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, high speed motor car is adopted in passenger traffic, and the 2nd, the heavy duty traction of the marshalling of growing up is adopted in shipping.High speed motor car and heavy duty traction are had higher requirement to fail safe and comfortableness; In the existing internal screening railway digital signal cable production process; The coating of shielding mainly is the mode that adopts wrapped or vertical bag, and the internal screening railway digital signal cable that adopts this dual mode to produce through regular meeting the quality problems that copper strips bottom pour ladle or copper strips seam crossing split takes place; Because the non-conductive slit that the discontinuous and shield different piece junction of shield forms; The capital produces electromagnetic leakage, has had a strong impact on the shielding properties of cable, causes great potential safety hazard to railway transportation.
Summary of the invention
The present invention seeks to provides a kind of copper strips welding embossing internal screening railway digital signal cable for the deficiency that overcomes existing internal screening railway digital signal cable technology.
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 outer sheath of 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 the copper conductor periphery; Said insulated single wire periphery is surrounded with the bundle yarn, and said bundle yarn is disposed with inboard non-hygroscopic insulating barrier, copper strips welding embossing screen and outside non-hygroscopic insulating barrier outward, and said sheath comprises PET band lapping layer, aluminium sheath, polyethylene bonding sheath, the wrapped armour in galvanized steel strip gap and oversheath from the inside to the outside successively.
Preferably, be provided with the earial drainage lead between described inboard non-hygroscopic insulating barrier and the copper strips welding embossing screen.
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 the slit, can not produce electromagnetic leakage, and shield effectiveness is good.In addition, copper strips welding embossing screen is firm, not yielding, and cable has advantages of higher tensile strength and bending property; Simultaneously; Through PET band lapping layer, aluminium sheath or composite sheath, polyethylene bonding sheath, the wrapped armour in galvanized steel strip gap, polyethylene oversheath are set outside cable core; Make cable have superior shielding, heatproof, protection against the tide, resistance to compression, anti-animal tooth and function such as sting, satisfy high-speed railway and heavy duty traction requirement fully cable.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a copper strips welding embossing internal screening railway digital signal cable structural representation of the present invention.
Among the figure: 1, shielding quad; 2, insulated single wire; 3, copper conductor; 4, insulating barrier; 5, prick yarn; 6, inboard non-hygroscopic insulating barrier; 7, earial drainage lead; 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 accompanying drawing and embodiment:
A kind of copper strips welding embossing internal screening railway digital signal cable shown in Figure 1; Comprise cable core, be coated on the outer sheath of 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; Said insulated single wire 2 peripheries are surrounded with pricks yarn 5, and said bundle yarn 5 is outer to be disposed with inboard non-hygroscopic insulating barrier 6, copper strips welding embossing screen 8 and outside non-hygroscopic insulating barrier 9, and said sheath comprises PET band lapping layer 10, aluminium sheath 11, polyethylene bonding sheath 12, the wrapped armour 13 in galvanized steel strip gap and oversheath 14 from the inside to the outside successively.
Be provided with the earial drainage lead between described inboard non-hygroscopic insulating barrier and the copper strips welding embossing screen.
Described insulating barrier is three-layer co-extruded skin-bubble-Pi physical blowing structure.
Said bonding sheath is the polyethylene bonding sheath.
Said oversheath is the polyethylene oversheath.
During making; Insulated single wire with four different colours is twisted into quad earlier; And wrapped outside bundle yarn 5 and the inboard non-moist insulating barrier 6 of coating; Then earial drainage lead 7 is arranged on the inboard non-hygroscopic insulating barrier 6, adopts the embossing bonding machine to utilize the argon arc welding continuous welding process, copper strips vertically is welded into pipe is coated on the insulated single wire 2 of said four mutually stranded settings of different colours that are coated with inboard non-hygroscopic insulating barrier 6 and carries out embossing again; Outside copper strips welding embossing screen 8, coat the non-moist insulating barrier 9 in the outside again behind the embossing; Again with the stranded together cable core of processing of all line groups, outside cable core, coat the wrapped armour of PET band lapping layer 10, aluminium sheath 11, bonding sheath 12, galvanized steel strip gap 13, oversheath 14 then successively, promptly process copper strips welding embossing internal screening railway digital signal cable of the present invention.Said aluminium sheath 11 can also be a composite sheath.
