Description
Technical field
The utility model 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 traction of the marshalling of growing up is adopted in shipping.High speed motor car and heavy 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; the internal screening railway digital signal cable that adopts this dual mode to produce; the quality problems that copper strips bottom pour ladle or copper strips seam crossing split often can occur; because the non-conductive slit that the discontinuous and shield different piece junction of shield forms; the capital produces electromagnetic leakage; have a strong impact on the shielding properties of cable, caused great potential safety hazard to railway transportation.
Summary of the invention
The utility model purpose is that a kind of copper strips welding embossing internal screening railway digital signal cable is provided for the deficiency that overcomes existing internal screening railway digital signal cable technology.
The utility model 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 comprised of copper conductor and the insulating barrier that is coated on the copper conductor periphery, described insulated single wire periphery is surrounded with the bundle yarn, described bundle yarn is disposed with inboard non-hygroscopic insulating barrier outward, copper strips welding embossing screen and outside non-hygroscopic insulating barrier, described sheath comprise PET band lapping layer from the inside to the outside successively, aluminium sheath, the polyethylene bonding sheath, the wrapped armour in galvanized steel strip gap and oversheath.
Preferably, be provided with the earial drainage wire 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 utility model 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 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 outside cable core, make cable have superior shielding, heatproof, protection against the tide, resistance to compression, anti-animal tooth and the function such as sting, satisfy high-speed railway and heavy traction fully to the requirement of cable.
