Definitions
- the present invention relates to a cable telecommunications comprising at least two groups of twisted metal wires having different pitches and particularly improvements to the manufacture of a telecommunications cable with pairs or symmetrical quads.
- Bandwidth of pair or quart of insulated conductors exceeds currently the gigahertz.
- the properties of transmission required for these cables become of increasingly difficult to satisfy, in particular because the electrical symmetry of the pairs or quartes must be more and more precise.
- An insulated conductor wire must be perfectly centered along the longitudinal axis of the pair or the fourth, typically with an eccentricity less than a few micrometers, do not present fluctuation in diameter as well for the wire metallic, said core, only for the insulating sheath of the insulated lead wire, and have insulation perfectly homogeneous. Capacity fluctuation resulting from geometric heterogeneities and / or materials constituting the metal wire and the sheath insulation must be around 1 to 2 pF / m maximum.
- the metal wire is annealed to find in a metallographic state in which it can support downstream grouping operations with other threads, for example pairing or quartering or assembly and sheathing of pairs or fourths.
- a good compromise is a medium annealing allowing the thread to keep a some flexibility.
- One wire not enough annealing is not flexible enough, and a wire too annealed distorts too much.
- metal wires all have the same initial metallographic state.
- the metallographic constraints on the wires metallic pairs or quads are different in the traditional manufacturing processes of telecommunications cables in pairs or quads symmetrical.
- Metallographic constraints differ between pairs or quads because they must have different pitches for the cable multi-pair or multi-card presents good crosstalk.
- the helix of the conducting wires insulated distorts the lead wire. It is particularly curved and twisted, which generates particular of local constraints by compression and traction caused by the elongation of one edge of the wire compared to each other. These deformations, and therefore the constraints generated, are all the more important that the propeller pitch is short. The footsteps different pairs or quads so cause different constraints in the wires.
- the rotational speeds equal to number of revolutions per minute of lyres in pairing or quartering machines to twist the wires insulated conductors in pairs or quads are different from one pairing or quartering machine to another so that the twisting steps are different in pairs or quads. Centrifugal forces in the lyres are thus different between the sons of different pairs or quads, causing different constraints in the wires.
- a short twist pitch in a pair subjects the son of the pair at relatively constraints high and gives the wires a high strain hardening
- a no twist in another pair typically greater than 24mm subjects the wires to the pair at relatively weaker constraints and gives the wires a low strain hardening.
- the invention aims to provide a cable of the type defined in the entry in material with characteristics of transmission, crosstalk or crosstalk by example, between weaker groups than those of known cables, and a method of manufacturing this cable compensating for the different stresses undergone in metallic wires due to differences in no twisting between groups of wires contained in the cable.
- the first aforementioned objective is achieved thanks to a telecommunication cable comprising groups of twisted metal wires having pitches different, which is characterized by states metallographic metallic wires in all substantially identical groups.
- Each group of wires is preferably a pair of wires or a fourth son.
- the quasi-identity of metallographic states metal wires in the cable of the invention is represented by a work hardening rate or a elongation at break of the wires, the variation of which is significantly less than 1.5%, compared at a variation of at least 6% in a cable traditional.
- the invention thus improves from 4 to 5 dB cable crosstalk.
- the second objective mentioned above concerns improvements made to a process manufacture of a telecommunication cable containing groups of twisted metal wires having no different, including steps to manufacture conductive wires insulated with metallic wires having undergone at least one annealing and sheathing, twist the insulated conductors in groups of twisted yarns with different pitches, and to assemble the groups of wires by twisting them together to constitute said cable.
- This second objective is achieved by imposing states different metallographic groups of wires metallic at least at a predetermined stage of the process other than during the twist step sons in groups, to compensate respectively for differences in metallographic states of wires between the groups of wires at the stage of twisting the wires in groups and confer metallographic states substantially identical to all metal wires of the fabricated cable.
- the states metallographic groups of wires after step to twist the wires in groups with steps different are different, and this difference is maintained in manufacturing processes traditional until the cable is finished.
- said difference is compensated for at minus a predetermined stage during the process of manufacture of the cable which can be located at the level of the grouping of insulated conductors into groups of twisted wires, such as pairs or quads, or during the production of insulated conductors, or at the level of assembling groups of wires twisted in said cable, according to first, second and third achievements.
- said difference can be made up to two or three predetermined stages according to at least two of these three favorite achievements.
