Lub npe tag nrho ntawm RVV cable yog lub teeb tooj liab tub ntxhais polyvinyl chloride insulated polyvinyl chloride sheathed flexible cable, tseem hu ua lub teeb PVC sheathed flexible wire, feem ntau hu ua mos sheathed wire, yog ib hom sheathed wire.
R: sawv cev rau kab mos / qauv mos

Lub npe tag nrho ntawm BVV cable tooj liab tub ntxhais PVC rwb thaiv tsev thiab PVC sheathed puag ncig sheathed kab, tseem hu ua lub teeb PVC sheathed cable, feem ntau hu ua nyuaj sheathed kab, yog ib hom kab sheathed.
Qhov sib txawv ntawm cov qauv:
Kab BVV yog ib txoj hlau tooj liab uas muaj ib ntu loj dua sab hauv, thaum kab RVV yog ib txoj hlau tooj liab uas muaj ib ntu me dua sab hauv.
Piv txwv li, ob qho tib si yog 2 x 1.5 lub tsho loj
Lub plawv sab hauv ntawm BVV yog ib txoj hlau tooj liab xwb. BVV muaj ob lub plawv sab hauv. Qhov seem ntawm txhua lub plawv sab hauv yog 1.5 thiab txhua lub plawv sab hauv yog ib txoj hlau tooj liab uas muaj txoj kab uas hla ntawm 1.38.
RVV sab hauv lub plawv yog tsim los ntawm ntau cov filaments me me, RVV2 sab hauv lub plawv, qhov seem ntawm txhua lub plawv sab hauv yog 1.5, tab sis txhua lub plawv sab hauv yog tsim los ntawm 30 tooj liab xov hlau nrog lub cheeb ntawm 0.25MM.
Yog li ntawd, BVV nyuaj dua li RVV.
Siv qhov sib txawv ntawm
RVV siv rau cov kab hluav taws xob, cov kab tswj thiab cov kab xa xov rau cov khoom siv hluav taws xob, cov 'meter' thiab cov khoom siv hluav taws xob thiab cov khoom siv hloov pauv tsis siv neeg. Nws tuaj yeem siv rau lub tswb ceeb toom tiv thaiv kev tub sab, lub tsev intercom system, twj paj nruag, twj paj nruag, kev saib xyuas thiab kev tswj xyuas kev teeb tsa, thiab lwm yam.
BVV cov xov hlau tawv yog tsim rau cov chaw tsim hluav taws xob, cov khoom siv hluav taws xob hauv tsev, cov cuab yeej siv thiab cov khoom siv sib txuas lus nrog AC voltage txog li 450/750V. Nws kuj tseem siv rau kev qhib xov hlau.
