Describe the invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
A kind of zip mode sleeve pipe internal screening railway digital signal cable, as it is shown in figure 1, include cable core and It is coated on the sheath outside cable core;Described cable core includes that at least one shields quad 1, this shielding four line The insulated single wire 2 that group 1 includes mutually stranded four piece different colours, described insulated single wire 2 outside by interior extremely It is sequentially provided with outward bundle layer 5, inner side non-hygroscopic insulating barrier 6, zip mode liner shields layer 8 and outside Non-hygroscopic insulating barrier 9;Described sheath includes PET strip lapping layer 10, aluminium sheath layer the most successively 11, bonding sheath 12, armor 13 and external sheath layer 14.Inner side non-hygroscopic insulating barrier 6 with draw Being provided with earial drainage wire 7 between chain type liner shields layer 8, signal transmission is stable, fluctuates little, this cable Anti-electromagnetic interference capability strong.
Described cable core can include two shielding quads 1.Insulated single wire 2 therein is by copper conductor 3 He It is coated on this insulating barrier 4 outside copper conductor 3 to form.Wherein, described insulating barrier 4 is skin-bubble-skin Three-layer co-extruded physical blowing structure.Insulating resistance of cable can be effectively improved, reduce the sending allowance of cable, Reduce the mutual capacitance of cable, thus be greatly improved the security reliability of cable.
Armor 13 uses the wrapped armor in galvanized steel strip gap, and production efficiency is high, low cost of manufacture, Structural strength is high, is unlikely to deform, and cable has higher tensile strength and bending property.It should be noted that, Above-mentioned aluminium sheath layer 11 is possible not only to use aluminium sheath, it is also possible to use composite sheath as required.Viscous Knot sheath generally selects polyethylene bonding sheath.
Above-mentioned zip mode liner shields layer 8 includes crocheted net and the hook of the copper free wire crocheted of inner side Polyester multifilament braid outside knitmesh, is provided with along described zip mode liner shields layer 8 length direction Slide fastener.It should be noted that the zip mode shielded tube that the technology that meets requires can commercially be bought, this Sample can save middle production link, reduces quality of production risk, improves shielding quad production efficiency.
Above-mentioned bonding sheath 12 is bonding sheath, and external sheath layer 14 uses outer protective polyethylene set.
Make this cable time: first cut-and-dried zip mode shielded tube is contained in special threading device Upper standby, then the insulated single wire of four different colours is twisted into quad, and at it outside around wrapping yarn 5 and cladding inside non-moist insulating barrier 6, then earial drainage wire 7 is arranged on inner side non-hygroscopic insulation On layer 6, then by threading device, zip mode liner shields layer 8 is directly sleeved on and is coated with bundle yarn 5 and interior In the quad of the non-moist insulating barrier 6 in side, and disposably complete suit.Confirm zip mode shielded tube Slide fastener be in closure state after, non-moist insulating barrier outside the outer cladding the most again of zip mode liner shields layer 8 9, make a shielding quad 1, afterwards several shielding quads 1 are made by twisting cable core together, then Be coated with successively outside cable core PET strip lapping layer 10, aluminium sheath layer 11, bonding sheath 12, armor 13, And oversheath 14.
The invention uses zip mode liner shields layer, and production efficiency is high, steady quality, it is easy to install And dismounting, easy to use.Simultaneously so that cable flexibility is good, is unlikely to deform, tensile strength and bending Performance is good, has high-sensitive electromagnetic interference shield function, has noise reduction, dust-proof, flame-proof abrasion-resistant simultaneously Performance.The sheath that cable core is arranged makes cable have superior shielding, heatproof, protection against the tide, resistance to compression, anti-animal Tooth stings function, meets the requirement to cable of high-speed railway and heavy traction.
The foregoing is only the preferred embodiment of the invention, not in order to limit present invention wound Make, within all spirit in the invention and principle, any modification, equivalent substitution and improvement made Deng, within should be included in the protection domain of the invention.
