Ko te Taura Whakamarumaru Kohuke (MI Cable) he taura ātete ahi mahi-teitei e hangai ana ki tētahi pūnaha rauemi taura kore-ora. He rerekē ki ngā taura tuku iho e whakawhirinaki ana ki ngā rauemi whakamahana polymer pēnei i te PVC,XLPE, meLSZH, ka hangaia te taura MI mā te whakamahi i te arataki parahi, he hipoki parahi kore hononga, me te rauemi whakamarumaru kore-waro konupora waikura (MgO) hei hanganga matua. Mā tēnei pūnaha rauemi ka whakatau i tōna mahi pumau i raro i ngā āhuatanga pāmahana teitei me te ahi.
Mai i te tirohanga o te whanaketanga o ngā rauemi taura, ka whakakorea e ngā pūnaha rauemi kore-waro ngā take o te pirau, te rewa, me te tukunga paowa paitini e puta ana i roto i ngā rauemi waro i raro i ngā pāmahana teitei. Nā tēnei ka waiho te taura MI hei otinga nui mō ngā taura ātete ahi, ngā taura pāmahana teitei, me ngā rauemi taura pūnaha hiko nui.
Hanganga me te Whakatakotoranga Rauemi
Ko te mahi a te taura MI e whakatauhia ana e tōna pūnaha rauemi taura matua. He mea hanga te ara iahiko ki te ara iahiko parahi tino parakore, e whakarato ana i te kawe hiko tino pai me te ātete iti, e hanga ana hei wāhanga matua o ngā rauemi taura hiko.
Ka whakamahia e te paparanga whakamarumaru te konupora waikura (whakamarumaru MgO), he rauemi whakamarumaru taura kore-waro noa me te ira rewa i runga ake i te 2800°C. Ka mau tonu te mahi hiko-kore pumau ahakoa i raro i ngā pāmahana tino kino, ā, koia te rauemi matua e āhei ai te ātete ki te ahi.
Ko te paparanga o waho he mea hanga ki te uhi parahi kore hononga, e whakarato ana i te tiaki ā-mīhini me te ātete ki te waikura. He pai hoki te kawe wera me te mahi tiaki hikohiko (EMI). Hei tāpiri, ka taea e te uhi parahi te mahi hei kawe whenua, hei whakahaere i te hoahoa pūnaha me te whakapai ake i te pono o te mahi.
Te Mahi Ahi me ngā Painga Rauemi
I raro i ngā āhuatanga ahi, ka nui haere ngā rerekētanga o ngā pūnaha rauemi. Ko ngā rauemi taura polymeric tuku iho ka tīmata te pirau wera, te pakaru rānei i ngā pāmahana i waenga i te 300°C me te 500°C, ka tukuna te paoa me ngā hau kino.
He rerekē, ko te taura MI he pūnaha whakamarumaru kore-waro, ā, ka taea te pupuri i te pumau o te hiko i raro i te mura tika i te 950°C pea. Ka taea te mahi tonu mō te neke atu i te 90 meneti, me te tutuki i ngā paerewa ātete ahi o te ao pēnei i te BS 6387 me te IEC 60331.
I taua wā anō, kāore ōna rauemi taura kore-mura e tahuna, e kore e whakaputa paoa, e kore hoki e tuku hau paitini, ā, ko te taura MI te otinga noa mō ngā rauemi taura ora ahi e whakamahia whānuitia ana i roto i ngā pūnaha hiko ohorere me ngā pūnaha tiaki ahi.
Ngā Painga me ngā Wero e Hangai ana ki ngā Rauemi
Mai i te tirohanga rauemi taura, he ātete ahi ā-roto te taura MI, he kaha kawe iahiko teitei, ā, he roa te ora mahi (ko te tikanga he 40–60 tau). He pai mō ngā taiao pāmahana teitei, haumākū, me te morearea.
Heoi, nā te nui o te whakamahinga o ngā rauemi parahi me te whakamarumaru konupora waikura (whakamarumaru MgO), he nui ake te utu o ngā rauemi katoa i ērā o ngā pūnaha taura tuku iho. Hei tāpiri, ko te hanganga kore-waro katoa ka hua ake he pakari ake, ka nui ake ngā whakaritenga mō te tāutanga taura, te mahi piko, me ngā tukanga hiri whakamutunga.
Ka taea e ngā hoahoa taura MI ngāwari te whakapai ake i te mahi tāutanga, engari ka whakapiki ake hoki i te uauatanga o ngā rauemi me te hanga.
Ngā tono noa
Nā te pai o te mahi a te rauemi taura ātete ahi, e whakamahia whānuitia ana te taura MI i roto i ngā pūnaha tiaki ahi o ngā whare teitei, ngā hanganga tereina, ngā whare tūmatanui nui, me ngā taiao hinu-matū he nui te pāmahana me ngā tūponotanga mura.
I roto i ēnei tono, mā te mahi pumau o tana pūnaha rauemi taura ka whakarite kia mau tonu te tuku hiko i raro i te ahi, i ngā āhuatanga tino kino rānei, ka waiho hei otinga tino nui mō ngā pūnaha hiko kawenga nui.
Whakamutunga: Ngā Auahatanga o te Whanaketanga Rauemi Taura
Mai i te tirohanga o ngā au whanaketanga rauemi taura, ko te taura MI he nekehanga nui mai i ngā rauemi whakamarumaru waro ki ngā rauemi whakamarumaru kore-waro.
Mō ngā kaiwhakarato rauemi taura, ko ngā āheinga ki te whakahaere i te parakore, te tohatoha rahi matūriki, te ātete ki te makuku, me ngā āhuatanga rere o te konupora waikura (whakamātao MgO), tae atu ki te tuku pumau o te ara iahiko parahi me ngā rauemi hipoki parahi, koinei ngā mea matua hei whakataetae i roto i te mākete rauemi taura ātete ahi kounga teitei.
Kei te arotahi tonu mātou, ā, kei te whakarato tonu i ngā otinga rauemi taura e pā ana, me te tautoko i ngā kiritaki i roto i te tono o te taura MI me ētahi atu pūnaha taura ātete ahi mahi teitei.
