III. Ngā Āhuatanga
Ngaohiko Whakatauria
He pai rawa tēnei taura mō ngā momo mahi hiko e pā ana ki te whakawhitiwhiti kōrero me te whakahaere, me te ngaohiko whakatauranga o Uo/U: 300/500V. Mā tēnei awhe ngaohiko ka pumau te pūtake hiko mō ngā tohu e haria ana e ia, ka taea ai te whakahaere pai me te pono o ngā taputapu hono.
Te pāmahana kua whakatauhia
He whānuitanga pāmahana kua whakatauhia mō te taura, ā, ka taea te urutau ki ngā āhuatanga rerekē. I roto i ngā whakaurunga pumau, ka taea te mahi i roto i te whānuitanga pāmahana mai i te -40ºC ki te +80ºC, engari mō ngā āhuatanga piko, ko te whānuitanga mai i te 0ºC ki te +50ºC. Mā tēnei whānuitanga o te ātete pāmahana ka taea te whakamahi i roto i ngā āhuarangi rerekē, mai i te tino makariri ki ngā taiao tino wera, me te kore e whakaiti i te mahi.
Te Pūtoro Piko Iti rawa
He āhuatanga nui te pūtoro piko iti rawa o te 12D. Mā tēnei ka whakatau te nui o te piko o te taura i te wā tāutanga me te kore e pakaru tōna hanganga o roto. He mea nui tēnei ngāwari o te piko mō te arahi i te taura i roto i ngā whakatakotoranga tāutanga rerekē, ahakoa i roto i ngā wāhi kuiti, i ngā arai rānei.
IV. Te Hanganga
Kaiārahi
Mō ngā horahanga whakawhiti i waenga i te 0.5mm² - 0.75mm², ka whakamahia e te taura ngā ara iahiko parahi ngāwari o te Akomanga 5. He tino ngāwari ēnei ara iahiko, he mea whai hua i ngā tono e hiahiatia ana te ara o te taura mā roto i ngā piko kikī, i ngā wāhi rānei e tika ana kia nekehia.
