I te mea e whakamahia ana ngā taura i roto i te keri i ngā āhuatanga uaua me te taiao kino, he nui te hau me te paru, ā, he ngāwari te kitea, ko ngā taura hiko kirihou ārai mura ehara i te mea ko ngā āhuatanga anake kua whakahuatia i te upoko tuatahi o tēnei pukapuka, engari he āhuatanga ārai mura anō hoki. I roto i ēnei, ko te mea he 50mm te horahanga whakawhiti mōrahi me runga ake me whakamātautau mura o te Waea Hiko Kohikohi momo A me te taura. Mena he iti iho i te 50mm², me whakamātautau mura o te waea hiko kohikohi momo B me te taura.
1. Te pāmahana whakahaere teitei
2. He kaha te pumau o te ratonga me te ātete ahi, e whai hua ana ki te whakarite i te roa o te ora ratonga o te taura.
3. Ārai pahūtanga
4. He iti te diameter o waho
5. Te kaha miihini teitei
6. Te kaha kawe iahiko nui
7. Te ātete nui ki te waikura
He pai tēnei momo taura mō te whakamahi i roto i te whakaurunga pumau i roto i ngā raina tuku/tohatoha mō ngā hiko kua whakatauria i raro i te 10kV pērā i te wāhi mai i te rūma tohatoha pokapū ki te rūma hiko-ā-ringa, te teihana whakawhiti hiko movab-e, te awheawhe keri whānui me te taputapu whakawhiti. He āhuatanga ātete mura te taura.
