ʻO ka uea THW kahi mea uea uila maʻamau i loaʻa nā mea maikaʻi o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ʻaʻahu, ka mana uila kiʻekiʻe, a me ka hoʻokomo maʻalahi.Hoʻohana nui ʻia ka uea THW i nā laina hale noho, kalepa, luna, a me lalo o ka ʻāina, a ua lilo kona hilinaʻi a me ka hoʻokele waiwai i kekahi o nā mea uea i makemake ʻia i ke kūkulu ʻana a me nā ʻoihana uila.
He aha ka uwea THW
ʻO ka uwea THW kahi ʻano o ka uwea uwila kumu nui i haku ʻia me ka mea hoʻokele i hana ʻia me ke keleawe a i ʻole ke alumini a me kahi mea hoʻokaʻawale i hana ʻia me ka polyvinyl chloride (PVC).Kū ʻo THW no nā Plastics High-Temperature Weather-resistant Aerial Cable.ʻAʻole hiki ke hoʻohana ʻia kēia uea no nā ʻōnaehana hoʻolaha i loko wale nō akā no nā laina uea ma luna a me lalo, me ka nui o nā noi.Hoʻohana nui ʻia ka uea THW ma ʻAmelika ʻĀkau a me nā wahi ʻē aʻe a kaulana loa.
Nā hiʻohiʻona o ka uwea THW
1.High wela pale, THW uea hoʻohana PVC mea e like me ka insulation papa, e hana i ka uea i maikai kiʻekiʻe-mehana kuʻekuʻe a hiki ke kuʻi kiʻekiʻe hana wela a me ka ukana o kēia manawa.No laila, kūpono loa ka uea THW no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe.
2.Wear kū'ē, ua hana 'ia ka uea waho o THW me ka mea PVC, hiki ke pale pono i ka uwea mai ka lole a me ka poino.ʻAʻole pili kēia uea i nā mea kino kino a i ʻole kemika a hiki ke mālama i kāna hana maikaʻi no ka manawa lōʻihi.
3.High voltage mana, THW wires he kiʻekiʻe voltage-bearing capacity a hiki ke hana me ka palekana ma lalo o nā kūlana kiʻekiʻe.Hiki i kēia uea ke kū i ka volta kiʻekiʻe o 600V, hiki ke hoʻokō i nā pono o ka hapa nui o nā noi noho a me nā ʻoihana.
4.Easy e hoʻouka, THW uea mea maʻalahi, hana ia mea loa oluolu e hoʻouka a me ka uea.Ma muli o kona elasticity a me ka maʻalahi, hiki ke maʻalahi a wili ʻia ke kelepona THW, e ʻoi aku ka maʻalahi o ka hoʻonohonoho ʻana.
Hoʻohana i ka uwea THW
1. Noho a me ka hoʻohana pāʻoihana, THW wire ka mea nui o nā kaapuni i loko a me nā ʻōnaehana hoʻolaha o nā hale, i hoʻohana mau ʻia no ka hoʻolako ʻana i ka mana o nā mea pono hale like ʻole e like me nā kukui, nā kumu, nā televise, a me nā ea.
2.Overhead cable laina, no ka THW wire's high-temperature resistance and wear resistance, hiki iā ia ke pale i nā kūlana o ka wā a me nā hopena o waho, no laila ua hoʻohana nuiʻia i nā laina laina laina.
3.Underground cable laina, hiki i ka insulation layer o THW wire ke pale aku i ka uea mai ka hoʻopili ʻana me ka wai a i ʻole nā wahi ʻē aʻe o waho, no laila e hoʻohana pinepine ʻia i nā laina laina lalo.Hiki i kēia uea ke pale aku i ka haʻahaʻa a me nā kaiapuni pulu a hiki ke pale aku i ka uea mai ka ʻino a me ka ʻaʻahu.
THW uwea VS.Uea THWN
ʻO ka uea THW, ka uea THHN a me ka uea THWN nā huahana kumu hoʻokahi kumu.Ua like loa nā uea THW a me nā uea THWN i ka helehelena a me nā mea waiwai, akā hoʻokahi ʻokoʻa nui ma waena o lākou ʻo ka ʻokoʻa o ka insulation a me nā mea lole.Hoʻohana nā uea THW i ka pale ʻana i ka polyvinyl chloride (PVC), aʻo nā uea THWN e hoʻohana i ka hoʻoheheʻe thermoplastic polyethylene (XLPE) kiʻekiʻe.Ke hoʻohālikelike ʻia me PVC, ʻoi aku ka maikaʻi o XLPE i ka hana, me ka ʻoi aku ka maikaʻi o ka wai a me ka pale wela.ʻO ka mea maʻamau, hiki i ka mahana hana o THWN uea ke hiki i 90 ° C, ʻoiai ʻo ka THW uea he 75 ° C wale nō, ʻo ia hoʻi, ʻoi aku ka ikaika o ka wela THWN.
THW uwea VS.Uea THHN
ʻOiai ua haku ʻia nā uea THW a me nā uea THHN i nā uea a me nā ʻāpana hoʻokaʻawale, ʻo ka ʻokoʻa o nā mea insulation e alakaʻi i kā lākou hana ʻokoʻa ma kekahi mau ʻano.Hoʻohana nā uea THW i nā mea polyvinyl chloride (PVC), aʻo nā uea THHN e hoʻohana i ka resin epoxy acrylic resin (THERMOPLASTIC HIGH HEAT RESISTANT NYLON), e paʻa mau ana i nā wela kiʻekiʻe.Eia kekahi, ʻoi aku ka palupalu o nā uea THW ma mua o nā uea THHN e kūpono i nā hiʻohiʻona noiʻi lehulehu.
ʻOkoʻa nā uea THW a me nā uea THHN i ka hōʻoia.ʻO UL a me CSA, nā hui hōʻoia hoʻonaʻauao nui ʻelua ma ʻAmelika Hui Pū ʻIa a me Kanada, hāʻawi i ka palapala hōʻoia no nā uwea THW a me THHN.Eia nō naʻe, ʻokoʻa iki nā koina hōʻoia no nā mea ʻelua.Pono ka uwea THW e hōʻoia i ka UL, ʻoiai ʻo THHN uea e hoʻokō i nā koi o nā keʻena hōʻoia UL a me CSA.
No ka hōʻuluʻulu ʻana, ʻo ka uea THW kahi mea uea i hoʻohana nui ʻia, a ua lilo kona hilinaʻi a me ka hoʻokele waiwai i kekahi o nā mea uea i makemake ʻia no ka ʻoihana kūkulu a me ka ʻoihana uila.He hana maikaʻi loa ka uea THW a hiki ke hoʻokō i nā pono o nā manawa like ʻole, e lawe mai i ka maʻalahi a me ka palekana i ko mākou ola a me ka ʻoihana.
