Hauv tebchaws Australia, qhov zoo thiab kev nyab xeeb ntawm cov xov hlau thiab cables yog ib qho tseem ceeb heev, tshwj xeeb tshaj yog nyob rau hauv cov khoom siv hluav taws xob hauv tsev thiab cov tsev lag luam. TPS cov xov hlau (thermoplastic sheathed cables) yog siv dav hauv Australia lub zog hluav taws xob vim lawv cov rwb thaiv tsev zoo heev, ua haujlwm ntev thiab tus nqi qis. 1.5 hli TPS xov hlau, 2.5 hli TPS xov hlau thiab 2.5 hli 2C E TPS xov hlau yog hom kev qhia tshwj xeeb. Hauv tebchaws Australia, tag nrho cov cables, suav nrog TPS cables, yuav tsum ua raws li cov qauv hauv tebchaws tshwj xeeb thiab dhau los ntawm cov txheej txheem ntawv pov thawj coj los ua kom lawv muaj kev nyab xeeb thiab ua haujlwm tau zoo. Tsab ntawv xov xwm no yuav ua kom tob tob rau hauv cov qauv thiab cov ntawv pov thawj rau TPS cov xov hlau hauv Australia los pab kom nkag siab tias hom hlau no ua tau raws li kev lag luam.
1. TPS hlau yog dab tsi?
TPS hlau (thermoplastic sheathed cable) yog ib hom kab hluav taws xob uas tau siv dav hauv cov khoom siv hluav taws xob hauv thaj chaw, kev lag luam thiab kev lag luam. TPS cable yog tsim los ntawm tooj liab conductors thiab thermoplastic PVC txheej sheaths, uas muaj zoo rwb thaiv tsev zog, tshav kub tsis kam, dej tsis kam thiab corrosion kuj. Nws sab nrauv tuaj yeem tiv thaiv kev puas tsuaj rau lub cev thiab tseem muaj kev ua tau zoo nyob rau hauv qhov chaw ntub dej.
TPS cables feem ntau muab faib ua ntau hom raws li tus naj npawb thiab ntu ntu ntawm cov neeg xyuas pib, xws li:
1.5 hli TPS cable:haum rau cov khoom siv hluav taws xob tsawg thiab cov teeb pom kev zoo.
2.5 hli TPS cable:haum rau cov khoom siv hluav taws xob nrog cov khoom siv tam sim no loj dua, xws li cov khoom siv hauv tsev thiab cov sockets.
2.5 hli 2C E TPS cable:ob-core cable, haum rau cov tshuab hluav taws xob hauv tsev uas xav tau ob-core txuas.
Cov kab hluav taws xob no tuav txoj haujlwm tseem ceeb hauv Australian tsev thiab kev lag luam hluav taws xob vim lawv txoj kev nyab xeeb, kev lag luam thiab kav ntev.
2. Australian cable qauv
Hauv tebchaws Australia, txhua yam khoom siv hluav taws xob, suav nrog cov xov hlau thiab cables, yuav tsum ua raws li cov qauv kev nyab xeeb. Cov qauv no yog tsim los ntawm Standards Australia thiab tau lees paub los ntawm Australian/New Zealand Hluav Taws Xob Standards (AS/NZS). Cov ntawv pov thawj no xyuas kom meej tias cov khoom siv cable ua tau raws li cov kev xav tau tshwj xeeb thiab ua kom muaj kev nyab xeeb thiab kev ntseeg siab hauv kev siv.
