ʻO ka wehewehe a me ka hoʻohana ʻana i ka alumini conductor steel-reinforced (ACSR)

Hoʻohana ʻia ka ACSR conductor a i ʻole ka alumini conductor steel i hoʻoikaika ʻia e like me ka hoʻouna ʻana ma luna o ke poʻo a ma ke ʻano he uwea mahele mua a lua. ʻO nā kaula waho he alumini maʻemaʻe kiʻekiʻe, koho ʻia no kāna conductivity maikaʻi, haʻahaʻa haʻahaʻa, haʻahaʻa kumu kūʻai, kūʻē i ka corrosion a me ke kūpaʻa koʻikoʻi mechanical. ʻO ke kaula waena he kila no ka ikaika hou aku e kōkua i ke kākoʻo ʻana i ke kaumaha o ke alakaʻi. ʻOi aku ka ikaika o ke kila ma mua o ka alumini e hiki ai ke hoʻonui i ka ʻenekini mechanical e kau ʻia ma luna o ka conductor. He haʻahaʻa ka elastic a me ka inelastic deformation ke kila (permanent elongation) ma muli o ka hoʻouka mechanical (e laʻa ka makani a me ka hau) a me ka coefficient haʻahaʻa o ka hoʻonui wela ma lalo o ka hoʻouka ʻana o kēia manawa. Hāʻawi kēia mau waiwai iā ACSR i ka haʻahaʻa haʻahaʻa ma mua o nā conductors aluminika āpau. E like me ka International Electrotechnical Commission (IEC) a me The CSA Group (ma mua o ka Canadian Standards Association a i ʻole CSA) hui inoa inoa, ua koho ʻia ʻo ACSR A1/S1A.

ʻO ka alumini alumini a me ka huhū i hoʻohana ʻia no nā kaula waho ma ʻAmelika Hui Pū ʻIa a me Kanada ʻo 1350-H19 maʻamau a ma nā wahi ʻē aʻe ʻo 1370-H19, kēlā me kēia me 99.5+% alumini. Ua wehewehe ʻia ke ʻano o ka alumini e ka suffix o ka mana alumini, i ka hihia o H19 ʻoi aku ka paʻakikī. No ka hoʻolōʻihi i ke ola o nā kaula kila i hoʻohana ʻia no ke kumu conductor, ua galvanized maʻamau lākou, a i uhi ʻia me ka zinc e pale ai i ka pala. ʻOkoʻa nā anawaena o nā kaula i hoʻohana ʻia no nā kaula alumini a me ke kila no nā mea hoʻokele ACSR like ʻole.

Ke hilinaʻi nei ke kaula ACSR i ka ikaika tensile o ka alumini; hooikaika wale ia e ke kila. Ma muli o kēia, ua kaupalena ʻia kona mahana hana hoʻomau i 75 °C (167 °F), ʻo ka mahana e hoʻomaka ai ka alumini e hoʻopili a palupalu i ka manawa. No nā kūlana e koi ʻia ai nā mahana hana kiʻekiʻe, hiki ke hoʻohana ʻia ke alumini-conductor steel-supported (ACSS).

Hoʻoholo ʻia ka waiho ʻana o kahi alakaʻi e nā manamana lima ʻehā; Hoʻoholo ʻia ka ʻaoʻao "'ākau" a i ʻole "hema" o ka waiho ʻana ma muli o ka pili ʻana i ke kuhikuhi manamana lima mai ka lima ʻākau a i ʻole ka lima hema. ʻO ka alumini ma luna (AAC, AAAC, ACAR) a me nā mea hoʻokele ACSR ma USA e hana mau ʻia me ka papa conductor waho me kahi waiho lima ʻākau. Ke hele nei i ke kikowaena, loaʻa i kēlā me kēia papa nā waiho ʻokoʻa. He ʻokoʻa kekahi ʻano mea hoʻokele (e laʻa me ka mea hoʻokele keleawe ma luna o ke poʻo, OPGW, kila EHS) a aia ka lima hema ma ka mea hoʻokele waho. Ua kuhikuhi kekahi mau ʻāina ʻAmelika Hema i ka waiho lima hema no ka papa alakaʻi o waho ma kā lākou ACSR, no laila ua ʻokoʻa kēlā mau mea ma mua o nā mea i hoʻohana ʻia ma USA.

ʻO ACSR i hana ʻia e mākou hiki ke hālāwai me ASTM, AS, BS, CSA, DIN, IEC, NFC etc.
