Iintambo ezifakwe i-Mineral Insulated: Abagcini boKhuseleko kunye noZinzo

Intambo yeMineral Insulated Cable (MICC okanye MI cable), njengohlobo olukhethekileyo lwentambo, isetyenziswa kakhulu kuzo zonke iinkalo zobomi ngenxa yokumelana kwayo nomlilo okugqwesileyo, ukumelana nokugqwala kunye nozinzo lokuhambisa. Eli phepha liza kwazisa ulwakhiwo, iimpawu, amasimi okusetyenziswa, imeko yemarike kunye namathuba ophuhliso lwentambo yeminerali insulated ngokweenkcukacha.

1. Ulwakhiwo kunye neempawu

Intambo egqunywe yiminerali yenziwe kakhulu ngocingo oluphambili lwe-copper conductor, umaleko wokukhusela umgubo we-magnesium oxide kunye ne-copper sheath (okanye i-aluminium sheath). Phakathi kwazo, ucingo oluphambili lwe-copper conductor lusetyenziswa njengendawo yokudlulisela umbane, kwaye umgubo we-magnesium oxide usetyenziswa njengezinto zokukhusela ezingaphiliyo ukwahlula umqhubi kunye ne-sheath ukuqinisekisa ukusebenza kombane kunye nokhuseleko lwentambo. Umaleko ongaphandle unokukhethwa ngokweemfuno zesingxobo esifanelekileyo sokukhusela, ukuphucula ngakumbi ukhuseleko lwentambo.

Iimpawu zentambo egqunywe yiminerali zibonakala kakhulu kwezi zinto zilandelayo:
(1) Ukumelana nomlilo okuphezulu: Ngenxa yokuba umaleko wokukhusela wenziwe ngezinto zeminerali ezingaphiliyo ezifana ne-magnesium oxide, iintambo ezikhuselayo zeminerali zisenokugcina ukusebenza kakuhle kokukhusela kubushushu obuphezulu kwaye zithintele ngokufanelekileyo umlilo. Isiciko sayo sobhedu siya kunyibilika kwi-1083 ° C, kwaye ukhuseleko lweminerali lunokumelana nobushushu obuphezulu obungaphezulu kwe-1000 ° C.
(2) Ukumelana nokugqwala okuphezulu: ityhubhu yobhedu engenamthungo okanye ityhubhu ye-aluminiyam njengesixhobo seshelufu, ukuze intambo egqunywe yiminerali ibe nokumelana nokugqwala okuphezulu, ingasetyenziswa kwiindawo ezirhabaxa ixesha elide.
(3) Uzinzo oluphezulu lokudlulisa: Intambo egqunywe yiminerali inamandla okudlulisa kakuhle, ifanelekile kumgama omde, ukudluliselwa kwedatha ngesantya esiphezulu kunye nokudluliselwa kwamandla ombane aphezulu kunye nezinye iimeko. Inamandla amakhulu okuthwala umbane, ukulinganiswa okuphezulu kwesiphazamiso esifutshane, kwaye inokudlulisa umbane ophezulu kubushushu obufanayo.
(4) Ubomi obude benkonzo: ngenxa yokumelana nomlilo, ukumelana nokugqwala kunye nezinye iimpawu, ubomi benkonzo yeentambo ezigqunywe yiminerali bude kakhulu, ngokubanzi bufikelela kwiminyaka engama-70.

2. Intsimi yezicelo

Iintambo ezigqunywe ngeminerali zisetyenziswa kakhulu kuzo zonke iinkalo zobomi, kuquka:
(1) Izakhiwo eziphakamileyo: ezisetyenziselwa ukukhanyisa ngokubanzi, ukukhanyisa ngexesha likaxakeka, i-alamu yomlilo, imigca yombane yomlilo, njl.njl., ukuqinisekisa ukuba umbane oqhelekileyo usenokufumaneka kwiimeko zikaxakeka.
(2) Ishishini le-Petrochemical: Kwiindawo ezinokuba yingozi zokuqhuma, ukumelana nomlilo okuphezulu kunye nokumelana nokugqwala kweentambo ezigqunywe yiminerali kuzenza zibe zilungele.
(3) Ezothutho: izikhululo zeenqwelo-moya, iitonela zendlela ezingaphantsi komhlaba, iinqanawa kunye nezinye iindawo, iintambo ezigqunywe ngeminerali zisetyenziselwa ukukhanyisa ngexesha likaxakeka, iinkqubo zokujonga umlilo, imigca yokungenisa umoya, njl.njl., ukuqinisekisa ukusebenza ngokukhuselekileyo kweendawo zezithuthi.
(4) Izibonelelo ezibalulekileyo: ezifana nezibhedlele, amaziko edatha, amagumbi olawulo lomlilo, njl.njl., zinemfuneko ephezulu yozinzo lokudluliselwa kombane kunye nokusebenza komlilo, kwaye iintambo ezigqunywe ngeeminerali azinakubalwa.
(5) Indawo ekhethekileyo: itonela, isiseko kunye nezinye iindawo ezivaliweyo, ezifumileyo, ezinobushushu obuphezulu, ukumelana nomlilo wentambo, iimfuno zokumelana nokugqwala ziphezulu, intambo egqunywe ziiminerali inokuhlangabezana nezi mfuno.

3. Imeko yemarike kunye namathuba ophuhliso

Njengoko ingqwalasela isanda kukhuseleko lomlilo, imfuno yemarike yeentambo ezigqunywe ngeminerali iyanda. Ingakumbi kwiiprojekthi zamandla avuselelekayo ezifana nelanga nomoya, iintambo ezigqunywe ngeminerali zisetyenziswa kakhulu ngenxa yeempawu zazo ezingatshiyo. Kuqikelelwa ukuba ngo-2029, ubungakanani bemarike yeentambo ezigqunywe ngeminerali kwihlabathi liphela buza kufikelela kwi-$2.87 yeebhiliyoni, kunye nezinga lokukhula lonyaka elihlanganisiweyo (CAGR) le-4.9%.

Kwimarike yasekhaya, ngokusebenzisa imigangatho efana ne-GB/T50016, ukusetyenziswa kweentambo ezigqunywe yiminerali kwiintambo zomlilo kuye kwaba yimfuneko, nto leyo eye yakhuthaza uphuhliso lwemarike. Okwangoku, iintambo zombane ezigqunywe yiminerali zithatha indawo ephambili kwimarike, kwaye iintambo zokufudumeza ezigqunywe yiminerali nazo ziyanda kancinci kancinci uluhlu lwazo lokusetyenziswa.

4. Isiphelo

Intambo egqunywe yiminerali idlala indima ebalulekileyo kuzo zonke iinkalo zobomi ngenxa yokumelana kwayo nomlilo okugqwesileyo, ukumelana nokugqwala kunye nozinzo lokudlulisela. Ngokuphuculwa okuqhubekayo kweemfuno zokhuseleko lomlilo kunye nophuhliso olukhawulezayo lweeprojekthi zamandla ahlaziyekayo, amathuba emarike eentambo ezigqunywe yiminerali abanzi. Nangona kunjalo, iindleko zayo eziphezulu kunye neemfuno zokufakela nazo kufuneka ziqwalaselwe ekukhetheni nasekusebenziseni. Kwixesha elizayo uphuhliso, iintambo ezigqunywe yiminerali ziya kuqhubeka zidlala iingenelo zazo ezikhethekileyo zokudlulisela umbane kunye nokhuseleko lomlilo kuzo zonke iinkalo zobomi.
