ʻO nā kaula hāʻule lawelawe luna nā kaula e hoʻolako i nā laina mana luna o waho. He ʻano hoʻoili mana hou lākou ma waena o nā alakaʻi luna a me nā kaula lalo o ka honua, kahi i hoʻomaka ai ka noiʻi a me ka hoʻomohala ʻana i ka hoʻomaka ʻana o nā makahiki 1960.
Ua haku ʻia nā kaula hāʻule lawelawe luna me kahi papa insulation a me kahi papa pale, e like me ke kaʻina hana o nā kaula i hoʻopili ʻia. ʻOiai ʻoi aku ka maʻalahi o lākou i ka hoʻopilikia ʻana o waho a ʻaʻole maikaʻi ke ʻano, hoʻohana nui ʻia lākou ma nā wahi i paʻakikī ai ke kau ʻana i nā kaula ma lalo o ka honua ma muli o ko lākou hilinaʻi kiʻekiʻe o ka lako mana, kūpaʻa, a me ka mālama pono.
Pehea mākou e koho ai i ke kaula hāʻule lawelawe overhead?
ʻO nā ʻano ʻekolu o nā kaula lawelawe alumini he kaula lawelawe duplex, kaula lawelawe triplex, a me ke kaula lawelawe quadruplex. ʻOkoʻa lākou e like me ka helu o nā alakaʻi a me nā noi maʻamau. E nānā pōkole kākou i ke kuleana o kēlā me kēia.
Hoʻohana ʻia nā kaula hāʻule lawelawe Duplex me ʻelua mau alakaʻi i nā laina mana hoʻokahi-pae no nā noi 120-volt. Hoʻohana pinepine ʻia lākou i nā ʻōnaehana kukui ma waho, me ke kukui alanui. Eia kekahi, hoʻohana pinepine ʻia lākou i ka ʻoihana kūkulu hale no ka lawelawe manawa pōkole. ʻOiaʻiʻo leʻaleʻa- Ua kapa ʻia nā nui o ke kaula overhead duplex ʻAmelika ma muli o nā ʻano ʻīlio, me ka setter, shepherd, a me ka chow.
Hoʻohana ʻia nā kaula hāʻule lawelawe Triplex me ʻekolu mau alakaʻi e lawe i ka mana mai nā laina pono i nā mea kūʻai aku, ʻoi aku hoʻi, i ke poʻo o ke aniau. Eia hou, he moʻolelo hoihoi ko nā kaula hāʻule lawelawe triplex ʻAmelika i ko lākou inoa. Ua kapa ʻia lākou ma muli o nā ʻano holoholona kai, e like me nā nahesa, nā ʻūpā, a me nā pāpaʻi. ʻO nā inoa kaula ʻo Paludina, Valuta, a me Minex.
Ua hoʻolālā ʻia nā kaula hāʻule lawelawe Quadruplex me nā alakaʻi ʻehā e hoʻolako i nā laina mana ʻekolu-pae. Hoʻopili lākou i nā mea hoʻololi uila i kau ʻia ma ke pou, aia ka hapa nui ma nā wahi kuaʻāina, me nā poʻo lawelawe o ka mea hoʻohana hope. Ua kapa ʻia nā kaula Quadruplex e kū nei i nā koi o NEC ma hope o nā ʻano lio, e like me Gelding lāua ʻo Appaloosa.
Ke kūkulu ʻana i nā kaula hāʻule lawelawe alumini
ʻOiai ke ʻano like ʻole o nā kumu a me ka helu o nā alakaʻi, ua like ke kūkulu ʻana o nā uea lawelawe uila āpau ma luna. Hana ʻia nā alakaʻi o kēia mau kaula me ka alumini alloy 1350-H19,6201-T81 a i ʻole ACSR.
Loaʻa iā lākou kahi insulation polyethylene XLPE i hoʻopili ʻia e hāʻawi ana i ka pale nui mai nā pilikia o waho. ʻoiai, he kūpaʻa maikaʻi loa ia i ka makū, nā kūlana o ke aniau, a me ka hopena o nā kemika like ʻole. ʻO ka mahana hana o nā kaula alumini ma luna me ka insulation XLPE he 90 degere Celsius. I kekahi manawa, hiki ke hoʻopili ʻia ka insulation polyethylene ma kahi o ka insulation XLPE. I kēia hihia, ua hoʻemi ʻia ka mahana hana i 75 degere, he mea ia e noʻonoʻo ai i ka wā e noʻonoʻo ai i kāu papahana uila. ʻO ka helu voltage o nā uea lawelawe uila āpau ma luna he 600 volts.
Loaʻa i nā kaula lawelawe alumini āpau kahi alakaʻi kūlike ʻole a i ʻole he uea ʻelele. ʻO ka pahuhopu o ke alakaʻi ʻelele, ʻo ia ke hana i kahi ala kūlike ʻole no ka uila e pakele ai a pale aku i nā pōpilikia, he mea koʻikoʻi ia i ke kaiapuni o ke kaula waho. Hiki ke hana ʻia nā uea ʻelele me nā mea like ʻole, e like me AAC, ACSR, a i ʻole kekahi ʻano mea hoʻohuihui alumini.
Inā makemake ʻoe e loaʻa kahi kūkākūkā e pili ana i nā alakaʻi hāʻule lawelawe, e ʻoluʻolu e kelepona mai iā mākou.
