Tukuna he ĪmēraHe pai ngā taura hiko waenga-ngaohiko 19-33kV XLPE kua whakamahanatia mō ngā whatunga tohatoha, ngā whatunga tuku tuarua rānei, ā, ko te nuinga o te wā koinei te pūtake hiko matua mō ngā whatunga arumoni, ahumahi, me ngā whatunga noho tāone. He pai ēnei mō ngā pūnaha iahiko hapa nui me ngā iahiko hapa whakatauranga tae atu ki te 10kA/1 hēkona. Ka taea te whakarato i ngā hanganga he kaha iahiko hapa whakatauranga teitei ake mēnā ka tonoa.
Te Hanganga:
Rauemi arataki:Ko ngā kōwhiringa ko te parahi, te konumohe rānei kua werohia, te parahi totoka me te parahi kukū.
Parenga arai:He matū haurua-arahi e whakamahia ana mā te whakapūtanga ki runga i te ara iahiko.
Te whakamarumaru:He matū polyethylene honohono-whiti (XLPE) e rite ana ki te AS/NZS 3808. He pai ake te ātete wera me te ātete ki te pakū o te XLPE ki te PVC.
Parenga ārai:He matū ara iahiko kua whakapūkarahia e hipoki ana i te paparanga whakamarumaru.
Te pāmahana whakahaere mōrahi:Ka taea e ngā kaiārahi hiko te mahi i te pāmahana mōrahi tonu o te 90°C.
Te pāmahana poto-poto mōrahi:Ka taea e te taura te tu atu i te pāmahana poto mōrahi o te 250°C mō te 5 hēkona.
Parenga whakarewa:He mea hanga noa mai i te waea parahi kua whakamahanatia, i te rīpene parahi rānei.
Te whakangungu rakau whakarewa:Ko ngā momo ārai ko te waea rino piauau (SWA) mō ngā taura matua-maha me te waea konumohe (AWA) mō ngā taura matua-kotahi.
Rauemi o te Puranga:
Ko te hipoki paerewa he mea hanga ki te PVC pango 5V-90.
He pai ngā kōwhiringa LSZH (Low Smoke Zero Halogen) mō roto, mō ngā wāhi tūmatanui, me ētahi atu taiao e hiahia ana kia whai whakaaro ki te haumaru ahi.
Tērā pea ka tāpirihia he koti polyamide (nailona) kua whakaputaia hei ātete ki ngā moko.
Ka taea hoki te whakamahi i te hipoki o waho o te HDPE (High-Density Polyethylene) hei huarahi kē atu.
