Nyob rau hauv lub ntiaj teb niaj hnub no, hluav taws xob cables yog qhov tseem ceeb rau kev siv hluav taws xob hauv tsev, kev lag luam, thiab kev lag luam. Ntawm ntau hom cables siv, txiv kab ntxwv ncig cables tuav ib qho chaw tshwj xeeb vim lawv cov rwb thaiv tsev tshwj xeeb, uas ua haujlwm tshwj xeeb hauv kev ua kom muaj kev nyab xeeb, ua haujlwm zoo, thiab kev ntseeg tau. Ib qho ntawm cov lus nug feem ntau hais txog cov cables no yog, "Yuav ua li cas cov rwb thaiv tsev yog siv nyob rau hauv cov txiv kab ntxwv ncig cables?" Kab lus no yuav hais txog cov lus nug no kom ntxaws, thaum tseem tham txog cov ntawv pov thawj thiab cov qauv, xws li SAA daim ntawv pov thawj, Australia cov qauv, thiab AS/NZS 5000.1.
Cov kab kab kab kab kab kab kab kab ib feem ntau yog hais txog ib hom kev xaim hluav taws xob uas tsim los nrog ib puag ncig hla ntu thiab ib qho xim txiv kab ntxwv-xim txheej rwb thaiv tsev. Cov xim txiv kab ntxwv feem ntau siv rau hauv cov khoom siv hluav taws xob los qhia tias cov hlau yog tsim rau cov kev siv tshwj xeeb, tshwj xeeb tshaj yog cov uas muaj kev nyab xeeb siab, xws li hauv kev lag luam thiab sab nraum zoov ib puag ncig. Cov rwb thaiv tsev ntawm cov cables no ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov xaim los ntawm lwm yam thiab ua kom ntseeg tau tias kev xa hluav taws xob tau ua haujlwm zoo yam tsis muaj kev cuam tshuam lossis cuam tshuam.
Dab tsi yog hom rwb thaiv tsev siv?
Lub rwb thaiv tsev ntawm lub txiv kab ntxwv lub voj voog feem ntau yog tsim los ntawm cov ntaub ntawv uas muaj cov khoom siv hluav taws xob zoo, lub zog txhua yam, thiab tsis kam mus rau ntau yam ib puag ncig. Cov khoom siv feem ntau siv rau rwb thaiv tsev muaj xws li:
PVC (Polyvinyl Chloride):Qhov no yog ib qho ntawm feem ntau siv cov ntaub ntawv rwb thaiv tsev. PVC yog pheej yig, hloov tau, thiab muab kev tiv thaiv zoo rau cov dej noo, puas, thiab UV rays. Qhov no ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov hom phiaj dav dav.
XLPE (Cross-Linked Polyethylene):XLPE feem ntau yog siv rau hauv cov cables uas xav tau kev kub siab dua thiab ua haujlwm ntev. Nws muab kev ua tau zoo dua li cov txheej txheem PVC rwb thaiv tsev, tshwj xeeb tshaj yog nyob rau hauv kev xav tau ib puag ncig.
Rwb thaiv tsev:Roj hmab-raws li rwb thaiv tsev yog siv rau cables uas yuav tsum tau ntxiv yooj thiab tsis kam mus hnav thiab tsim kua muag. Cov khoom no kuj yog siv nyob rau hauv ib puag ncig uas cov cable raug rau cov roj, tshuaj, thiab kub heev.
LSZH (Low Smoke Zero Halogen):Rau cov ntawv thov uas muaj kev nyab xeeb hluav taws kub ntxhov, LSZH cov ntaub ntawv siv rau hauv rwb thaiv tsev. Cov ntaub ntawv no tso pa tawm tsawg kawg nkaus thiab tsis muaj roj halogen thaum kub hnyiab, ua rau lawv zoo tagnrho rau siv rau hauv cov chaw pej xeem, cov tsev lag luam, thiab lwm qhov chaw uas muaj kev nyab xeeb hluav taws yog qhov tseem ceeb.
Hom kev rwb thaiv tsev siv pes tsawg yuav nyob ntawm daim ntawv thov thiab cov kev cai tshwj xeeb ntawm cable. Piv txwv li, cov cables tsim los siv rau hauv chaw tsim khoom lossis sab nraum zoov feem ntau muaj cov rwb thaiv tsev zoo uas tuaj yeem tiv taus huab cua hnyav, kev puas tsuaj rau lub cev, thiab raug tshuaj lom neeg.
SAA Certificate thiab Australia Standards
Hauv tebchaws Australia, cov khoom siv hluav taws xob yuav tsum ua raws li cov qauv kev nyab xeeb nruj. Daim ntawv pov thawj SAA (Standards Australia Accredited) yog qhov qhia tau tias cov khoom tau raug kuaj thiab ua tau raws li cov qauv no. Thaum nws los txog rau cov khoom siv hluav taws xob, suav nrog cov txiv kab ntxwv ncig cov kab hluav taws xob, SAA daim ntawv pov thawj lees paub cov neeg siv khoom thiab kev lag luam tias cov cable tau tsim los rau cov qauv siab tshaj plaws thiab muaj kev nyab xeeb rau kev siv.
