Ko te taura honohono-whakawhiti he whakarāpopototanga mō te taura polyethylene honohono-whakawhiti (XL-PE) kua whakamātaotia. He pai ngā taura honohono-whakawhiti mō ngā raina tuku me te tohatoha me te ngaohiko ac auau mana tae atu ki te 500KV. I tēnei wā, ko te nuinga o ngā taura ngaohiko-teitei kua whakamātaotia e te polyethylene honohono-whakawhiti.
Ko ngā taura honohono-whiti e pā ana ki ngā taura he mea hanga te whakamarumaru mai i ngā rauemi honohono-whiti. Ko te rauemi e whakamahia whānuitia ana ko te polyethylene honohono-whiti (XLPE). Ko te tukanga honohono-whiti ko te hanga i te hanganga ngota ngota raina o te polyethylene (PE) mā te huarahi tukatuka motuhake hei hanga i te āhua o te hanganga raina reticulated polyethylene honohono-whiti. Nō reira, ka piki ake te pāmahana mahi roa e whakaaetia ana mai i te 70℃ ki te 90℃ (neke atu rānei), ā, ka piki ake te pāmahana e whakaaetia ana mō te ara-poto mai i te 140℃ ki te 250℃ (neke atu rānei), e tino whakapai ake ana i te mahi tuturu i raro i te kaupapa o te pupuri i tana mahi hiko tino pai.
He maha ngā painga o te XLPE. He maha ngā momo XLPE e tukuna ana e Wenchang hei whiriwhiri māu.
Pērā i te UL3265, UL3266, UL3167, UL3173, UL3182, UL3194, UL3195, UL3196, UL3199, UL3236 me ētahi atu.
(1) He tino pai ngā āhuatanga ā-pūkaha me ā-tinana, he pai te ātete ki te pakaru i te ahotea taiao, he pai te ātete ki te kakahu, he nui ake te kaha ki te tu atu i te ahotea ā-pūkaha kukū i te PVC me te PE.
(2) Ātete ki ngā momo whakarewa matū, pumau ki ngā momo pāpāho waikura huri noa.
(3) He iti ake te diameter o waho o te waea polyolefin kua whakamātaohia ki te hihi i tērā o te waea polyvinyl chloride katoa me te wāhanga whakatakotoranga ōrite, ka taea te whakaiti i te diameter o te paipa e whakamahia ana i roto i te hanganga miro paipa, te mau rānei i ngā waea maha atu i raro i te āhua diameter paipa ōrite, ā, ka whakaiti i te utu tāutanga hanga.
(4) He mama ake te waea polyolefin honohono-iraira i te waea PVC, he pai ake te tāutanga me te kawe, ka whakaiti i te kaha o te mahi me te utu kawe.
(5) Ka taea e te pāmahana teitei rawa o te waea honohono whakawhiti kua whitia te eke ki te 125℃ i te wā e whakamahia ana mō te wā roa, ā, he nui ake te kaha kawe i tērā o te waea PVC kua whitia.
(6) Kāore e tukuna he hau waikura, he hau paitini rānei i te wā e tahuna ana, ā, e kore e puta he kino tuarua. He momo hua tiaki taiao hou tēnei e rite ana ki ngā whakaritenga haumaru ahi o ēnei rā.
(7) He pai te mahi hiko, he nui ake te ātete ki te whakamahana i te taura PVC, ā, he iti rawa te koki ngaronga waenga o te pātata, kāore e rerekē i te huringa o te pāmahana.
