I-Mineral Insulated Cable (MICC noma ikhebula le-MI), njengohlobo olukhethekile lwekhebula, isetshenziswa kabanzi kuzo zonke izigaba zokuphila ngenxa yokumelana nomlilo okuhle kakhulu, ukumelana nokugqwala kanye nokuzinza kokudlulisela. Leli phepha lizokwethula ukwakheka, izici, izinkambu zokufaka isicelo, isimo semakethe kanye nethuba lokuthuthukiswa kwekhebula le-mineral insulated ngokuningiliziwe.
1. Isakhiwo nezici
Ikhebula le-mineral insulated ikakhulukazi lakhiwe ngocingo lwe-copper conductor core, i-magnesium oxide powder insulation layer kanye nesheath yethusi (noma i-aluminium sheath). Phakathi kwazo, i-copper conductor core wire isetshenziswa njengendawo yokudlulisela yamanje, futhi i-magnesium oxide powder isetshenziswa njenge-inorganic insulating material ukuze ihlukanise umqhubi kanye ne-sheath ukuze kuqinisekiswe ukusebenza kukagesi nokuphepha kwekhebula. Ungqimba olungaphandle lungakhethwa ngokuvumelana nezidingo zomkhono ovikelayo ofanele, ukuze kuthuthukiswe ukuvikelwa kwekhebula.
Izici zekhebula le-mineral insulated zibonakala kakhulu kulezi zici ezilandelayo:
(1) Ukumelana nomlilo okuphakeme: Ngenxa yokuthi ungqimba olufakwa ngaphakathi lwakhiwe ngezinto ezimbiwa phansi ze-inorganic mineral njenge-magnesium oxide, izintambo ezivalwe ngamaminerali zisengagcina ukusebenza kahle kokufakwa emazingeni okushisa aphezulu futhi zivikele umlilo ngempumelelo. I-sheath yayo yethusi izoncibilika ku-1083 ° C, futhi ukufakwa kwamaminerali kungamelana namazinga okushisa angaphezu kuka-1000 ° C.
(2) Ukumelana nokugqwala okuphezulu: ishubhu yethusi engenamthungo noma ishubhu le-aluminium njengempahla ye-sheath, ukuze ikhebula le-mineral insulated likwazi ukumelana nokugqwala okuphezulu, lingasetshenziswa ezindaweni ezinokhahlo isikhathi eside.
(3) Ukuzinza kokudluliswa okuphezulu: Ikhebula le-mineral insulated lisebenza kahle kakhulu, lilungele ibanga elide, ukudluliswa kwedatha ngesivinini esikhulu kanye nokudluliswa kwamandla kagesi aphezulu kanye nezinye izimo. Inomthamo omkhulu wokuthwala wamanje, isilinganiso esiphakeme samaphutha esekethe emfishane, futhi ingadlulisela amandla aphezulu ngezinga lokushisa elifanayo.
(4) Impilo ende yesevisi: ngenxa yokumelana nomlilo, ukumelana nokugqwala nezinye izici, impilo yesevisi yezintambo ezivalwe ngamaminerali yinde kakhulu, ngokuvamile ifinyelela eminyakeni engaba ngu-70.
2. Inkambu yezicelo
Izintambo ezifakwe amaminerali asetshenziswa kabanzi kuyo yonke imikhakha yempilo, ikakhulukazi okuhlanganisa:
(1) Izakhiwo eziphakeme kakhulu: ezisetshenziselwa ukukhanyisa okuvamile, ukukhanyisa izimo eziphuthumayo, i-alamu yomlilo, izintambo zikagesi womlilo, njll., ukuze kuqinisekiswe ukuthi ugesi ojwayelekile usengahlinzekwa ezimeni eziphuthumayo.
(2) Imboni ye-Petrochemical: Ezindaweni ezingase zibe yingozi ukuqhuma, ukumelana nomlilo okuphezulu kanye nokungagqwala kwamakhebuli afakwe ku-mineral insulated kuzenza zibe zinhle.
(3) Ezokuthutha: izikhumulo zezindiza, imigudu engaphansi komhlaba, imikhumbi kanye nezinye izindawo, izintambo ezifakwe amaminerali zisetshenziselwa ukukhanyisa izimo eziphuthumayo, izinhlelo zokuqapha umlilo, imigqa yokukhipha umoya, njll, ukuqinisekisa ukusebenza okuphephile kwezikhungo zethrafikhi.
(4) Izinsiza ezibalulekile: njengezibhedlela, izikhungo zedatha, amagumbi okulawula umlilo, njll., zinezidingo eziphezulu zokuzinza kokudluliswa kwamandla nokusebenza komlilo, futhi izintambo ezifakwe amaminerali zibalulekile.
(5) Imvelo ekhethekile: umhubhe, indawo engaphansi kanye nokunye okuvaliwe, okunomswakama, izinga lokushisa eliphezulu, ukumelana nomlilo wekhebula, izidingo zokumelana nokugqwala ziphezulu, ikhebula le-mineral insulated lingahlangabezana nalezi zidingo.
3. Isimo semakethe kanye namathemba okuthuthukiswa
Ngokunaka okwandayo kokuphepha komlilo, isidingo semakethe samakhebuli afakwe amaminerali siyakhula. Ikakhulukazi kumaphrojekthi wamandla avuselelekayo afana nelanga nomoya, izintambo ezifakwe ngamaminerali zisetshenziswa kabanzi ngenxa yezakhiwo zazo ezimelana nomlilo. Kubikezelwa ukuthi ngo-2029, usayizi wemakethe yekhebula le-mineral insulated emhlabeni wonke uzofinyelela ku-$2.87 billion, ngesilinganiso sokukhula sonyaka esihlanganisiwe (CAGR) esingu-4.9%.
Emakethe yasekhaya, ngokuqaliswa kwamazinga afana ne-GB/T50016, ukusetshenziswa kwezintambo ezifakwe amaminerali emigqeni yomlilo bekuyimpoqo, okuye kwakhuthaza ukuthuthukiswa kwemakethe. Njengamanje, izintambo zamandla afakwe amaminerali afakwe engxenyeni enkulu yemakethe, futhi izintambo zokufudumeza ezifakwe ngamaminerali nazo ziyandisa kancane kancane ububanzi bokusebenza kwazo.
4.Isiphetho
Ikhebula le-mineral insulated lidlala indima ebalulekile kuyo yonke imikhakha yempilo ngenxa yokumelana nomlilo okuhle kakhulu, ukumelana nokugqwala kanye nokuzinza kokudlulisela. Ngokuthuthukiswa okuqhubekayo kwezidingo zokuphepha komlilo kanye nokuthuthukiswa okusheshayo kwamaphrojekthi wamandla avuselelekayo, ithemba lemakethe lezintambo ezifakwe emanzini amaminerali libanzi. Kodwa-ke, izindleko zayo eziphezulu kanye nezidingo zokufakwa nazo zidinga ukucatshangelwa ekukhetheni nasekusetshenzisweni. Ekuthuthukisweni okuzayo, izintambo ezifakwe amaminerali zizoqhubeka zidlala izinzuzo zazo eziyingqayizivele zokudluliselwa kwamandla nokuphepha komlilo kuzo zonke izigaba zokuphila.
