ʻO ka inoa piha o ke kaula RVV he kaula palupalu i hoʻopaʻa ʻia me ka polyvinyl chloride insulated polyvinyl chloride sheathed flexible cable, i ʻike ʻia hoʻi ʻo ia ka uea palupalu i hoʻopaʻa ʻia me ka PVC māmā, i ʻike nui ʻia ʻo ka uea palupalu i hoʻopaʻa ʻia, he ʻano uea i hoʻopaʻa ʻia.
R: kū no ka laina palupalu/ʻano palupalu
V: Hoʻopaʻa PVC
V: ʻUpena PVC
ʻO ka inoa piha o ka laina uhi ʻia me ka ʻili keleawe BVV uwea PVC a me ka laina uhi poepoe PVC, i ʻike ʻia hoʻi ʻo ke kaula uhi PVC māmā, i ʻike nui ʻia ʻo ka laina uhi paʻakikī, he ʻano laina uhi.
ʻOkoʻa o ke ʻano:
ʻO ka laina BVV kahi uea keleawe hoʻokahi me kahi ʻāpana nui i loko, ʻoiai ʻo ka laina RVV kahi uea keleawe hoʻokahi me kahi ʻāpana liʻiliʻi i loko.
Eia kekahi laʻana, ʻelua mau ʻaʻahu he 2 x 1.5
ʻO ke kikowaena o loko o BVV he uea keleawe hoʻokahi. Loaʻa iā BVV ʻelua mau kikowaena o loko. ʻO ka ʻāpana kea o kēlā me kēia kikowaena o loko he 1.5 a ʻo kēlā me kēia kikowaena o loko he uea keleawe me ke anawaena o 1.38.
Ua haku ʻia ka ʻiwi kūloko RVV me nā filaments liʻiliʻi he nui, ʻo ka ʻiwi kūloko RVV2, ʻo ka ʻāpana kea o kēlā me kēia ʻiwi kūloko he 1.5, akā ua haku ʻia kēlā me kēia ʻiwi kūloko me 30 mau uea keleawe me ke anawaena o 0.25MM.
No laila ʻoi aku ka paʻakikī o BVV ma mua o RVV.
E hoʻohana i ka ʻokoʻa ma waena
Hoʻopili ʻia ʻo RVV i nā laina mana, nā laina hoʻomalu a me nā laina hoʻoili hōʻailona no nā mīkini uila, nā mika a me nā lako uila a me nā mea hoʻololi aunoa. Hiki ke hoʻohana ʻia no ka ʻōnaehana alarm anti-theft, ka ʻōnaehana intercom hale, nā mea kani, nā mea kani, ka nānā ʻana a me ka hoʻonohonoho ʻana i ka mana nānā, a pēlā aku.
He kūpono ke kaula ʻupena paʻakikī BVV no ka mea kanu mana, nā lako uila o ka hale, nā mea kani a me nā lako kelepona me ka uila AC a hiki i ka 450/750V. Hoʻohana ʻia nō hoʻi no nā uea hāmama.
