Thaum xaiv cov cables thiab cov xov hlau, qhia meej meej cov kev xav tau thiab tsom mus rau qhov zoo thiab cov lus qhia tshwj xeeb yog qhov tseem ceeb los ua kom muaj kev nyab xeeb thiab kav ntev. Ua ntej, qhov tsim nyog ntawm cable yuav tsum raug xaiv raws li kev siv scenario. Piv txwv li, kev xaim hluav taws xob hauv tsev feem ntau siv PVC (Polyvinyl Chloride) insulated cables, thaum muaj kev lag luam ib puag ncig, uas tej zaum yuav raug mob hnyav, feem ntau xav tau cov cables uas muaj kev tiv thaiv ntau dua rau cov cua sov thiab corrosion, xws li cov uas muajXLPE (Cross-Linked Polyethylene)rwb thaiv tsev. Rau kev siv sab nraum zoov, cables nrog Aluminium Foil Mylar Daim kab xev raws li cov ntaub thaiv npog yog nyiam los txhim kho huab cua tsis kam thiab kev ua haujlwm tsis zoo. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau kev xam cov load tam sim no thiab xaiv qhov tsim nyog cable specification raws li qhov ntsuas lub zog ntawm cov khoom siv hluav taws xob, kom ntseeg tau tias cov khoom siv hluav taws xob, xws li tooj liab tsis muaj oxygen lossis tinned tooj liab, muaj cov khoom siv txaus los tiv thaiv overheating lossis malfunction vim overload.
Hais txog cov khoom lag luam zoo, nws raug nquahu kom xaiv cov cables uas tau lees paub los ntawm cov koom haum xws li CCC thiab ISO 9001, kom ntseeg tau tias lawv ua tau raws li cov qauv hauv lub tebchaws. Tsis tas li ntawd, cov kab hluav taws xob zoo yuav tsum muaj qhov zoo nkauj, puag ncig nrog cov xim sib xws. Cov txheej rwb thaiv tsev yuav tsum tsis pub npuas los yog impurities thiab muaj cov tuab tuab. Raws li rau cov khoom siv conductor, tooj liab conductors yuav tsum yog xim liab-liab, nrog ib tug ci ntsa iab thiab nruj nreem twisted strands, thaum txhuas conductors yuav tsum yog silver-dawb. Yog hais tias tooj liab conductors tshwm liab-dub los yog muaj impurities, tej zaum lawv yuav ua los ntawm cov khoom tsis zoo, yog li yuav tsum tau ceev faj.
Thaum xaiv lub cable specification, tus neeg xyuas pib hla ntu yuav tsum tau txiav txim siab nyob rau hauv kev sib raug zoo nrog lub load tam sim no thiab qhov chaw ua hauj lwm. Ib tug loj tus neeg xyuas pib hla ntu tso cai rau muaj peev xwm nqa tam sim no ntau dua tab sis nce nqi. Yog li ntawd, kev sib npaug ntawm kev lag luam thiab kev nyab xeeb yog qhov tseem ceeb. Tsis tas li ntawd, tus naj npawb ntawm cov cores yuav tsum raug xaiv raws li qhov xav tau tiag tiag: ib-theem circuits feem ntau siv ob lossis peb-core cables, thaum peb-theem circuits xav tau peb lossis plaub-core cables. Los ntawm kev soj ntsuam kom zoo ntawm qhov kev siv scenario thiab cov kev cai, cov cables xaiv yuav yog ob qho tib si raug nqi thiab muaj peev xwm txhim khu kev lag luam mus sij hawm ntev.
Rau cov xwm txheej tshwj xeeb, xws li cov chaw kub kub, cov kab hluav taws xob kub-resistant, xws li hluav taws kub-resistant cables nrogmica daim kab xevwrapping los yog XLPE insulated cables, tuaj yeem tswj kev ua haujlwm ruaj khov hauv cov khoom siv hluav taws xob lossis cov chaw ua haujlwm kub. Rau cov tsev siab siab thiab cov chaw pej xeem uas muaj kev nyab xeeb hluav taws yog qhov tseem ceeb, hluav taws-tiv taus, nplaim hluav taws, lossis halogen-dawb nplaim hluav taws-retardant cables yog cov kev xaiv zoo dua. Cov kab hluav taws xob no feem ntau muaj cov txheej txheem hluav taws kub tshwj xeeb lossis suav nrog cov ntaub thaiv dej kom txo tau qhov hluav taws kub sib kis thiab txhim kho kev nyab xeeb.
Thaum kawg, xaiv lub npe nrov npe thiab tus neeg muag khoom ntseeg tau yog qhov tseem ceeb. Cov npe nrov npe feem ntau muaj cov txheej txheem tsim khoom nruj dua thiab kev tswj xyuas zoo, ua kom muaj kev ua tau zoo dua thiab muab kev pabcuam zoo tom qab muag. Kev yuav khoom los ntawm txoj cai raug cai, xws li kev lag luam khoom siv loj lossis cov neeg muag khoom muaj ntawv pov thawj, tsis tsuas yog lav qhov tseeb ntawm cov khoom, tab sis kuj ua kom muaj kev txhawb nqa raws sijhawm thaum muaj teeb meem. Nws raug nquahu kom tsis txhob yuav los ntawm qhov chaw tsis tau lees paub los tiv thaiv kev yuav khoom cuav lossis cov khoom tsis zoo.
Xaiv cov cables thiab xov hlau yog cov txheej txheem uas yuav tsum tau ua tib zoo saib ntawm txhua theem, los ntawm qhov yuav tsum tau ua thiab cov khoom siv rau cov khoom zoo thiab lub koob npe nrov ntawm tus neeg muag khoom. Kev xaiv kom raug tsis yog tsuas yog ua kom muaj kev nyab xeeb tab sis kuj tseem txhim kho lub neej kev pab cuam thiab kev ua haujlwm ntawm cov khoom.
