He ʻāpana koʻikoʻi nā uea a me nā kaula o ka ʻōnaehana mana a hoʻohana ʻia e hoʻoili i ka ikehu uila a me nā hōʻailona. Ma muli o ke kaiapuni hoʻohana a me ke ʻano noi, nui nā ʻano uea a me ke kaula. Aia nā uea keleawe ʻōlohelohe, nā uea mana, nā uea insulated overhead, nā uea hoʻomalu, nā uea lole a me nā uea kūikawā a pēlā aku.
Ma waho aʻe o nā ʻano uea a me ke kaula maʻamau i luna nei, aia kekahi mau uea a me ke kaula kūikawā, e like me ke uea a me ke kaula wela kiʻekiʻe, ke uea a me ke kaula kū i ka pala, ke uea a me ke kaula kū i ke kapa komo. Loaʻa i kēia mau uea a me nā kaula nā waiwai a me nā hoʻohana kūikawā, kūpono no nā hiʻohiʻona noi a me nā ʻoihana kikoʻī.
I ka pōkole, e like me nā ʻano hoʻohana like ʻole a me nā hiʻohiʻona noi, ʻo ke koho ʻana i ke ʻano kūpono o ka uea a me ke kaula hiki ke hōʻoia i ka hana palekana a paʻa o ka ʻōnaehana mana. I ka manawa like, pili pono ka maikaʻi a me ka hana palekana o ka uea a me ke kaula i ka palekana o nā waiwai pilikino, no laila e hoʻolohe i ke koho ʻana o nā lama maʻamau a me ka uea a me ke kaula hilinaʻi i ke kaʻina hana o ka hoʻohana ʻana. Hōʻike kēia ma lalo nei i kekahi mau ʻano uea a me ke kaula maʻamau a me ko lākou mau ʻano. Manaʻolana e kōkua iā ʻoe e hoʻomaopopo maikaʻi i ke ʻano o ke kumu hoʻohālike kikoʻī.
ʻO ke ʻano mua o ka uea a me ke kaula: uea keleawe ʻōlohelohe
ʻO nā huahana uea ʻōlohelohe a me nā huahana alakaʻi ʻōlohelohe e pili ana i ka uea conductive me ka ʻole o ka insulation a me ka sheath, ʻo ia hoʻi ka uea hoʻokahi ʻōlohelohe, ka uea stranded ʻōlohelohe a me ke ʻano ʻekolu o nā huahana.
Uea keleawe alumini hoʻokahi: me ke keleawe palupalu hoʻokahi uea, keleawe paʻakikī hoʻokahi uea, alumini palupalu hoʻokahi uea, alumini paʻakikī hoʻokahi uea. Hoʻohana nui ʻia e like me nā ʻano huahana uea a me nā uwea semi-product, kahi liʻiliʻi o ka uea kamaʻilio a me nā mīkini hana.
Uea kaula ʻōlohelohe: me ke keleawe paʻakikī (TJ), ka alumini paʻakikī (LJ), ka alumini me ka huila alumini (LHAJ), a me ke kila kila alumini (LGJ) e hoʻohana nui ʻia no ka hoʻopili ʻana i nā lako uila a me nā mīkini uila a i ʻole nā ʻāpana, ʻo nā kikoʻī o nā ʻano uea kaula like ʻole ma luna nei mai 1.0-300mm².
ʻO ka lua o ke ʻano o ka uea a me ke kaula: ke kaula mana
ʻO ke kaula mana ma ke kuamoʻo o ka ʻōnaehana mana no ka hoʻoili ʻana a me ka hāʻawi ʻana i nā huahana kaula mana kiʻekiʻe, me 1 ~ 330KV a ma luna o nā pae voltage like ʻole, nā kaula mana insulation like ʻole.
ʻO ka ʻāpana he 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm², a ʻo ka helu kumu he 1, 2, 3, 4, 5, 3+1, 3+2.
Ua māhele ʻia nā kaula mana i nā kaula uila haʻahaʻa, nā kaula uila waena, nā kaula uila kiʻekiʻe a pēlā aku. Wahi a nā kūlana insulation, ua māhele ʻia i nā kaula uila plastik, nā kaula uila rapa, nā kaula uila mineral a pēlā aku.
ʻO ke kolu o ke ʻano o ka uea a me ke kaula: ke kaula i hoʻopaʻa ʻia ma luna
He mea maʻamau nō hoʻi ke kaula uila ma luna, ʻaʻohe ona ʻaʻahu. He nui ka poʻe i loaʻa i ʻekolu mau manaʻo kuhihewa e pili ana i kēia mau kaula. ʻO ka mea mua, ʻaʻole wale nā mea alakaʻi he alumini, akā, he mau alakaʻi keleawe hoʻi (JKYJ, JKV) a me nā mea hoʻohui alumini (JKLHYJ). I kēia manawa, aia kekahi mau kaula uila alumini kila (JKLGY). ʻO ka lua, ʻaʻole ia he kumu hoʻokahi wale nō, ʻo ka mea maʻamau he kumu hoʻokahi wale nō, akā hiki ke hana ʻia me kekahi mau alakaʻi. ʻO ke kolu, ʻo ka pae voltage o ke kaula uila he 35KV a ma lalo, ʻaʻole wale 1KV a me 10KV.
