I-cable conductor yezintambo zamaminerali yakhiwe kakhuluithusi conductive, kuyilapho ungqimba olufakwa ngaphakathi lusebenzisa izinto zamaminerali ezingaphili ezimelana nezinga lokushisa eliphezulu nezingashi. Isendlalelo sokuhlukanisa sisebenzisa i-inorganic mineral material, kanti i-sheath yangaphandle yenziwe ngayointuthu ephansi, impahla yepulasitiki engenabuthi, ekhombisa ukumelana nokugqwala okuhle kakhulu. Ngemva kokuthola ukuqonda okuyisisekelo kwezintambo zamaminerali, ungathanda ukwazi izici zazo ezibalulekile? Ake singene kulokho.
01. Ukumelana Nomlilo:
Izintambo zamaminerali, ezakhiwe ngokuphelele ngezinto ezingaphili, azibasi noma zisize ukusha. Awazikhiqizi amagesi anobuthi ngisho nalapho echayeke emalangabini angaphandle, aqinisekisa ukusebenza okuqhubekayo ngemva komlilo ngaphandle kwesidingo sokushintshwa. Lawa makhebuli awakwazi ukumelana nomlilo ngempela, ahlinzeka ngesiqinisekiso esiqinisekisiwe samasekhethi okuphepha emlilweni, aphumelele ukuhlolwa kwe-IEC331 ye-International Electrotechnical Commission's.
02. Ikhono Lokuthwala Okuphezulu Kwamanje:
Izintambo ezifakwe amaminerali zingamelana namazinga okushisa afinyelela ku-250 ℃ ngesikhathi sokusebenza okuvamile. Njengokwe-IEC60702, izinga lokushisa eliqhubekayo lokusebenzisa izintambo ezifakwe amaminerali ngu-105 ℃, uma kucatshangelwa izinto ezisetshenziswayo zokuvala uphawu kanye nezidingo zokuphepha. Naphezu kwalokhu, umthamo wabo wamanje wokuthwala udlula kude owezinye izintambo ngenxa ye-magnesium oxide powder's conductivity ephakeme uma kuqhathaniswa namapulasitiki. Ngakho-ke, ekushiseni okufanayo okusebenzayo, umthamo wamanje wokuthwala mkhulu. Emigqeni engaphezu kuka-16mm, enye ingxenye ephambanayo ingancishiswa, futhi ezindaweni ezingavunyelwe ukuthintana nabantu, izigaba ezimbili eziphambanayo zingehliswa.
03. Ukumelana Namanzi, Ubufakazi Bokuqhuma, Nokumelana Nokugqwala:
Ukusebenzisa izinto ezinomusi ophansi, ezingenawo i-halogen, ezingabambezeli ilangabi ekushiseni kuqinisekisa ukumelana nokugqwala okuphezulu (ukugqwala kwepulasitiki kudingekile kuphela ezimeni zokugqwala kwamakhemikhali athile). I-conductor, i-insulation, kanye ne-sheathing yakha into eminyene futhi ehlangene, evimbela ukungena kwamanzi, umswakama, uwoyela, kanye namakhemikhali athile. Lezi zintambo zifanele ukusetshenziswa ezindaweni ezineziqhumane, izinto ezivikela ukuqhuma ezihlukahlukene, kanye nezintambo zemishini.
04. Ukuvikelwa kokulayishwa ngokweqile:
Ezintamboni zepulasitiki, i-overcurrent noma i-overvoltage ingabangela ukushisa kwe-insulation noma ukuwohloka ngesikhathi sokulayishwa ngokweqile. Kodwa-ke, ezintanjeni ze-mineral insulated, inqobo nje uma ukushisa kungafinyeleli endaweni yokuncibilika yethusi, ikhebula lihlala lingonakalisiwe. Ngisho nasekuqhekekeni okuphazima kweso, izinga lokushisa eliphezulu le-magnesium oxide endaweni yokuphuka akwenzi ama-carbides. Ngemva kokusulwa kokulayisha ngokweqile, ukusebenza kwekhebula kuhlala kungashintshile futhi kungaqhubeka nokusebenza ngendlela evamile.
05. Amazinga Okushisa Okusebenza Aphezulu:
Iphoyinti lokuncibilika lokufakwa kwe-magnesium oxide liphakeme kakhulu kunelethusi, okuvumela izinga lokushisa eliphakeme lokusebenza elivamile lekhebula ukuthi lifinyelele ku-250℃. Ingasebenza emazingeni okushisa aseduze nendawo yokuncibilika yethusi (1083℃) isikhathi esifushane.
06. Ukusebenza Okuqinile Kokuvikela:
Umgodla wethusiyekhebula isebenza njengesendlalelo esihle kakhulu sokuvikela, esivimbela kokubili ikhebula ngokwayo ekuphazamiseni ezinye izintambo nezizibuthe zangaphandle ukuthi zingathinti ikhebula.
Ngaphezu kwezici eziyinhloko ezishiwo ngenhla, izintambo zamaminerali nazo zinezimfanelo ezifana nokuphila isikhathi eside, ububanzi obuncane obungaphandle, ukukhanya, ukumelana nemisebe ephezulu, ukuphepha, ubungane bemvelo, ukumelana nokulimala kwemishini, ukusebenza kahle kokugoba, nokubeka phansi okusebenzayo.
