ʻO YJY a me YJV nā huahana uea a me nā kelepona i hoʻohana mau ʻia i ka ʻenekinia a me ke kūkulu ʻana, a hoʻohana ʻia no nā laina hoʻoili mana.Eia naʻe, ʻokoʻa nā hiʻohiʻona a me nā kikoʻī o nā mea ʻelua.Aia kekahi ʻokoʻa i ka waiwai a me ke kumukūʻai o ka pū?Ma lalo, e kaʻana like ka mea hoʻoponopono iā ʻoe i nā ʻokoʻa ma waena o YJY a me YJV.
Kaula YJY
Hoʻolauna
YJY——XLPE insulated polyethylene sheathed power cable, ʻo ke kaula mana i hana ʻia me ka polyethylene material he mau mea thermomechanical maikaʻi loa, ʻoi aku ka maikaʻi o ka hana ʻana o ka lapalapa ahi, a ʻoi aku ka maikaʻi o ka ampacity ma mua o nā kaula mana YJV maʻamau, a hoʻomaikaʻi pū i ka hana o ke kaula.hana uila a me nā hiʻohiʻona pale wela.
YJ—— polyethylene pili kea
Y——polythylene
Palapala noi
Hiki ke waiho ʻia i loko o ka hale, i loko o nā paipu a i ʻole ka lepo palupalu, inā ʻaʻole hiki ke kū i ka ʻāʻī a me ke kaomi;hiki ke hoʻohana ʻia i nā ʻoihana hoʻoili a i ʻole nā mea hana ʻoihana me ka pae volta o 1-1000kV a ma luna, e like me nā kikowaena mana, nā laina kukui o ke kūlanakauhale, a me ka mana kiʻekiʻe-voltage tower transmission, ka mana o lalo a me nā wahi ʻē aʻe.
Nā hiʻohiʻona
ʻO nā kaula YJY he maʻalahi i ka hoʻolālā, haʻahaʻa i ka paʻakikī a me ka palupalu, a maʻalahi hoʻi no ka lawe ʻana, akā ʻaʻole lākou compressive, no laila e mālama pono i ka wā e mālama ai a lawe ʻia paha.
Pōmaikaʻi
E like me nā koi o kekahi mau mea hoʻohana, hiki i ka YJY Power Cable ke hana i nā kaula i hoʻohana ʻia i nā manawa koi nui e like me ka flame-retardant (ZB), ahi-resistant (NH), a me ka uahi haʻahaʻa a me ka haʻahaʻa-halogen (WDZ).Loaʻa i kēia mau kaula ka palekana kiʻekiʻe a me ka hoʻokō ʻana, a he mea pili kaiapuni.Hana ikaika.
Uea YJV
Ua kapa ʻia ʻo YJV uea i ka polyethylene insulated PVC sheathed power cable.Ma waena o lākou, hōʻike ʻo YJ i ka insulation polyethylene i hoʻopili ʻia, a ʻo V ke ʻano o ka polyvinyl chloride sheath.Ma waena o lākou, hōʻike pū ʻo YJV i kahi kaula keleawe keleawe, aʻo YJLV ke hōʻike nei i kahi kaula kumu alumini.
NO.1 kau ala
1. YJV, YJLV keleawe (aluminum) kumu XLPE insulated PVC sheath ua waiho i loko o ka hale, i loko o ka auwaha a me ka paipu, a hiki no hoi ke kanu ia i loko o ka lepo lepo, akā, hiki ole ke hoʻomanawanui a me ka ikaika mechanical waho.
2. YJV22, YJLV22 keleawe (aluminum) core XLPE insulated kila lipine pale kaua PVC sheathed mana uwea ua waiho ia ma lalo o ka lepo a hiki ke pale aku i waho mechanical ikaika, akā, hiki ole ke pale i ka nui tensile ikaika.
