Tukuna he ĪmēraKo ngā taura hiko waenga-ngaohiko kua whakamahanatia 12.7-22kV-XLPE e whakamahia ana mō ngā whatunga tohatoha hiko me ngā taura hiko āwhina i roto i ngā taiao rerekē. Mā te ārai whakauru ka taea te tanu tika hei ārai i te ru hiko me te kino. Ko te momo AS/NZS 12.7-22kV-XLPE he taura hiko waenga-ngaohiko i hangaia kia rite ki te Paerewa Ahitereiria/Aotearoa AS/NZS 1429.1. He pai mō te tāutanga pumau i roto i ngā whatunga tuku hiko i roto i ngā taiao o roto, o waho hoki, ā, ka taea te whakatakoto ki roto i ngā paipa taura, ki runga i ngā paepae taura, ki raro rānei i te whenua. He pai mō ngā pūnaha iahiko hapa nui tae atu ki te 10kA/1 hēkona. Kei te wātea ngā hanganga me ngā kaha iahiko hapa teitei ake mēnā ka tonoa.
Te Hanganga:
Kaiārahi:He parahi, he konumohe rānei, he porowhita te aho, he porowhita te aho kiato.
Te whakamarumaru:XLPE, TR-XLPE, EPR rānei.
Parenga whakarewa:Parenga waea parahi (CWS), Parenga rīpene parahi (CTS).
Te hipoki:Puranga konumohe kōpikopiko (CAS), Puranga parahi kōpikopiko (CCU), Kowiri tira kōpikopiko (CSS).
Te Whakamahinga Pū:Whakangungu waea konumohe (AWA), Whakangungu waea rino (SWA), Whakangungu waea kowiri tira (SSWA).
Te tiaki i ngā moko:Pūkahu nairona polyamide, Rīpene parahi takirua (DBT), Cypermethrin.
Ngā taura tāutanga:12D (PVC anake) 15D (HDPE).
I te wā tāutanga:18D (PVC anake) 25D (HDPE).
Awhe pāmahana:
Te pāmahana tāutanga iti rawa: 0°C
Te pāmahana whakahaere mōrahi: +90°C
Te pāmahana whakahaere iti rawa: -25°C
Ngā taura Ngaohiko Waenga kua hoahoatia kia rite ki te hoahoa:
Mō te whai huatanga me te roa o te wā, me whakarite ia taura MV kia rite ki te tāutanga engari he wā anō ka hiahiatia he taura tino motuhake. Ka taea e ā mātou tohunga taura MV te mahi tahi me koe ki te hoahoa i tētahi otinga e rite ana ki ō hiahia. I te nuinga o te wā, ka pāngia te rahi o te mata whakarewa e ngā whakaritenga, ka taea te whakarite kia rerekē ai te kaha o te ara iahiko poto me ngā whakaritenga whenua.
I ia wā, ka whakaratohia ngā raraunga hangarau hei whakaatu i te pai me te whakaritenga kua whakatikatikaina mō te hanga. Ko ngā otinga kua whakaritea katoa ka whai whakamātautau whakarei ake i roto i tā mātou Whare Whakamātautau Taura MV.
