Hauv tebchaws Australia, nrog rau kev siv ntau ntxiv ntawm kev tsim kho kev lag luam thiab cov khoom siv hluav taws xob hauv tsev, TPS hlau (thermoplastic sheathed cable) tau dav siv hauv tsev, kev lag luam thiab chaw ua lag luam raws li lub ntsiab hluav taws xob xaim xaim. TPS cable yog dav siv vim nws zoo heev kub tsis kam, corrosion kuj thiab yooj, tab sis tseem muaj substandard cable khoom nyob rau hauv lub lag luam, uas tej zaum yuav ua rau hluav taws xob hluav taws xob, hluav taws xob tsis ua hauj lwm thiab hluav taws xob raug mob. Yog li ntawd, nws yog ib qho tseem ceeb heev los txheeb xyuas TPS cov xov hlau tsis zoo thiab xyuas kom lawv ua tau raws li cov qauv tsim nyog thiab cov kev cai nyab xeeb.
Tsab ntawv xov xwm no yuav qhia txog yuav ua li cas txheeb xyuas qhov tsis zoo 1.5 hli TPS cables, TPS 2.5 hli thiab 2.5 hli 2C E TPS cables, thiab muab cov txheej txheem tshawb nrhiav thiab cov lus qhia tshwj xeeb.
1. Nkag siab txog cov qauv thiab cov ntawv pov thawj ntawm TPS cov xov hlau uas tsim nyog
Hauv tebchaws Australia, txhua yam khoom siv hlau yuav tsum ua tau raws li cov qauv hauv lub tebchaws thiab cov ntawv pov thawj kom ntseeg tau tias lawv muaj kev nyab xeeb thiab kev ntseeg siab thaum siv. Rau TPS cov xov hlau, cov qauv ntawv pov thawj muaj xws li:
AS/NZS 5000.1:Qhov no yog tus qauv cable rau Australia thiab New Zealand, uas qhia txog cov kev xav tau ntawm kev ua haujlwm, kev sim thiab kev txheeb xyuas cov kev xav tau ntawm cov xov hlau.
SAA daim ntawv pov thawj:Qhia tau tias lub cable ua raws li Australian cov qauv thiab tau ua tiav kev sim ua kom zoo.
C-Tick daim ntawv pov thawj:Xyuas kom cov hlau ua tau raws li qhov yuav tsum tau ua ntawm electromagnetic compatibility.
Tsim nyog 1.5 hli TPS cables, TPS 2.5 hli thiab 2.5 hli 2C E TPS cables yuav tsum tau cim nrog cov ntawv pov thawj thiab cov qauv saum toj no, txwv tsis pub koj yuav tsum tau ceev faj tshwj xeeb.
2. Cov txheej txheem ntau los txheeb xyuas TPS cov xov hlau tsis tsim nyog
2.1 Txheeb xyuas qhov pom ntawm lub cable
Cov tsos ntawm cov cable yog qhov tseem ceeb hauv kev txiav txim siab zoo ntawm cov hlau. Tsim nyog TPS cables yuav tsum muaj qhov sib xws, qhov chaw du, thiab tsis muaj qhov tsis xws luag lossis kev puas tsuaj.
Cov yam ntxwv ntawm cov kab tsis tsim nyog: Cov kab tsis tsim nyog feem ntau muaj teeb meem hauv qab no:
Deg tawg los yog dents:Yog hais tias lub sab nraud ntawm lub cable muaj cov kab nrib pleb los yog dents, nws yuav qhia tau hais tias cov khoom siv tsis zoo tau siv rau hauv cov txheej txheem tsim khoom lossis nws puas raug puas tsuaj thaum thauj thiab khaws cia.
Discoloration los yog softening ntawm sheath:Kev tsim nyog cable sheaths yuav tsum tswj lawv cov cua sov thiab UV tiv thaiv cov khoom thaum raug tshav ntuj los yog kub ntev ntev. Yog hais tias lub tsho yuav muag muag, tsis muaj xim, los yog nkig, nws yuav yog vim lub cable tsis ua raws li cov qauv los yog siv cov khoom tsis zoo.
Kev rwb thaiv tsev tsis sib xws:Lub rwb thaiv tsev txheej ntawm lub cable yuav tsum tau muab sib npaug. Yog tias muaj qhov tsis sib xws, nws tuaj yeem ua rau tam sim no to lossis overheating, ua rau muaj kev pheej hmoo ntawm hluav taws.
2.2 Txheeb xyuas cov cim kab ntawv
Tsim nyog TPS cables feem ntau qhia txog cov chaw tsim khoom, cov khoom tshwj xeeb, cov ntawv pov thawj, thiab cov qauv uas lawv ua tau raws. Piv txwv li, lub cable yuav tsum tau cim nrog lub logo zoo ib yam li cov hauv qab no:
Cov qauv khoom (xws li 1.5 hli TPS cable, TPS 2.5 hli, 2.5 hli 2C E TPS cable).
Lub peev xwm nqa tam sim no thiab kev ua haujlwm kub ntau.
Daim ntawv pov thawj ua raws (xws li SAA daim ntawv pov thawj, C-Tick certification, thiab lwm yam).
Hnub tsim khoom thiab batch naj npawb.
Yog tias tsis muaj kev txheeb xyuas ntawm lub cable, lossis qhov kev qhia tsis meej, nws yuav qhia tau tias lub cable tsis tsim nyog thiab yuav tsum tau zam.
