ʻO ke kaula kū'ē he kaula ia i manaʻo ʻia no ka hana ʻana i nā pale uila (i hoʻohana ʻia e kāohi i ka nui o ke au i loko o kahi kaapuni). ʻOi aku ka maikaʻi inā he kiʻekiʻe ke kū'ē ʻana o ka mea hao i hoʻohana ʻia, ʻoiai hiki ke hoʻohana ʻia kahi kaula pōkole. I nā kūlana he nui, ʻo ke kūpaʻa o ka pale he mea nui ia, a no laila ke pāʻani nui nei ke koina mahana o ka mea hao o ka kū'ē ʻana a me ke kū'ē ʻana i ka palaho i ke koho ʻana i nā mea.

Ke hoʻohana ʻia ke uea kū'ē no nā mea hoʻomehana (i loko o nā mea hoʻomehana uila, nā toasters, a me nā mea like), he mea nui ke kū'ē kiʻekiʻe a me ke kū'ē'ē oxidation.

I kekahi manawa, ua hoʻokaʻawale ʻia ke kaula kū'ē e ka pauka seramika a ua uhi ʻia i loko o kahi paipu o kahi hui hao ʻē aʻe. Hoʻohana ʻia kēlā mau mea hoʻomehana i loko o nā umu uila a me nā mea hoʻomehana wai, a ma nā ʻano kūikawā no nā kapuahi kuke.
ʻO ke kaula uea he mau kaula hao i wili ʻia i loko o kahi helix e hana ana i kahi "kaula" hui pū ʻia, ma ke ʻano i kapa ʻia ʻo "kaula kau". ʻO ke kaula uea nui aʻe ke anawaena he mau kaula he nui o ia kaula i kau ʻia ma ke ʻano i kapa ʻia ʻo "uweai kau ʻia”.

ʻO ka maʻamau, hana ʻia nā uea kila no nā kaula uea me ke kila kalapona ʻaʻole me ka nui o ke kalapona he 0.4 a 0.95%. ʻO ka ikaika kiʻekiʻe loa o nā uea kaula e hiki ai i nā kaula uea ke kākoʻo i nā ikaika tensile nui a holo ma luna o nā puʻu me nā anawaena liʻiliʻi.

Ma nā kaula i kapa ʻia ʻo cross lay, keʻa nā uea o nā papa like ʻole kekahi i kekahi. Ma nā kaula like i hoʻohana nui ʻia, ua like ka lōʻihi o nā papa uea a pau a ua like nā uea o nā papa ʻelua i hoʻopili ʻia, e hopena ana i ka pilina linear. Kākoʻo ʻia ke uea o ka papa waho e ʻelua mau uea o ka papa o loko. He mau hoalauna kēia mau uea ma ka lōʻihi holoʻokoʻa o ke kaula. Hana ʻia nā kaula like i hoʻokahi hana. ʻOi aku ka lōʻihi o ke ahonui o nā kaula uea me kēia ʻano kaula ma mua o nā mea (kākaʻikahi ka hoʻohana ʻia) me nā kaula like. Loaʻa i nā kaula like me ʻelua mau papa uea ke kūkulu ʻia ʻo Filler, Seale a i ʻole Warrington.

Ma ke kumu, he mau kaula poepoe nā kaula wili no ka mea he hui o nā papa o nā uea i kau ʻia ma luna o ke kikowaena me ka liʻiliʻi o hoʻokahi papa o nā uea i kau ʻia ma ke ʻano ʻē aʻe i ka papa o waho. Hiki ke ana ʻia nā kaula wili i ke ʻano ʻaʻole lākou e wili ana ʻo ia hoʻi ma lalo o ke kaomi ʻana kokoke i ka ʻole o ka torque kaula. ʻO ke kaula wili hāmama he mau uea poepoe wale nō. ʻO ke kaula wili hapalua-paʻa a me ke kaula wili piha-paʻa mau he kikowaena i hana ʻia me nā uea poepoe. Loaʻa i nā kaula wili paʻa hoʻokahi a ʻoi aku paha nā papa o waho o nā uea profile. Loaʻa iā lākou ka pōmaikaʻi ʻo kā lākou kūkulu ʻana e pale ai i ke komo ʻana o ka lepo a me ka wai i kahi nui a pale pū ia iā lākou mai ka nalowale ʻana o ka lubricant. Eia kekahi, loaʻa iā lākou kekahi pōmaikaʻi koʻikoʻi loa ʻoiai ʻaʻole hiki i nā wēlau o kahi uea waho i haki ke haʻalele i ke kaula inā loaʻa iā ia nā ana kūpono.
ʻO ke kaula stranded i haku ʻia me kekahi mau kaula liʻiliʻi i hoʻopili ʻia a i ʻōwili ʻia paha e hana i kahi alakaʻi nui aʻe. ʻOi aku ka maʻalahi o ke kaula stranded ma mua o ke kaula paʻa o ka ʻāpana ʻāpana like. Hoʻohana ʻia ke kaula stranded i ka wā e pono ai ke kū'ē kiʻekiʻe i ka luhi metala. ʻO ia mau kūlana e pili ana i nā pilina ma waena o nā papa kaapuni i nā mea hana papa kaapuni he nui i paʻi ʻia, kahi e hoʻoulu ai ka paʻakikī o ke kaula paʻa i ka nui o ke kaumaha ma muli o ka neʻe ʻana i ka wā o ka ʻākoakoa a i ʻole ka lawelawe ʻana; Nā kaula laina AC no nā mīkini; mea kaniuweas; nā uwea ʻiole kamepiula; nā uwea ʻelekole kuʻihao; nā uwea hoʻokele e hoʻohui ana i nā ʻāpana mīkini neʻe; nā uwea mīkini eli; nā uwea mīkini hope; a me nā mea ʻē aʻe he nui.
