Pamene miyezo yotetezera moto ikupitirira kukwera m'mafakitale monga zomangamanga, zoyendera sitima, malo osungira deta, mankhwala a petrochemical, ndi mphamvu zongowonjezwdwanso, Mineral Insulated (MI) Cables yakhala njira yabwino kwambiri yogwiritsira ntchito magetsi ofunikira chifukwa cha kukana kwawo moto komanso kudalirika kwawo kwa nthawi yayitali.
Poyerekeza ndi zingwe zamagetsi zachizolowezi, zingwe za MI zimatha kusunga umphumphu wa dera panthawi ya moto, kuonetsetsa kuti magetsi akupitilizabe kuzinthu zofunika monga mapampu ozimitsa moto, magetsi owunikira mwadzidzidzi, ma elevator, ndi zida zina zotetezera moyo.
Kwa opanga mawaya, magwiridwe antchito a mawayawa samangodalira kapangidwe ka mawayawa komanso mtundu wa zipangizo zomwe zimagwiritsidwa ntchito. Magnesium oxide (MgO), ma conductor a mkuwa, zigoba zamkuwa zopanda msoko,tepi ya mica, tepi yagalasi ya ulusi, ndiMankhwala a LSZHZonsezi zimathandiza kwambiri pakudziwa momwe chingwecho chingagwiritsidwire ntchito, momwe chingatetezere moto, komanso momwe chingadalire kwa nthawi yayitali.
Kodi Chingwe Chotetezedwa ndi Mineral (MI) N'chiyani?
Chingwe chachikhalidwe cha MI chimakhala ndi chowongolera cha mkuwa, choteteza cha magnesium oxide (MgO) choyera kwambiri, ndi chivundikiro cha mkuwa chopanda msoko kuti chiteteze makina.
Popeza kuti chotetezera chake chimapangidwa ndi zinthu zopanda chilengedwe osati ma polima oyaka, chingwe cha MI sichipanga utsi kapena mpweya wowononga panthawi ya moto pomwe chimasunga chotetezera chamagetsi chabwino kwambiri. Izi zimapangitsa kuti chikhale njira yogwiritsidwa ntchito kwambiri pamakina a chingwe osapsa ndi moto.
M'zaka zaposachedwapa, zingwe zofewa zoteteza ku mineral zakhala zikutchuka kwambiri. Mapangidwe awa nthawi zambiri amakhala ndi tepi ya mica, tepi yagalasi ya fiber, ndi mankhwala a Low Smoke Zero Halogen (LSZH) kuti apereke mphamvu yabwino kwambiri yoyaka moto komanso akuwonjezera kusinthasintha kwa kuyika.
Ubwino wa Ma Cable a MI
Ubwino waukulu wa zingwe za MI ndi kukana kwawo moto kwambiri. Ngakhale zikayaka moto, zimatha kusunga umphumphu wa dera ndikupitiliza kupereka magetsi ku makina otetezera ofunikira.
Chigoba cha mkuwa chopanda msoko chimaperekanso mphamvu zambiri zamakanika, kukana kuwonongeka bwino, komanso kukana chinyezi, mafuta, ndi mankhwala ambiri, zomwe zimapangitsa kuti zingwe za MI zikhale zoyenera malo ovuta monga mayendedwe a sitima, malo opangira magetsi, malo opangira mafuta, ndi mafakitale.
Poyerekeza ndi zingwe zamagetsi zachizolowezi, zingwe za MI nthawi zambiri zimakhala ndi mphamvu yonyamula mphamvu yamagetsi yapamwamba, nthawi yayitali yogwirira ntchito, komanso zosowa zochepa zosamalira, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zofunikira kwambiri zomwe zimafuna kugwira ntchito mosalekeza.
Zofooka za Ma Cable a MI
Ngakhale kuti zili ndi ubwino wake, ma MI cables ali ndi zofooka zingapo.
Popeza amagwiritsa ntchito mkuwa wambiri pa kondakitala ndi chidebe, mtengo wa zinthu nthawi zambiri umakhala wokwera kuposa wa zingwe zamagetsi wamba, zomwe zimapangitsa kuti mtengo woyika ukhale wokwera kwambiri.
Zingwe zokhazikika za MI zachikhalidwe zimakhalanso ndi kusinthasintha kochepa, zomwe zimapangitsa kukhazikitsa ndi kutha kwa ntchito kukhala kovuta komanso kumafuna ukatswiri wowonjezera pakukhazikitsa.
Kuphatikiza apo, magnesium oxide (MgO) ndi yopyapyala. Ngati malekezero a chingwe sanatsekedwe bwino, chinyezi chimatha kulowa mu insulation, zomwe zimachepetsa kukana kwa insulation. Pachifukwa ichi, kutseka bwino malekezero a chingwe ndikofunikira kuti chikhale chodalirika kwa nthawi yayitali.
Kodi Zipangizo Zachingwe Zimakhudza Bwanji Kugwira Ntchito kwa Chingwe cha MI?
Kugwira ntchito kwa chingwe cha MI sikudalira kokha kapangidwe kake komanso ubwino ndi kusinthasintha kwa zipangizo zake za chingwe.
Magnesium oxide (MgO) yoyera kwambiri imapereka chitetezo chamagetsi chodalirika, pomwe ma conductor a mkuwa omwe amayendetsa bwino kwambiri komanso ma sheath a mkuwa osasokonekera amathandizira kuti magetsi azigwira bwino ntchito komanso kuti makina azigwira ntchito bwino.
Pa zingwe zofewa zoteteza ku moto ndi mapangidwe ena a zingwe zosapsa ndi moto, zinthu monga tepi ya mica, tepi ya ulusi wagalasi, tepi yamkuwa, ndi mankhwala a LSZH zimathandizanso kwambiri. Zinthuzi zimathandiza kukonza magwiridwe antchito a moto, kuteteza makina, kukhazikika kwa ntchito, kulimba kwa kapangidwe kake, komanso kusinthasintha kwa zinthu zonse.
Kwa opanga zingwe, kusankha zipangizo za zingwe zapamwamba zomwe zimagwira ntchito bwino komanso kusinthasintha bwino kwa ntchito kungathandize kukonza bwino ntchito popanga zinthu komanso kukulitsa kudalirika kwa nthawi yayitali komanso moyo wautumiki wa chingwe chomalizidwa.
Mapeto
Chifukwa cha kukana kwawo moto, mphamvu ya makina, komanso kudalirika kwa nthawi yayitali, zingwe za MI zimagwiritsidwa ntchito kwambiri mumakina oteteza moto, mayendedwe a sitima, malo osungira deta, zomangamanga zamagetsi, ndi ntchito zina zofunika kwambiri.
Nthawi yomweyo, zipangizo zofunika kwambiri za chingwe—kuphatikizapo magnesium oxide (MgO), ma conductor a mkuwa, zigoba zamkuwa zopanda msoko, tepi ya mica, tepi yagalasi ya fiber, ndi mankhwala a LSZH—zimakhudza mwachindunji ubwino wa kupanga, magwiridwe antchito a moto, komanso kudalirika kwa chingwe kwa nthawi yayitali.
Pamene kufunikira kwa makina a zingwe osagwira moto kukupitirira kukula, opanga zingwe akugogomezera kwambiri magwiridwe antchito a zinthu ndi kusinthasintha kwa ntchito. Kusankha zipangizo zoyenera za zingwe ndikuwongolera kapangidwe ka zingwe ndi njira zopangira kungathandize kukonza kusinthasintha kwa zinthu ndikukwaniritsa kufunikira komwe kukukulirakulira kwa njira zodalirika kwambiri za zingwe.
