Nyob rau xyoo tas los no, kev siv cov xov hluav taws kub tau nce ntxiv. Qhov kev nce ntxiv no yog vim cov neeg siv lees paub qhov ua tau zoo ntawm cov xov hluav taws kub no. Yog li ntawd, tus naj npawb ntawm cov chaw tsim khoom tsim cov xov hluav taws kub no kuj tau nce ntxiv. Kev ua kom ruaj khov thiab zoo ntawm cov xov hluav taws kub yog qhov tseem ceeb tshaj plaws.
Feem ntau, qee lub tuam txhab ua ntej tsim cov khoom siv hluav taws kub uas tiv taus hluav taws thiab xa mus rau cov koom haum tshawb nrhiav hauv tebchaws kom kuaj xyuas. Tom qab tau txais cov ntawv ceeb toom tshawb pom, lawv txuas ntxiv tsim ntau lawm. Txawm li cas los xij, ob peb lub tuam txhab tsim khoom siv hluav taws kub tau tsim lawv lub chaw soj ntsuam hluav taws kub. Kev sim hluav taws kub ua haujlwm ua kev tshuaj xyuas cov txiaj ntsig ntawm cov txheej txheem tsim khoom. Cov txheej txheem tsim khoom tib yam yuav ua rau cov cables muaj qhov sib txawv me ntsis ntawm lub sijhawm sib txawv. Rau cov tuam txhab tsim khoom siv hluav taws kub, yog tias qhov kev xeem dhau ntawm kev xeem hluav taws kub rau cov cables tiv taus hluav taws kub yog 99%, tseem muaj 1% kev phom sij rau kev nyab xeeb. Qhov kev pheej hmoo 1% no rau cov neeg siv txhais ua 100% kev phom sij. Txhawm rau daws cov teeb meem no, cov hauv qab no tham txog yuav ua li cas txhim kho qhov kev xeem dhau ntawm kev xeem hluav taws kub cables tiv taus hluav taws kub los ntawm cov yam xws licov khoom siv raw, kev xaiv tus neeg tsav tsheb, thiab kev tswj cov txheej txheem ntau lawm:
1. Siv Cov Tooj Liab Conductors
Qee cov chaw tsim khoom siv cov hlau tooj liab-clad txhuas ua cov tub ntxhais hlau cable. Txawm li cas los xij, rau cov cables tiv taus hluav taws, cov hlau tooj liab yuav tsum tau xaiv es tsis txhob siv cov hlau tooj liab-clad txhuas.
2. Kev nyiam rau Cov Conductors Puag Ncig Compact
Rau cov cores conductor voj voog nrog axial symmetry, covdaim kab xev micaCov xov hlau uas qhwv yuav nruj nreem rau txhua qhov kev taw qhia tom qab qhwv. Yog li ntawd, rau cov qauv ntawm cov xov hlau uas tiv taus hluav taws, nws yog qhov zoo dua los siv cov xov hlau me me puag ncig.
Cov laj thawj yog: Qee tus neeg siv nyiam cov qauv conductor nrog cov qauv mos mos, uas yuav tsum tau cov tuam txhab sib txuas lus nrog cov neeg siv txog kev hloov mus rau cov conductors puag ncig compact rau kev ntseeg tau hauv kev siv cable. Cov qauv mos mos lossis ob npaug twisting yooj yim ua rau puas tsuaj raudaim kab xev mica, ua rau nws tsis haum rau cov xov hlau uas tiv taus hluav taws. Txawm li cas los xij, qee lub tuam txhab tsim khoom ntseeg tias lawv yuav tsum ua tau raws li cov neeg siv xav tau rau cov xov hlau uas tiv taus hluav taws, yam tsis nkag siab tag nrho cov ntsiab lus tseem ceeb. Cov xov hlau muaj feem cuam tshuam nrog tib neeg lub neej, yog li cov tuam txhab tsim khoom xov hlau yuav tsum piav qhia meej txog cov teeb meem kev siv tshuab rau cov neeg siv.
Cov kiv cua zoo li tus kiv cua kuj tsis pom zoo vim tias qhov kev faib tawm ntawm lub siabdaim kab xev micaKev qhwv cov xov hlau uas zoo li kiv cua tsis sib npaug, ua rau lawv yooj yim khawb thiab sib tsoo, yog li ntawd txo qhov kev ua haujlwm hluav taws xob. Tsis tas li ntawd, los ntawm qhov kev xam pom ntawm tus nqi, qhov seem ntawm cov qauv xov hlau uas zoo li kiv cua loj dua li ntawm cov xov hlau puag ncig, ua rau kev siv cov kab xev mica kim dua. Txawm hais tias qhov txoj kab uas hla sab nraud ntawm cov xov hlau uas muaj cov qauv puag ncig nce ntxiv, thiab muaj kev siv cov khoom siv PVC ntau ntxiv, hais txog tus nqi tag nrho, cov xov hlau uas muaj cov qauv puag ncig tseem pheej yig dua. Yog li ntawd, raws li kev tshuaj xyuas saum toj no, los ntawm ob qho tib si kev siv tshuab thiab kev lag luam, kev siv cov xov hlau uas muaj cov qauv puag ncig yog qhov zoo dua rau cov xov hlau uas tiv taus hluav taws.