2.3 Ntsuas cov conductivity thiab tam sim no nqa peev xwm ntawm lub cable
Thaum tam sim no dhau los ntawm kev tsim nyog TPS cable, tus neeg xyuas pib yuav tsum muaj peev xwm ua tau zoo tam sim no yam tsis muaj cua sov, tsis zoo, lossis tsis ruaj khov tam sim no.
Cov conductivity tsis zoo:Cov kab hluav taws xob tsis tsim nyog yuav siv cov tooj liab tsis zoo lossis cov xaim txhuas, uas tuaj yeem ua rau tam sim no tsis tuaj yeem ua haujlwm zoo. Lub conductivity ntawm cable yuav raug kuaj los ntawm cov kws tshaj lij hluav taws xob kuaj ntsuas. Yog tias qhov kev ntsuam xyuas tau pom tias qhov kev tiv thaiv ntawm cable yog siab dua li tus qauv ib txwm, nws txhais tau hais tias lub cable yuav tsis zoo.
Lub peev xwm nqa tam sim no tsis txaus:Cov kab tsim nyog muaj peev xwm nqa tau tam sim no, xws li 1.5 hli TPS cables feem ntau tuaj yeem nqa tau 10-13 amperes ntawm tam sim no, 2.5 hli TPS cables tuaj yeem nqa tau 16-20 amperes ntawm tam sim no, thiab 2.5 hli 2C E TPS cables tau kuj txhawb cov dej ntws zoo sib xws. Yog tias lub cable tsis tuaj yeem nqa nws lub npe tam sim no, nws txhais tau hais tias qhov zoo ntawm cable yog teeb meem.
2.4 Kev ntsuas kub ua haujlwm siab
Cov ntaub ntawv sheath ntawm TPS cable yuav tsum muaj qee qhov kub tsis kam. Australia cov xwm txheej huab cua yog qhov hnyav heev, tshwj xeeb tshaj yog nyob rau lub caij ntuj sov, thaum lub tshuab hluav taws xob hnyav hnyav thiab cov kab hluav taws xob yuav ntsib qhov kub siab dua. Tsim nyog TPS cables yuav tsum muaj peev xwm tiv taus qee qhov kub thiab txias.
Kev ua tau zoo ntawm cov kab tsis tsim nyog:Yog hais tias cov ntaub ntawv sheath ntawm lub cable softens, deforms, los yog ntog ntawm qhov kub thiab txias, nws txhais tau hais tias lub cable tsis muaj cua sov tsis kam thiab tej zaum yuav siv cov khoom tsis zoo, uas yuav ua rau muaj kev nyab xeeb.
2.5 Tiv thaiv qhov ntsuas hluav taws xob
TPS cables feem ntau yuav tsum tau tiv taus ib qho hluav taws xob. Yog tias cov txheej txheem rwb thaiv tsev ntawm lub cable tsis tsim nyog, nws yuav ua rau muaj kev cuam tshuam tam sim no thiab luv luv.
Kev ua tau zoo ntawm cov kab tsis tsim nyog:Cov kab hluav taws xob tsis tsim nyog yuav muaj cov rwb thaiv tsev tsis zoo, uas tuaj yeem yooj yim ua rau luv luv lossis hluav taws xob poob qis hauv cov xwm txheej siab. Lub cable tuaj yeem kuaj nrog lub ntsuas hluav taws xob los xyuas kom meej tias cov rwb thaiv tsev ntawm lub cable ua tau raws li cov qauv.
3. Ceev faj thaum siv cov cables
Thaum txhim kho lossis siv cov cables, cov ntsiab lus hauv qab no tuaj yeem pab kom tsis txhob muaj kev nyab xeeb los ntawm kev siv cov cables tsis tsim nyog:
3.1 Tsis txhob siv cov cables uas tsis tau lees paub
Tsuas yog yuav cov cables nrog cov ntawv pov thawj meej (xws li SAA daim ntawv pov thawj thiab C-Tick certification) kom ntseeg tau tias lawv ua tau raws li Australian cov qauv kev nyab xeeb thiab muaj kev ruaj ntseg zoo.
3.2 Ua tib zoo saib xyuas cov lus qhia tshwj xeeb ntawm lub cable
Xaiv cov kab hluav taws xob uas tsim nyog raws li lub zog xav tau ntawm cov khoom siv hluav taws xob. Piv txwv li, 1.5 hli TPS cables yog tsim rau cov khoom siv hluav taws xob tsawg, thaum 2.5 hli TPS cables yog tsim rau nruab nrab thiab siab zog. Yog tias koj tsis paub meej tias lub cable puas tsim nyog, nws raug nquahu kom xaiv lub cable loj dua los txhim kho kev nyab xeeb.
3.3 Txheeb xyuas qhov xwm txheej ntawm lub cable tsis tu ncua
Thaum siv cov cable, teeb meem yuav tshwm sim vim kev laus, hnav thiab tsim kua muag. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tsis tu ncua xyuas cov tsos, rwb thaiv tsev txheej thiab tus neeg xyuas pib mob ntawm lub cable, thiab hloov cov laus cable nyob rau hauv lub sij hawm kom tsis txhob muaj tej yam hluav taws xob tsis ua hauj lwm.
3.4 Tsis txhob overload cable
Overload yog ib qho ua rau muaj hluav taws xob sib tsoo. Thaum siv lub cable, tsis txhob tshaj nws qhov siab tshaj plaws tam sim no nqa lub peev xwm los tiv thaiv lub cable los ntawm overheating, melting los yog ua rau hluav taws.
