Table 2 short vulcanization chlorinated polyethylene rubber performance indications
When processing photoelectric composite medium-pressure drum cable, process power wire core 1, wire core 2 and light unit the most respectively
3.Conductor in power wire core 1, wire core 2 selects tinned copper wire or bare copper wire, and conductor filament diameter is the thinnest, and flexibility is the best,
The softness of conductor and degree of crook decide bending and the softness of cable, therefore, need especially in cable conductor design
Be particular about.It addition, use between adjacent two layers during conductor strand contrary strand to, every layer strand to the strand of strand in respective layer to
On the contrary, the lay ratio of strand controls at 12-14 times, and outermost lay ratio controls at 10-12 times, from outside to inside the joint of every layer
Footpath than all ratio many 2 numerical value of adjacent outward layer, the most stranded the most resistance to distorting stress of prepared conductor structure, have well
It is compressed axially and bending strength.
In power wire core 1, for ensureing the electric property of cable, at the outer wrapped one layer of semiconductive rubber strap of conductor 11,
I.e. isolation strip.For ensureing the shelf depreciation of midium voltage cable and pressure test, outside in conductor isolation strip is three-layer co-extruded to go out partly to lead
Electric conductor shielding material, Insulation Material, semi-conductive insulation shield material, by the sulfuration process of curing tube according to normally controlling, sulfur
Change completely, form semiconductive conductor shield 12, insulating barrier 13, semi-conductive insulation shield layer 14.Insulating barrier 13 uses high-performance
EP rubbers layer, performance requirement: temperature resistant grade so must can bear the change of day and night temperature between-40 DEG C～90 DEG C,
It also is able to use in the summer of heat and the winter of severe cold simultaneously；It addition, have good electric property and excellent mechanical thing
Rationality energy.
General midium voltage cable also needs to layer of metal shielding, photoelectric composite medium-pressure reel electricity outside semi-conductive insulation shield layer
Cable, due to special working environment, as shielded plus layer of metal at outer layer, can reduce the service life of whole cable.Therefore,
Metallic shield outside insulation is resolved into wire core 2 by us, is dispersed in the master core i.e. both sides of power wire core 1, therefore needs on ground
Extrude one layer of semiconductive shieldin material outside core 2, form semiconductive clad 22, this ensure that the outer institute of insulation semi-conductive screen
It is iso-electric for having core.
In light unit 3, fiber number is preferably 6,12,18 or 24 cores, it is also possible to be other core numbers of requiring of user, optical fiber
Preferably it is made up of the silica optical fiber of coat similar.Same design, identical material and same process should be used with batch product
The optical fiber manufactured.During in light unit, coated fiber should be placed on the Loose tube that thermoplastic is constituted, optical fiber is at Loose tube
In remaining length should be uniform and stable.Loose tube material can use polybutylene terephthalate (PBT) (be called for short PBT) plastics or other are suitable
Plastics.Gap in Loose tube should fill the complex of a kind of thixotropic continuously, and it is special that implant should not damage fiber-optic transfer
Property and service life.Light unit should comprise enough non-metallic stiffener, in order to increase the tensile property of optical cable.This cable
Middle regulation stiffener is aramid fiber, and its Young's modulus is preferably not less than 90Gpa.When processing light unit 3, outside optical fiber, extrude shape
Become PBT Loose tube 31, and the gap in Loose tube 31 are filled high-flash ointment and play heat insulation and protective effect, then will be many
The Loose tube 31 setting optical fiber in individual carries out stranded formation optical cable core, fills out in the internal clearance between plurality of Loose tube 31
It is filled with stiffener aramid fiber, to ensure the tensile strength of light unit.When multiple Loose tube 31 are stranded, twisted layer should be by external diameter phase
Same 5-12 pipe loose tube fiber twists the surrounding at central strength member aramid fiber with suitable pitch layer.Layer strand can be spiral strand, also
It can be SZ strand.After processing optical cable core, upper water resistance aramid fiber is pricked in the outside of this optical cable core, finally on water resistance aramid fiber
Extrude above-mentioned chlorinated polyethylene rubber material, this chlorinated polyethylene rubber material at 130 DEG C ~ 160 DEG C, quick sulfur between 5 ~ 10min
Change, form chlorinated polyethylene rubber sheath 32, fast-curing chlorinated polyethylene rubber sheath 32, it is possible to ensure in the course of processing
Stablizing of optical fiber property.
After processing power wire core 1, wire core 2 and light unit 3, on cabling device by three power wire core 1,
Two wire core 2 and a light unit 3, according to the lay ratio stranding together of no more than 10 times, form cable core 10, at stranding
During, also in the center gap of cable core 10, fill out semiconducting filler material, for example semi-conductive rubber.At cabling device
On, due to the optical fiber in light unit can not stress, so the corresponding frame of cabling device to be set to actively unwrapping wire, it is ensured that optical fiber
Energy；The lay ratio of stranding is not more than 10 times, so ensure that the bending property of whole cable, and ensures that cable core is being subject to
Uniformity during power, extends the service life of cable indirectly.In cabling process, need not band outside cable core 10, so
Can ensure the relative position of cable core 10 after follow-up inner sheath 5 is extruded, in use core Relative sliding is smaller,
Service life is long.
Cable core 10 extrudes above-mentioned speciality CR material, forms speciality CR inner sheath 5, control this spy
Plant the state of cure (vulcanization) of neoprene inner sheath 5 at 40%-60%.Then shape is woven in the outside of speciality CR inner sheath 5
Becoming enhancement Layer 6, the count of this enhancement Layer controls at 30%-50%, and angle of weave controls at 40 °-60 °, due to extraordinary neoprene
The state of cure (vulcanization) of rubber inner sheath 5 controls at 40%-60%, then the enhancement Layer 6 woven protects in being embedded in speciality CR
In set 5.On enhancement Layer 6, finally extrude above-mentioned speciality CR material, form speciality CR oversheath 7, this spy
