Iphepha le-NOMEXiyiphepha le-synthetic elimnandi le-amide polymer insulating elinezakhiwo eziphezulu zemishini, ukuguquguquka kanye nezakhiwo ezinhle zikagesi, ezingagcina izici zalo ngisho nasezingeni eliphezulu lokushisa, futhi lisetshenziswe kabanzi emishinini yokuphehla amandla, ama-transformer, imishini kagesi, i-electromechanical kanye nemishini yasendlini.
Kunezinzuzo eziyi-8 zephepha le-Nomex njengoba ngezansi:
1. Amandla e-dielectric engokwemvelo
Imikhiqizo yephepha ye-Nomex ye-calendered ye-insulating ingakwazi ukumelana namandla enkambu ye-voltage yesikhashana engu-18 ~ 40KV/mm, ngaphandle kokwelashwa okwengeziwe nge-varnish ne-resin.Ngenxa yokungaguquguquki kwe-dielectric ephansi yemikhiqizo ye-NOMEX, yenza inkambu kagesi phakathi kwe-insulation kanye nokupholisa umfaniswano owengeziwe.
2. Ukuqina komshini
Ngemuva kokufakwa kwe-calendering, i-NOMEX insulating paper inamandla impela, futhi inokunwebeka okuhle, ukumelana nokukhala kanye nokumelana nokuhuzuka.Futhi imikhiqizo emincane ihlale iguquguquka.
3. Ukuzinza okushisayo
Iphepha le-NOMEX le-insulating linemvume yesigaba sezinga lokushisa le-UL elingu-220°C, okusho ukuthi lingagcina ukusebenza ngempumelelo iminyaka engaphezu kwe-10 ngisho noma lihlala libekwe ku-220°C.
4. Ukuhambisana kwamakhemikhali
Iphepha le-NOMEX le-insulating ngokuyisisekelo alithintwa izincibilikisi eziningi, futhi libonisa ukumelana okuhle nokugqwala kwe-asidi nokugqwala kwe-alkali.Ihambisana kalula nawo wonke ama-varnish, ama-adhesives, uketshezi lwe-transformer, izinto zokugcoba nezipholile.Ngaphezu kwalokho, iphepha le-NOMEX le-insulating ngeke lonakaliswe izinambuzane, isikhunta kanye nesikhunta.
5. Ukusebenza kokushisa okuphansi
Ngaphansi kwephuzu elibilayo le-nitrogen (77K), amandla aqinile we-NOMEX insulating paper T410, NOMEX993 kanye ne-994 wonke adlula inani lamandla ekamelweni lokushisa.
6. Ayizwani nomswakama
Lapho i-NOMEX insulating paper inomswakama ohlobene no-95%, amandla ayo e-dielectric angama-90% alokho esimweni esomile ngokuphelele, futhi ngesikhathi esifanayo, izakhiwo eziningi zemishini empeleni zithuthukisiwe.
7. Ukumelana nemisebe
Ngisho noma ukuqina kwemisebe ye-ionizing kufinyelela ku-800 megarads (8 megagrays), iphepha le-NOMEX lokuvikela alithinteki, futhi ngemva kwemithamo ye-8 yemisebe, lisagcina izakhiwo zalo zemishini kanye nogesi.
8. Non-toxic futhi ezivuthayo
Iphepha le-NOMEX le-insulating alikhiqizi noma yikuphi ukusabela okunobuthi okwaziwayo kubantu noma ezilwaneni.Iphepha le-NOMEX le-insulating alincibiliki emoyeni futhi alikusekeli ukuvutha.Ngaphezu kwalokho, inkomba yayo ye-oxygen ekhawulelwe (LOI) ku-220 ° C inkulu kune-20.8 (imvamisa ukuvutha okubalulekile komoya ongenalutho) inani), ngakho ngeke ishise.Iphepha le-Nomex insulating lihlangabezana nezidingo zokumelana nelangabi ezicaciswe yi-UL94V-0.
Empeleni, umndeni wephepha leNomex uhlanganisa izinhlobo ezithile ezihlukene, njengephepha elidume kakhuluNomex 410, bese kuba nguNomex 411, Nomex 414, Nomex 416, Nomex 464. Sizoxoxa ngezici ezengeziwe zezinhlobo ezahlukeneisihloko esilandelayo.
