R: inomirira mutsetse wakapfava/chimiro chakapfava
V: PVC insulation
V: PVC sheath
Zita rakazara reBVV cable copper core PVC insulated uye PVC sheathed round sheathed line, inozivikanwawo seLight PVC sheathed cable, inowanzozivikanwa se hard sheathed line, imhando ye sheathed line.
Musiyano wechimiro:
Mutsetse weBVV iwaya imwe chete yemhangura ine chikamu chikuru mukati, nepo mutsetse weRVV iri waya imwe chete yemhangura ine chikamu chidiki mukati.
Semuenzaniso, ese ari maviri majaketi ane 1.5 x 2 x 1.5
Pakati peBVV iwaya imwe chete yemhangura. BVV ine macore maviri emukati. Chikamu chepakati pepakati pega pega i1.5 uye pakati pepakati pega pega iwaya yemhangura ine dhayamita ye1.38
Muviri wemukati weRVV unoumbwa neshinda diki dzakawanda, mutsetse wemukati weRVV2, chikamu chepakati chega chega chemukati i1.5, asi mutsetse wega wega wemukati unoumbwa newaya dzemhangura makumi matatu dzine dhayamita ye0.25MM.
Saka BVV yakaoma kupfuura RVV.

RVV inoshandiswa patambo dzemagetsi, tambo dzekudzora uye tambo dzekutumira masaini emidziyo yemagetsi, mita nemidziyo yemagetsi pamwe nemidziyo yekutsiva otomatiki. Inogona kushandiswa pakuchengetedza alarm system yekudzivirira kuba, building intercom system, mudziyo, mudziyo, kuisa kudzora kwekutarisa nekutarisa, nezvimwewo.
Waya yeBVV hard sheath yakakodzera magetsi, midziyo yemagetsi yemumba, zvishandiso zvemagetsi uye zvekutaurirana zvine AC voltage inosvika uye inosanganisira 450/750V. Inoshandiswawo pakuisa waya dzakavhurika.