2.1 AS/NZS 3000: Hluav Taws Xob Cov Qauv
AS / NZS 3000 yog tus qauv kev teeb tsa hluav taws xob rau Australia thiab New Zealand, uas qhia txog kev nyab xeeb rau txhua cov xov hlau thiab cables hauv cov tshuab hluav taws xob. Rau TPS cov xov hlau, tshwj xeeb tshaj yog 1.5 hli TPS cables, 2.5 hli TPS cables, thiab 2.5 hli 2C E TPS cables, muaj ntau yam tseem ceeb uas yuav tsum tau ua raws li:

Hluav taws kub tsis kam:Sab nrauv ntawm lub cable yuav tsum muaj qee yam hluav taws kub tiv thaiv kom tsis txhob muaj hluav taws kub kub sai sai thaum muaj hluav taws kub. Txawm hais tias lub plhaub sab nraud ntawm TPS hlau yog PVC, nws tseem yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom muaj hluav taws kub hnyiab kom ntseeg tau tias cov khoom siv hluav taws xob tuaj yeem txo qhov kev pheej hmoo ntawm hluav taws kub thaum muaj xwm txheej.
Dej tsis kam:Cov cables yuav tsum muaj cov khoom tsis muaj dej, tshwj xeeb tshaj yog thaum lawv tau nruab rau hauv qhov chaw ntub lossis sab nraum zoov. Tsim nyog TPS cov xov hlau tuaj yeem tiv thaiv cov dej noo los ntawm kev nkag mus rau sab hauv, yog li tsis txhob muaj hluav taws xob tsis ua haujlwm.
Mechanical zog:Sab nrauv ntawm lub cable yuav tsum muaj lub zog txhua yam txaus los tiv thaiv kev puas tsuaj ntawm lub cev, suav nrog kev sib tsoo, khoov, thiab ncab.
2.2 AS/NZS 5000:Cable tsim thiab specifications
Hauv Australia, AS / NZS 5000 qhia txog cov qauv tsim rau ntau hom cables, npog cov khoom siv cable sab nrauv, cov khoom siv hluav taws xob, cov khoom nqa tam sim no thiab lwm yam. Rau TPS cov xov hlau, cov qauv tseem ceeb suav nrog:
Cov khoom siv conductor:Tus neeg xyuas pib yuav tsum siv cov khoom siv tooj liab uas ua tau raws li cov kev cai kom ntseeg tau tias muaj hluav taws xob zoo.
Sheath khoom:Cov khoom siv hluav taws xob sab nrauv yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm PVC (polyvinyl chloride), thiab cov ntaub qhwv sab nrauv yuav tsum muaj cov cua sov zoo, tiv thaiv corrosion thiab huab cua tsis kam, thiab tuaj yeem tiv taus lub hnub ci thiab qhov chaw ntub dej.
Marking xav tau:Lub cable sab nrauv sheath yuav tsum tau cim nrog cov ntaub ntawv xws li qauv, specification, chaw tsim tshuaj paus thiab tus qauv tooj los xyuas kom meej cov khoom traceability thiab ua raws li.
2.3 AS/NZS 1125:Cov kev xav tau ntawm kev ua haujlwm rau cables
AS / NZS 1125 yog tus qauv rau kev ua haujlwm ntawm cov ntaub ntawv cable, suav nrog cov kev xav tau ntawm rwb thaiv tsev, conductors thiab sheaths. TPS cables yuav tsum ua kom tau raws li cov hauv qab no cov cim qhia ua haujlwm tseem ceeb:
Kub kam rau ua:Lub rwb thaiv tsev thiab sheath ntawm lub cable yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig, feem ntau xav tau lub cable kom tiv taus qhov kub ntawm yam tsawg 70 degree.
Kev laus kuj:Lub cable yuav tsum muaj zog UV tiv thaiv thiab kev laus tiv thaiv kom ntseeg tau tias nws yuav tsis deteriorate vim ib puag ncig hloov tom qab siv mus ntev.