Daim ntawv pov thawj SAA feem ntau suav nrog kev nyab xeeb xws li:
Kev nyab xeeb hluav taws xob:Lub cable yuav tsum tsis txhob ua rau hluav taws xob poob los yog hluav taws kub nyob rau hauv ib txwm siv.
Durability:Lub cable yuav tsum tiv taus ib puag ncig yam xws li cua sov, av noo, thiab mechanical stress.
Ua raws li Australian cov cai:Lub cable yuav tsum ua raws li cov cai hauv zos thiab Australian Standards.
AS/NZS 5000.1 Standard
AS / NZS 5000.1 tus qauv yog ib qho ntawm cov qauv tseem ceeb hauv Australia thiab New Zealand rau cov khoom siv hluav taws xob. Cov qauv no qhia txog cov kev xav tau rau cov cables uas siv rau hauv kev teeb tsa ruaj khov hauv cov tsev. Nws npog ntau yam, suav nrog cov ntaub ntawv siv rau kev rwb thaiv tsev, qhov ntsuas kub ntawm cable, thiab nws tsis kam tiv thaiv hluav taws.
Rau ib lub txiv kab ntxwv lub voj voog kom tau raws li AS / NZS 5000.1 tus qauv, nws yuav tsum ua raws li cov hauv qab no:
Hom rwb thaiv tsev:Cov kab hluav taws xob rwb thaiv tsev yuav tsum yog tsim los ntawm cov khoom siv uas tuaj yeem tiv taus hluav taws xob thiab ib puag ncig kev ntxhov siab tam sim no nyob rau hauv ib puag ncig kev teeb tsa. Qhov no tuaj yeem txhais tau tias lub cable siv cov khoom siv xws li PVC, XLPE, lossis roj hmab, nyob ntawm daim ntawv thov.
Kev ntsuas kub:Lub cable yuav tsum muaj peev xwm ua haujlwm nyob rau hauv qhov ntsuas kub uas tau teev tseg. Rau feem ntau cov cables, qhov no txhais tau tias muaj peev xwm ua haujlwm zoo ntawm qhov kub txog 70 degree, tab sis qee cov cables yuav raug ntsuas rau qhov kub siab dua (xws li, 90 degree lossis 105 degree ).
Kev ntsuas hluav taws xob:Lub cable yuav tsum tau tsim los tswj cov qib voltage tshwj xeeb. Rau feem ntau cov txiv kab ntxwv kab uas siv rau hauv cov chaw nyob thiab kev lag luam, cov qauv ntsuas hluav taws xob feem ntau yog 450/750V lossis 0.6/1kV.
Hluav taws kub Resistance:Raws li AS / NZS 5000.1, cables kuj yuav tsum tau tsim los txo qhov kev pheej hmoo ntawm hluav taws kub thiab hluav taws xob. Qhov no suav nrog xyuas kom cov khoom siv rwb thaiv tsev tsis degrade lossis ntes hluav taws nyob rau hauv ib txwm muaj.
Cov kab hluav taws xob ua raws li AS / NZS 5000.1 tuaj yeem siv nyab xeeb rau ntau yam kev siv, suav nrog cov tsev nyob, kev lag luam, thiab kev lag luam, kom ntseeg tau tias lawv ua tau raws li cov qauv kev nyab xeeb uas yuav tsum tau muaj rau cov tshuab hluav taws xob hauv Australia thiab New Zealand.
Vim li cas Txiv Kab Ntxwv Circular Cables?
Txiv kab ntxwv ncig cables tshwj xeeb tshaj yog siv rau hauv kev lag luam thiab kev tsim kho, vim cov xim txiv kab ntxwv feem ntau cuam tshuam nrog kev nyab xeeb thiab pom kev zoo. Cov cables no feem ntau siv nyob rau hauv ib puag ncig uas kev nyab xeeb yog qhov tseem ceeb, xws li:
Kev Siv Hluav Taws Xob:Hauv cov chaw tsim khoom thiab cov khoom lag luam, qhov twg cov kab hluav taws xob yuav raug cuam tshuam rau cov neeg kho tshuab kev ntxhov siab, tshuaj lom neeg, lossis qhov kub thiab txias, cov kab txiv kab ntxwv ncig nrog cov rwb thaiv tsev zoo muab cov kev daws teeb meem zoo.
Sab nraum zoov Installations:Cov cables no feem ntau siv nyob rau hauv qhov chaw sab nraum zoov uas lawv raug tshav ntuj ncaj qha, los nag, thiab qhov kub thiab txias. Lub rwb thaiv tsev muab kev tiv thaiv tsim nyog los tswj kom muaj kev ncaj ncees ntawm lub cable.
Fais fab mov thiab Distribution:Txiv kab ntxwv ncig cov kab hluav taws xob siv rau hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob uas muaj cov hluav taws xob ntau dua lossis xav tau kev tiv thaiv ntxiv rau kev hnav thiab kev puas tsuaj ib puag ncig.
Kev nyab xeeb thiab kev txheeb xyuas:Cov xim txiv kab ntxwv nws tus kheej feem ntau yog siv los teeb tsa kev ceeb toom lossis cov xwm txheej tshwj xeeb. Yog li ntawd, cov xim txiv kab ntxwv ntawm lub cable ua rau nws yooj yim dua los txheeb xyuas thiab sib txawv ntawm lwm cov cables hauv kev teeb tsa nyuaj.
