He aha ka ʻokoʻa ma waena o Thhn a me PV uea?

THHN (Thermoplastic High Heat-resistant Nylon-coated) uea aUea PV (Photovoltaic).ʻelua mau ʻano uwea uila, akā ua hoʻolālā ʻia lākou no nā noi like ʻole a loaʻa nā ʻano ʻokoʻa:

Noi:

Uea THHN: Hoʻohana mau ʻia ka uea THHN i nā noi wili i loko, e like me nā hale noho a me nā hale kalepa. He kūpono ia no ka uwea maʻamau ma nā wahi maloʻo a pulu paha, me nā ʻauwaʻa a me nā pā kaula.

Uea PV: Uea PV, i ikeiauwea lā, ua hoʻonohonoho pono ʻia no ka hoʻohana ʻana i nā ʻōnaehana mana photovoltaic, e like me nā hoʻonohonoho ʻana o ka lā. Hoʻohana ʻia ia e hoʻopili i nā panela lā i nā mea hoʻohuli, pahu hui pū, a me nā mea ʻē aʻe o nā ʻōnaehana ikehu lā.

Kūkulu ʻia:

Uea THHN: ʻO ka uea THHN ka mea maʻamau i nā mea hoʻokele keleawe me ka PVC (Polyvinyl Chloride) insulation a me kahi uhi nylon no ka pale a me ka lōʻihi. Loaʻa ia ma nā ʻano nui conductor a me nā mānoanoa insulation.

Uea PV: Ua hana ʻia ka uea PV me ka hoʻohana ʻana i nā mea kūʻē i ka radiation UV, nā wela wela, a me nā kaiapuni waho. Hōʻike maʻamau ia i nā mea hoʻokele keleawe i hoʻopaʻa ʻia me ka polyethylene (XLPE) i hoʻopili ʻia a me kahi lole pale pale UV kūikawā. Loaʻa ka uea PV i nā nui kikoʻī a me nā hoʻonohonoho e hoʻokō i nā koi o nā ʻōnaehana mana lā.

Ka Mahana a me ke Kaiapuni:

Uea THHN: Ua helu ʻia ka uea THHN no ka hoʻohana ʻana i nā mahana a hiki i 90°C (194°F) ma nā wahi maloʻo a hiki i 75°C (167°F) ma nā wahi pulu. ʻAʻole i hoʻolālā ʻia no ka ʻike ʻana o ka lā i waho a i ʻole.

Uea PV: Ua hana pono ʻia ka uea PV e kū i nā kūlana o waho, e like me ka ʻike ʻana i ka lā, ka ua, ka hau, a me nā wela wela. Ua helu ʻia no ka hoʻohana ʻana i nā mahana mai -40°C (-40°F) a hiki i 90°C (194°F) a ua pale ʻo UV no ka pale ʻana i ka pōʻino mai ka ʻike ʻana o ka lā.

Nā palapala hōʻoia a me nā kūlana:

Uaea THHN a meUea PVpono paha e hoʻokō i nā palapala hōʻoia a me nā kūlana ma muli o ka noi a me ka mana. Pono pinepine ka uea PV e hoʻokō i nā kūlana ʻoihana e like me UL 4703 no nā uwea lā.
