KA HANA A ME NĀ ʻANO O KE KAUWAE YJV

ʻO ke kaula YJV kahi ʻano kaula mana i hoʻohana nui ʻia. I kēia mau lā, nui ka poʻe e kapa ana i ke kaula YJV i ka wā e kamaʻilio ai e pili ana i ke kaula. Ma ke ʻano he kaula iwi kuamoʻo i ka hoʻoili mana, ua like ke kaula YJV me nā kīʻaha koko arterial i loko o nā kīʻaha koko kanaka, a i ʻole ke kumu o kahi lāʻau, e hōʻike ana i kona kūlana koʻikoʻi i ka hoʻoili mana. Loaʻa pinepine nā kaula YJV ma nā alahele kūlanakauhale ma lalo o ka honua (ma lalo o nā uhi manhole) a i kanu ʻia paha ma lalo o ka honua. I ka manawa pinepine, ʻoki nā hui kūkulu i nā kaula mana i ka wā o ke kūkulu ʻana, e hopena ana i nā pio mana nui, ʻo ia hoʻi nā kaula mana.

ʻO ka inoa piha o YJV: uwea mana XLPE insulated PVC, YJ-XLPE insulated, V-PVC sheathed, hoʻohana nui ʻia ma ke ʻano he kaula iwi kuamoʻo. ʻO nā hiʻohiʻona maʻamau e komo pū me ke kaula YJV maʻamau, ke kaula YJV22 i uhi ʻia me ka lipine kila, ke kaula lapalapa ZR-YJV, ke kaula pale ahi NH-YJV, a me ke kaula halogen haʻahaʻa-uahi WDZ-YJV. ʻO nā voltages i hoʻohana pinepine ʻia o nā kaula YJV he 0.6/1kv a me 8.5/15kv. ʻO ka helu o nā cores uwea i hoʻohana pinepine ʻia he ʻelua cores, ʻekolu cores, ʻehā cores, ʻelima cores, 3+1 cores, 3+2 cores, a me 4+1 cores. Ma lalo o nā kūlana maʻamau, hoʻohana nui ʻia he 3 cores no ke voltages kiʻekiʻe, ʻoi aku ke kiʻekiʻe o ke kumukūʻai, a ʻoi aku ka pinepine o nā loli o ke kumukūʻai.

Loaʻa i ke kaula mana XLPE insulated nā waiwai thermal-mechanical maikaʻi loa, nā waiwai uila maikaʻi loa a me ke kūpaʻa i ka corrosion kemika, a he mau pono nō hoʻi o ke ʻano maʻalahi, ke kaumaha māmā, a ʻaʻole i kaupalena ʻia e ka hāʻule ʻana o ke kau ʻana. Hoʻohana nui ʻia ia i nā pūnaewele mana kūlanakauhale, nā mines a me nā kaula Novel mai ka hale hana.
