ʻO nā uwea a me nā kaula he ʻāpana koʻikoʻi o ka ʻōnaehana mana a hoʻohana ʻia e hoʻouna i ka ikehu uila a me nā hōʻailona. Ma muli o ke kaiapuni hoʻohana a me ka hiʻohiʻona noi, nui nā ʻano uea a me ke kaula. Aia nā uwea keleawe ʻole, nā uwea mana, nā kaula i hoʻopaʻa ʻia ma luna, nā kaula hoʻomalu, nā uwea lole a me nā kaula kūikawā a pēlā aku.
Ma waho aʻe o nā ʻano uea maʻamau a me nā ʻano uea ma luna, aia kekahi uea kūikawā a me ke kaula, e like me ke uea wela wela a me ke kaula, ka uea a me ka uwea corrosion, uea a me ke kaula. Loaʻa i kēia mau uea a me nā kaula i nā waiwai kūikawā a me nā hoʻohana, kūpono no nā hiʻohiʻona noi a me nā ʻoihana.
I ka pōkole, e like me nā kaiapuni hoʻohana like ʻole a me nā hiʻohiʻona noiʻi, 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 ka waiwai pilikino, no laila e hoʻolohe i ke koho ʻana i nā hōʻailona maʻamau a me ka uea maikaʻi a me ke kaula i ka hana o ka hoʻohana. Hōʻike kēia ma lalo nei i kekahi mau ʻano uea maʻamau a me nā ʻano ʻano. Manaʻolana e kōkua iā ʻoe e hoʻomaopopo maikaʻi i ke ʻano o ke kumu hoʻohālike.
ʻO ke ʻano mua o ka uea a me ke kaula: uea keleawe ʻole
E pili ana nā huahana uea olohelohe a me nā mea ho'okele waiwai i ka uea conductive me ka ho'oku'u 'ole a me ka pu'u, 'o ka mea nui me ka uea ho'okahi wale, uea pa'a 'ole a me nā mo'olelo 'ekolu o nā huahana.
Uea alumini keleawe hoʻokahi: me ka uea keleawe palupalu, uea keleawe paʻakikī, uea alumini palupalu, uea alumini paʻakikī. Hoʻohana nui ʻia e like me ke ʻano o nā uea a me nā huahana semi-huahana, kahi liʻiliʻi o ka uea kamaʻilio a me ka hana ʻana i nā mea hana kaʻa.
Ua hoʻopaʻa ʻia ʻole: me ke kaula keleawe paʻa paʻa (TJ), uea alumini paʻa (LJ), uea alumini alumini (LHAJ), ke kila kila alumini stranded wire (LGJ) i hoʻohana nui ʻia no ka hoʻopili ʻana i nā mea uila a me nā mea uila a i ʻole nā ʻāpana.
ʻO ke ʻano ʻelua o ka uea a me ke kaula: ke kaula uila
ʻO ke kaula uila ma ka iwi kuamoʻo o ka ʻōnaehana mana no ka hoʻouna ʻana a me ka hāʻawi ʻana i nā huahana uila mana kiʻekiʻe, me ka 1 ~ 330KV a ma luna o nā pae uila like ʻole, nā ʻano uila mana insulation.
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, 3, 2, 5, 2, 1, 2 3+1, 3+2.
Hoʻokaʻawale ʻia nā kaula uila i nā kaula haʻahaʻa haʻahaʻa, nā kaula uila uila, nā kaula uila kiʻekiʻe a pēlā aku. E like me nā kūlana insulation ua māhele ʻia i nā kaula i hoʻopaʻa ʻia i ka plastic, nā kaula i hoʻopaʻa ʻia i ka lāʻau, nā kaula insulated mineral a pēlā aku.
ʻO ke kolu o ke ʻano uea a me ke kaula: overhead insulated cable
He mea maʻamau nō hoʻi ka uwea overhead, ʻike ʻia ʻo ia me ka ʻaʻahu ʻole. Nui ka poʻe i ʻekolu kuhi hewa e pili ana i kēia mau kaula. ʻO ka mea mua, ʻaʻole wale nā mea hoʻokele alumini wale nō, akā nā mea hoʻokele keleawe (JKYJ, JKV) a me nā alumini alumini (JKLHYJ). I kēia manawa, aia nā kaula kila alumini i hoʻopaʻa ʻia ma luna o ke poʻo (JKLGY). ʻO ka lua, ʻaʻole ia he kumu hoʻokahi wale nō, ʻo ka mea maʻamau ka mea maʻamau hoʻokahi, akā hiki ke haku ʻia i kekahi mau conductors. ʻO ke kolu, ʻo 35KV ka pae uila o ke kaula ma luna, ʻaʻole ʻo 1KV a me 10KV wale nō.
