Cov hlua hluav taws xob tau tsim txhua hnub. Cov hlua hluav taws xob muaj ntau dua 100, 000 meters ib hnub thiab muaj 50, 000 ntsaws. Nrog xws li ib tug loj npaum li cas ntawm cov ntaub ntawv, cov txheej txheem ntau lawm yuav tsum ruaj khov thiab paub tab. Tom qab kev tshawb nrhiav txuas ntxiv thiab kev tshawb fawb thiab kev pom zoo los ntawm European VDE daim ntawv pov thawj lub cev, lub teb chaws tus qauv CCC daim ntawv pov thawj lub cev, American UL ntawv pov thawj lub cev, British BS ntawv pov thawj lub cev, Australian SAA ntawv pov thawj lub cev, thiab lwm yam., lub hwj chim qaum plug tau matured. Cia peb qhia hauv qab no:
1. Fais fab qaum tooj liab thiab txhuas monofilament teeb duab
Cov tooj liab thiab txhuas rods feem ntau siv rau hauv cov hlua hluav taws xob yog siv los hla ib lossis ob peb lub qhov tuag ntawm ib qho kev tuag ntawm chav tsev kub kom txo tau qhov cross-section, nce qhov ntev thiab txhim kho lub zog. Kev kos duab yog thawj txheej txheem ntawm txhua lub tuam txhab xaim thiab cable, thiab cov txheej txheem tseem ceeb ntawm kev kos duab yog cov pwm txuam tshuab.
2. Fais fab qaum monofilament annealing
Thaum cov tooj liab thiab txhuas monofilaments tau rhuab mus rau qhov kub thiab txias, qhov toughness ntawm monofilament yog txhim kho thiab lub zog ntawm monofilament raug txo los ntawm cov txheej txheem ntawm recrystallization, thiaj li ua tau raws li qhov yuav tsum tau ntawm cov xaim thiab cable rau cov tub ntxhais conductive. Tus yuam sij rau cov txheej txheem annealing yog tshem tawm cov oxidation ntawm tooj liab hlau.
3. Stranding ntawm lub hwj chim kab conductors
Txhawm rau txhim kho qhov hloov pauv ntawm txoj hlua hluav taws xob kom yooj yim installation, cov tub ntxhais conductive yog tsim los ntawm kev sib tw ntau lub monofilaments. Los ntawm txoj kev twisting ntawm cov tub ntxhais hlau conductive, nws tuaj yeem muab faib ua cov twisting tsis tu ncua thiab tsis sib xws. Non-regular stranding yog ntxiv muab faib ua bundling stranding, concentric compound stranding, thiab extraordinary stranding. Txhawm rau txo qhov chaw nyob ntawm cov xaim thiab txo cov geometric loj ntawm cov kab hluav taws xob, tus neeg xyuas pib stranded kuj compressed, kom lub voj voog zoo tib yam tuaj yeem hloov mus rau hauv ib lub voj voog, kiv cua zoo li, pobzeb puab thiab lub voj voog compressed. . Hom neeg xyuas pib no feem ntau yog siv rau cov kab hluav taws xob.
4. Fais fab qaum rwb thaiv tsev extrusion
Cov hlua hluav taws xob yas yog tsim los ntawm extruded khoom rwb thaiv tsev txheej. Lub ntsiab kev xav tau rau cov yas rwb thaiv tsev extrusion:
1) Eccentricity: Tus nqi sib txawv ntawm extruded rwb thaiv tsev thickness yog lub ntsiab qhia ntawm qib ntawm extrusion workmanship. Feem ntau ntawm cov khoom tsim qhov ntev thiab lawv qhov sib txawv qhov tseem ceeb muaj cov cai meej hauv cov lus qhia.
2) Lubricity: Qhov saum npoo ntawm txheej extruded insulating yuav tsum tau lubricated, thiab yuav tsum tsis txhob muaj teeb meem tsis zoo xws li ntxhib tsos, scorching, thiab impurities.
3) Qhov ntom ntom: Ntu ntu ntawm cov txheej txheej extruded insulating yuav tsum ntom thiab muaj zog, tsis muaj pinholes pom ntawm qhov muag liab qab, thiab tsis muaj npuas.
5. Cov hlua hluav taws xob yog xaim
Rau ntau cov tub ntxhais fais fab qaum, txhawm rau txhawm rau txhawm rau txhim kho thiab txo qhov zoo ntawm cov hlua hluav taws xob, nws yog ib qho tsim nyog yuav tsum tau tig lawv mus rau hauv ib lub voj voog. Cov txheej txheem ntawm kev sib tw yog zoo ib yam li cov neeg xyuas pib twisting, vim hais tias cov twisting pitch yog loj, thiab lawv feem ntau siv txoj kev tsis muaj rov qab twisting. Cov kev cai rau kev siv cabling: Ua ntej, kev sib tw ntawm lub cable tshwm sim los ntawm kev sib tw ntawm cov tub ntxhais insulated hlau; Qhov thib ob yog los tiv thaiv cov txheej insulating los ntawm khawb.
Feem ntau ntawm cov cables kuj tau ua tiav nrog ob txoj hauv kev thaum lub sij hawm tsim cable: ib qho yog filling, uas ua kom lub roundness thiab stability ntawm cable tom qab lub cable yog tsim; lwm qhov yog bundling, uas xyuas kom meej tias cov tub ntxhais cable tsis xoob.
6. Sab hauv cov hlua hluav taws xob
Txhawm rau tiv thaiv cov tub ntxhais insulated los ntawm kev puas tsuaj los ntawm cov cuab yeej, nws yog ib qho tsim nyog los tiv thaiv cov txheej txheem insulating kom zoo. Lub puab sheath tau muab faib ua: extruded puab sheath (kab cais) thiab qhwv puab sheath (cushion txheej). Kev hloov ntawm daim kab xev khi los ntawm cov ntaub qhwv cushion yog ua tiav ib txhij nrog cov txheej txheem cabling.
7. Fais fab caj npab
Tso rau hauv cov kab hluav taws xob hauv av, nws tuaj yeem lees txais qee qhov txiaj ntsig zoo thaum lub sijhawm ua haujlwm, thiab sab hauv steel daim kab xev armored qauv tuaj yeem xaiv. Cov hlua hluav taws xob tau muab tso rau hauv ib qho chaw uas muaj cov txiaj ntsig zoo thiab cov nyhuv nro (xws li dej, ntsug ncej lossis av nrog qhov poob loj).
8. Cov hlua hluav taws xob sab nraud
Sab nrauv sheath yog ib feem ntawm cov txheej txheem uas tiv thaiv txheej rwb thaiv tsev ntawm cov hlua hluav taws xob los ntawm corrosion ntawm ib puag ncig cov ntsiab lus. Cov txiaj ntsig tseem ceeb ntawm cov txheej txheem sab nrauv yog txhawm rau txhim kho cov khoom siv hluav taws xob ntawm lub zog hluav taws xob, tiv thaiv tshuaj lom neeg yaig, pov thawj noo noo, tsis muaj dej tsis txaus, thiab tiv thaiv kom tsis txhob muaj hluav taws xob hluav taws xob. Raws li cov kev xav tau sib txawv ntawm cov hlua hluav taws xob, lub hnab yas yog ncaj qha extruded los ntawm extruder.
