Te Whakawhanake Taura mō ngā Pūnaha Mana Teitei
Pendahuluan
I tēnei ao hou, kua noho te hiko hei mea nui, e tautoko ana i ngā āhuatanga katoa o te oranga tangata. Mai i ngā whare me ngā ahumahi ki ngā pūnaha kawe waka, me whai pūtake hiko pono, rawaka hoki ngā mea katoa. He wāhanga nui ngā taura i roto i te tohatoha hiko. Mō ngā pūnaha hiko teitei, ko te whanaketanga taura, inā koa, he mea whakakī ki te auahatanga me te hangarau teitei.
Ko ngā pūnaha hiko ngaohiko-tiketike (HVPS) e pā ana ki ngā whatunga me ngā wāhanga e whakahaere ana i te tohatoha o te hiko ngaohiko-tiketike, he maha ngā wā kei runga ake i te 35 kV. I runga i ngā ngaohiko teitei me whakahaere e rātou, me tutuki i ngā taura e whakamahia ana ngā whakaritenga motuhake kia pai ai te mahi me te haumaru. Ka matapakihia e tēnei tuhinga ngā āhuatanga rerekē o te whanaketanga taura mō ngā pūnaha ngaohiko-tiketike, mai i ngā rauemi me te hoahoa ki ngā wero me ngā auahatanga hou.
Rauemi Taura
Ko te whiriwhiri i te rauemi tika te taahiraa tuatahi ki te whakawhanake i ngā taura mō ngā pūnaha mana-teitei. Ko ngā rauemi e whakamahia whānuitia ana ko ēnei e whai ake nei:

– Konumohe (Al): Ka whakamahia te konumohe ina whakaarohia te utu. He iti ake tōna kawe hiko i te parahi, engari he mama ake, he iti ake hoki te utu e tino kitea ai.
2. Kaiwhakawehe
Me whai āhuatanga hiko, ā-pūkaha hoki te rauemi whakamahana e whakamahia ana kia tu atu ai i ngā ngaohiko teitei me ngā āhuatanga taiao kino.
– Polyethylene Hononga-Whatunga (XLPE): Ko te XLPE te rauemi ārai e whakamahia whānuitia ana mō ngā taura ngaohiko teitei. He pai ake ngā āhuatanga wera me te hiko.
– Rapa Ethylene Propylene (EPR): He tino pai te ātete wera a te EPR, ā, he kaha hoki ōna āhuatanga hangarau. He mea tino pai tēnei rauemi mō ngā mahi i raro i te whenua, i raro rānei i te wai.
3. Te Uwhi o Waho
– Polyvinyl Chloride (PVC): He maha ngā wā ka whakamahia te PVC nā te mea he ātete ki te ahi, te hinu me ngā matū.
– Polyethylene (PE): He tino kaha te PE ki te miihini, ā, he ātete hoki ki te ahotea hiko, he mea tino pai mō ngā mahi o waho.
Hoahoa Taura
He maha ngā āhuatanga nui o te hoahoa taura mana-teitei hei whakarite i te mahi tino pai me te whakaiti i ngā mōrearea pea.
1. Hanganga Papa
He maha ngā paparanga o ngā taura mana-nui, tae atu ki ngā kaiārahi hiko, te whakamarumaru hiko, he mata ārahi-haurua, me te hipoki tiaki. He mahi motuhake tā ia paparanga hei whakarite i te pumau me te haumaru o te taura.
2. Parenga Hiko
Ka whakamahia te parenga hiko hei whakahaere i ngā papa hiko me te whakaiti i te pokanoa. Ko te tikanga, he mea hanga ēnei parenga ki ngā rauemi kawe hiko pēnei i te parahi, te konumohe rānei.
3. Whakamatao
I ētahi wā, me whai pūnaha whakamatao hei whakahaere i te wera e puta mai ana i ngā iahiko teitei. Ko te wai whakamatao he wai e rere ana i roto i ngā taura, he pūnaha whakamatao o waho rānei.
4. Te Tiakitanga Ā-Mīhini
He maha ngā wā ka whakatakotoria ngā taura mana-teitei ki ngā taiao kino, nō reira ka whakamahia ngā ārai ā-ringa pēnei i te maitai kore waikura, te whakakikorua maitai rānei hei tiaki i te taura mai i ngā kino tinana.
Ngā Wero i roto i te Whakawhanaketanga Taura Hiko Teitei
1. Te waikura
Ka taea e ngā āhuatanga taiao pēnei i te haumākū me te pānga o ngā matū te whakapōrearea, ā, ka kino pea ngā wāhanga taura. Mā te whakamahi i ngā rauemi ārai-waikura me ngā paninga motuhake ka taea te whakaiti i tēnei mōrearea.
