IiCables zeMineral Insulated: AbaGcileli boKhuseleko kunye noZinzo

I-Mineral Insulated Cable (i-MICC okanye i-MI cable), njengohlobo olukhethekileyo lwekhebula, lusetyenziswa ngokubanzi kuzo zonke iindlela zobomi ngenxa yokumelana nomlilo obalaseleyo, ukuxhathisa ukubola kunye nokuzinza kokudluliselwa. Eli phepha liza kwazisa ubume, iimpawu, imimandla yesicelo, ubume bemarike kunye nethemba lophuhliso lwentambo ye-mineral insulated cable.

1. Isakhiwo kunye neempawu

Intambo ye-mineral insulated ikakhulu yenziwe ngocingo olungundoqo lwecopper, i-magnesium oxide engumgubo wokugquma umaleko kunye neshethi yobhedu (okanye i-aluminiyam sheath). Phakathi kwabo, i-copper conductor core wire isetyenziswa njengendlela yokuhambisa yangoku, kwaye i-magnesium oxide powder isetyenziswa njenge-inorganic insulating material ukwahlula umqhubi kunye ne-sheath ukuqinisekisa ukusebenza kombane kunye nokhuseleko lwentambo. Uluhlu olungaphandle lunokukhethwa ngokweemfuno zemikhono efanelekileyo yokukhusela, ukuqhubela phambili ukunyusa ukukhuselwa kwentambo.

Iimpawu ze-mineral insulated cable zibonakaliswa ikakhulu kule miba ilandelayo:
(1) Ukumelana nomlilo okuphezulu: Ngenxa yokuba umaleko wokugquma owenziwe ngezinto zeminerali ezingaphiliyo ezifana ne-magnesium oxide, iintambo ezifakwe kwi-mineral insulated zisengagcina ukusebenza kakuhle kokugquma kumaqondo obushushu aphezulu kwaye zithintele ngokufanelekileyo umlilo. I-sheath yayo yobhedu iya kunyibilika kwi-1083 ° C, kwaye i-mineral insulation inokumelana nokushisa okuphezulu ngaphezu kwe-1000 ° C.
(2) Ukuxhathisa okuphezulu kwe-corrosion: ityhubhu yobhedu engenamthungo okanye ityhubhu ye-aluminium njengesixhobo se-sheath, ukuze ikhebula le-mineral insulated line-resistance resistant corrosion, linokusetyenziswa kwiindawo ezinzima ixesha elide.
(3) Ukuzinza okuphezulu kokuhanjiswa: Ikhebula le-Mineral insulated lisebenza kakuhle kakhulu, lilungele umgama omde, ukuhanjiswa kwedatha ngesantya esiphezulu kunye nokuhanjiswa kwamandla ombane aphezulu kunye nezinye iimeko. Inomthamo omkhulu wokuthwala wangoku, ukulinganisa impazamo ye-short-circuit ephezulu, kwaye inokudlulisa umsinga ophezulu kwiqondo lobushushu elifanayo.
(4) Ubomi benkonzo ende: ngenxa yokumelana nomlilo, ukuxhathisa ukubola kunye nezinye iimpawu, ubomi benkonzo yeentambo ezifakwe kwi-mineral insulated bude kakhulu, ngokuqhelekileyo ukuya kuthi ga kwiminyaka engama-70.

2. Indawo yezicelo

Iintambo ezifakwe kwi-mineral zisetyenziswa ngokubanzi kuzo zonke iindlela zobomi, ngakumbi kubandakanya:
(1) Izakhiwo eziphakamileyo: ezisetyenziselwa ukukhanyisa ngokubanzi, ukukhanyisa ngokukhawuleza, i-alam yomlilo, iintambo zombane zomlilo, njl., ukuqinisekisa ukuba umbane oqhelekileyo unokubonelelwa kwiimeko zongxamiseko.
(2) Ushishino lwepetrochemical: Kwiindawo ezinokuba yingozi kugqabhuko-dubulo, ukuxhathisa okukhulu komlilo kunye nokumelana nomhlwa kweentambo ezifakwe kwi-mineral insulated kuzenza zibe zezifanelekileyo.
(3) Uthutho: izikhululo zeenqwelo-moya, iitonela ezihamba ngaphantsi komhlaba, iinqanawa kunye nezinye iindawo, iintambo ze-mineral insulated cables zisetyenziselwa ukukhanyisa ngokukhawuleza, iinkqubo zokubeka iliso lomlilo, imigca yokungena umoya, njl., Ukuqinisekisa ukusebenza ngokukhuselekileyo kwezibonelelo zendlela.
(4) Izixhobo ezibalulekileyo: ezifana nezibhedlele, amaziko edatha, amagumbi okulawula umlilo, njl., aneemfuno eziphezulu zokuzinza kokuhanjiswa kwamandla kunye nokusebenza komlilo, kunye neentambo ze-mineral insulated ziyimfuneko.

3. Ubume bemarike kunye nethemba lophuhliso

Ngokunyuka kwengqalelo kukhuseleko lomlilo, imfuno yentengiso yeentambo ezifakwe kwi-mineral insulated iyakhula. Ngokukodwa kwiiprojekthi zamandla avuselelekayo ezifana nelanga kunye nomoya, iintambo ze-mineral-insulated cables zisetyenziswa ngokubanzi ngenxa yeendawo zazo ezichasene nomlilo. Kuqikelelwa ukuba ngo-2029, ubungakanani bemarike ye-mineral insulated intambo iya kufikelela kwi-2.87 yeebhiliyoni zeedola, kunye nezinga lokukhula lonyaka elihlanganisiweyo (CAGR) le-4.9%.

Kwiimarike zasekhaya, kunye nokuphunyezwa kwemigangatho efana ne-GB / T50016, ukusetyenziswa kweentambo ze-mineral insulated cables kwimigca yomlilo kuye kwanyanzeliswa, okuye kwakhuthaza ukuphuhliswa kweemarike. Okwangoku, iintambo zamandla ezifakwe kwi-mineral insulated zithatha indawo enkulu yentengiso, kwaye iintambo zokufudumeza ezifakwe kwiminerali nazo ziyandisa ngokuthe ngcembe uluhlu lwezicelo.

4.Isiphelo

I-Mineral insulated cable idlala indima ebalulekileyo kuzo zonke iinkalo zobomi ngenxa yokumelana nomlilo obalaseleyo, ukuxhathisa ukubola kunye nokuzinza kokudluliselwa. Ngokuphuculwa okuqhubekayo kweemfuno zokhuseleko lomlilo kunye nophuhliso olukhawulezayo lweeprojekthi zamandla avuselelekayo, ithemba lemarike yeentambo ze-mineral insulated cables zibanzi. Nangona kunjalo, iindleko zayo eziphezulu kunye neemfuno zofakelo nazo kufuneka ziqwalaselwe ekukhetheni nasekusetyenzisweni. Kuphuhliso lwexesha elizayo, iintambo ze-mineral insulated cables ziya kuqhubeka zidlala iinzuzo zabo ezizodwa zokuhanjiswa kwamandla kunye nokhuseleko lomlilo kuzo zonke iindlela zokuphila.