- the step of imposing different metallographic states includes a step of exerting different tensions on groups of insulated conductors after the step of make insulated lead wires and before the step of twisting the wires in groups. For example, different tensions are exerted between sets of coils from which the wires isolated conductors of the groups are drawn and several means for twisting the conducting wires isolated drawn in groups. Compensation for different metallographic states of the wire group at the stage of twisting the wires in groups is then obtained by tensions which are exerted on the groups of insulated conductors which vary in the same meaning as the steps of groups from group to group the other.
- the step of imposing different metallographic states includes a step of imposing different parameters on annealing groups of metal wires.
- said parameters are temperatures and / or annealing times of groups of metal wires.
- the compensation of different metallographic states groups of wires at the stage of twisting the wires in groups is then obtained by imposed parameters annealed groups of metal wires which vary in the opposite direction to the steps of the groups of a group to another. These different anneals are obtained during the manufacturing operation of the insulated wire which is a tandem wire drawing / annealing / insulation operation.
- the step to impose different metallographic states includes a step to exercise different tensions on the groups of wires twisted between the step of twist the wires in groups and the step of assembling son groups. For example, tensions different are exerted between coils since which the groups of twisted wires are drawn, and a means for twisting and / or sheathing the groups drawn from wires twisted in said cable. The compensation of different metallographic states of the group of wires at the stage of twisting the wires in groups is then obtained by tensions exerted on the groups of twisted wires which vary in the same sense as the steps of groups from group to group the other.
- Figures 1 and 2 show two types of group insulated conductive wires to which reference will be made below as an example, each group comprising at least two wires intended for transmitting high frequency data.
- a symmetrical pair P is a group of two insulated conductors twisted F1 and F2.
- a fourth symmetrical Q is a group of four wires split into two twisted pairs of wires insulated conductors F3-F5 and F4-F6.
- each pair F1-F2, F3-F5 and F4-F6 is symmetrical about the axis longitudinal of the group and each thread describes a helix around the longitudinal axis of the cable with a constant p between a few millimeters and a few tens of millimeters.
- Each insulated conductor F1 to F6 includes a FM metal wire, also called soul, for example in copper, and an individual GF insulating sheath surrounding the FM metal wire, in material thermoplastic, such as polyethylene or solid or cellular polypropylene, or cellular and massive.
- material thermoplastic such as polyethylene or solid or cellular polypropylene, or cellular and massive.
- the diameter of the wire is a few tenths of a millimeter and the outer diameter of the sheath GF is between 0.5 and 1.5 mm approximately.
- the telecommunication cable shown in the Figure 4 is of the flat type and includes two quarters Q1 and Q2 of different steps, also surrounded by an EC screen and a GC external protective sheath.
- the EB blank is stretched into a TF drawing machine comprising several FI dies so that the blank gradually reaches the FM wire diameter. Then the wire drawn wire is annealed in a REC annealing system either Joule effect between two pulleys at potentials different, either induction, or more rarely in an oven, so as to make it more malleable.
- the GF sheath is then developed around the wire metallic annealed in an EX extruder from which the insulated conductor F pulled by a ROF wheel around from which the insulated conductor wire F is wound.
- the wire passes from a state metallographic hardened EM1 in the blank EB to a EM2 annealed metallographic state at system output annealing REC, then at a metallographic state of EM3 annealing on the ROF wheel at the exit of the wire manufacturing.
- the difference between EM1 states and EM2 is due to the stretching constraints which modify the crystallization of the wire leaving the REC annealing system.
- the FM metallic wires in the pairs making up a cable have the same states metallographic EM2 and EM3 when the process of manufacturing a metal wire is well controlled.
- the EM2 metallographic states of the wires metallic FM constituting the pairs are different.
- An insulated wire production line such as that LFF shown in Figure 5 can supply more than two insulated conductors pairing machines, like the one shown in figure 6, or more of a quartering machine, the travel speeds in a LFF line being at least five times higher about that the frame rate in a pairing machine or a quartering machine.
- two insulated conductors F1 and F2 are drawn from two coils BF1 and BF2.
- the two threads isolated F1 and F2 pass through an AEP input ring of a rotating pairing lyre LYP, are guided on the lyre and then cross an ASP exit ring from the lyre LYP so as to be twisted into a pair P which is pulled and wrapped around a drive wheel ROP.
- the pair is inserted into a sheath tape protection in a sheathing station between the lyre's ASP output ring and the ROP wheel.
