1.Nā hale kiaʻi hoʻouname nā pae uila o 110kV a ma luna

I loko o kēia laina uila, ʻo ka hapa nui o nā laina he 5 conductors. Ua kapa ʻia nā mea hoʻokele ʻelua ma luna o nā uea pale, ʻike ʻia hoʻi ʻo nā uwea pale uila. ʻO ka hana nui o kēia mau uea ʻelua, ʻo ia ka pale ʻana i ka mea alakaʻi mai ka paʻi pololei ʻana e ka uila.

ʻO nā mea hoʻokele haʻahaʻa ʻekolu, ʻo ia nā mea alakaʻi A, B, a me C, i kapa ʻia ʻo ka mana ʻekolu-phase. Hiki ke ʻokoʻa ka hoʻonohonoho ʻana o kēia mau alakaʻi ʻekolu ma muli o ke ʻano hale kiaʻi. Ma kahi hoʻonohonoho hoʻonohonoho ʻana, aia nā mea hoʻokele ʻekolu ʻāpana i ka mokulele hoʻokahi. No nā laina kaapuni hoʻokahi, aia kekahi hoʻonohonoho ākea i ke ʻano o ka huapalapala "H". No nā laina kaapuni ʻelua a i ʻole nā ​​laina kaapuni nui, ʻae ʻia ka hoʻonohonoho kū pololei. He mea pono e hoʻomaopopo i kekahi mau laina 110kV i hoʻokahi wale nō uea pale, e loaʻa ana i 4 mau alakaʻi: 1 uea pale a me 3 mau alakaʻi.

monopole hoʻoili

2.35kV-66kV Voltage Level Transition Tower

ʻO ka hapa nui o nā laina ma luna o kēia ʻāpana he 4 mau alakaʻi, a ʻo ka mea ma luna e pale mau ʻia a ʻo ka lalo ʻekolu he mau alakaʻi.

kia uila

3.10kV-20kV Voltage Level Transition Tower

ʻO ka hapa nui o nā laina ma luna o kēia ʻano he 3 mau alakaʻi, nā mea alakaʻi āpau āpau, ʻaʻohe pale. Pili kēia i nā laina hoʻouna kaapuni hoʻokahi. I kēia manawa, ʻo nā laina 10kV ma nā wahi he nui nā laina hoʻouna kaapuni. No ka laʻana, ʻo ka laina kaapuni pālua he 6 mau alakaʻi, a ʻo kahi laina ʻehā he 12 mau alakaʻi.

4.Low-voltage overhead line transmission tower (220V, 380V)

Inā ʻike ʻoe i kahi laina ma luna me ʻelua mau alakaʻi ma luna o kahi pou kaila haʻahaʻa a me kahi mamao ma waena o lākou, ʻo ia ka laina 220V. He kakaikahi kēia mau laina ma nā kūlanakauhale akā ʻike ʻia paha ma nā wahi ʻōmaʻomaʻo kuaʻāina. ʻO nā mea hoʻokele ʻelua i loko o kahi conductor phase a me kahi conductor neutral, ʻo ia hoʻi nā conductors ola a kū ʻole. ʻO kahi hoʻonohonoho ʻē aʻe he hoʻonohonoho 4-conductor, ʻo ia ka laina 380V. Aia kēia me 3 uea ola a me 1 uea kūʻole.
