the marshalling of growing up.High speed motor car and heavy traction are had higher requirement to fail safe and comfortableness, in existing internal screening railway digital signal cable production process, the coated of shielding is mainly the mode that adopts wrapped or vertical bag, adopt this two kinds of internal screening railway digital signal cables that mode is produced, often can there are the quality problems that copper strips bottom pour ladle or copper strips seam crossing split, due to the non-conductive gap of 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, cause great potential safety hazard to railway transportation.
Summary of the invention
The present invention seeks to the deficiency in order to overcome existing internal screening railway digital signal cable technology and a kind of copper strips welding embossing internal screening railway digital signal cable is provided.
The present invention solves the scheme that its technical problem takes:
This copper strips welding embossing internal screening railway digital signal cable, comprise cable core, be coated on the sheath outside cable core, described cable core comprises at least one shielding quad, described shielding quad comprises the insulated single wire of four mutually stranded settings of different colours, each insulated single wire is made up of copper conductor and the insulating barrier that is coated on copper conductor periphery, described insulated single wire periphery is surrounded with bundle yarn, described bundle yarn is disposed with inner side non-hygroscopic insulating barrier outward, copper strips welding embossing screen and outside non-hygroscopic insulating barrier, described sheath comprises PET band lapping layer from the inside to the outside successively, aluminium sheath, polyethylene bonding sheath, the wrapped armour in galvanized steel strip gap and oversheath.
Preferably, between described inner side non-hygroscopic insulating barrier and copper strips welding embossing screen, be provided with earial drainage wire.
Preferably, described insulating barrier is three-layer co-extruded skin-bubble-Pi physical blowing structure.
Compared with prior art, usefulness of the present invention is: this copper strips welding embossing internal screening railway digital signal cable adopts copper strips welding embossing screen, and screen does not have gap, can not produce electromagnetic leakage, and shield effectiveness is good.In addition, copper strips welding embossing screen is firm, not yielding, and cable has higher tensile strength and bending property; Simultaneously, by PET band lapping layer, aluminium sheath or composite sheath, polyethylene bonding sheath, the wrapped armour in galvanized steel strip gap, outer protective polyethylene cover are set outward at cable core, make cable there is superior shielding, heatproof, protection against the tide, resistance to compression, anti-animal tooth and the function such as sting, meet the requirement to cable of high-speed railway and heavy traction completely.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is copper strips welding embossing internal screening railway digital signal cable structural representation of the present invention.
In figure: 1, shielding quad; 2, insulated single wire; 3, copper conductor; 4, insulating barrier; 5, prick yarn; 6, inner side non-hygroscopic insulating barrier; 7, earial drainage wire; 8, copper strips welding embossing screen; 9, outside non-hygroscopic insulating barrier; 10, PET band lapping layer; 11, aluminium sheath; 12, bonding sheath; 13, the wrapped armour in galvanized steel strip gap; 14, oversheath.
Embodiment
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of copper strips welding embossing internal screening railway digital signal cable shown in Fig. 1, comprise cable core, be coated on the sheath outside cable core, described cable core comprises at least one shielding quad 1, described shielding quad 1 comprises the insulated single wire 2 of four mutually stranded settings of different colours, each insulated single wire 2 is made up of copper conductor 3 and the insulating barrier 4 that is coated on copper conductor 3 peripheries, described insulated single wire 2 peripheries are surrounded with pricks yarn 5, the outer inner side non-hygroscopic insulating barrier 6 that is disposed with of described bundle yarn 5, copper strips welding embossing screen 8 and outside non-hygroscopic insulating barrier 9, described sheath comprises PET band lapping layer 10 from the inside to the outside successively, aluminium sheath 11, polyethylene bonding sheath 12, the wrapped armour 13 in galvanized steel strip gap and oversheath 14.
Between described inner side non-hygroscopic insulating barrier and copper strips welding embossing screen, be provided with earial drainage wire.
Described insulating barrier is three-layer co-extruded skin-bubble-Pi physical blowing structure.
Described bonding sheath is polyethylene bonding sheath.
Described oversheath is outer protective polyethylene cover.
When making, first the insulated single wire of four different colours is twisted into quad, and the non-moist insulating barrier 6 of wrapped bundle yarn 5 and coated inner side outside, then earial drainage wire 7 is arranged on inner side non-hygroscopic insulating barrier 6, adopt embossing bonding machine to utilize argon arc welding continuous welding process, copper strips is longitudinally welded on the insulated single wire 2 of four mutually stranded settings of different colours that pipe is coated with inner side non-hygroscopic insulating barrier 6 described in being coated on and carries out embossing again, after embossing, outside copper strips welding embossing screen 8, be coated again the non-moist insulating barrier 9 in outside, again by all line groups together stranded cable core of making, then be coated successively PET band lapping layer 10 outward at cable core, aluminium sheath 11, bonding sheath 12, the wrapped armour 13 in galvanized steel strip gap, oversheath 14, make copper strips welding embossing internal screening railway digital signal cable of the present invention.Described aluminium sheath 11 can also be composite sheath.
This copper strips welding embossing internal screening railway digital signal cable adopts copper strips welding embossing screen, and screen does not have gap, can not produce electromagnetic leakage, and shield effectiveness is good.In addition, copper strips welding embossing screen is firm, not yielding, and cable has higher tensile strength and bending property; Simultaneously, by PET band lapping layer, aluminium sheath or composite sheath, polyethylene bonding sheath, the wrapped armour in galvanized steel strip gap, outer protective polyethylene cover are set outward at cable core, make cable there is superior shielding, heatproof, protection against the tide, resistance to compression, anti-animal tooth and the function such as sting, meet the requirement to cable of high-speed railway and heavy traction completely.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
