Te Whānui o te hononga wero whakamātao (IPC)
He hononga wero, he ngāwari te tāutanga, kāore e hiahiatia kia tangohia te koti taura.
Nati wā, he pumau te pēhanga wero, kia mau tonu te hononga hiko pai, ā, kia kore e kino te mata.
He anga tuitui-ā-roto, he ātete-makuku, he ātete-wai, he ātete-waikura hoki, ka roa ake te roa o te whakamahinga o te mata me te hononga kua whakamahanatia.
I tangohia he papa honohono motuhake, e whakamahia ana ki te hononga o Cu(Al) me Cu(Al) me Cu me Al rānei.
He iti te ātete hononga hiko, he iti iho i te 1.1 ngā wā o te ātete o te arataki peka me te roa ōrite te ātete hononga.
He tinana motuhake kua whakamahanatia, he ātete ki te māramatanga me te koroheketanga taiao, ko te kaha whakamahana ka tae ki te 12KV.
Hoahoa mata pewa, e pā ana ki te hononga he rite te diameter (rerekē), he whānui te whānuitanga hononga (0.75mm2 ~ 400mm2).
(Whakamātautau mahi)
Te mahi ā-mīhini: ko te kaha pupuri o te rawhi waea he 1/10 te nui ake i te kaha whati o te mata. E tutuki ana i te GB2314-1997.
Te pikinga o te pāmahana: i raro i te āhua o te iahiko nui, he iti ake te pikinga o te pāmahana o te hononga i tērā o te arai hononga.
Mahi porowhita wera: e rite ana ki te GB/T2317.3-2000, te paerewa whakamātautau porowhita wera mō te hikohiko.
Te mahi ārai wai: e tutuki ana i ngā whakaritenga e tika ana i te Wāhanga 2 o GB/T13140.4-1998.
Ātete ki te mahi waikura: i raro i te āhua o te SO2 me te kohu tote, ka taea e ia te mahi i ngā whakamātautau porowhita e toru ngā wā o te tekau mā whā ngā rā.
Te mahi koroheketanga taiao: i raro i te āhuatanga o te ultraviolet, te radiation, maroke me te makuku, whakaatuhia mēnā he huringa o te pāmahana me te kaha wera mō ngā wiki e ono.
Te mahi ātete ahi: ka taea e te rauemi whakamarumaru o te hononga te tu atu ki te whakamātautau miro kanapa. Kia tutuki ki ngā whakaritenga o te Upoko 4-10 o GB/T51 69.4.
