Tshawb nrhiav cov txheej txheem ntau lawm ntawm European Standard Yas Coated Aluminium Daim kab xev Shielded Composite Sheath

Thaum cov kab hluav taws xob tau muab tso rau hauv av, hauv qhov chaw hauv av lossis hauv cov dej uas nquag ua rau cov dej nkag mus, txhawm rau tiv thaiv cov dej vapor thiab dej los ntawm kev nkag mus rau hauv cov kab hluav taws xob rwb thaiv tsev thiab xyuas kom lub neej kev pab cuam ntawm lub cable, lub cable yuav tsum tau txais kev pab cuam lub neej. radial impervious barrier txheej txheej, uas muaj xws li ib tug hlau sheath thiab ib tug hlau-yas composite sheath. Lead, tooj liab, txhuas thiab lwm yam ntaub ntawv hlau feem ntau yog siv los ua hlau sheaths rau cables; Ib daim kab xev hlau-yas sib xyaw thiab polyethylene sheath tsim cov hlau-yas sib xyaw sheath ntawm ib lub cable. Hlau-yas composite sheathing, tseem hu ua kev sheathing, yog tus yam ntxwv los ntawm softness, portability, thiab dej permeability yog npaum li cas me dua yas, roj hmab sheathing, haum rau cov chaw uas muaj siab waterproof kev ua tau zoo, tab sis piv nrog hlau sheathing, hlau-yas composite sheathing tseem muaj qee yam permeability.

Nyob rau hauv European nruab nrab voltage cable qauv xws li HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, ib leeg-sab coated yas coated txhuas daim kab xev yog siv raws li ib tug kev waterproof cover rau fais fab cables. Hlau txheej ntawm ib sabyas coated aluminium daim kab xevyog nyob rau hauv kev sib cuag ncaj qha nrog insulating ntaub thaiv npog, thiab plays lub luag hauj lwm ntawm hlau ntaub thaiv npog tib lub sij hawm. Nyob rau hauv cov txheej txheem European, nws yog ib qho tsim nyog los ntsuas lub zog stripping ntawm cov yas coated aluminium daim kab xev thiab cov cable sheath thiab ua cov kev ntsuam xyuas corrosion los ntsuas cov dej radial ntawm cable; Nyob rau tib lub sijhawm, nws tseem yuav tsum ntsuas qhov DC tsis kam ntawm cov yas coated aluminium daim kab xev los ntsuas nws lub peev xwm nqa luv luv Circuit Court tam sim no.

1. Kev faib tawm ntawm cov yas coated aluminium daim kab xev
Raws li qhov sib txawv ntawm cov yas zaj duab xis coated nrog aluminium substrate cov khoom, nws tuaj yeem muab faib ua ob hom txheej txheej txheej txheej ntev: ob sab yas coated aluminium daim kab xev thiab ib sab yas coated txhuas daim kab xev.
Cov txheej txheem dej tsis muaj dej thiab noo noo-pov thawj tiv thaiv txheej nruab nrab thiab qis hluav taws xob hluav taws xob cables thiab kho qhov muag cables muaj li ntawm ob sab yas coated aluminium daim kab xev thiab polyethylene, polyolefin thiab lwm yam sheathing plays lub luag hauj lwm ntawm radial dej thiab noo noo-pov thawj. Ib leeg-sab yas coated aluminium daim kab xev feem ntau yog siv rau hlau thaiv kev sib txuas lus cables.

Hauv qee cov qauv European, ntxiv rau kev siv los ua cov ntaub thaiv dej tsis zoo, ib leeg-sab yas coated aluminium daim kab xev kuj tseem siv los ua cov ntaub thaiv hlau rau cov kab hluav taws xob nruab nrab, thiab txhuas daim kab xev tiv thaiv muaj txiaj ntsig zoo dua piv nrog tooj liab thaiv.

2. Longitudinal wrapping txheej txheem ntawm yas coated txhuas daim kab xev
Cov txheej txheem ntev wrapping ntawm aluminium-yas composite sawb yog hais txog cov txheej txheem ntawm kev hloov cov yas coated aluminium daim kab xev los ntawm qhov qub tiaj tus duab mus rau lub raj zoo los ntawm ntau cov pwm deformation, thiab kev sib txuas ntawm ob npoo ntawm cov yas coated aluminium daim kab xev. Ob lub npoo ntawm cov yas coated aluminium daim kab xev yog tiaj thiab du, cov npoo yog sib txuas kom nruj, thiab tsis muaj txhuas-yas tev.