ʻO ke ʻano ʻehā o ke uea a me ke kaula: ke kaula hoʻomalu
He like ke ʻano o kēia ʻano uwea a me ke kaula mana, ʻo ke ʻano o ia mea he keleawe wale nō, ʻaʻohe uwea alumini, he liʻiliʻi ka ʻāpana kea o ke alakaʻi, a ʻoi aku ka nui o nā ʻiʻo, e like me 24 * 1.5, 30 * 2.5, a pēlā aku.
He kūpono no ka uila AC i helu ʻia he 450/750V a ma lalo, nā kikowaena mana, nā kikowaena, nā mines, nā ʻoihana petrochemical a me nā lako hoʻokele kū hoʻokahi a i ʻole nā lako ʻāpana. I mea e hoʻomaikaʻi ai i ka hiki ke pale aku i ka hoʻopilikia kūloko a me waho o ke kaula hōʻailona hoʻokele, ua hoʻohana nui ʻia ka papa pale.
ʻO nā kumu hoʻohālike maʻamau ʻo KVV, KYJV, KYJV22, KVV22, KVVP. ʻO ke ʻano o ke kumu hoʻohālike: papa uwea hoʻomalu "K", "V"PVCka pale ʻana, "YJ"polyethylene i hoʻopili ʻiaka pale ʻana, ka ʻūpā PVC “V”, ka pale uea keleawe “P”.
No ka papa pale, ʻo ka KVVP maʻamau he pale uea keleawe, inā he pale ʻāpana keleawe ia, ua hōʻike ʻia ʻo ia ʻo KVVP2, inā he pale lipine hui alumini-plastic, ʻo ia ʻo KVVP3.
ʻO ke ʻano ʻelima o ka uea a me ke kaula: Uea Uea Hale
Hoʻohana nui ʻia i loko o nā keʻena hale a me nā keʻena hoʻolaha, a ʻo ka uea BV i ʻōlelo pinepine ʻia no nā uea lole. ʻO nā kumu hoʻohālike ʻo BV, BLV, BVR, RVV, RVVP, BVVB a pēlā aku.
I ke kumu hoʻohālike o ka uea a me ke kaula, ʻike pinepine ʻia ʻo B, a hōʻike nā wahi like ʻole i nā manaʻo like ʻole.
No ka laʻana, ʻo BVVB, ʻo ka hoʻomaka ʻana o ka B ke ʻano o ka uea, ʻo ia ke kuhikuhi i ka hoʻokaʻawale ʻana o ke kaula, e like me JK ke ʻano o ke kaula luna, ʻo K ke ʻano o ke kaula hoʻomalu. ʻO ka B ma ka hopena e hōʻike ana i ke ʻano pālahalaha, ʻo ia kekahi koi kūikawā no ke kaula. ʻO ke ʻano o BVVB: ke kaula pālahalaha i uhi ʻia me ka polyvinyl chloride i hoʻopaʻa ʻia me ke keleawe.
ʻO ke ono o ke ʻano o ka uea a me ke kaula: Uea kūikawā
ʻO nā kaula kūikawā he mau kaula me nā hana kūikawā, ʻo ia hoʻi nā kaula pale ahi (ZR), nā kaula halogen-free haʻahaʻa (WDZ), nā kaula pale ahi (NH), nā kaula pale pahū (FB), nā kaula pale ʻiole a me nā kaula pale anai (FS), nā kaula pale wai (ZS), a pēlā aku. ʻO ke kaula pale ahi (ZR), ke kaula halogen-free haʻahaʻa (WDZ): kūpono nui no nā ʻōnaehana mana a me ka hoʻokele koʻikoʻi.
Ke hālāwai ka laina me ke ahi, hiki i ke kaula ke puhi wale ma lalo o ka hana a ka lapalapa o waho, he liʻiliʻi ka nui o ka uahi, a he liʻiliʻi loa hoʻi ke kinoea ʻino (halogen) i loko o ka uahi.
Ke nalo aku ka lapalapa o waho, hiki i ke kaula ke kinai iā ia iho, i hiki ai ke hoʻemi ʻia ke ahi i ke kino kanaka a me ka pōʻino waiwai i ka liʻiliʻi loa. No laila, hoʻohana nui ʻia kēia ʻano kaula i ka petrochemical, ka mana uila, ka metallurgy, nā hale kiʻekiʻe a me nā wahi i noho nui ʻia a me nā wahi koʻikoʻi ʻē aʻe.
Uaea paʻa ʻole (NH): kūpono nui no nā ʻōnaehana mana a me ka mana koʻikoʻi. Ke ahi ka laina, hiki i ke uaea pale ahi ke kū i ka mahana kiʻekiʻe o 750 ~ 800 ° C no nā minuke he 90 a ʻoi e hōʻoia i ka hoʻoili mana palekana e lanakila ai i ka manawa pale ahi a me ka hōʻemi ʻana i ka pōʻino.
I ke alo o nā hanana kūikawā, loaʻa mau nā huahana hou, e like me nā kaula pale ahi, nā kaula pale ahi, nā kaula halogen haʻahaʻa-uahi ʻole/haʻahaʻa-uahi haʻahaʻa-halogen, nā kaula pale anai/pale ʻiole, nā kaula aila/anu/mahana/pale ʻaʻahu, nā kaula i hoʻopili ʻia i ka radiation, a pēlā aku.
