Dab tsi raws nraim cov cim cim ntawm cov xov hluav taws xob sawv cev?
BV Hlau: "B" sawv cev rau "txhim hluav taws xob", thaum "V" qhia tias muaj txheej txheej insulating. Tus naj npawb ntawm "V" sib raug rau tus naj npawb ntawm cov ntaub qhwv sab nrauv tam sim no. BV hlau yog ib qho -strand khoom hlau, feem ntau yog siv nyob rau hauv tej yaam num kho tsev.
BVR Wire: "R" sawv cev rau "ntau-strand tooj liab hloov tau yooj yim" (lossis tsuas yog "hloov hlau"). Rau ib tug muab xaim gauge, ntau dua tus naj npawb ntawm ib tug neeg tooj liab strands, qhov hloov tau yooj yim cov hlau yuav. BVR hlau yog tsim rau cov ntawv thov uas yuav tsum tau yooj yim.
RV Hlau: Qhov kev xaiv no nta ob "V", qhia tias nws muaj ob txheej ntawm rwb thaiv tsev. RV hlau muaj ntau tus neeg tooj liab strands ntau dua li tus qauv RV hlau, ua rau nws haum rau cov xwm txheej xav tau ntau dua.
RVV Hlau: Qhov no yog hais txog qhov hloov tau yooj yim, ntau- tub ntxhais cable; tus **TRVV** variant, tshwj xeeb tshaj yog, txhais tau hais tias ib qho ultra- hloov tau ntau- tub ntxhais cable. Lub "TR" ua ntej txhais tau hais tias "ultra- hloov tau," thaum ob "V" rov qhia ob txheej ntawm rwb thaiv tsev. Hom xov hlau no siv cov xov tooj zoo dua, suav nrog cov txheej txheem tsim khoom ntau dua, thiab yog li nqa tus nqi siab dua.
Los ntawm kev nkag siab txog cov cim ntawm cov hlau no, koj tuaj yeem ua tau zoo dua -txoj kev xaiv los xaiv cov cables uas zoo tshaj plaws rau koj cov kev xav tau tshwj xeeb, yog li ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm koj cov khoom siv hluav taws xob.
