Abstract
The application discloses a production method for a high-performance data cable. The production method comprises the following steps of: step 1, using a series extruder, and coating an inner insulation layer outside a metal conductive wire in an extrusion moulding mode to form a single-core wire cable; step 2, carrying out pair-twisting on two single-core wire cables extruded with the insulation layers respectively in the step 1 by using a back-twist pair-twisting machine to form a twisted-pair wire cable; step 3, carrying out sub-unit twisting on the twisted-pair wire formed in the step 2 by using a cage winch to form a sub-unit wire cable, and carrying out back-twist on the twisted-pair wire by using the back-twist function of the cage winch during a twisting process; step 4, twisting a plurality of the sub-unit wire cables by using a single twister to form an assembled wire cable; step 5, extruding a sheath outside the assembled wire cable by using a Phi90 sheath extruder. By using the cage winch with the back-twist function in the step 3, no breakage to the twist distance of the twisted-pair wire cable during sub-unit cabling is ensured, and crosstalk is reduced; cabling is carried out by being divided into two steps, thus influence on the pitch of the twisted-pair wire during cabling is furthest reduced.

Background technology
From market demand situation, common service cable and the current domestic production capacity of data cable are greater than demand, and the demand of advanced networks data cable product is in further increasing, but domestic reliablely and stablely to do qualified producer very few.The demand of multipair number (8P, 16P, 24P, 32P, 64P etc.) the high-performance VDSL2 service cable of high-end overseas market demand is also in increasing.VDSL2 is up-to-date is also state-of-the-art xDSL broadband cable communication standard.It can be applied to communication in equipment room, equipment and connect, or user's relaying, connecting system.Wherein the product such as special construction such as star quad stranding, armouring, special certification, particular/special requirement adopts LSZH plastics mostly, also higher to the requirement of material.
Asymmetrical communication cable mainly ensures the impedance uniformity of cable with the stability of the uniformity of single line and subsequent handling, optimize cross-talk performance with Cable Construction Design (pair twist, stranding, shielding and sheath).Product design difficult point is effective cooperation of pair twist, stranding, shielding and sheath operation, to optimize cross-talk performance.
Summary of the invention
The application overcomes shortcoming of the prior art, provides a kind of production method of high-performance data cable, and the cable resistance adopting the method to produce is even, cross-talk function admirable.
In order to solve the problems of the technologies described above, the application is achieved through the following technical solutions:
A production method for high-performance data cable, comprises the following steps:
Step one: use tandem extruder, by extrusion molding mode at the outside coated inner insulating layer of plain conductor, forms single core cable;
Step 2: use back twist pair twister by two through step one respectively extrusion molding have the single core cable of insulating barrier to carry out pair twist, form twisted pair wire;
Step 3: use cage winch to carry out subunit to the twisted-pair feeder formed through step 2 stranded, forms subelement cable, and in stranding process, the back twist function of use cage winch carries out back twist to twisted-pair feeder;
Step 4: use single twist cabling machine to carry out stranded to many strips unit cable, form assembly cable;
Step 5: adopt Φ 90 sheathing machine to extrude sheath outside assembly cable.
Described by extrusion molding mode at the outside coated inner insulating layer with bi-material of wire, specifically comprise: after two kinds of insulating material melts, by extrusion molding in two outlets simultaneously guiding line; The inner insulating layer with bi-material is formed after supercooling.
Bundling machine bundle unit cable tighten can also be used in described step 3.
The twisting pitch of described twisted pair wire is 2.5cm-3.5cm.
The twisting pitch of described subelement cable is 5cm-10cm.
The twisting pitch of described subelement cable is 8cm.
The back twist rate of described cage winch to described twisted-pair feeder is 8%-15%.
The back twist rate of described cage winch to described twisted-pair feeder is 10%.
The twisting pitch of described assembly cable is 5cm-10cm.
The twisting pitch of described assembly cable is 8cm.
Compared with prior art, the beneficial effect of the application is:
(1) production method of a kind of high-performance data cable described in the application, step 2 uses the pair twister with back twist function that two single core cables are twisted into twisted pair wire, can ensure the uniformity of twisted pair wire, the concentricity of single line, ovality are to realize excellent cross-talk performance.
(2) during prior art stranding, line is turned round owing to can produce irregular adding under the effect of laying up pitch, thus destroys the pitch of pair twist.Step 3 uses the cage winch with back twist function, can not destroy the lay of twisted pair wire, ensure pair twist laying up pitch stability, reduce cross-talk when ensure that subunit stranding.
(3) stranding is divided into two steps to carry out, and carries out back twist when subunit twisted synthesizing cable, the impact to the full extent on twisted-pair feeder pitch during minimizing stranding, ensures the uniformity of cable, reduces cross-talk.
(4) not only can set different twisting pitch when subunit is stranded, and with bundling machine cable core tighten, thus can ensure that guarantee structure is more stable, prevent line to mutual displacement.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present application, is used from explanation the application, does not form the restriction to the application with the embodiment one of the application, in the accompanying drawings:
Fig. 1 is the schematic flow sheet of the production method of a kind of high-performance data cable described in the application.
Embodiment
Be described below in conjunction with the preferred embodiment of accompanying drawing to the application, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the application, and be not used in restriction the application.
As shown in Figure 1, the production method of a kind of high-performance data cable described in the application, comprises the following steps:
Step one: insulating exruded, uses tandem extruder, by extrusion molding mode at the outside coated inner insulating layer of plain conductor, forms single core cable;
Step 2: pair twist, use back twist pair twister by two through step one respectively extrusion molding have the single core cable of insulating barrier to carry out pair twist, form twisted pair wire;
Step 3: subunit is stranded, uses cage winch to carry out subunit to the twisted-pair feeder formed through step 2 stranded, forms subelement cable, and in stranding process, the back twist function of use cage winch carries out back twist to twisted-pair feeder;
Step 4: total stranding, uses single twist cabling machine to carry out stranded to many strips unit cable, forms assembly cable;
Step 5: sheathing, adopts Φ 90 sheathing machine to extrude sheath outside assembly cable.
By extrusion molding mode at the outside coated inner insulating layer with bi-material of wire, specifically comprise: after two kinds of insulating material melts, by extrusion molding in two outlets simultaneously guiding line; The inner insulating layer with bi-material is formed after supercooling.
Bundling machine bundle unit cable tighten can also be used in step 3.
The twisting pitch of twisted pair wire is 3cm.It is optimized selection.
The twisting pitch of subelement cable is 8cm.