3. TPS cable ntawv pov thawj thiab kev tswj kom zoo
Hauv Australia, daim ntawv pov thawj ntawm TPS cov xov hlau thiab lwm cov cables yuav tsum ua raws li cov qauv tsim nyog thiab raug kuaj thiab pom zoo los ntawm lub cev ntawv pov thawj. Cov ntawv pov thawj uas muaj xws li:
SAA daim ntawv pov thawj:Tshaj tawm los ntawm Standards Australia, nws qhia tau hais tias lub cable ua raws li AS / NZS cov qauv. Daim ntawv pov thawj no ua kom ntseeg tau tias lub cable yuav tsis poob thaum siv thiab ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb hauv kev tsim thiab cov khoom siv.
Australian Certification Mark (ACM): Qhov no yog ib daim ntawv pov thawj uas siv dav heev uas qhia tau hais tias lub cable ua raws li tag nrho Australian cov qauv kev nyab xeeb hluav taws xob thiab tau dhau qhov kev ntsuam xyuas zoo.
CE cim:Rau TPS cables xa tawm mus rau European Union, daim ntawv pov thawj CE yog qhov yuav tsum tau ua, qhia tias cov khoom ua tau raws li kev noj qab haus huv, kev nyab xeeb thiab ib puag ncig ntawm European kev ua lag luam.
Hauv tebchaws Australia, cov tuam txhab tsim khoom yuav tsum dhau los ntawm cov txheej txheem tswj xyuas nruj kom ntseeg tau tias lawv cov khoom ua tau raws li cov qauv kev cai. Txhua pawg ntawm cov khoom siv cable yuav raug kuaj nqa tam sim no, kev ntsuas hluav taws kub, kev ntsuas lub zog, thiab lwm yam kom ntseeg tau tias lawv siv tau ntev.
4. Daim ntawv pov thawj yuav tsum tau rau TPS cables ntawm txawv specifications
Txawm hais tias qhov tshwj xeeb ntawm 1.5 hli TPS cov xov hlau, 2.5 hli TPS cov xov hlau thiab 2.5 hli 2C E TPS cov xov hlau sib txawv, lawv txhua tus yuav tsum ua kom tau raws li cov qauv saum toj no thiab cov ntawv pov thawj. Nov yog qee qhov kev txiav txim siab rau lawv cov ntawv thov tshwj xeeb:
4.1 1.5 hli TPS xov hlau
1.5 hli TPS xov hlau yog tsuas yog siv rau cov khoom siv hluav taws xob qis thiab teeb pom kev zoo. Vim lawv qhov me me hla ntu thiab lub peev xwm nqa tam sim no, cov cable no feem ntau yog siv rau hauv cov ntawv thov hluav taws xob yooj yim dua thiab muaj kev nyab xeeb dua, xav tau cov kab hluav taws xob kom muaj hluav taws xob yooj yim, kev ua haujlwm rwb thaiv tsev thiab lub zog txhua yam.
4.2 2.5 hli TPS xov hlau
2.5 hli TPS cov xov hlau yog tsim rau cov khoom siv hluav taws xob ntau dua thiab cov khoom siv hluav taws xob. Vim qhov yuav tsum tau nqa cov khoom siv hluav taws xob ntau dua, cov qauv tsim thiab cov kev xav tau zoo ntawm cov cable no yog qhov nruj dua. Ntxiv nrog rau cov qauv siv hluav taws xob, cov tuam ntxhab yuav tsum xyuas kom meej tias cov ntaub ntawv rwb thaiv tsev ntawm lawv cov cables muaj kev laus zoo thiab kub tsis kam.
4.3 2.5 hli 2C E TPS hlau
2.5 hli 2C E TPS hlau yog siv nyob rau hauv ob-core hluav taws xob tshuab, feem ntau yog rau cov qhov (socket) thiab cov khoom siv hauv tsev. Cov cable no yuav tsum tau mus dhau cov txheej txheem ntawv pov thawj ntxiv kom ntseeg tau tias ob lub tshuab hluav taws xob muaj hluav taws xob ruaj khov, kev rwb thaiv tsev zoo, thiab tuaj yeem ua haujlwm tau ntev hauv qhov chaw ntub dej lossis hnyav.