- four coils are planned from which the four conductors isolated F3 to F6 constituting the fourth are drawn towards the lyre AEP entry ring.
- the metallic wires FM in the insulated conducting wires F1 and F2 are in a metallographic state EM4 between the coils BF1 and BF2 and the lyre input ring AEP due to a voltage T 4 applied to the entrance to the lyre.
- the metal wires are then in a metallographic state EM5 due to a stress C 5 exerted in the lyre LYP.
- FM metal wires in F1 and F2 wires of the twisted pair at the output of the lyre LYP are at another EM6 metallographic state due to the traction force exerted by the driving wheel ROP.
- the stresses exerted C 5 on the wires during the twisting operation are different when the steps of the pairs or quads are different and the metallographic states EM6 of the wires at the output of pairing machines (quartering machines) are different.
- the rotational speeds R are different between parallel pairers so to feed at the same constant speed in pairs or quartes with different pitches a line assembly and cladding such as that shown in Figure 7 or 8, or the rotational speeds R in the pairers are constant and the speeds linear pairs (or quads) in pairers (or quarters) are adjusted according to the steps different.
- a LASa assembly line assembles groups of insulated conductors which are four pairs P1 to P4 (or four quarters Q1, Q4) depending on the design shown in Figure 7, and wraps them together with a dielectric or polymer-metal complex tape as shown in figure 3, or which are quartes (or pairs) laid lengthwise and wrapped in a EC-GC composite sheath as shown in Figure 4.
- the taping of all the pairs is optional.
- the LASa assembly and taping line shown in Figure 7 includes four coils BP1 to BP4 from which the pairs of conductive wires isolated P1 to P4 are held respectively at through an AEC input ring of a wiring lyre rotating LYC, are guided on the lyre LYC, then cross an ASC output ring to be assembled and twisted into a CP cable which is pulled and wrapped around a ROC drive wheel.
- the coils BP1 to BP4 and the wheels ROP are removed so that pairs P1 to P4 or fourths coming out of pairers or quarterers spend ASP output rings of pairs or quads to the AEC entry ring of the collator if necessary through one or more guide wheels and traction as indicated schematically by the arrow in dotted line on the right in figure 6.
- the CP cable thus constituted can cross a taping station intermediate (not shown) in which a ribbon composite comprising for example the EC screen and the protective sheath GC surrounds all four pairs (or quads) twisted together, coming out of the LYC cable lyre.
- Each metallic wire FM in each of the pairs P1 to P4 is in a metallographic state EM7 between the respective coil BP1 to BP4 and the input ring AEC due to a tensile force T 7 applied to the pair from the Assembly line.
- the metal wire undergoes an assembly and twisting force T 8 applied to the wire in the lyre LYC which defines a metallographic state EM8 of the wire.
- the metal wire is in a final state EM9 at the level of the traction wheel ROC due to a traction force T 9 exerted by the latter.
- the metallographic state of the wire in the sheathing station does not vary.
- the assembly line LASb is a cladding line as shown in FIG. 8. It comprises two coils BP1 BP2 according to the example illustrated, or else four coils, from which groups of insulated conductive wires, by for example pairs P1, P2, or even quads, are unwound and guided to a sheathing station GA and possibly for laying ribbons, where the groups are wrapped together with a composite sheath EC-GC. Then the assembly constituting a cable CP (or CQ) is pulled and wound around a driving wheel ROC.
- a cable CP or CQ
- Each metallic wire FM in each of the groups of wires P1 P2 is in a metallographic state EM7 between the respective coil BP1, BP2 and the sheathing station GA due to a tensile force T 7 applied to the group of wires at the start of the cladding line.
- the metal wire undergoes a force T 8 at the sheathing station, which defines a metallographic state EM8 of the wire.
- the metal wire is in a final state EM9 at the level of the traction wheel ROC due to a traction force T 9 exerted by the latter.
- the object of the invention is to obtain the same final metallographic state EM9 for all FM metal wires contained in the cable, when the cable to be manufactured includes several groups each of at least two sons, such as pairs or quads, despite treatments different from the sons undergone in the pairers (quarters) PA at LYP lyres level due to differences in pitch p in pairs (quads) which confer to metallic wires in pairs (quartes) of different EM5 metallographic states.
- all FM metal wires contained in the wires insulated conductors F are manufactured from the same way in the wire manufacturing line (s) LFF ( Figure 5) and have EM1 metallographic states to EM3 respectively identical.
