Copper core polyvinyl chloride insulated wire (BVR), bv xaim yog hom xaim, qhov twg b txhais tau tias cov ntaub hlau, V txhais tau tias cov khoom rwb thaiv tsev ntawm cov hlau yog polyvinyl chloride (tseem hu ua PVC), r txhais tau tias cov hlau mos. Lub npe tag nrho yog tooj liab tub ntxhais polyvinyl chloride insulated daim ntaub hlau, bvr hlau neeg xyuas pib yog ib tug ntau-strand ntawm mos tooj liab hlau twisted thiab tsim, cov hlau nws tus kheej yog mos, yuav khoov mus rau siv, thaiv lub kaum sab xis loj dua, kev siv ntawm tus qauv. (JB8734-2012) faib txee tshwj xeeb mos xaim, uas yog siv nyob rau hauv kev ruaj ntseg yuav tsum tau mos mos zaus. Yuav siv tau rau tsev kho kom zoo nkauj teeb pom kev zoo, ntsuas voltage 450-750V. Nws tuaj yeem siv los ua cov xaim hauv av, qhov tso cua sov tsis tsawg dua 0 degrees, qhov kub ua haujlwm tsis tshaj 70 degrees, tsim nyog rau kev xaim hauv tsev thiab hauv av xaim, txhawm rau pab txhawb qhov sib txawv ntawm txheej txheem installation, cov grams yog liab, daj, xiav, ntsuab, dub, dawb, ob npaug rau xya xim. Vim tias BVR yog cov qauv muag muag, cov peev txheej ntawm daim ntawv thov kuj yog feem ntau hauv ib puag ncig muag. Haum rau thaj chaw nyob, thaj chaw tseem ceeb ntawm cov khoom siv hluav taws xob siv hluav taws xob, peb cov ntawv thov xaim yog qhov dav, cov hlua ruaj ruaj tuaj yeem siv rau sab hauv daim ntawv thov, yeeb nkab thiab lwm yam, txais tos sab laj.