ʻO ke ʻano ʻehā o ka uea a me ke kaula: control cable
ʻO ke ʻano o kēia ʻano o ke kaula uila a me ke kaula mana like, ua ʻike ʻia e ke keleawe wale nō, ʻaʻohe alumini core cable, liʻiliʻi ka ʻāpana koʻikoʻi, ʻoi aku ka nui o nā cores, e like me 24 * 1.5, 30 * 2.5 etc.
He kūpono no ka AC helu volta 450/750V a ma lalo, nā mana mana, substations, mines, petrochemical ʻoihana a me nā mana kū hoʻokahi a i ʻole ka mana o ka ʻāpana. I mea e hoʻomaikaʻi ai i ka hiki o ke kaula hōʻailona hoʻomalu e pale aku i ka hoʻopili ʻana i loko a me waho, ua hoʻohana nui ʻia ka papa pale.
ʻO nā hiʻohiʻona maʻamau ʻo KVV, KYJV, KYJV22, KVV22, KVVP. ʻO ke ʻano o ke ʻano hoʻohālike: "K" papa hoʻomalu uea, "V"PVChoʻokaʻawale, "YJ"polyethylene i hoʻopaʻa ʻiaka hoʻokuʻu ʻana, "V" PVC sheath, "P" keleawe uea pale.
No ka papa pale, ʻo ka KVVP maʻamau he pale uea keleawe, inā he pale keleawe ia, ua hōʻike ʻia ʻo ia ʻo KVVP2, inā he alumini-plastic composite tape pale, ʻo ia ka KVVP3.
ʻO ke ʻano ʻelima o ka uea a me ke kaula: Hale Wiring Cable
Hoʻohana nui ʻia i nā keʻena ʻohana a me ka hāʻawi ʻana, a ʻo ka uea BV i ʻōlelo pinepine ʻia no nā uea lole. ʻO nā hiʻohiʻona he BV, BLV, BVR, RVV, RVVP, BVVB a pēlā aku.
Ma ka hōʻike hoʻohālike o ka uea a me ke kaula, ʻike pinepine ʻia ʻo B, a ʻo nā wahi like ʻole e hōʻike ana i nā manaʻo like ʻole.
No ka laʻana, ʻo BVVB, ʻo ka hoʻomaka ʻana o ka B ka manaʻo o ka uea, ʻo ia ka hōʻike ʻana i ka hoʻokaʻawale noi ʻana o ke kaula, e like me ke ʻano o JK ma luna o ke kaula, ʻo K ke ʻano o ke kaula mana. ʻO ka B ma ka hopena e hōʻike ana i ke ʻano pālahalaha, kahi koi kūikawā hou no ke kaula. ʻO ke ʻano o ka BVVB ʻo ia: ke kumu keleawe polyvinyl chloride insulated polyvinyl chloride sheathed flat cable.
ʻO ke ʻano ʻeono o ka uea a me ke kaula: Kāleka kūikawā
ʻO nā kaula kūikawā he mau uwea me nā hana kūikawā, ka mea nui me nā kaula pale ahi (ZR), nā kaula halogen-free haʻahaʻa (WDZ), nā kaula pale ahi (NH), nā kaula pahū (FB), nā kaulaʻiole a me nā kaula termite-proof (FS), nā kaula pale wai (ZS), a me nā mea'ē aʻe.
Ke hālāwai ka laina i ke ahi, hiki i ke kaula ke puhi wale ma lalo o ka hana o ka lapalapa o waho, liʻiliʻi ka nui o ka uahi, a he liʻiliʻi loa ke kinoea ʻino (halogen) i ka uahi.
Ke nalo ka lapalapa o waho, hiki i ke kaula ke pio iā ia iho, no laila e hoʻemi ʻia ke ahi i ke kino o ke kanaka a me ka pōʻino waiwai. No laila, hoʻohana nui ʻia kēia ʻano kelepona i ka petrochemical, ka mana uila, ka metallurgy, nā hale kiʻekiʻe a me nā wahi nui a me nā wahi koʻikoʻi.
Kālepa Refractory (NH): kūpono loa no ka mana koʻikoʻi a me nā ʻōnaehana mana. Aia ka laina i ke ahi, hiki i ke kaula pale ahi ke pale aku i ka wela kiʻekiʻe o 750 ~ 800 ° C no ka ʻoi aku o 90 mau minuke e hōʻoia i ka lawe ʻana i ka mana palekana e lanakila ai i ka hakakā ahi a me ka manawa hōʻemi pōʻino.
I mua o nā hanana kūikawā, loaʻa mau nā huahana hou, e like me nā kaula pale ahi, nā kaula pale ahi, nā kaula halogen haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa.