- State metallographic EM3 of each metallic wire FM is for example characterized by measures known metallographic such as determination of grain size, tensile strength, strength wire strain or strain hardening metallic.
- states metallographic metallic wires are said "substantially identical" when the differences in wire hardening rate compared to states metallographic data considered at similar places in the lines are lower at around 1.5%.
- the linear velocities V are equal so that the pairs (quarts) enter the assembly line and LAG cladding (figure 7) with V speeds identical when the pairers operate in continuous with the LASa or LASb assembly line, and EM6 metallographic states of metallic wires FM in pairs P1 to P4 at the output of the pairers are substantially identical and this sensitive identity of metallographic states is maintained in the stations of the LASa, LASb line.
- the voltages T 4 are respectively determined as a function of the different rotational speeds R of the lyres LYP and therefore of the predetermined steps different p of the pairs.
- the voltage T 4 must vary in opposite direction to the step p.
- the tension T 4 is adjusted to be the lowest; conversely, for the pair having the longest pitch, for example equal to 24 mm , the voltage T 4 is set to be the highest.
- the metallographic states EM6 to EM8 of the metallic wires FM in the pairs (quartes) PA (FIG. 6) between the outputs of the pairers (quartates) and the assembly and sheathing line LAG (FIG. 7) are substantially identical.
- a predetermined metallographic state EM1 to EM3 in the metallic wires FM of each pair produced by the production line or lines LFF (FIG. 5) is different from the predetermined metallographic states in the metallic wires of the other pairs.
- the difference of metallographic behavior of metallic wires in a completed traditional cable is offset by annealing of the groups of wires, i.e. pairs or quads of wires.
- the stress C5 exerted on the wires varies in the opposite direction to the pitch p according to the above-mentioned relationship, for identical voltages T 4 applied to the wires F1 and F2 in the pairing machines.
- the stress C5 exerted on a wire gives it proportional resistance to deformation and therefore proportionally work hardening; thus the smaller the pitch, the higher the work hardening conferred on the pairing (quartering).
- the annealing imparted to a wire metallic in the REC annealing system varies in the opposite direction of the step in order to compensate the work hardening in the pairing machine (quartering machine) which undergoes the wire.
- This annealing can be characterized by several parameters like the rate of work hardening and the elongation at break of the wire.
- annealing the wires metallic of this pair in metallographic state EM2 at the output of the REC annealing system is the most important, that is to say the metal wires of this pair are the most malleable, and the temperature and / or the annealing time of the wires of this pair are the highest. Conversely, for the pair having the not the longest, annealing the metallic wires of this EM2 metallographic pair is the most low, and the annealing temperature and / or duration sons of this pair are the weakest.
- Differences between states metallographic annealing EM2 of metallic wires are for example quantified by the differences between the elongations at break of these wires, in the range of 1 to 12%.
- all the metallic wires FM of the pairs (quads) of the cable are annealed and insulated in the same way, and the metallographic states EM1 to EM4 of the metallic wires FM in the wire production line (s) LFF (FIG. 5) and at the entry into PA pairers (FIG. 6) are respectively substantially identical.
- the metallographic states EM7 of the metallic wires FM in the pairs between the coils BP1 to BP4 and the AEC input ring of the lyre LYC in the assembly line LASa (figure 7), or between the coils BP1 and BP2 and the sheathing station GA in the line LASb assembly lines ( Figure 8), are different.
- the metallographic states EM6 EM7 of the metallic wires in the pairs between the output rings ASP of the pairers and the input ring AEC of the line LASa or the sheathing station GA of the line LASb when the pairers are connected continuously to the LASa line, LASb are different.
- the differences in the metallographic states EM7 are produced by exerting different voltages T 7 on the pairs (quads) P1 to P4, for example by means of wheel or adjustable braking track.
- the shorter the pitch p of a pair the higher the stress C5 and the more the tension T 7 of the pair is adjusted weakly.
- the longer the step p of a pair the higher the voltage to be set T 7 of the pair.
- the voltages T 7 respectively compensate for the stresses C5 so that the final metallographic states EM9 of all the metallic wires FM in the finished cable CP are substantially identical.
- the first, second and third achievements can be combined two by two or all three so that two or three states metallographic EM4, EM2, EM6 different between son groups P1 to P4 compensate for differences metallographic states (EM5) of the groups of wires during groupings, PA pairings or quarterings, due with different steps from the twists of the groups of wires, and so that the final metallographic states EM9 wires in the cable CP, CQ are substantially identical.