NO.2 E hoʻohana i nā ʻano
ʻO 90°C ka mahana i helu ʻia o ka mea hoʻokele kelepona.I ka wā pōkole (ʻaʻole ʻoi aku ka lōʻihi o ka lōʻihi ma mua o 5S), ʻaʻole ʻoi aku ka nui o ka mahana o ka mea lawe kelepona ma mua o 250°C.ʻAʻole pono ka haʻahaʻa haʻahaʻa ma mua o 0 ° C ka mahana o ke kau ʻana i ke kaula.ʻO ka radius kulou ʻae ʻia i ka wā e waiho ana: ʻaʻole emi ke kaula hoʻokahi ma mua o 15 mau manawa o ke anawaena o waho o ke kaula;ʻaʻole emi ka uea multi-core ma mua o 10 mau manawa o ke anawaena o waho o ke kaula.
NO.3 Ke ala koho
Hōʻike ʻia ka volta helu o ke kaula e ka U0/U(Um): ʻO U0 ka mana i helu ʻia ma waena o ka conductor no ka hoʻolālā ʻana o ke kaula a me ka lepo a i ʻole ka pale metala, ʻo U ʻo ia ka helu mana alapine uila ma waena o nā conductors no ka hoʻolālā uea, Um ʻO ke kumukūʻai kiʻekiʻe loa o ka volta ʻōnaehana kiʻekiʻe loa i hiki i ka mea hana ke pale aku.E like me ke ʻano o ka waiho ʻana a me ka ukana o ke kaula, ua hoʻolālā ʻia a koho ʻia nā kikoʻī a me nā hiʻohiʻona o ke kaula.
ʻO ke ʻano pale kaua kūpono ʻole no ka overhead, loko, tunnel, cable auwaha a me nā manawa ʻē aʻe, a ʻaʻole hiki ke hoʻomanawanui i ka ikaika mechanical o waho.Hiki ke kanu pololei ʻia ke ʻano pale kaua i ka lepo koe wale nō nā kūlana kūpono o ke ʻano pale kaua.Hiki ke hoʻopaʻa i kekahi mana mechanical waho.ʻAʻole ʻae ʻia nā kaula hoʻokahi-core e waiho i loko o nā paipu e hoʻoulu ai i ka magnetism.Pono e koho ʻia nā ʻano uwea kūikawā no nā mea hiki ke puhi ʻia, pahū, hoʻoheheʻe kemika, wela kiʻekiʻe, wela haʻahaʻa a me nā manawa ʻē aʻe.
ʻO ka ʻokoʻa
ʻO ka mea mua, ʻoi aku ka maikaʻi o ka YJY i ka wai a me ka haʻahaʻa haʻahaʻa haʻahaʻa ma mua o YJV, a ʻoi aku ka maikaʻi o YJV ma mua o ka YJY.ʻO ka wela o ka hana ʻana o ka YJY cross-linked polyethylene insulated power cable conductor he 90 ° C, ʻoi aku ka kiʻekiʻe ma mua o ka polyethylene insulated cables, no laila e hoʻonui hou ʻia ka hiki ke lawe i kēia manawa.ʻO ka mahana hana i helu ʻia ʻoi loa o ka conductor ʻo 90 ° C, a ʻo ka mahana pōkole pōkole loa o ka conductor ʻaʻole ʻoi aku ma mua o 250 ° C, a ʻo ka manawa lōʻihi ʻaʻole e ʻoi aku ma mua o 5 kekona.Loaʻa i ke kaula YJV nā waiwai thermomechanical maikaʻi loa, nā waiwai uila maikaʻi a me ke kūpaʻa corrosion kemika.Loaʻa iā ia nā pōmaikaʻi o ka hoʻolālā maʻalahi, ka paona māmā, a ʻaʻohe palena i ke kiʻekiʻe o ke kau ʻana.He uwea hou ia i hoʻohana nui ʻia i kēia manawa i loko o nā pahu mana o ke kūlanakauhale, nā mines a me nā hale hana.
ʻO ka lua, ʻo ka puʻu o YJV he PVC, kahi kaula halogen;ʻO ka uhi o YJY he polyethylene, he kaula halogen-ʻole.
ʻO ka mea hope loa, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke kelepona YJY.ʻO YJY kahi kaula keleawe i hoʻopili ʻia i ka polyethylene insulated polyethylene sheathed power cable, a ʻo YJV he copper core cross-linked polyethylene insulated polyvinyl chloride sheathed power cable.Eia nō naʻe, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka mea XLPE ma mua o ka mea PVC, e hopena i ke kumukūʻai kiʻekiʻe o YJY.
