Hoʻohana ʻia nā kaula alumini ma waho i nā keʻena hoʻolaha.Lawe lākou i ka mana mai nā laina pono a hiki i nā hale ma o ka weatherhead.Ma muli o kēia hana kūikawā, ua wehewehe ʻia nā kaula e like me nā kaula hāʻule lawelawe.ʻO nā uwea alumini ma luna o nā ʻano ʻano duplex, triplex, a me quadruplex.Hoʻohana ʻia nā kaula Duplex i nā laina mana hoʻokahi, ʻoiai ua hoʻohana ʻia nā kaula quadruplex i nā laina mana ʻekolu.Hoʻohana wale ʻia nā kaula Triplex e lawe i ka mana mai nā laina pono i nā mea kūʻai aku.
Aluminum conductorUa hana ʻia nā kaula i nā moʻo alumini 1350-H19 palupalu.Hoʻopili ʻia lākou me kahi polyethylene thermoplastic extruded a i ʻole polyethylene cross-linked no ka pale ʻana mai nā pilikia kaiapuni waho.Hoʻolālā ʻia nā kaula me kahi mahana hana a hiki i ka 75 degere a me ka helu voltage o 600 volts.
