Cov hlau thiab cables siv qhov ntev raws li qhov yooj yim ntawm kev ntsuas.Tag nrho cov xov hlau thiab cables pib los ntawm kev ua tus neeg xyuas pib, thiab tom qab ntawd ntxiv cov rwb thaiv tsev, thaiv, cabling, sheathing, thiab lwm yam txheej los ntawm txheej nyob rau hauv qhov chaw ntawm tus neeg xyuas pib ua cov khoom siv hlau thiab cable.Qhov ntau cov khoom tsim qauv, ntau txheej yog superimposed.
Cov txheej txheem tsim cov hlau thiab cable
1. Copper, aluminium monofilament daim duab
Feem ntau siv tooj liab thiab txhuas rods rau hlau thiab cable, nyob rau hauv chav tsev kub, siv lub tshuab nqus hlau los ntawm ib los yog ob peb lub qhov tuag ntawm daim duab tuag kom txo tau qhov hla ntu, nce qhov ntev thiab txhim kho lub zog.Hlau daim duab yog thawj txheej txheem ntawm txhua lub tuam txhab xaim thiab cable, thiab cov txheej txheem tseem ceeb ntawm kev kos duab hlau yog pwm txuam tshuab.
2.Monofilament annealed
Thaum cov tooj liab thiab txhuas monofilaments tau rhuab mus rau qhov kub thiab txias, qhov toughness ntawm cov monofilaments tau txhim kho thiab lub zog ntawm cov monofilaments raug txo los ntawm recrystallization, thiaj li ua tau raws li cov kev xav tau ntawm cov xaim hluav taws xob thiab cov cables rau cov cores conductive.Tus yuam sij rau cov txheej txheem annealing yog los tiv thaiv oxidation ntawm tooj liab hlau.
3. Stranding ntawm conductors
Txhawm rau txhim kho qhov muag muag ntawm cov xov hlau thiab cables thiab pab txhawb kev tso thiab teeb tsa, cov tub ntxhais conductive yog twisted nrog ntau lub monofilaments.Los ntawm daim ntawv stranding ntawm cov tub ntxhais conductive, nws muaj peev xwm muab faib ua stranding tsis tu ncua thiab tsis xwm yeem stranding.Cov stranding tsis tu ncua yog muab faib ua beam stranding, concentric stranding, tshwj xeeb stranding, thiab lwm yam.
Txhawm rau txo qhov chaw nyob ntawm cov xov hlau thiab txo qhov geometric loj ntawm lub cable, daim ntawv cog lus tau txais yuav thaum tus neeg xyuas pib raug tso tseg, kom lub voj voog zoo tib yam hloov mus rau hauv ib lub voj voog, kiv cua zoo li, pobzeb puab thiab ib lub voj voog. nruj nreem nias lub voj voog.Hom conductor no tsuas yog siv rau hauv cov fais fab cables.
4. Rwb thaiv tsev extrusion
Yas hlau thiab cable feem ntau siv extruded khoom rwb thaiv tsev txheej.Lub ntsiab kev xav tau rau cov yas rwb thaiv tsev extrusion:
4.1 Eccentricity: Tus nqi sib txawv ntawm extruded rwb thaiv tsev thickness yog ib qho tseem ceeb cim qhia txog qib ntawm extrusion technology.Feem ntau ntawm cov qauv khoom loj thiab nws cov nqi sib txawv tau qhia meej meej hauv tus qauv.
4.2 Smoothness: Qhov saum npoo ntawm extruded insulating txheej yuav tsum tau du, thiab yuav tsum tsis muaj teeb meem tsis zoo xws li nto roughness, burnt, thiab impurities.
4.3 Qhov ntom ntom: Ntu ntu ntawm cov txheej txheej extruded insulating yuav tsum ntom thiab ruaj, tsis muaj pinholes pom ntawm qhov muag liab qab, thiab tiv thaiv kom tsis txhob muaj huab cua npuas.
5. Kab
Rau ntau cov tub ntxhais cables, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, nws yog qhov yuav tsum tau ua tib zoo saib xyuas cov txheej txheem ntawm kev tsim thiab txo cov duab ntawm cov cables, feem ntau yuav tsum tau muab cov hlua khi rau hauv lub voj voog.Lub mechanism ntawm stranding zoo ib yam li cov neeg xyuas pib stranding.Vim lub suab loj ntawm txoj kab uas hla ntawm stranding, feem ntau ntawm lawv tau txais txoj kev tsis rov qab twisting.
Cov kev cai rau kev siv cabling: ib qho yog los tiv thaiv kev sib tw thiab khoov ntawm cov kab hluav taws xob los ntawm kev hloov pauv ntawm cov khoom tshwj xeeb zoo li insulated cores;lwm qhov yog los tiv thaiv cov txheej txheem rwb thaiv tsev los ntawm khawb.
Feem ntau ntawm cov cables yog cabled ua ke nrog kev ua tiav ntawm ob txoj kev ua tiav: ib qho yog sau los xyuas kom meej lub roundness thiab stability ntawm cable tom qab lub cable yog tsim;lwm qhov yog khi kom ntseeg tau tias cov tub ntxhais cable tsis xoob.
6. Sab hauv kev tiv thaiv txheej
Txhawm rau tiv thaiv cov tub ntxhais hlau insulated los ntawm kev puas tsuaj los ntawm cov cuab yeej, nws yog ib qho tsim nyog los tiv thaiv cov txheej txheem rwb thaiv tsev kom zoo.Lub puab sheath tau muab faib ua: extruded puab sheath (lub tes tsho cais) thiab qhwv puab sheath (cushion).Cov ntaub qhwv cushion hloov daim kab xev khi thiab cov txheej txheem cable-forming yog ua tiav ib txhij.
7. Armor
Cov kab hluav taws xob tso rau hauv av tuaj yeem dais qee qhov zoo ntawm lub zog thaum ua haujlwm, thiab sab hauv steel daim kab xev armored qauv tuaj yeem xaiv.Thaum lub cable tso rau hauv lub ntees nrog ob qho tib si zoo siab thiab nro (xws li nyob rau hauv dej, ntsug ncej los yog av nrog loj poob), cov qauv hom nrog puab hlau hlau armor yuav tsum tau xaiv.
8. Sab nrauv
Sab nrauv sheath yog ib feem ntawm cov txheej txheem uas tiv thaiv txheej rwb thaiv tsev ntawm cov hlau thiab cable los ntawm ib puag ncig yam.Lub luag haujlwm tseem ceeb ntawm lub tsho sab nrauv yog txhawm rau txhim kho lub zog txhua yam ntawm cov hlau thiab cable, tshuaj lom neeg corrosion, dej tsis kam, dej immersion, thiab muaj peev xwm tiv thaiv cov cable los ntawm kev kub hnyiab.Raws li cov kev cai sib txawv ntawm lub cable, lub hnab yas yog ncaj qha extruded los ntawm extruder.
