He aha nā pilikia o nā uwea kūpono ʻole a me nā kaula?

Uea a uweahe ʻāpana nui o nā huahana uila i hoʻohana ʻia e hoʻouna i ka uila, hoʻouna i ka ʻike a ʻike i ka hoʻololi ʻana i ka ikehu electromagnetic. He kuleana koʻikoʻi nā uwea a me nā kaula i nā hana hoʻokele waiwai a me ke ola kaiaulu. Hiki ke ʻōlelo ʻia ma nā wahi a pau e noho ana ka poʻe, ma nā wahi a pau e loaʻa ai ka hana, ka lawe ʻana a me nā hana waiwai āpau, pono ʻole nā ​​uea a me nā kaula. No laila, pili pono ka maikaʻi o nā uea a me nā kaula i ko mākou ola.

ʻO nā huahana kūpono ʻole ka nui o nā pilikia me ka hoʻolālā, ka nui conductor, ke kūpaʻa conductor, ka insulation a me ka ikaika tensile sheath ma mua o ka ʻelemakule. ʻO nā mea kūʻai aku e hoʻohana ana i ia mau huahana e maʻalahi i ka leakage, ka uila a me ke ahi. Ua kanu kēia mau huahana haʻahaʻa i nā pōʻino huna he nui no ka hana maʻamau o ka ʻōnaehana mana.

Ma hope o ka ulia ʻana o ka pae hoʻokahi (kaapuni pōkole) i kauwea a me na uwea, ʻO ka mea pale relay ka mea e wela ai nā uea a me nā kaula ma muli o ka hiki ʻole o ka hana hope loa e ʻoki i ka hewa, e hopena i ka puhi ʻana o ka papa insulation.

ʻO nā uwea a me nā kaula me ka ikaika tensile kūpono a me ka elongation ma mua o ka ʻelemakule ʻana o ka sheath insulation. ʻO ka ikaika tensile kūpono ʻole a me ka elongation o ka sheath insulating ma mua o ka ʻelemakule e hoʻopōkole pololei i ke ola lawelawe o nā uea a me nā kaula. Eia kekahi, i ka wā o ke kūkulu ʻana a i ʻole kahi kaiapuni kahi e paʻa ai ka mana no ka manawa lōʻihi a kiʻekiʻe ka wela, hiki i ka insulator ke haki, e hopena i nā conductors ola i hōʻike ʻia a me ka pilikia o nā pōkole pōkole uila.

ʻO nā uea me ke kūpaʻa conductor kūpono ʻole. ʻO ke kūpaʻa koʻikoʻi ka mea nui no ka loiloi ʻana inā kūpono ka mea conductor a me ka ʻāpana o nā uea a me nā kaula i nā koi. Ke ʻoi aku ke kūpaʻa o ka conductor i ka maʻamau, hoʻonui ʻia ka nalowale o ka manawa e hele ana i ka laina, e hoʻonui ai i ka wela o nā uea a me nā kaula. ʻO ke kumu nui o ke kūʻē ʻana i ka conductor kūpono ʻole i mea e hōʻemi ai i nā kumukūʻai, hoʻemi nā ʻoihana i nā mea keleawe, ʻo ia ka 80% o ke kumu kūʻai kumu, ma ka hōʻemi ʻana i ka ʻāpana cross-sectional o ka conductor a i ʻole ka hoʻohana ʻana i ke keleawe recycled me nā haumia kiʻekiʻe loa. 'O kēia ke kumu o ka conductor kū'ē ouwea a me na uweae ko'iko'i ma mua o ka ma'amau. I ke kaʻina o ka hoʻohana ʻana, ʻaʻole maʻalahi wale ka hoʻoulu ʻana i ke ahi, akā e hoʻolalelale pū i ka ʻelemakule o ka papa insulation i kāʻei ʻia a puni nā uea.