Cov txheej txheem ntawm kev hloov cov yas coated aluminium daim kab xev los ntawm cov duab tiaj tus mus rau cov duab tubular tuaj yeem pom tau los ntawm kev siv cov kab ntev ntev wrapping tuag uas muaj cov kab ntev wrapping horn tuag, kab stabilizing tuag thiab sizing tuag. Daim duab ndlwg ntawm longitudinal wrapping molding tuag ntawm cov yas coated aluminium daim kab xev yog qhia hauv daim duab hauv qab no. Ob lub npoo ntawm tubular yas coated txhuas daim kab xev tuaj yeem sib txuas los ntawm ob txheej txheem: kev sib txuas kub thiab kev sib txuas txias.

(1) Cov txheej txheem kub sib txuas
Cov txheej txheem thermal bonding yog siv cov yas txheej ntawm cov yas coated txhuas daim kab xev kom muag ntawm 70 ~ 90 ℃. Nyob rau hauv cov txheej txheem deformation ntawm cov yas coated aluminium daim kab xev, cov txheej txheem yas ntawm qhov sib koom ua ke ntawm cov yas coated aluminium daim kab xev yog rhuab siv lub tshuab cua kub los yog blowtorch nplaim, thiab ob lub npoo ntawm cov yas coated txhuas daim kab xev yog sib koom ua ke siv cov viscosity. tom qab softening ntawm cov yas txheej. Muab ob lub npoo ntawm cov yas coated aluminium daim kab xev kom ruaj khov.

(2) Cov txheej txheem sib khi txias
Cov txheej txheem kev sib txuas txias tau muab faib ua ob hom, ib qho yog ntxiv rau qhov ntev ruaj khov tuag nyob rau hauv nruab nrab ntawm lub caliper tuag thiab lub taub hau extruder, kom cov yas coated aluminium daim kab xev tuav ib tug kuj ruaj khov tubular qauv ua ntej nkag mus rau lub taub hau ntawm lub extruder. , qhov tawm ntawm qhov ruaj khov tuag yog ze rau qhov tawm ntawm lub extruder's tuag core, thiab aluminium-yas composite tam sim ntawd nkag mus rau hauv lub extruder tuag core tom qab tshem tawm qhov ruaj khov tuag. Lub siab extrusion ntawm cov ntaub ntawv sheath khaws cov qauv tubular ntawm cov yas coated aluminium daim kab xev, thiab qhov kub siab ntawm cov yas extruded softs cov yas txheej ntawm cov yas coated aluminium daim kab xev kom tiav cov kev sib txuas ua haujlwm. Cov tshuab no yog tsim rau ob sab laminated yas coated aluminium daim kab xev, cov cuab yeej siv tau yooj yim rau kev khiav lag luam, tab sis cov pwm ua yog qhov nyuaj, thiab cov yas coated aluminium daim kab xev yog yooj yim rau rebound.

Lwm cov txheej txheem kev sib txuas txias yog kev siv cov nplaum nplaum kub, kub yaj nplaum nplaum los ntawm lub tshuab extrusion nyob rau hauv longitudinal qhwv horn pwm txoj hauj lwm nyem rau ntawm ib sab ntawm sab ntug ntawm cov yas coated txhuas daim kab xev, ob ntug txoj hauj lwm ntawm cov yas. coated aluminium daim kab xev los ntawm cov kab ruaj khov thiab sizing tuag tom qab kub yaj nplaum nplaum. Cov tshuab no yog tsim rau ob qho tib si yas coated aluminium daim kab xev thiab ib sab yas coated txhuas daim kab xev. Nws cov pwm ua thiab cov cuab yeej tsim khoom yog yooj yim rau kev khiav lag luam, tab sis nws cov txiaj ntsig kev sib raug zoo cuam tshuam los ntawm qhov zoo ntawm cov nplaum nplaum kub.

Txhawm rau kom muaj kev ntseeg siab ntawm kev ua haujlwm ntawm cov kab hluav taws xob, cov ntaub thaiv npog hlau yuav tsum tau siv hluav taws xob txuas nrog lub rwb thaiv tsev ntawm cov kab hluav taws xob, yog li cov ntaub thaiv ib sab ntawm cov yas coated aluminium daim kab xev yuav tsum tau siv los ua cov hlau thaiv ntawm lub cable. Piv txwv li, cov txheej txheem kev sib khi kub uas tau hais hauv daim ntawv no tsuas yog tsim rau ob sabyas coated aluminium daim kab xev, thaum cov txheej txheem kev sib txuas txias siv cov nplaum nplaum kub yog qhov tsim nyog rau ib sab yas coated aluminium daim kab xev.
