Hoʻolālā Kūkulu o nā Uea Pale Ahi Hou

I ka hoʻolālā ʻōnaehana o nā mea houpale ahinā kaula,polyethylene i hoʻopili ʻia (XLPE) i hoʻopaʻa ʻiaHoʻohana nui ʻia nā kaula. Hōʻike lākou i ka hana uila maikaʻi loa, nā waiwai mechanical, a me ke kūpaʻa o ke kaiapuni. Hōʻike ʻia e nā mahana hana kiʻekiʻe, nā mana hoʻoili nui, ke kau palena ʻole, a me ke kau ʻana a me ka mālama pono ʻana, hōʻike lākou i ke kuhikuhi hoʻomohala o nā kaula hou.

1. Hoʻolālā Alakaʻi Uea

ʻAno a me nā ʻano o ke alakaʻi: Hoʻohana ke ʻano alakaʻi i kahi ʻano lua o ke ʻano o ke alakaʻi paʻa e like me ka peʻahi, me ka hoʻohana ʻana i kahi ʻano kaula maʻamau (1+6+12+18+24). I ke kaula maʻamau, aia ka papa waena i hoʻokahi uea, ʻeono uea o ka papa ʻelua, a ʻokoʻa nā papa pili ma hope e ʻeono uea. ʻO ka papa waho loa he kaula hema, aʻo nā papa pili ʻē aʻe he kaula ma ke ʻano ʻē. He poepoe nā uea a like ke anawaena, e hōʻoiaʻiʻo ana i ke kūpaʻa i loko o kēia ʻano kaula. ʻAno paʻa: Ma o ke kāpili ʻana, lilo ka ʻili o ke alakaʻi i laumania, e pale ana i ka nui o nā kahua uila. I ka manawa like, pale ia i nā mea semi-conductive mai ke komo ʻana i loko o ke kumu uea i ka wā o ka insulation extrusion, e pale pono ana i ke komo ʻana o ka makū a me ka hōʻoia ʻana i kahi kekelē o ka maʻalahi. Loaʻa i nā alakaʻi kaula maikaʻi ka maʻalahi, ka hilinaʻi, a me ka ikaika kiʻekiʻe.

2. Papa Hoʻokaʻawale UeaHoʻolālā

ʻO ke kuleana o ka papa insulation ka hōʻoia ʻana i ka hana uila o ke kaula a pale i ke kahe ʻana o ke au ma ke alakaʻi mai ka leaka ʻana i waho. Hoʻohana ʻia kahi ʻano extrusion, meMea XLPEi koho ʻia no ka insulation. Hāʻawi ʻo XLPE i ka hana ʻoi aku ka maikaʻi ma mua o ka polyethylene, nona nā waiwai insulation uila maikaʻi loa, i hōʻike ʻia e nā dielectric constants liʻiliʻi (ε) a me ka dielectric loss tangent haʻahaʻa (tgδ). He mea insulation alapine kiʻekiʻe kūpono ia. ʻO kona coefficient pale volume a me ka ikaika o ke kahua breakdown e mau ana ka loli ʻole ma hope o ʻehiku mau lā o ka hoʻokomo ʻana i loko o ka wai. No laila, hoʻohana nui ʻia ia i ka insulation uwea. Eia nō naʻe, he haʻahaʻa kona wahi heheʻe. Ke hoʻohana ʻia i nā kaula, hiki i nā hewa overcurrent a i ʻole nā ​​​​pōkole pōkole ke kumu o ka piʻi ʻana o ka mahana, e alakaʻi ana i ka palupalu a me ka deformation o ka polyethylene, e hopena ana i ka hōʻino ʻana o ka insulation. No ka mālama ʻana i nā pono o ka polyethylene, hana ia i ka cross-linking, e hoʻoikaika ana i kona pale wela a me ke kūʻē ʻana i ka haki ʻana o ke kaiapuni, e hana ana i ka mea polyethylene cross-linked i mea insulation kūpono.

3. Hoʻolālā Hoʻopili a me ka ʻUhi ʻana i ke Uea

ʻO ke kumu o ke kaula ʻana a me ka ʻōwili ʻana i ke kaula, ʻo ia ke pale i ka insulation, e hōʻoia i kahi kumu kaula paʻa, a pale i ka insulation wehe a me nā mea hoʻopihapiha, e hōʻoia ana i ka poepoe o ke kumu.kāʻei ʻōwili pale ahihāʻawi i kekahi mau waiwai pale ahi.

Nā Mea Hana no ke Kau ʻana a me ka ʻUhi ʻana i ke Uea: He mea pale ahi ka mea ʻuhilole ulana ʻolekāʻei, me ka ikaika tensile a me kahi helu pale lapalapa ʻaʻole i emi iho ma mua o 55% helu oxygen. Hoʻohana ka mea hoʻopihapiha i nā kaula pepa inorganic flame-retardant (nā kaula mineral), he palupalu, me kahi helu oxygen ʻaʻole i emi iho ma mua o 30%. ʻO nā koi no ke kaula kaula a me ka ʻōwili ʻana e pili ana i ke koho ʻana i ka laulā o ke kāʻei ʻōwili e pili ana i ke anawaena kumu a me ke kihi o ke kāʻei, a me ka overlapping a i ʻole ka mamao o ka ʻōwili. ʻO ke kuhikuhi ʻōwili he lima hema. Pono nā kāʻei pale lapalapa kiʻekiʻe no nā kāʻei pale lapalapa. Pono ke kūpaʻa wela o ka mea hoʻopihapiha e kūlike me ka mahana hana o ke kaula, a ʻaʻole pono e launa pū kona ʻano me kamea uhi pale.Pono e wehe ʻia me ka ʻole o ka hōʻino ʻana i ke kumu insulation.
